Destoying the Universe with science?

Is it physically possibly hat humans will one day be able to destroy the universe so that nothing exists anymore?

Off course assuming any kind of future tech that could one day be possible i theory.

For instance, if you could find a way to haul black holes around, what would happen if you slammed say 20 of the massive ones in the galaxy centres together in one giant black hole?

Such a thing has never existed naturally I think.

Maybe it would get so much gravity that it could start a runaway process with the black hole sucking nearby galaxies in, rock stock and barrel, feed on these and get big enogh to suck all of matter in?
Have you read Universal War? If not, you'll love it!
The book by Bajram?

There's a lot of things out there called Universal War apparently :)
I don't see why not, though the forces involved in moving black holes around would be enormous because of a) the mass of the black hole, and b) the fact that whatever is doing the pulling would have to be far enough away from the black hole to avoid being sucked in.... so the force required to move a black hole would be greater than the force of gravity of the black hole. But who knows? (EDIT: I'm not an expert on destroying the universe, so what I have just written may be spectacularly wrong :p)
Pure wtf discussion. Question itself makes no sense, since in future humans can discover absolutely anything and do absolutely anything.
Current level of knowledge says there is completely no way we can destroy anything more than a planet. Even not a planet, considering that it must be single explosion.
The very best hope is probably rerouting asteroid or dropping part of moon.
P.S. And rerouting black holes it fantasy very far from physics.
I think it's unlikely for a pretty simple reason. Currently the universe is expanding. But don't think of this as expanding just on some border zone. It's expanding everywhere. And like pennies on a surface of a balloon, the further apart things are - the faster they're moving apart. And the really really bizarre thing is that this rate of expansion is accelerating.

And for another little mind blower, even at the current expansion rate there are galaxies that are racing away from us at a rate that is faster than the speed of light. Relativity is about the perceived speed of particles within space, not about the expansion of space itself. The galaxy isn't moving faster than the speed of light, but the distance between us is increasing at such a rate. That means some of these galaxies, which we can currently see, have already transmitted their last light that will ever reach us. They will, one day billions of years from now, permanently fade from existence from our perspective. Beautiful or sad depending on how you look at it.

Nothing within spacetime, even gravity, travels faster than light meaning that even if you had an infinite mass object, its infinite gravitational effect would never reach parts of the universe. So for instance if our sun suddenly disappeared nothing would change at all from our perspective for the 8 minutes it would take everything to propagate to us at the speed of light. So any sort of universe ending event seems improbable simply because nothing will ever be able to reach, let alone, affect all of the universe.
@OhNoMyPants

That is of course assuming that this expansion will continue to occur at least as 'fast' as the speed of light, forever

Do you study physics? Your explanation was very succint
OhNoMyPants very good point. The expansion puts a natural limit of how much of the universe we would be able to destroy. Anything "receeding" from us faster than the speed of light would seem safe, because we have no way of getting to it.

This lowers the bar. We could instead set the target at destroting everything we COULD reach, and eventually, no more light would reach the destruction zone so it would sorta be the same thing, if you happened to be in the DZ.
Why you can't reroute big holes? I know they are very very very big, but the bottom line is they are physical objects like anything else. And anything physical thing will move if enough energy is deployed.

Not sure how you'd do it, since it might suck in anything you tried moving it with? Are they magnetic?
Yes only imaginable way to affect black hole is gravitation and to do this you need you own stars with controlled motion. And level of energy here is completely out of current science (if we use term controlled).
I mean let's just concentrate on blowing up Earth, shall we?
