So what exactly makes time?

Good question. No one knows. Some people think it's related to the change in entropy of the universe. I dunno though.

It's one of those fundamental questions which most people just say "It just IS!"

Like why do we only perceive 3 dimensions? Why not 2? four? Why does gold look gold? Why does adding or subtracting a proton make an atom behave entirely differently? Why does the circumference of a circle equal pi?

Why does the circumference of a circle equal pi?

We've been contacted by species from another universe!

You know what I mean!

I haven't had enough coffee yet.

Why does gold look gold?

We know that already, though I forget what it was - I read an article about it a while ago. Something about relativic electrons in gold's outer orbitals, I think.

Ah, you mean this?

Well I guess we can check one off then.

Why does adding or subtracting a proton make an atom behave entirely differently?

We know that quite well as well. It's pretty basic (or acidic, if you excuse the pun) chemistry.

But most of those have good answers, are well studied and understood.

As for where time comes from, I recommend Stephen Hawking's "A Brief History of Time." But in general, the reason it 'goes in one direction' is because of entropy. Essentially, your brain (or any information processing system for that matter) needs to result in an increase in entropy. Information theory and thermodynamics are very deeply linked, which is generally the explanation behind that.

I didn't say those questions were unknowable, I said they're questions that most people don't ponder or attempt to solve.

What about fluctuations, then? If time was linked to "always increase entropy", then fluctuations wouldn't be a thing.

To be clear, an FTL message that you send cannot return to you before you send it.

Uh, only because a message is unable to change direction. If you have an ansible, and you have a relay moving relative to you with their own ansible, you can bounce messages back into your past.

Can you prove that? Which way is the ansible moving relative to me, away or towards? Either way they wouldn't reply to the message until I sent it, and I wouldn't get theirs until they sent it regardless of their movement? It just makes the simultaneity confusing; there exist reference frames in which the signal looks like its received and sent to me before I send the initial one, but that certainly isn't MY reference frame. Right? Wrong?

2 Year old youngest cryonically frozen patient.

She happens to be stored at the same place i've arranged my head to be frozen and stored. 

[Cryxis, Prince of Doom]

Has anyone ever sucessfully brought back a cryogenicaly frozen person?

[Cryxis, Prince of Doom]

.... But freezing completely destroys the cells if done wrong and why would we do something that we have very little proof of being able to work on human beings?
