Gravity's effect on the flow of time in General Relativity

Explains how and why gravity affects the flow of time according to General Relativity.

Michio Kaku: The Universe in a Nutshell (Full Presentation)

What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

What is Space-Time ?

Space-time is the fundamental concept of the theory of relativity, a truly fusion of space and time with striking consequences. We present this idea in a very visual way. par Stéphane Durand Animations and computer graphics : Steve Michaud Shooting and video editing : Maxime Blaquière Musique : Matt Herskowitz Translation and English voice : Donald Dodier #FQXiVideoContest2014 To learn more about the spacetime concept and how it explains phenomena such as the slowdown of time and the contraction of lengths, you may consult the site "La relativité animée" (in French only for now but the English version is coming soon) : Or you can see directly its video content here : This way of presenting Special Relativity (with an Euclidian spacetime) was first published as an "interactive" book in 1999 : --- The video above (What is space-time?) is the French translation of this one : which is itself part of a series of 18 short videos about the physics of Time Travel : --- The site of Stephane Durand : .

Wallace Thornhill: The Long Path to Understanding Gravity | EU2015

In the theoretical sciences, it is commonly assumed that the role of gravity is settled. But as Richard Feynman observed, “There is no model of the theory of gravitation today, other than the mathematical form.” The problem is that mathematics will not account for the essential force in question. And yet, when theorists speculate about the big bang one conjecture is followed by another all building on the supposed supremacy of gravity as the driving force of cosmic evolution. In this talk at the EU2015 conference, Wal Thornhill takes us on a forty-year personal journey to understand the role of gravity in the electric universe.

The Amazing World of Gravity (Full Physics Documentary) | Spark

From the award-winning team that brought you The Secret Life of Chaos comes a unique television event on the physics of gravity, featuring unexpected historical insights, cutting- edge science and exciting new experiments. With the brilliant Professor Jim Al-Khalili as our host, we visit the LIGO lab in the USA where gravity waves were discovered, and uncover the latest theories about our cosmos that have come from studying the most intense sources of gravity imaginable – black holes. Elsewhere, Jim even uses Albert Einstein’s theories of special and general relativity to work out how the rate at which you age is affected by gravity and the speed at which you move about.
