# Liberate all the matter from a black hole

So lets say that in my universe Dark energy would get stronger with time.

Could it liberate all the matter stucked on the black hole with suficient repulsive energy?

if not

What if i got dark energy of infinite repulsive energy?

What happens to the black hole????

Does all the matter gets liberated from the gravity of the black hole?

CRAZY i know...

Thought*(don't know how to edit the title)

Since it is your universe - you can make any rules you like.

Note, though, that a BH is not a place that matter gets sucked into - it is the result of having a lot of matter in one place. You don't hoover matter out of it like you are describing.

Why not? gravity is holding it there isnt it ? what if i got enaugh repulsive energy to overcome that gravity?

We cannot get infinite dark energy, and black holes are not thought to work that way, so your answer is no, we cannot get the matter out of a black hole.

You'd release a lot of energy.

The exact effect would depend on exactly how you went about it.
But what you just suggested is ironing space-time flat. What is gravity, anyway?
As Drakkith says - not how it works.

Set up the rules in your universe right and all that energy pops into existence as a big pink rabbit.

You seem to be imagining a black holes as a kind of bag of the sort you can take things out of... which is the main problem here. Other than your constraints being a little ... unconstrained. Remember - you can make up any kind of universe you like - perhaps you'll be happier in a sci-fi forum?

Otherwise: what is the physics you are trying to explore here?

i think that yes black holes are tought that way .
compact objects of infinite density holding all the matter that goes through the event horizon just like earth holds me to the ground, the only difference is that nothing can come out of its gravitanional attraction unless going faster then light.
I just dont see how a repulsive force stronger then the attractive force of a black hole could not free its matter of the gravitational attraction

Because the gravitational strength would get stronger as you get closer to the singularity if it exists. At that point it would take an infinite amount of force to disrupt the singularity.

a bag of the sort i can take things out of ...not really.
a compact object of the like of a star , yes

i see black holes for what they are, very dense object with immense gravitational force

So infinite repulsive energy VS infinite attractive energy

i wonder what would happen

Theoretical physics but you can call it science fiction.
Given that we know litle about dark energy and that it may or not get stronger with time i think that we need to adress the issue of dark energy and black holes. What if in trillions of years all that is left of our universe is supermassive blackholes scattered throughout the cosmos and that suddenly dark energy gets strong enaugh to release all the inormation that these black holes contain. Multi Big bang theory YES! thats the name of my theory!

Flights of fancy can be interesting but if you want to do any good for your own brain, you would likely find it more helpful to think about actual physics.

OK - show us the physics.

Our current laws of SR and GR prohibit infinities. Sorry.

The reason things cannot escape a black hole is that the escape velocity exceeds the speed of light.

Since no mass can reach, let alone exceed the speed of light, no amount dark energy or any other fanciful evocation can extract it.

PF forbids wild speculation. This thread is definitely wild speculation. ugalpha, please read the PF rules on overly-speculative posts.

I don't know how it survived 24 hours already but ... lock commencing... 10 ... 9 ... 8 ...

Great. When you publish it in a peer-reviewed journal, please be sure to return and point us at it, we will be very interested.

im not talking about anything beyond the event horizon escaping the gravity of the black hole. im talking about completly bursting it open with a stronger repulsive energy

Re: I think i found how to liberate all the matter from a black hole...tought experim

... lets see if I understand you:

if the universe goes through a stage where there are only SMBHs
if dark energy interacts with BHs to release their "information"
if dark energy increases

then dark energy may possibly increases enough to release this information
in which case, maybe you'd get a flood of degenerate energy.
... see the problem?

Can you support any of these ifs?

Now you seem to be thinking of dark energy as some sort of magic anti-gravity.
Perhaps you mean one of these:
... what you have described is a cyclic universe.

This is not science.

See post 15.

you sound more like a catholic inquisitor than a science advisor to be honnest.
