Philosophy + Physics Questions

Bad combination, I admit...

So, I'll start by posting a question of mine, and the answer i consider possible.

Q: Is Time included in the layer of the universe, among the planets, or does it exist independently.

Now the answer might look simple as in: "Of course it's independent". BUT, we humans cannot fully perceive this 4th dimension, sooooo, we cannot see the entire universe. Now imagine we could perceive time as a "flowing" line. It would be all around us affecting us.

A: I believe time is not independent. EVERYTHING, like length, width and depth, are part of the UNIVERSE which includes everything. Outside it, there is nothing.

physics have multiple theories developed thru decades, all of wich from the very first stages, have incorporated time as one of the dimensions of the universe.

Time exists as an independent force because everything experiences it. I find your description of "outside the Universe there is nothing" to be an inaccurate way of viewing it, like so many you think of the universe as a definable shape that has boundaries that can be traversed. This is a faulty view, the Universe is the term for the entirety of existence it has no shape and no boundary it's simply the term we use to encompass all that is. So in a way you're right outside the Universe time doesn't exist, because there's no such thing as outside the Universe therefore nothing can exist there.

its mind blowing if you try to break it down and imagine it xD

My thoughts exactly 0.o

time and space are not dimensions determined from equational mathematics. they are experienceable by us, and testable. thus, it is physical reality, even thou i disagree with you on your view of dimensional theories(mathematical determinations using numerical data that is only possible if it conforms and fits with the reality we experience, is still factual data) time can be observed and tested, so can all dimensions of space. its more than possible to determine her question thru scientific method.

Ye I agree with you, the way I said it wasnt right, I was just trying to be simplistic and... um... comprehensible?

Anyway you seem to have thought this through. What say you about black holes? Is it just matter that they absorb? Or do they influence the very nature of things like dimensions?

black holes are just manifestations of our universe. They obey physics and dimensional laws like any other object in it. Hawking even dismantled their legendary status, by showing that they arent indeed bottomless.

I never did understand where science fiction got bottomless or wormhole out of it when a blackhole is simply super dense matter strong enough to absorb light. How anyone got bottomless or wormhole out of that baffles me.

because black holes
prior to hawkings investigation, were never EVER recorded as losing energy. all black holes to that point, were never found to lose energy, only absorb it. hawkings investigation led to the discovery of micro matter being released by black holes.

to put it blunt, black holes were considered perfect dark bodies before that.

well, that is a very rough theory. because he doesntt actually know how long the lifespan of a black hole is. the only way to figure that out would be to find a black hole that was jus created, and follow it for how ever long it takes. now im sure their lifespan is prolly 100's and 100'[s and 100's of years(huge assumption) so itll be extremely difficult to make it a FACT that black hole dont lose energy, but OnLY absorb

what part of "they release micro matter" did you not understand? that is the proof that they lose energy and are not in fact, infinite wells of gravity , because such a body, known in science as a perfect dark body, would never ever lose energy.

to make it simple for you, it would be impossible to register a black hole if they were perfect dark bodies, because those bodies release no temperature or energy. SINCE they do release vestigial amounts of it, they are no longer perfect dark bodies, and hence, not infinite in anyway. they come CLOSE, sure, but coming close in science is still a long way to go.

lolz

I thought so... IF this hypothetic perfect black body was to exist it would be impossible to stop, it would endlessly roam the universe absorbing matter...

1 more thing. Does our sun have the potential to become a red giant? Or just a (dissapointing -.-) red dwarf?

I would imagine traveling to the past would be like going against the flow of time like swimming against a strong a river current and the further you travel back in time the stronger the current gets so it becomes harder or requires more force the further back you travel in time to the past. As for river currents, it is possible to jump in a river and swim against the current until you get out of the river, I have seen someone pull that off with my own eyes. perhaps traveling into the past would be like swiming against a river current, what do you think?
