is information lost ?

Entropy always increases -> structure always decreases -> information is always lost

Information = energy = mass

A far enough developed ayylmao (a.k.a. God) can transform one into another.

So nothing is lost, it is just transformed into another state.

Wrong.

Oh... you can't? That's so sad...

You are retarded in the literal sense.

I'll bite for fun though: energy is one component of the energy-momentum tensor. It contains a mass term. That means mass contributes to the total energy content of a spacetime point. Energy exceeds the part contributed by mass though, so, they are not the same thing.
I doubt you even halfway understand the relation between information and entropy.

Yes cos there's random stuff happening such as radioactive shit which can't be traced backwards

No. If your shit's not time-reverse symmetrical (hello Copenhagen) then it's bullshit.

Are black holes filtering the increasing entropy so that the entropy levels of the universe stay the same?

>> No.11026056

Yes every generation has to learn the same things over and alot of info people learn over their lives is never communicated to others and dies with them. It's extremely hard to communicate meaningful concepts to populations. Let alone a single person.

We can turn mass into energy too bro. It's called fire.

>Entropy always increases
That is just a statistical rule of thumb. Any dynamical is recurrent on a long enough timeline

>> No.11026213

>>11026041
It is.

>Hurr entropy is like having an ordered deck and shuffling it. Now it is disordered!
Cool, but if I shuffle it long enough eventually I'll get my ordered deck back, decreasing entropy.

Put they are as far as statistical mechanics is concerned. The universe is described by the position and momentum of its particles.
