Why Does Time Exist at All? | Sean Carroll | English Subs

“Cosmologist Sean Carroll attacks — in an entertaining and thought-provoking tour through the nature of time and the universe — a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view of the nature of the universe, and our place in it.” TED Talks

“El cosmólogo Sean Carroll ataca - en un viaje entretenido y estimulante a través de la naturaleza del tiempo y el universo - una pregunta aparentemente simple: ¿Por qué existe el tiempo en absoluto? Las posibles respuestas apuntan a una vista sorprendente de la naturaleza del universo y nuestro lugar en él. TED Talks

The illusion of time : past, present and future all exist together

This video is from the documentary The Fabric of The Cosmos - for nonprofit educational purposes.
----
Please don't be misled by some comments below. This video does not say we can see future. It says Einstein's mathematical theory -which we later tested by clock experiment- also tells us that future and past always exist like the present! However, this does not necessitate pre-destination. Now is not deterministic as we know from Quantum Mechanics, so neither future nor past! Click to understand Quantum Mechanics. Wave functions evolve as time goes by. However, time does not collapse wave functions; observation collapses wave functions. Your wave function (which represents you) corresponding to your future has not collapsed yet. It will collapse in the future. As things in your life are probabilistic right now, they are probabilistic in the future too. Your past wave function has collapsed though. But your future one exists as a probability cloud in a sense. Here is a discussion I had with Avicenna10 about the topic (copy paste address below):

A comment from my exchange with axypolyas on why illusion of time does not require predestination:

+axypolyas Not sure why you are bothered by all these; perhaps it is because of your choices in life. Let me tell you something which will bother you more. You might know already, however, anyone who is reading this exchange will highly likely not.

The scientific description of you, me and everything is energy. We don't know what energy is. We can quantify it, however, in essence what is it? we have no idea. And energy takes different forms, like elementary particles, which in turn become atoms, molecules and part of the end result is us. We know energy is governed by laws and constants which naturally takes us to the inevitable conclusion: we are governed by those constants and laws. Before discovery of quantum physics, this would mean we are completely deterministic objects. Quantum physics showed us that we are not 100% deterministic. We are limited by laws but still we are unpredictable (we can calculate probabilities of what we might do next, but we don't know what we will do next until we do it). What do all these mean for us? Who are we? or what are we? Why do atoms and molecules pile up and make us? to live longer? All the atoms in our bodies are almost 15 billions of years old. What we call life is just another state in which they continue existing; nothing more; nothing special about it. How can we make sense of all these? Can we make sense of all these? If we are only, and only, condensed energy, there is no such a thing as making sense of things. There is only energy going through one state to another state mindlessly. Pretty scary and dark explanation of our existence, is the pure scientific one.

Science is only a tool; only a methodology we use to make sense of the universe. It does not tell us why things are the way they are. It tells us how we can construct theories and how we can use methods to test them, so that, we can do all these in an objective way. Science is an extremely limited way of looking into existence. Are my feelings objective? No. Are they scientific? No. Or, should I greet my neighbour every morning? Should I have an extra spoon of ice cream today? Or why do we do science? Do we have to do science? Say for our survival? Our survival has no meaning given particles making up our physical bodies existed for billions of years and they will continue to exist, perhaps longer.

I will jump to my personal understanding, rather than destroying ourselves using science. To me, existence of The Creator makes more sense than anything else, including my own existence. The Creator, who logically must (and interestingly described as such in Islam which I have chosen as a path to follow) be All-Knowing, All-Powerful, capable of creating a free agent (my soul for example) with life, creating a universe in which those free agents can grow up, examine, study, learn, make sense of it... freely... is the only logical answer I can think of. We don't see the Creator, or souls, or anything which would force us to believe and accept. Creator made us free and as part of making that choice freely, we will always be bothered by our existence, but we will never find an answer. That will remain as a matter of choice and it has always been like that.

The knowledge of truth as such is wonderful, but it is so little capable of acting as a guide that it cannot prove even the justification and the value of the aspiration toward that very knowledge of truth. Here we face, therefore, the limits of the purely rational conception of our existence. -- Albert Einstein

Where did English come from? - Claire Bowern

View full lesson:

When we talk about ‘English’, we often think of it as a single language. But what do the dialects spoken in dozens of countries around the world have in common with each other, or with the writings of Chaucer? Claire Bowern traces the language from the present day back to its ancient roots, showing how English has evolved through generations of speakers.

The Beginning of Everything -- The Big Bang

How did everything get started?

Has the universe a beginning or was it here since forever? Well, evidence suggests that there was indeed a starting point to this universe we are part of right now. But how can this be? How can something come from nothing? And what about time? We don't have all the answers yet so let's talk about what we know.

Also, we try to make this one not depressing. Tell us if we succeeded.



BY THE WAY. We have a website now. We'll try to blog from time to time, show you guys how we make the videos and give more insight to our process. Also we sell stuff. We really don't know where this whole kurzgesagt stuff leads us. But we are really thankful for all the attention and positive feedback and yeah, maybe we can make this our jobs -- it would be pretty nice and we could do more content each month. But we'll see. For now, thank you very much everybody for making this little adventure possible.



If you like the MUSIC of the video, you can get it here:
Thomas did an aweful good job again. :)

Next Video: April. (as soon as we can but we kind of have to make a living and visit college) Topic: Nuclear Energy (probably, if we finish the research in time -- if not something else)

Short videos, explaining things. For example Evolution, the Universe, Time, the Stock Exchange or controversial topics like Fracking. Because we love science.

Hunting for Dinosaurs Showed Me Our Place in the Universe | Kenneth Lacovara | English Subs

“What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus — a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet — and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.” TED Talks

¿Qué sucede cuando descubres un dinosaurio? El paleontólogo Kenneth Lacovara detalla su descubrimiento de Dreadnoughtus - un saurópodo de 77 millones de años que era tan alto como una casa de dos pisos y tan pesado como un jet jumbo - y considera lo increíblemente improbable que un pequeño mamífero que vive en las grietas del mundo de los dinosaurios podrían evolucionar en un ser sensible capaz de comprender estas magníficas criaturas. Únase a él en una celebración de la historia geológica de la Tierra y contemple nuestro lugar en tiempos profundos. TED Talks

Episode 1: Carol Tavris on Mistakes, Justification, and Cognitive Dissonance



For the first full episode of Mindscape, it's an honor to welcome social psychologist Carol Tavris. Her book with co-author Eliot Aronson, Mistakes Were Made (But Not By Me), explores the effect that cognitive dissonance has on how we think. We talk about the fascinating process by which people justify the mistakes that they make, and how that leads to everything from false memories to political polarization.

How humans could evolve to survive in space | Lisa Nip

If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on Earth — such as the ability to withstand radiation — to make humans more fit for exploring space. We're approaching a time during which we'll have the capacity to decide our own genetic destiny, Nip says. Augmenting the human body with new abilities is no longer a question of how, but of when.

What is the Shared Value Model? | Michael Porter | English Subs

TED Talks
“Why do we turn to nonprofits, NGOs and governments to solve society's biggest problems? Michael Porter admits he's biased, as a business school professor, but he wants you to hear his case for letting business try to solve massive problems like climate change and access to water. Why? Because when business solves a problem, it makes a profit — which lets that solution grow. TED Talks

Why Some Countries Are Poor and Others Rich

The reason why some countries are rich and others poor depends on many things, including the quality of their institutions, the culture they have, the natural resources they find and what latitude they're on. For gifts and more from The School of Life, visit our online shop:

Theoretical physicist Sean Carroll talks about the nature of EVERYTHING

---

The standard model of particle physics is a theory concerning the electromagnetic, weak and strong nuclear interactions which mediate the dynamics of the known subatomic particles. Developed throughout the early and middle 20th century, the current formulation was finalized in the mid 1970s upon experimental confirmation of the existence of quarks. Since then, discoveries of the bottom quark (1977), the top quark (1995) and the tau neutrino (2000) have given credence to the standard model. Because of its success in explaining a wide variety of experimental results, the standard model is sometimes regarded as a theory of almost everything.

Still, the standard model falls short of being a complete theory of fundamental interactions because it does not incorporate the physics of general relativity, such as gravitation and dark energy. The theory does not contain any viable dark matter particle that possesses all of the required properties deduced from observational cosmology. It also does not correctly account for neutrino oscillations (and their non-zero masses). Although the standard model is theoretically self-consistent, it has several unnatural properties giving rise to puzzles like the strong CP problem and the hierarchy problem.

Nevertheless, the standard model is important to theoretical and experimental particle physicists alike. For theoreticians, the standard model is a paradigm example of a quantum field theory, which exhibits a wide range of physics including spontaneous symmetry breaking, anomalies, non-perturbative behavior, etc. It is used as a basis for building more exotic models which incorporate hypothetical particles, extra dimensions and elaborate symmetries (such as supersymmetry) in an attempt to explain experimental results at variance with the Standard Model such as the existence of dark matter and neutrino oscillations. In turn, the experimenters have incorporated the standard model into simulators to help search for new physics beyond the standard model from relatively uninteresting background.

Recently, the standard model has found applications in other fields besides particle physics such as astrophysics and cosmology, in addition to nuclear physics.
