How would we detect a rogue black hole on route towards our solar system?

There are people that literally think these things exist. Yes, there are people that fucking stupid.

You ready to see me in all my glory, big boy?

Are there any places in the universe where it feels like only a few years have passed since the big bang due to such extreme speed/gravity well time dilation.

Since time slows down for an entity inside the event horizon, and everything outside is much faster, would an observer inside it see the end of the universe? It is said that the lifespan of a black hole is much, much bigger than the current age of our universe.

How can a black hole ever die if time stops completely at its core?

Think about it, outside the observable universe there is nothing but blackness, this could be the edges of the black hole.

All the atoms were pulled in from outside the black hole and rearranged to make the universe as we know it, starting with the big bang.

>black holes have a spatial singularity but allow free movement through time
>the universe has a temporal singularity but allows free movement through space

Holy shit we live in a mirrored black hole.

>the amount of that information that can be stored in a volume of space is proportional the surface area, not the volume

This is what theoryfags actually believe. Use some common sense. If I divide a sphere's interior into cubes of 1 plank lenght cubed, I can obviously store far more bits than can only be encoded on the surface

>/sci/ knows what happens once you get past the event horizon of a black hole
Damn why aren't you geniuses winning a Nobel?

How do you guys feel about powering near light-speed spacecraft using blackholes?

Sounds stupid, I know, however given that our understanding of how black holes work is correct we could create a blackhole (say, via a kugelblitz made using energy generated by a dyson sphere) we could throw an asteroid into it and use the energy generated by the hawking radiation, which is basically pure energy, which we could use for accelerate to near light-speed.

Does this sound reasonable, or is it meme-tier pop science?

This may sound like a stupid question, and it probably is, but why can't you orbit a blackhole (within the event horizon), and why wouldn't you break the speed of light falling into one.

From the little I know about orbital mechanics, surely falling into the event horizon, given a small amount of sideways velocity, you would pick up speed up, then swing around the singularity (or whatever you call it), then continue on your way outside of the blackhole, in an extremely elliptical orbit?

A hole's a hole.

What would happen if you went into one?

Brainlett here, black holes are basically magic right?
