Of all the unlikely ends of the universe, the Big Rip has to be the most spectacular. Galaxies ripped to shreds, dogs and cat first living together, then tragically separated by the infinitely accelerating expansion of space on subatomic scales. Good thing it's not going to happen. Or is it?

The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is, for the most part, nicely described with a constant density of dark energy - the same amount of this stuff in every block of space. Which means if you increase the volume you increase the overall amount of dark energy - hence accelerating expansion. Mathematically we describe a constant energy density with the cosmological constant in the equations of Einstein’s general theory of relativity. But what if dark energy is NOT constant? What if the energy density in each patch of space increases over time? In that case, the acceleration itself could be … accelerating. That would be bad.

Buttt..... Assuming the human race is past the Great Filter, and assuming w=-1.5, we would be so powerful in 22 billion years that we could do whatever we wanted with the universe.

the one thing l have an issue with is that ,in general ,when videos talk about hypothetical events 20+ billions of years in the future they still depict the solar system with earth as it is today ,and that's simply not correct since earth as we know it will be gone in about 1-2 billion years when the sun gets old enough to make the oceans boil and therefore life as we know it will cease to be

People like him talk about these things, come up with names such as dark energy, waste all this time talking about equations yet nobody actually has a clue how anything actually works. They don't know really know what is influencing the universe, they have no idea I'd it's whatever the universe is expanding into suckling or pulling it from the outside. 8f there is dark energy filling it they still have no idea what that even means or how it's forming. Basically all these people guess about things they don't understand and call it reality

We're falling into a black hole. It's the best explanation and explains this entire scenario. Also dark matter wouldn't be necessary anymore to a model of the universe.

Hello far future here are some questions I have you obviously won't be able to answer me. 1. Can space itself move and if so why and is there a constant value of space that isn't moving. 2. Is everything related to each other, like speed -emotions- is only valued because we can see something with a different speed. 3. ~

Do virtual particles in the cosmic horizon also interact similar to hawking radiation? That is, one virtual particle beyond the horizon and one inside of it?

This _completely_ explains why the earth is flat. It used to be round, but dark energy originated at the north pole. This caused the world to accelerate outwards, changing Antarctica from a continent to a vast 125,000 kilometer wall of ice surrounding the world. Also, the south pole has been stretched from a single point to a perpetually expanding omni-directional circle heading outwards in every possible direction. I suggest flat earthers everywhere move to antarctica. Past the _ginormously long_ icewall, in all directions, past the fake south pole, and utilize dark energy to grow into giants. Eventually you can become so big that you can defeat anything from pacific rim, and conquer the world. Alternatively, you could simply measure the Antarctica coastline. Using boats and equipment. I suppose this would be a simpler, faster, and far less costly way to prove how long it _really is._ Have fun.

You wouldn't be able to tell by looking at distant stars, whether the acceleration of the universe was accelerating, because then you are trying to judge the stars' distances away from us, velocity away from us, and figure out the cosmological redshifting its light experienced on its way here due to that varying accelerating expansion (it should expand the wavelengths of the photons themselves on the way here), all at the same time, and that's too many free variables to separate just from measuring its brightness and doppler shift of spectral lines. That's 3 free variables and 2 observations. You can't decide whether to attribute part of the observation to change in which of the 3 variables. It's not enough information.

How can the event horizon become smaller than the smallest possible structure I assume we are talking about the planck length. But if it is smaller then the planck length and time this must presumely mean that there are layers of reality below the planck length.

Don't worrie guys I'll save us as soon as the dark energy gets closer to earth right be for it true to rip it apart I the one shall streach forth my ass checks splitting them like the red see and let loose q fat with the atomic energy of 500 trillion nukeuler bombs and send that dark energy back to the dark empty void where it belongs

Is it just me, or is the video quality of Matt not quite right? I have it set to 1080P, but he still looks slightly "fuzzy". Small concern, of course, when compared to the death of the universe. ;-)

***Addendum*** If defined variables are contradictory they are null and void, Put simply to treat and work with nothing or "zero" or worse work with less than nothing "negative quanta's" such work is in fact illogical and thus Null and void, you need to work with something that is more than nothing, before you earn credit and thus have a Mathematical Proof..

Question here! Could it be that the Universe is not expanding but in fact falling in or/and spinning around the event horizon of a humongous black hole and things beyond the observable U already fell in?
