why are things irreversible and why is time and entropy

what do you mean?

go read a book fagit

>why is time and entropy in one direction?

If it did change direction, would it be an observable event?

yeah but can you explain why some processes are reversible and some aren't and why entropy increases?

>>8477318
Say a star supernovas. Creates a fuck ton of neutrinos and blasts elements that it made it it's core out into the interstellar medium. How do you expect all of those elements to revert to star form, and then reverse the fusion process?

>>8477329
so this is probabilistic? just statistical?

>>8477318
>yes you can
total BS. If the entire universe reversed time and entropy all evidence of it would be erased. It's impossible. The passage of time on a universal scale could slow down, speed up, reverse entirely, and back again and we'd likely never know. The question that I'm asking is, could we know. Could we, say in 1million years with highly advanced theoretical technology measure the change of universal time. Is this event observable in our universe, and if it's not observable, would it really even mater?

what i asked there had nothing to do with time.

(op) take away the time bit

You mean like we did in the 60's with a glorified TV antenna?

sorry, you're going to have to explain that one to me

Because the universe is a semigroup.

Actually she put me into foster care at eight, because my grandparents had passed away and were the ones who had raised and looked after me. One of the downsides of having an Aspie parent, eh?

What do you get when you cross a joke with a rhetorical question?

They're not.

>>8477223
Because you're on the one-way moving travelator, going forward at the speed of light.

Get to the end, and get on a different one, if you want to go in another direction.

Because...
These chicks don't even know the name of my band...
But they're all on me like they wanna hold hands...
Cause once I blow they know that I'll be the man...
All because I'm the lead singer of my band...
