The Black Hole Information Paradox with Brian Cox #shorts

information is conserved in the universe

as far as we know so every law of nature

that we have says that information is

conserved so let's say that I take a

book and I set fire to it I incinerate

it I destroy it in any way that I can in

basic fundamental physics then it turns

out that if you could collect every

piece of that thing that I detonated or

incinerated every Quantum of radiation

every Photon every particle everything

in principle if I could just collect it

all then I Could reconstruct the thing

that I had destroyed the problem was

black holes quantum mechanics general

relativity when you put them together

you have this apparent prediction that

these things erase information from the

universe this became known as the black

hole information paradox
