Did time ever start? Can it just always have existed or something?

Hell, does it even exist? What if there is no past or future, and just a continuous present we all just move into, and whatever event or action or anything that happens is gone as soon as it occurs? Educate me /sci/, this is not a troll but a dilemma that's confusing the fuck out of me.

It really doesn't matter. Though I couldn't tell you much on the subject.

>> No.1878925

The past doesn't exist because it's over with
The future doesn't exist because it hasn't happened yet
The present doesn't exist because by the time we observe it, it's already in the past, which doesn't exist.

Therefore, nothing really exists.

The concept of time is still not really understood and there seems to be no real effort to investigate that. We do have quite an understanding of how space and time are linked, other than that: tough luck.

On the other hand, space and time are equivalent and it's just our stubborn way of thinking that seems to have a problem, the rest of the universe is quite cool with it.

Presentism is inconsistent with general relativity. Look it up, follow links, learn about physics.

Spoiler: universe is a 4 dimentional block-space, all-existing and static.

Keep your nihilism out of here.

The concept of time was just invented by humans so that they could figure out how old things are or when things happen or are going to happen. What we perceive as time is always moving forward, but couldn't have started and can't stop, since its only a measurement of the number of units of time have past or will pass.

He who controls the past controls the future.

Well kind of when some nut discovered it or something. But that's pretty much the start of our understanding of math.

No one knows. Those who say they do are bullshitting. I shall now proceed to bullshit: The universe has been doing what it does for all eternity, that is erupting forth from a single, impossibly dense point, where it expands for a few hundred billion years, and then slowly shrinks. Eventually the shrinking accelerates, and again the universe is one single impossibly small point, but this doesn't last long. Like a ball thrown hard into a wall, it quickly reverses, once more expanding. And so the cycle repeats, some cycles form more planets then others out of the endless clouds of hydrogen mostly, some cycles don't. And so it continues, the cycle of expansion and retraction, as it has for hundreds and hundreds of centillions of years. Or I could be full of shit.
