The Beginning And The End Of Time with Thomas Hertog and Erik Verlinde

Thomas Hertog is a Belgian cosmologist at KU Leuven university and a key collaborator of Professor Stephen Hawking. He received his master’s degree in physics from the KU Leuven and his doctorate from the University of Cambridge. He joined the University of California as a research fellow in 2002 and became fellow at CERN, Geneva, in 2005. In 2011 he returned to Belgium where he is currently professor at the Institute for Theoretical Physics of the KU Leuven. Hertog is also guest professor at the Kavli Institute for Theoretical Physics, Santa Barbara, visiting senior fellow at Trinity College, Cambridge, and affiliate member of the International Solvay Institutes for Physics, Brussels. At the KU Leuven Hertog leads a research team that investigates the physical nature of black holes and the big bang. In this context he has a longstanding interest in gravitational waves - ripples of spacetime once predicted by Einstein. Hertog leads Belgium’s participation in the European Space Agency’s first gravitational-wave mission and in Einstein Telescope, a future gravitational-wave observatory underground that may well be a game changer for Belgium. He has recently wrote the book "On the Origin of Time" about his theory of the origin of the universe and his journey with Stephen Hawking.
Erik Verlinde is a Dutch theoretical physicist and string theorist. The Verlinde formula, which is important in conformal field theory and topological field theory, is named after him. His research deals with string theory, gravity, black holes and cosmology. Currently, he works at the Institute for Theoretical Physics at the University of Amsterdam.
At a symposium at the Dutch Spinoza-institute on December 8, 2009 he introduced a theory of entropic gravity. In this theory, gravity exists because of a difference in concentration of information in the empty space between two masses and its surroundings; he also extrapolates this to general relativity and quantum mechanics. He said in an interview with the newspaper de Volkskrant,"On the smallest level Newton's laws don't apply, but they do for apples and planets. You can compare this to the pressure of a gas. Molecules themselves don't have any pressure, but a barrel of gas has." It appears that Verlinde's approach to explaining gravity leads naturally to the correct observed strength of dark energy.
He received the Spinoza Prize in 2011, the most prestigious research award in the Netherlands.
On the origin of time by Thomas Hertog
Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin. But his early work ran into a crisis when the math predicted many big bangs producing many universes, most far too bizarre to harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and I worked shoulder to shoulder for twenty years, developing a new theory of the birth of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time to our deepest roots, we were startled to find a deeper level of evolution, in which physics itself transforms until particles, forces, and even time itself fades away. Once upon a time, perhaps, there was no time?
On the end of time by Erik Verlinde
Our Universe expands and keeps expanding due to the presence of a mysterious substance called “dark energy”. As a result, the Universe has a horizon, like that of a black hole, at which the expansion velocity exceeds the speed of light. From our point of view space and time cease to exist at this cosmological horizon. At that point the gravitational laws take the same form as the laws of thermodynamics. I will argue that space and time, together with the gravitational force, should therefore be seen as being emergent from an underlying microscopic description of Nature. This new perspective on our cosmos promises to solve the mysteries associated with dark energy and explain other understood gravitational phenomena. It also means that a very long time in the future our notions of space and time will eventually disappear.

Spacial momentum + Temporal momentum = Total momentum. Matter (angular momentum) is a transitional phenomena that occurs between the Spacial and Temporal dimensions. I think of the Time dimension as Now and the Space dimension as Not Now.

Might as well. We are energy. We evolve into matter. We are human animals in that humans named animals in various species. We are actually intention that evolved into self realization. The past is intention. Mister Hertog knows a lot more than those of you that have negative comments. However - the word crazy is not a word that is logical. Nothing is crazy crazy is a lazy word.

I’m a particle- I’m many particles- you’re a particle - you are many particles - when I meet you - your particles alter my particles, when you meet me my particles alter your particles - those you met before me altered your particles - when I meet you my opinions of your particles are a collective. That collective is impacted by my collective. And that judgement becomes your reality and so forth. Example. I left a comment. I disliked several comments. The fact that I am here watching a video about theory - spoken by a man that knows a simpler way of explaining but because of judgement cannot do so as judgement impacts credibility. So I’ll say it. I was Marylin Monroe. I was Isaac Newton. I was many people. Now the proof is in the equation. The math is already there. Thomas has to simplify because most are ignorant and many think they are correct. I know reality as my intention is knowing of self. This is inclusive of all reality. Even those of you I don’t like

Gravity is based on size not mass. Simple Galilean relative motion has the earth approaching- expanding at 16 feet per second per second constant acceleration- the released object. “The Final Theory: Rethinking Our Scientific Legacy “, Mark McCutcheon for proper physics. Newton,Mach,Einstein ad nauseum irrelevant.

[@quantumcat7673]

As far as I know Einstein's theory of relativity has been proven correct on many aspects of it. It also clearly show that what warp spacetime is energy. The denser the energy the bigger the warp of spacetime. Matter is just a form of potential energy. Anything else is bogus.
