If you’ve ever wondered, ‘What’s at the end of the universe?’ You’re not alone. Great physicists, such as the late Stephen Hawking and many other theoretical scientists, have been pondering this question for decades. However, the answer to that question is not so simple. We have some ideas of what might be past the so-called ‘end of the universe’, that boundary which everything in the observable universe slips past, never to be seen again. In fact, even our own galaxy and the billions of galaxies we can see are traveling towards this edge of the universe, and recently it was found that the universe is accelerating… pulled on by some unseen and mysterious force.

Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant? Join Matt on this week’s episode of Space Time as he explores the greatest expanses of our Universe. So what do you find when you reach the edge? More Universe? Bubble Universes? Back where you started?! Check out this episode of Space Time to find out!

What Is Beyond The Universe?

Scientists have found that the universe is expanding in all directions at once, but how can that be? And what is it expanding into?

The Universe Is Expanding Faster Than We Thought

Less than 20 years after the startling discovery that the expansion of the universe is accelerating -- a finding that led to a Nobel Prize in Physics for two teams of astronomers -- comes a potentially more jarring revelation that the cosmos is busting out in all directions even faster than predicted.

Cosmology safe as universe has no sense of direction

The new study, published today in Physical Review Letters, studied the cosmic microwave background (CMB) which is the remnant radiation from the Big Bang. It shows the universe expands the same way in all directions, supporting the assumptions made in cosmologists' standard model of the universe.

Universe Expanding Symmetrically, Real-Time Analysis Shows

The universe is expanding - and it is doing so at the same rate in all directions, according to new measurements that appear to confirm the standard model of cosmology.

What Would Happen If The Sun Suddenly Disappeared?


Have you ever wondered what might lie at the end of the universe? It’s amazing to imagine what it could be like at the very edge of the universe, what it looks like, what is out there. If it were possible to see this part of space, we would see the beginning of the universe as it began. But once something slips past the event horizon, it becomes lost to our sight, no longer giving off light signals.

Spacetime is a fascinating subject. One that needs to be explored to fully understand just how big the known universe is. So let’s take a journey to the outside of the known universe and answer: What Happens at The Edge of the Universe.

A Journey to the End of the Universe

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

Written and presented by Professor David Kipping.

By popular Space Fan request, I offer this video to help answer some of your questions regarding the expanding universe. Many of you consistently ask: If the universe is expanding, then what is it expanding into?

This concept is non-trivial to try and explain in a 5 minute YT video, but I do my best. I hope this helps!

In 100 trillion years the era of stars will be over.

We live in an unusual age – the age when the stars still shine. We should count ourselves lucky – nearly all of future history will be dark. But events will still unfold in that long, cooling darkness, and civilizations may endure. So how will the universe and its far-future denizens spend eternity?

Quantum Theory's Most Incredible Prediction


What does the future of our Universe hold? Alas Lewis & Barnes

Made by Kornhaber Brown (

In 100 trillion years the last star in the universe will expand the final atoms of its hydrogen fuel and settle quietly into a dim white dwarf, before slowly fading to black over as it radiates away its remnant heat. The era of stars will be over. That 100 trillion years is 10,000 times the current age of the universe, and so the days of starlight and warmth have a way to go. But even when they are done, the universe will be young in comparison to the long, dark ages to follow. In fact our universe will spend almost all of its infinite time in darkness, slowly crawling towards maximum entropy and ultimate heat death.

The Terrifying Way Our Universe Will End — And When

Our universe is racing toward its destruction as we speak. The end is not going to be especially pleasant, but when that end will happen is still a point of contention amongst cosmologists.

Three ways the universe could end - Venus Keus

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip.

--

We know about our universe’s past: the Big Bang theory predicts that all matter, time and space began about 14 billion years ago. And we know about the present: scientists’ observations of galaxies tell us that the universe is expanding at an accelerated rate. But what about the future? Do we know how our universe is going to end? Venus Keus explores cosmologists’ three possible scenarios.

Nigel Goes to Space

Join Nigel as he takes you on his journey to the stars and beyond!

Subscribe to Naked Science -

Nigel addresses one of the biggest questions, if the universe is expanding, how will it end?

The fate of the universe is determined by the density of the universe. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favours a universe that will continue to expand indefinitely, resulting in the Big Freeze scenario. However, observations are not conclusive, and alternative models are still possible, such as the “Big Rip”, or the “Big Crunch”.

Nigel is an internationally acclaimed science populariser and author, specialising in astronomy and space.
