do we exist inside whatever happens inside a black hole

it would explain a lot of stuff

wouldn't it?

None of that footage is real...please stop believing in cgi and bullshit theories made by (((academics))).

Isn't there basically just a lot of matter and pressure inside a black hole?

Its true, the universe is in fact only a reverse black hole, haha suckers you're all trapped in my orb !

depends, supermassive black holes have less total density than water inside their event horizon, and there's no limit on their size

Why would it make a difference?

No one knows what happens right AT the Singularity but, so far, no obvious signs of tidal forces tearing things apart. The galaxy is falling freely without any indication we're caught in a non-uniform gravity field.
And a uniform field is no different from no field. So it doesn't matter.

The start of the video is nice but it always annoys me to see the Bang portrayed like 10 kgs of TNT with all sorts of flame and turbulence on the surface of the fireball. None of that happens in a vacuum, no more than you see dust puffs hanging where the Apollo astronauts put a foot down.

Wouldn't the Universe then be a White Hole?

Not really, a white hole is just a time reversed black hole, so it would be a region from where space expands faster than light, instead in the Universe space expands everywhere equally, the scale factor gets bigger.

Except white holes are just mathematical trickery. (I hate to write that. It's often used on /sci/ as a "none of this shit exists" meme and I don't want it taken in that sense.)

Someone falling through the event horizon of a BH passes it and continues onwards to destruction in finite time. That's by his own watch. But he sees the entire history of the universe unreel in the photons which fell in AFTER him. An infinite amount of time passes in "flat" space during his final approach to the event horizon.

"Run the movie backwards" and it takes an infinite amount of time for anything to come out of a newly formed white hole. Which is another way of saying "they don't form".

>he sees the entire history of the universe unreel in the photons which fell in AFTER him

no, he won't, if you follow his path through the event horizon on a spacetime diagram you'll see that future photons never reach him before he reaches the "singularity"
someone staying outside the black hole never sees the guy passing the event horizon sure, but that's only because the guy's photons cannot escape, it doesn't mean he's still there, he has long fallen through and into the "singularity"

Not according to Kip Thorne.

I agree that he's not "hanging" at the horizon. That's an illusion. But in the last few meters of the fall SHORT of the horizon, billions of year pass "outside" and the light always catches up and passes him. It's faster than anything.
The view of the external universe is, however, incredibly distorted by the curved path the photons take.

Those photons are not infinitely blue-shifted (as they would be if the victim managed to hover with rockets above the horizon) but I imagine the sheer number of them would crisp him. Assuming he's not already dead for several other reasons.

>>9569250
he should be just fine falling into a supermassive black hole, and i don't see anything special happening to him as he passes the event horizon if he's in free fall

>> No.9569349

>>9569255
You're right. Nothing special at the event horizon of a supermassive hole. Not in the way of tidal forces anyway.
Dying comes later.
