What Would a Journey to the Black Hole Be Like?

Today, I'm setting off on a journey toward the nearest black hole. But don't worry - I'll keep you in the know by live-streaming my entire adventure! I'll have someone to talk to during the flight, and he can help me if things get really tough! My travel buddy's name is Liam. Liam is a robot with artificial intelligence.

Space distances are seriously long. That's why traveling there would take way more time than you'd like to spend on the road! For example, Voyager 1, a space probe launched in 1977, was traveling out of the Solar System at a speed of 40,000 miles per hour. If my spacecraft moved at the same speed, it would take me a whole 77,000 years to get to the nearest star! But luckily, my spaceship is much faster than that. So let the journey begin!

#space #blackhole #brightside

SUMMARY:
- The International Space Station is the most expensive single object in the world. This money would buy you 250 Boeing 747s or two Louvre's with all the paintings and artwork inside!
- Among satellites, there are low and high flyers. And while the lowest flying ones move approximately 1,250 miles away from Earth, the highest reach 22,000 miles into space.
- Space distances are so vast, you can't even calculate them in miles. That's why scientists use the term astronomic unit, which equals 93 million miles – the distance from the sun to Earth. That means I'm 9.3 billion miles away from our planet!
- There's another trial ahead - the Oort Cloud. That means two things: first - we're on the outskirts of the Solar System; and second - we'll have to get through a cloud of icy objects orbiting the Sun at a distance of a 100,000 astronomic units!
- We're heading out of the Solar System just one-tenth of a light-year later. By the way, if you were trying to reach this point by car, the trip would take you more than 19 million years.
- In the center of pretty much every galaxy, there’s a supermassive black hole. For example, one is sitting right at the heart of our Milky Way galaxy, about 27,000 light-years away from Earth.
- A black hole is an eerie place where those laws of physics we studied at school stop working. If a massive star runs out of its star fuel, it becomes super-dense and buckles under its own weight, collapsing inward and bringing space-time along.
- I won't go further than the horizon, aka the point of no return. Once an object crosses this invisible line, it can't turn back, even if it's changed its mind.
- Liam says he's ready to start his journey. There he goes, bravely plunging toward the black hole while I'm recording everything that's happening to him.
- Liam just froze, as if a gigantic finger has pressed a pause button, and now, some force is stretching him thinner and thinner!
- It's the infamous spaghettification, which happens in a super-strong non-homogenous gravitational field!
- Liam is in a state of free-fall now, and feels no more stretching, scalding radiation, or gravity. Unfortunately, the connection is lost, and he can't tell me anything about the inside of the black hole.

A Journey to the End of the Universe

What will happen to us in the next few hundred years? Or a thousand? How will the Universe end? Nobody knows for sure, but we can gather all the existing theories together and find it out. Just a century from now humans will be the first living species outside Earth that we know of. In 1,000 years, humanity will accept technology not only in their lives but inside their bodies too. Ever heard about cyborgs? That’s exactly what every other human being will become in the future.

100,000 years in the future — and many of the constellations we know will become unrecognizable because of the natural movement of stars. At nearly the same time, Earth will celebrate the distant anniversary by a supervolcanic eruption, with hot magma and volcanic ash covering thousands upon thousands of square miles of land...

TIMESTAMPS:
Colonization of Mars 0:31
Will we become cyborgs? 0:49
Supervolcanic eruption 1:31
Mass destructions on Earth 2:07
Betelgeuse explosion 2:22
What will happen to Mars? 2:36
When will life on our planet cease to exist? 3:21

There will be no new stars 4:52
The Degenerate Era 5:10
The Black Hole Era 6:33
The era when time won’t matter 7:19
Birth of a new Universe 7:48

SUMMARY:
- In 100 years, technology will leap forwards, and we’ll all become part of a web larger than the Internet. We’ll also finally start colonizing nearby planets, most likely Mars.
- And here goes… 10,000 years from today. Antares, the red supergiant star that is fifteenth brightest in our night sky, will explode in a supernova.
- 100,000 years in the future — and many of the constellations we know will become unrecognizable because of the natural movement of stars.
- In 500,000 years, our planet will be struck with a huge boulder from the sky: an asteroid of about a half mile in diameter. If humans don’t find a way to avoid the impact, it will cause mass destructions on Earth.
- In 1 million years, two out of four moons of Uranus will collide with each other, causing chaos on the planet.
- Just 400,000 years later, Phobos, one of Mars’s two satellites, will break apart because of increasing gravity, and the red planet will have its own set of rings, just like Saturn.
- 110 million years from now is when the Sun will become 1% brighter. It will change the climate on every planet in the Solar system, ever so slightly making it hotter and hotter still.
- 4 billion years from now the Milky Way galaxy will collide with the Andromeda galaxy.
- In 7.9 billion years, the Sun will become super-inflated and turn into a red giant, swallowing the closest planets — including the scalding hot piece of rock that was once Earth.
- In 100 billion years, the Universe will stretch so far and so fast that galaxies will become invisible from each other’s perspective.
- In 1 trillion years, new stars will stop appearing in space.
- In 100 trillion years, the Degenerate Era will begin. With no fuel to feed the new stars, they will simply stop forming at all, even if some tried at first.
- In 120 trillion years, only white and brown dwarf stars will remain where normal stars have once been.
- In 1 quadrillion years, all planets will be thrown out of their orbits and sent drifting in the cold, dark outer space.
- 1 quintillion years, and things that once were stars will also become ejected from their galaxies, wandering the empty Universe for the rest of their time.
- Now, for quintillions of quintillions of years, there will be nothing; this period is called the Dark Era, and time won’t matter at this point.
- The false vacuum has just inflated and heated up to extreme temperatures, exploding in the empty space and filling it with new energy.
- Giving life to the new universe — and possibly not even a single one. You know this event as the Big Bang. That’s how our Universe was born, and how it will probably be reborn after billions upon billions of years.

What Would a Trip Through the Past Be Like

Well, hello, there! I’m Fernando, Fern for short, and today’s my birthday! To celebrate this event, I'd like to take you on a journey through my life…. All 360 million years of it! The history of the planet where I (and you, for that matter) come from started about 4.6 billion years ago. Before I came around, a lot of cool stuff had already happened.

Oh, how interesting would it have been to see the first liquid water appearing on Earth 4.4 billion years ago. 3 billion years ago was when the first photosynthesizing bacteria appeared. The earliest land fungi that started growing 1.3 billion years ago are also worth mentioning. But I feel pretty bad for them when the land got completely covered with a thick layer of ice 850 to 630 million years ago! Glad I wasn’t around yet! So, guys, are you with me? It's gonna be fun!

#earthhistory #geochronology #brghtside

SUMMARY:
- 485 million years ago, jawless fish appeared. They were the first animals with real bonesю
- 370 million years back in the past, some plants developed special tissue that started to produce wood. That's how forests of tall massive trees appeared on Earth.
- While before this time sharks looked more like huge eels rather than deadly torpedo-shaped predators, they now have well-developed teeth and a whole variety of forms and shapes.
- A real reptile as you know them today doesn't appear until 305 million years ago. At around that same time, other kinds of reptiles started showing up: the ancestors of modern-day crocodiles, snakes, turtles, and tuatarasю
- More and more different species, including new kinds of fish, are appearing in the oceans. That was about 251 million years back.
- I remember seeing the first land dinosaur ever about 225 million years ago. It has a small head sitting on a long neck, and you have no idea how flexible this neck is!
- About 201 million years ago, I witness one of the most ---biggest events ever, and that's the Triassic-Jurassic Extinction. It wipes out countless animal species both on land and in the oceans.
- It's 155 million years ago, and I hear some annoying buzz. It's the first blood-sucking insect, also known as no-see-ums.
- The mass extinction occurred 65 million years ago. It wiped out all the dinosaurs and half of other animal species.
- Also, a million years after the extinction, with the giant reptiles out of the way, mammals become the dominant species.
- One day, approximately 60 to 55 million years ago, I see a bizarre creature. It has a long tail, climbs the nearby trees, uses its thumbs, and has a family! Later, I find out that it's the first primate.
- 35 million years ago I have to start fighting for my home – grasslands begin to expand and diversify, and I do my best to fend off the invaders.
- Starting 25 million years ago, it’s as if this planet exploded with life! The first deer, hyenas, giraffes, bears – my neighborhood got a lot noisier almost overnight!
- About 4 million years back in the past, I see one of the first creatures that look a little bit like you, my friend. It's an Australopithecus, believed to be your close relative.
- About 350,000 years ago, the first archaic humans called Neanderthals appear.

What Happens If You Fall Into A Black Hole?

►For all questions - RidddleMedia@gmail.com

A Mysterious Journey to the End of Space

Does the Universe have an edge? Where does space end? And what's beyond that point? The truth is we don’t know it. Not yet anyway. So let's imagine what a journey to the end of space would be like! Okay, year 2236. Space exploration is flourishing, and astronauts are the most respected professionals in the Solar System. Yet despite all technological advances, no sign of extraterrestrial life has been observed. Or rather, wasn’t… until two years ago.

The GSA — Global Space Agency — registered a repeating signal like no other. It was coming from a galaxy billions of light years away and moving. The decision was made to construct a one-of-a-kind spaceship, exceeding the speed of light, to explore the signal. But to reach its full speed, it has to be piloted manually. And these four individuals are now going on board the ship for the most important mission in history… perhaps never to come back.

Astronomers Might've Found a White Hole

What do black holes do? What do black holes really look like? The existence of black holes was predicted over a century ago with nothing but math equations. Now we’ve taken the first photo of one. But black holes still hold plenty of secrets. Like their even more mysterious mirror twins: white holes!

Imagine if we could record a black hole on video. Watch it pull in and consume any matter that gets too close, even light itself! Now take this recording and play it backward – this is what a white hole should be: the black hole’s “pushing away and matter-spewing” counterpart.

Journey to a Black Hole - Uncovering a Mystery | SPACETIME - SCIENCE SHOW

We are surrounded by an intangible infinity: a universe in which the Earth is merely a grain of sand on the shore of an ocean. But we are unravelling more and more of the secrets of the universe which surrounds us. And that includes black holes, bottomless pits like the jaws of hell which devour all material that comes too close to them. Even light has no chance of escaping from them. But how does a Black Hole form? Are there any near us? And can they pose a threat to us? A look at the universe presents us with pictures of fascinating and confusing beauty: landscapes of light and gas and stardust, formed by cosmic wind and radiation. Our telescopes are discovering more and more wonders of the universe. They are looking far out into space and thus far back into the past. The centre of our galaxy is marked by a super-heavy Black Hole: an astronomical object with an inconceivable gravitational pull. Nothing can escape from it. The black hole at the centre of our galaxy is known as Sagittarius A-star. Of enormous size, it devours everything while remaining totally invisible.

What if a Black Hole entered our Solar System? | #aumsum #kids #science

Firstly, Black hole's gravity will cause complete chaos in our Solar System. Orbits of Planets as well as Comets will be significantly altered. Initially comets and meteorites might start hurtling towards us. Later even the planets might start colliding with each other.
Secondly, even if a gigantic planet like Jupiter comes in the path of the Black hole it will be devoured.
Thirdly, if the Black hole comes near Earth, initially its intense gravitational pull will cause devastating earthquakes and volcanoes. When the Black hole reaches our orbit there will be nothing left but an uninhabitable magma-laden rock.
Lastly, our Sun might offer some resistance to start with. A gravitational tug of war might ensue. But eventually even our beloved Sun will be ripped apart to pieces.

What Would a Journey to the Earth’s Core Be Like?

What’s the most exotic destination you’ve been to? Hawaii? Australia, Hoboken, New Jersey? Well, today I’m setting off on a journey that’s way more unusual than that – down to the Earth’s core. And I’m inviting you to join me. It’ll be fun! The center of the Earth lies about 4,000 miles below its surface, so it’s gonna be a looong trip.

???? By the way, guys, be attentive! To make the journey even more fascinating, I've hidden something interesting in this video. Okay, I'll give you a hint - it's movie references! You definitely saw them because each of those films is iconic. Try to find them all and let everyone know you have a sharp eye in the comments! If you're a video game fan, there's a reference for you too. But this one is really difficult.

???? And, of course, there is a cat hidden in this video. Can you spot it? C'mon, prove you're much more attentive than most people! Do you accept the challenge? ????

#earth #geology #brightside

SUMMARY:
- The crust isn't really that thick. It’s roughly 21 miles thick and is made up of basaltic rocks that are under the sea, and granitic rocks that make up the continents.
- Nile Crocodiles dig the deepest burrows among all animals, so you can find them at 39 feet under ground.
- There are whole underground cities with shelters and catacombs in different countries. The deepest of them lies at 278 feet under Cappadocia in Turkey.
- Continental crust is about 2 billion years old and it covers about 40 percent of the Earth (yeah, the rest is oceanic crust).
- In 2004, a half-marathon was organized in the Bochnia Salt Mine in Poland. It was the deepest half-marathon ever – you don’t often see people running at a depth of 695 feet after all.
- The Earth’s crust serves as an electric blanket that covers the mantle. It’s rich in the radioactive elements uranium, thorium, and potassium, which produce heat!
- The oceanic crust is never too far, and its average depth is 4.3 miles. It covers around 60 percent of the surface of our planet, and is thinner, denser and younger than the continental crust.
- The pressure is getting more and more extreme, and it’s getting colder and colder down here. This is the deepest point where earthquakes are born – the ones that come from here are rare, and get pretty weak by the time they’ve traveled 435 miles up to the surface.
- At 1,814 miles deep, the mantle ends and the outer core begins. It’s a sunless sea of super hot liquid metal that’s about the size of Mars.
- Once every several thousand years, something happens in this layer: the magnetic poles reverse, and north and south change places.
- At 2,750 miles, the inner core welcomes you! It’s the hottest, innermost part of the planet.
- The inner core is nearly the size of the Moon, and makes up 2 per cent of the Earth’s mass.
- Not so long ago, British scientists found out that the inner core is relatively young – probably somewhere between 500 and 1,000 million years old, and that’s nothing in terms of Earth science.
- Now, for those of you who are thinking of packing your bags to go see the Earth’s core, I have some not-so-good news: it’s technically not possible yet, because there’s no way to survive the pressure and extreme heat that are waiting down there.

What's Inside A Black Hole? | Unveiled

What's Inside A Black Hole?
Subscribe:

Black holes are mysterious and bizarre objects in the universe that really have no explanation. In fact, we hardly know anything about what lies inside of a black hole. We know and understand what we see on the outside of a black hole, but we have no way of going inside one to take a look at what is really happening. Even if we sent a probe inside a black hole, it would not survive the journey, and there would be no way that the probe could transmit a signal outside once it had been sucked inside. This is because a black hole is the product of mass being squeezed together so densely, and so tightly, that it creates a gravitational pull that is so strong, that not even light can escape its grasp.

Supermassive black holes with masses millions to billions of times that of the sun are thought to lurk at the hearts of all galaxies in the universe. You may notice that when you see a photo of a spiral galaxy, such as the Milky Way, in the center of the galaxy is a giant mass of light, which many people would think looks like a massive sun.

But this is not light coming from the black hole itself. Remember, that light cannot escape the heavy gravitational pull. Instead, the light we see comes from the magnetic fields near a spinning black hole that propel electrons outward in a jet along the rotation axis. The electrons produce bright radio waves. Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy.

You’re probably asking, ‘well, what’s a quasar?’ A Quasar is the short name for ‘quasi-stellar object’ and is a very highly energetic object surrounding an actively feeding Supermassive Black Hole. In more basic terms, the Supermassive Black Hole in the middle of a galaxy feeds intermittently. As it feeds, gas swirls around it at incredible speeds and forms an insanely bright hot orbiting disk. And if the black hole is swallowing a large amount of material, this feeding is accompanied by gigantic jets of gas. These are called Quasar. They are essentially fueled by the Black Holes they orbit.

What If a Black Hole Entered Our Solar System Today

Our solar system is made up of eight planets, hundreds of natural satellites like moons, thousands of asteroids, and billions of comets. This beautiful space cocktail is constantly moving around our sun. But it could all be torn apart if just one stray black hole decided to drop by…

Yes, there’s been a lot of talk about black holes lately since Kathrine Bouman figured out how to take a picture of one. The closest black hole to our solar system is 10 to 13 times the mass of our sun, and it’s located 3,000 light years away. But what would happen if a black hole came into our solar system?

Music by Epidemic Sound

SUMMARY:
- Black holes actually huge amounts of matter crammed into a teeny-tiny space. As a result, they have an extremely strong gravitational pull. In fact, it’s so powerful that even light can’t escape once a hole gets its hands on it.
- A big fat star collapses, then boom, black hole. Those ones are called stellar mass black holes. But there are also mega monsters called supermassive black holes. Those ones can be found churning slowly at the centers of galaxies.
- If our galaxy, the Milky Way, decided to rearrange itself, putting us a few dozen light years away from the center where a supermassive black hole lives (instead of 26,000 light years away), we’d be doomed.
- But what about a stellar mass black hole? They appear when stars run out of their star fuel and basically fall into themselves. This only happens if a star is big enough, like 3-10 times bigger than our sun.
- Here’s the thing I find most terrifying – we wouldn’t notice the black hole until it’s too late! The only detail that could give away the approaching black hole is a slight blurring of distant stars due to the hole’s gravitational lensing effect.
- As the gravitational pull of the black hole approaches each planet, it’ll play tug-of-war with our sun, ripping them all to pieces. As soon as the black hole reaches the asteroid belt between Jupiter and Mars, we’ll start to feel its pull
- Before disappearing into the abyss, anything that falls into the gravitational pull of a black hole will go through a process called spaghettification.
- Basically, if anything gets too close to a black hole, before it falls in, it gets stretched waaaay out (like a spaghetti noodle!) due to the hole’s incredible gravity.
- According to scientific estimations, the odds of a black hole coming across our solar system, much less munching on our planet, are lower than the chance of winning the lottery ten times in a row.
- It turns out that almost all galaxies in the universe have their own supermassive black holes in the center of them. In some of these galaxies, the black holes can be billions of times more massive than our sun!

SUMMARY:
- At 65 ft, there’s a whole new world opening before your eyes: shallow coral reefs are standing beautifully not far from the shore.
- 130 ft is the depth where we say goodbye even to recreational scuba divers — it’s the maximum allowed for them.
- At 230 ft we meet whale sharks — the largest known fish species, weighing up to 60 tons.
- And now we’re entering the dark part of the ocean: at 490 ft, just 1% of the light from the surface reaches us.
- Going deeper now, and at 1,640 ft you’re going to see the last of the blue whales — no, not really the last of them, I mean, that’s the deepest they can swim.
- At the depth of 2,723 ft we have reached the point where the Burj Khalifa, the tallest building in the world, would not even show its tip on the surface if it were put underwater.
- The giant squid inhabits the depths of 2,950 ft. Just imagine the creature with eyes the size of frisbees!
- The Midnight Zone. The pressure here is so huge that, if you somehow end up being here without a submersible, you’ll simply be crushed in a couple of seconds.
- 4,200 ft down below, and we see the ferocious great white sharks — these ultimate predators feel great at such a depth.
- See those huge nets? That’s because we’re now at the depth of 4,900 ft where the “catch-all” fishing method is used.
- At 6,000 ft, if we were in the Grand Canyon, we’d be sitting at its lowest and deepest point.
- Now, if we’re really careful, then at the depth of 6,600 ft, we’ll be able to see the black dragonfish — a nightmarish creature that dwells in the deep and dark parts of the ocean.
- At 7,400 ft we’ll be saying goodbye to sperm whales — this is the deepest point they can dive.
- At 15,000 ft, the monsters out of your worst nightmares pop up.
- The black swallower can swallow prey that’s twice its size!
- And now the deepest and darkest part of the ocean begins: we’re diving into the Mariana trench. Officially, it begins at about 19,700 ft deep.
- Going lower and deeper, you won’t see any other kind of fish or vertebrate animal whatsoever — the pressure is just too much for such creatures.

What If You Fell Into a Black Hole?

What would the outcome be if you took a leap of faith straight into a black hole? We looked to Einstein and Hawking to ponder the scenario.

Say one day you were exploring space looking for a new planet for humans to inhabit, but came across a black hole and decided – why not check it out? Would you have any chance of survival? How would you get out if at all? Would you find a shortcut to another universe? Watch the video to learn about what would happen if you fell into a black hole.

What Would Happen If You Traveled Through A Black Hole

Science fiction films have long depicted black holes as portals through space and time or gateways to other dimensions. And now, physicists have found that black holes might be suitable for hyperspace travel after all.

Following is a transcript of the video:

Black holes skirt the line between science fiction and science fact. On the one hand, scientists have seen real black holes in action, consuming unsuspecting stars that pass too close. But where reality ends and fiction takes over is at the edge of a black hole – a place called the event horizon, where no spacecraft has ever gone.

So, whatever happens beyond that boundary, inside of a black hole, is anyone’s guess. Scientists agree that if you travel far enough into a black hole, gravity will eventually become so strong that it kills anything in its path. But sci-fi films are more optimistic, depicting black holes as portals through space and time or gateways to other dimensions. And it turns out, some scientists now think the sci-fi buffs may be onto something. Black holes might be suitable for hyperspace travel, after all; it just takes the right kind of black hole.

At the center of every black hole is a point of infinite density, called a singularity. It’s what gives black holes their strong gravitational pull. And for decades, scientists thought singularities were all the same, so anything that passed the event horizon would be destroyed the same way: by being stretched and pulled like an infinitely long piece of spaghetti.

But that all changed in the early 1990s when different research teams in Canada and the US discovered a second singularity called a “mass inflation singularity.” It still has a strong gravitational pull, but it would only stretch you by a finite amount, and potentially NOT kill you in the process, meaning, you might survive the trip through a black hole. More specifically, through a large, rotating black hole, which is where these types of singularities exist.

Now, astronomers obviously can’t travel through a black hole yet to test this theory. In fact, the best place to test this is at the supermassive black hole in the center of our home galaxy, the Milky Way, which is 27,000 light years away. Not conveniently close to the least.

Therefore, scientists instead run computer simulations to see what would happen if we did manage to reach an isolated, rotating black hole, and now, for the first time, a team of scientists at UMass Dartmouth and Georgia Gwinnett College has done exactly that.

Lior Burko: “You would feel a slight increase in temperature, but it would not be a dramatic increase. It’s just that you don’t have enough time to respond to the very strong forces. It would just go through you too quickly.”

He added that passing through a weak singularity is like quickly running your finger through a candle flame that’s 1,000 degrees Celsius. If you hold your finger in the flame long enough, you’ll get burned, but pass your finger through quickly, and you’ll barely feel a thing. Similarly, if you pass through a weak singularity with the right speed and momentum, and at the right time, you may not feel much at all.

As for what happens once you get through to the other side, no one really knows, but Burko has his own ideas. He says one possibility is that we’d arrive at some other remote part of our galaxy, potentially light years away from any planets or stars, but a second, and perhaps more intriguing, a possibility is that we’d arrive in a different galaxy altogether. That's if you even make it that far.

Scientists say more research is needed before we’re anywhere close to successfully traveling through a black hole. But when we are ready, one of the safest passageways might be the supermassive black hole at the center of our galaxy called Sagittarius A*, and it might just be our ticket out of the Milky Way.

Black holes aren't exactly a popular vacation destination. They feed on anything and everything that comes into their vicinity. They are dense, and unpredictably volatile. And they don't let anything, and I mean anything, escape their gravitational grasp.
