No, the Universe does not have an atmosphere.
We have several billion years before the sun expands (but not explodes) to engulf the earth.
Genes to not break down and make people into zombies.
As for Ceiling and floor, think of it more as a constantly expanding sphere, dissipating at an extraordinary rate.

lastly, does the Universe have an atmoshpere? how long do we have until the sun bursts?
how many years do we have left before our genes break down and we become zombies?

Before I worried about the sun expanding and swallowing the Earth, I'd worry about the Andromeda galaxy passing through our neck of the woods, tugging a bunch of comets, etc., out of the outer reaches of our solar system, to become crashed into us.

And this rate will continue to get smaller and smaller and the universe will continue expanding...
OR
The universe will eventually begin contracting due to gravity and another Big Bang will happen and thus the universe will begin anew.

Why does it have to expand into anything?

I thought on a discovery channel show it was said the sun had 100,000 thou or mill to go.
And also, our moon is moving away from the earth by inches each year. At some point that might toss us or change our rotation and path.
