Astronomy - White Holes

[Charlie the Astronomy Addict No.9311533]

White holes. Do they exist? Do you think they exist? Let's discuss the possible theories about existence of White Holes.

[Anonymous No.9311544]

They don't exist
Just like black holes, which don't exist either

Except black holes have been detected.

[Anonymous No.9311574]

There's nothing in a black hole that indicates the presence of a wormhole.

A black hole is a region of existence where gravity goes haywire and sucks up everything except hawking radiation for some unexplained reason so there is no exit to a black hole only oblivion.

This.
But, we haven't detected any white holes, yet.

Hawking radiation is caused by virtual particle escape bro

At the edge of the event horizon, there exist virtual particles that form from the temperature of the black hole, which is some non-zero temperature.

Temperature is a measure of the energy of particles in a space. At a certain temperature the space is so infused with energy that energy condenses directly into particles (pair production).

Lets say a pair of virtual particles is created exactly at the edge of the event horizon. There is a non-zero, small chance that one of the particles will be ejected from the black hole and escape since it is located out of the event horizon.

This escaping particle was part of a pair, made from the energy of the temperature of the black hole.

In this fashion, a black hole's total mass is effectively drained to create new virtual particles that escape it. The process is VERY slow for any black hole of stellar mass or more, but if a small black hole existed (small schwarzchild radius) it would proceed fast enough to cause it to evaporate in seconds.

My explanation is probably very poor because i've been awake for 3 days studying but I hope it helped, there is a reasonable explanation to Hawking radiation escaping the pull of a black hole.

A white hole?

[Anonymous No.9311737]

I would say that nothing can 'get in' a wormhole. The math just does not say that.
So a black hole is a white hole too, in a superficial sense.

>Nothing in
So nothing below c can get past the event horizon, going in? So it must be repelling matter, and have negative gravity, which...doesn't exist?
(Or positive gravity, if you take normal gravity to be negative)

It's okay I got your joke bro
even kek a little

[Anonymous No.9312184]

We're in one.

Inside every black hole, the edge from the inside is the white hole.

All equations go up under this assumption too.

Preferably positive gravity yes. Actually saying that something doesn't exist is a big mistake. Our technology is just too ''simple'' now. Universe is a place of infinite possibilities that we cannot observe now. Maybe in few years we will be able to find something with positive gravity so extreme that nothing could ever get close to it. Even though it sound like utter bullcrap it is possible until technology says otherwise.
