   May 4, 2022 · Down there, nature is governed by quantum mechanics. This amazingly powerful theory has been shown to account for all the forces of nature, except gravity. When physicists try to apply quantum theory to gravity, they find that space and time become almost unrecognizable. They seem to start fluctuating wildly.

   Jun 18, 2024 · By Carin Cain June 8, 2024June 18, 2024. The concept of space existing without time challenges our understanding of the universe. Space and time are inextricably linked in the spacetime continuum, a unified entity where the properties of one influence the other. The interplay between gravity and quantum mechanics at the quantum scale, explored ...

   Can space explain time?

   • With space and time so intimately linked in relativity, any account of how space emerges must also explain time. “Time must also emerge somehow,” says Mark van Raamsdonk, a physicist at the University of British Columbia and a pioneer in the connection between entanglement and spacetime.

   What's outside the universe?

   • To answer the question of what's outside the universe, we first need to define exactly what we mean by "universe." If you take it to mean literally all the things that could possibly exist in all of space and time, then there can't be anything outside the universe.

   What does quantum physics say about space and time?

   • It doesn’t really have much to say about space and time at the very smallest scales. And that’s where the trouble really starts. Down there, nature is governed by quantum mechanics. This amazingly powerful theory has been shown to account for all the forces of nature, except gravity.

   What if space is made of entanglement?

   • If space is made of entanglement, then the puzzle of quantum gravity seems much easier to solve: instead of trying to account for the warping of space in a quantum way, space itself emerges out of a fundamentally quantum phenomenon. Susskind suspects this is why a theory of quantum gravity has been so difficult to find in the first place.

   Does space have energy?

   • (32:12) The next simplest thing you can do is add energy to it, but add only vacuum energy, energy of empty space itself. So there’s no particles or photons or anything like that. There’s just empty space, it has energy. We think that space does have energy now, we discovered this with the accelerating universe, in 1998.

   Does empty space have energy?

   • There’s just empty space, it has energy. We think that space does have energy now, we discovered this with the accelerating universe, in 1998. And the equations were solved back in 1917 by Willem de Sitter, a Dutch astrophysicist. So, if you have a positive amount of energy in empty space, you get a cosmological solution called de Sitter space.
