It's been nearly a century since scientists first theorized that the Universe was expanding, and that the farther away a galaxy was from us, the faster it appears to recede. This isn't because galaxies are physically moving away from us, but rather because the Universe is full of gravitationally-bound objects, and the fabric of space that those objects reside in is expanding.
But this picture, which held sway from the 1920s onward, has been recently revised. It's been only 20 years since we first realized that this expansion was speeding up, and that as time goes on, individual galaxies will appear to recede away from us faster and faster. In time, they'll become unreachable, even if we journeyed towards them at the speed of light. The Universe is disappearing, and there's nothing we can do about it.
When you look out at a star whose light arrives after traveling towards you for 100 years, you're seeing a star that's 100 light years away, due to the fact that the speed of light is finite. But when you look out at a galaxy whose light arrives after traveling towards you for a journey of 100 million years, you're not looking at a galaxy that's 100 million light years distant. Rather, you're seeing a galaxy that's significantly farther away than that!

Our whole existence and concept of the universe is just a dream a drunk alien is having in another reality.

I'm thinking flat.
In theory you could travel near the speed of light into the far future, then sit in Douglas Adams’ Restaurant at the End of the Universe and watch it all go foom while drinking champagne. The Universe will end not in the cold desolate heat-death of thermodynamics and utter darkness as the last star burns out. Instead it will be a beautifully spectacular ending, one that we can actually watch. Isn’t God’s plan great?
Champagne?
For me, Pangalactic gargle blasters are the only truly suitable drink for watching
I’ll be drinking a Pepsi
At Micky D’s.
Good question. It is. It is expanding into the unknown parts, but the absence seals not in stopping the expansion but in defining — defining that there is a part outside the expanding universe that the universe expands into.
Haha!
LOL, they certainly would. :D

The Universe Is Disappearing, And There’s Nothing We Can Do To Stop It
Just curious. The “Big Bang” something blew up. The if so there is another side opposite to us going the other way isn’t there?
An inquiring mind wants to know- what is beyond the edge of the “fabric” of the universe?
WHEN He comes in the air, the dead in Christ rise first, then we who remain are caught up together with them in the clouds, to meet the Lord in the air. You could be there too ...
We cannot cure the common cold, nor can we do anything to adjust the wind... and they want us to do something about the entire universe's motion??
You’ll find it after washing the overalls you wore the day you took them off with the key in the pocket.
It's my suspicion that the people who report on such things, mouth breathing journos mostly, aren't capable of understanding and explaining the science. They just in effect say "Astronomers tell us that when they look at distant stars they have concluded the expansion of the universe is accelerating over time" and then with their limited understanding of Physics, Stellar Distances, Light Speed, etc. somehow think the conclusion is based on those very distant stars moving faster than nearby ones. So the conclusion is mind boggling but the explanation for what led to it doesn't really make much sense.
If I was still in college I'd be able to knock on the door of the professor who conducted my Astronomy class (held, by the way, in the Planetarium of The OSU where on occasion he could just say "Let's turn down the lights and I'll show you" ... very friggin' cool!) and ask him for an explanation. But that's not an option anymore :-(
How do you feel about zero point energy?
