[QUOTE=Lazor;22596883]hey physics experts
what's some good stuff to read if i want to learn about physics?
i don't really have any prior knowledge about physics but i'm curious[/QUOTE]
dude i've got the perfect book.

You can start by buying some mags on science,They are pretty good and very illustrated.
After that you can start going to the library and buy some books that seems interresting to you
[QUOTE=JohnnyMo1;22596909]Uh, general relativity, dude. Light bends all the time.[/QUOTE]
I guess our entire generation was plagued by poor science teachers.
Sigh.
[QUOTE=Willie Nelson;22596906]I guess so I will read up on those things, I was thinking about learning more before returning back to school so maybe I will be ahead.[/QUOTE]
again pedro the fuzzy has a good understanding of singularities but singularities are not related to wormholes.
[QUOTE=Samoht;22596877]Dude, what if, like, [I]your green[/I] and [I]my green[/I] were, like, different?![/QUOTE]
Fuck off with that shit, it's an entirely new thread. That question is like "does everyone live in there own dimension where our genders are switched but everything is still equal".
You cant go back in time, but the illusion of moving forward in time in a matter of seconds can be done
[QUOTE=billeh!;22596925]again pedro the fuzzy has a good understanding of singularities but singularities are not related to wormholes.[/QUOTE]
Yeah, thanks for the help on that. I get confused between the two all the time.

Duuuuuude.

thanks, i'll check it out sometime this week

well let me recommend a good documentary on space-time for you: it's called 'the known universe'.
im not sure where to find it, but the final episode has an excellent segment on wormholes.
[QUOTE=billeh!;22596664]if someone were to observe someone travelling at a higher speed or in an area where space-time is more compressed than the space-time where observer 1 is at, then time would appear to go slower for the traveler or observer 2.
meaning the faster you go the slower you age and when you're in deep space you age slower than when you're on earth.[/QUOTE]
Other way around. You age 'slower' on Earth than in deep space due to the presence of a gravitational field (which makes time on Earth run slower relative to a place with not as large a gravitational influence).
[QUOTE=billeh!;22596879]well scientists look at wormholes for a prospect of interstellar travel, but a side effect of wormholes, because they are linked through space-time, is that you could wind up in a different time because you're in a different part of space.[/QUOTE]
So you're saying time is just a measurement of where you are in space? Not Space as in Outer Space but just Space.
If you can measure it, what makes you think it wouldn't exist
It's non physical so obviously it's not "real" in the sense that you can see/hear/feel it. But since we use it the ofcourse it exists.
Space doesn't exist yet we gave it a name.
Time is rather just a description for the continuity of consciousness (no not being awake you dumb shit). The shit you want is spacetime, but quantum physics is too young to deduct any accurate theories. Not even string theory answers that :O
Hurp Durp philosophy.
Time as it is commonly known (hours, minutes) are just made up units for measuring time at convenient intervals, but time itself exists. Any observable progression proves the existence of time.

I'm sure I can find it somewhere on internet.

no, the faster you go the 'slower a person ages'.
take a ship traveling at 99.95% the speed of light. if that ship traveled for 20 years around space, when it comes back to earth, earth will be thousands of years into the future relative to when the ship took off.

um dude space exists otherwise we couldn't occupy it...

[QUOTE=Willie Nelson;22597005]So you're saying time is just a measurement of where you are in space? Not Space as in Outer Space but just Space.[/QUOTE]
well, i suppose you can think of it that way
a good analogy is to think of space like a coordinate plane. there are you x, y, and z vectors to identify where you are, then there's the t vector, or time. time is inexorably linked to space.
[QUOTE=wonkadonk;22597038]um dude space exists otherwise we couldn't occupy it...[/QUOTE]
Space is the name for the nothingness that holds everything.

Ah. I thought you meant just drifting in deep space as opposed to being in a spacecraft travelling at relativistic speeds. You'd already covered speed and time, I figured you had moved on to gravitational fields.

no. quantum physics is not young, it's at least 70 years old. time is not a description of continuity for the human mind, time is a thing.

yeah, sorry. im not much of one for grammar or organizing my ideas some days.

Young compared to most sciences, and alot less ''in-depth'' than say, Chemistry, Practical physics etc. TOO MANY QUESTIONS in quantum physics with rather recurring queries that cause more answers and oh fuck I've confused myself.
[QUOTE=TurbisV2;22597048]Space is the name for the nothingness that holds everything.[/QUOTE]
vacuum is an interesting subject. science falters to describe what 'nothing' actually is.
quantum physics, because of its openness to anything, probability wise, dictates that the void is filled with virtual particles that don't 'exist' but borrow energy from the void to 'be' momentarily. they just have to preserve the aspects of the void, such as neutral charge and opposing spins. for example, you could have an proton and a p-bar (the antiparticle of a proton). charge is zero and both particles are opposite of each other.
all of this is very interesting but very abstract, but the physics works out.

actually quantum mechanics can describe space-time very well. it works as well as newton's mathematical equations when describing movements of objects. in fact, it's more accurate than newton.
also, quantum mechanics has revolutionized chemistry, practical physics, and things like that. for example, biology would still be only about observing things as they live, and we wouldn't know about the structure of hemoglobin or ribosomes.
Time is an invention of man. If we believe it exists, it will exist.
It's amazing how real conversations can come out of troll threads here.
All i see in this thread is people arguing theories as fact:/
