   > 10 billion light years across where you can never see what's happening outside that Horizon around us because of the acceleration of the universe because of the Dark Energy pushing everything apart

   CLIFFORD JOHNSON: Perhaps the reason we hadn't noticed it before is because the way you measure it is in terms of how much is it per unit of space time. Perhaps a little chunk of space right here. So you have to divide the entire effect by the volume of the observable universe. So that makes it a very small number. NARRATOR: Imagine the energy released by a match head burning. (hissing, flame roaring) The estimated equivalent in dark energy is spread across a cube of empty space with an edge about seven and a half miles long-- or the amount of space contained by about one and half million Astr…

   Now to the uh proverbial uh the implications of the dark energy changing is are astonishing if indeed it's true. There are many things that can happen. The cosmological constant can slowly change sort of asmtoically changing to some value. It could get bigger. It could get smaller, right? It changes. It's not going to be a constant. It won't be a constant, right? So, the dark energy term will evolve. Can't evolve. We parameterize it by these two terms, omega or wa. Those are both the equations of state which govern the existence and the the net effect of the scale factor on distance. How the s…

   And that's pretty tough to work out in any way that makes sense because one of the insights of Einstein in general relativity is that the flow of time, although he didn't really use that language, but the rate at which time elapses is influenced by the conditions, by the matter and energy in some region of this larger reality. And so time here can be very different from time over there even in our universe, right? Time near a black hole, very different from the time that I'm experiencing right here. Now, if I was at the edge of a black hole, I wouldn't feel time behaving strangely because ever…

   So that such that when we observe light from a galaxy or from a supernova or from a barrier acoustic oscillation which is what Desi's measuring, we are not seeing it as it is right now. We're seeing it as it was when that light was emitted, propagated along light cones as light does. And then uh we can actually translate that back to the physical separation at the time of the emission or the physical separation today which called the proper distance. We have different proxies for those. Then we plug those into again the uh this this red shift distance relationship. And the startling thing is n…

   It would be like as though you had only ever experienced land, and then one day, you discover the oceans. NARRATOR: It's called "dark energy." Scientists now believe it's the most powerful force in the universe, expanding its very fabric, pushing galaxies apart, and it may even be driving the universe's ultimate fate. But it remains an enigma. We have absolutely no idea what dark energy is to this day. NARRATOR: How did our vision of the universe get completely overturned in just a few decades? And what new surprises might lie just over the horizon? JOHN JOHNSON: The past 50 years of astrophys…

   This raises the question of how far we can rely on extrapolating a theory to a new domain. For example, despite its success in describing objects moving with low relative velocities in a weak gravitational field, where it is nearly indistinguishable from general relativity, Newtonian gravity does not apply to other regimes. How far, then, can we rely on a theory to extend our reach? The obstacles to making such reliable inferences reflect the specific details of particular domains of inquiry. Below we will focus on the obstacles to answering theoretical questions in cosmology due to the struct…

   There'd be no difference between up and down. There's no arrow of space out in the middle of in between the planets where there's no gravitational field. The modern viewpoint is that the arrow of time is exactly the same way. Just as the arrow of space can be traced to the fact that we live in the vicinity of an influ in influential object, the earth, the arrow of time can be traced to the fact that we live in the aftermath of an influential event, the big bang. 13.8 billion years ago, the universe was hot, dense, and smooth. You go through the equations, you figure out that's very low entropy…
