What happens if a universe is destroyed?

Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Rather than meeting its end through fire and brimstone, the cosmos will likely succumb to “heat death.” Astronomers call it the Big Freeze.

Is it possible to go out of the Universe?

You can’t leave the universe by using the present space technology. But if you can manage a spaceship with a speed of light then you can explore outer space beyond human knowledge but its impossible for anything to gain the speed of light so you can’t leave the universe.

How can we destroy things in the universe?

If you’re out to destroy things, you’ve got plenty of options. For a modest-sized clump of matter — like say, planet Earth — there are a number of ways, many of which are completely natural, for the Universe to obliterate it. Bring our world close enough to a large black hole, and it will simply be ripped apart and devoured.

Can we destroy the universe with the Higgs?

Image credit: C. Faucher-Giguère, A. Lidz, and L. Hernquist, Science 319, 5859 (47). But if you wanted to destroy the Universe, relying on the Higgs is a fool’s game. The smart money is to bet on cosmic inflation, and to remember that the only reason our Universe exists as it does is because inflation came to an end.

Why is it bad that we can’t see the Big Bang transition?

It’s bad because we’d never be able to see it coming; all the observable signals of the Universe propagate no faster than the speed of light in vacuum, and so if the transition is propagating at that speed, we’d have no signal of it before it was on top of us.

Is the speed of light changing in the universe?

But it’s also good, because the Universe is accelerating in its expansion, meaning that — for 97 \% of the observable Universe — a signal propagating at the speed of light will never reach us. So even if the transition happens somewhere in our Universe, it’s unlikely to affect us.
