Turning back time

Re: Turning back time

You have to think, what if we are already living in a black hole?

We would never know, we've never seen what's inside one of them nor do we completely understand it's properties.

What we haven't seen does not exist.

Re: Turning back time

Electrons are time independant? You mean they lack mass of any kind? They must have mass since they exist... Anyway, if something is time independant, then you can't really say that it is impossible to travel faster than TIME.

Um, we would know, trust me.


As for going faster then light to reach time travel to the past is true... but not in the ways you put it.
Say we traveled to Planet X at 3x the speed of light. If we looked up we would see us traveling backwards to planet earth - or the past. Although we can see the past as it is going to reverse, we can not change the past, if we tried to go back to change the past, it would just be present.
Confusing, no?

Time travel to the future = impossible.
Stopping time = possible, but we would just need infinite energy... :P

Re: Turning back time

I've decided that since speed is relative to time, if you can somehow achieve negative speed, you can go back in time.

We would be dead.

We don't need to see one from the inside to know what would be inside of one. Black holes are just extreme gravitational distortions. There would be all kinds of heat and trapped light energy inside the event horizon. However, you're never going to get that far anyway.

I concur with Reach. Nothing Escapes the gravity of a black hole. Anything that comes near is streched and then ripped into nothingness. All mass is compressed into particles. Nothing will escape, and nothing lives.

Re: Turning back time

Reach, how can you confirm that?

We can theorize all these things, such as what is a wormhole, blackhole, or even an electron and what do the do. But we can't say they are concrete facts. However, because we see things the way we see, we can say that blackholes do exist and a blackhole does have a high level of gravity pull, one that smashes everything together in a very, very, dense mass. We can also say that dragons exist, but do they?

I mean, as far as I know, electrons do not exist, yet, we know they are there.

Methinks that your talking a wee bit of rubbish.

"We can also say that dragons exist, but do they?"

No...

"However, because we see things the way we see, we can say that blackholes do exist and a blackhole does have a high level of gravity pull, one that smashes everything together in a very, very, dense mass"

Yep...

Sorry I was wrong, your actually talking perfect sense

Re: Turning back time

Praytell, how does the First Law disprove any theory of time travel?

If I could send myself into the past and meet myself, I've created energy, breaking the first law of thermodynamics.

I didn't change the energy from one state to another; at that time period that I traveled back to, the energy was never used. It's still there in its original form. I just popped out of nowhere. For that interval of in between where the object was sent to and until the object is sent back, there's new energy. That's, of course, given nothing interferes and creates a paradox.

Granted, now that I think about it, if you look at time as a field, like the "4th dimension," or something, then you can dismiss that, I guess. But that would mean for every interval of time, there's energy just for that time period, and it's all equally distributed over this "4th dimension," until someone or something time travels.

It's pretty much just circular logic.

I asked the dragon question to prove my point. Pretty much everyone in general can agree they don't, but that's the same thing with the black hole concept. If we can get everyone to say something exists on the basis of only some facts that may not be true, then it'll exist. If everyone says it doesn't exist, then it doesn't exist.

No, we're not in the middle of a black hole.
And if you're saying black holes only exist because of "unprovable facts," you're wrong. We've seen black holes.


Get over it.
And if we were truly in a black hole, we would all be dead now.

Re: Turning back time

But existence is such a fickle thing. What is stopping us from saying that all that is happening is but an imagination?

We've seen blackholes, but not inside them.

~Tsugomaru

[Idonnoimconfused]

Re: Turning back time

We can not prove whether or not we live in an imagination, or if anyone around us is TRULY alive.
But, that has nothing to do with this topic.

Anyway - if we were inside a black hole, where would the jet streams be? They can't just disappear.

So assuming we're in a black hole, all the observations of the "universe" that the Earth is in are false? There have been calculations that show that the "universe" is expanding, (cited from "The Universe at Midnight"), so assuming we are in a black hole, the black hole is expanding. However, why is no new matter appearing in the black hole then? Even though light allows us to see one light-year farther every year, shouldn't a black hole cause irregularities in the movement of celestial bodies, so wouldn't we seem something erratic, not like comets (which can have a parabolic, elliptical, or hyperbolic orbits), but something like a comet with a random walk. Therefore, we can't be in a black hole because we aren't being distorted to the point of destruction.

Some more food for thought, if we are in a black hole (which we probably aren't), why is omega less than 1? (cited from "The Universe at Midnight") If in theory, we are in a black hole, then more mass should be swept into the black hole. Therefore, assuming the black hole stays the same size, omega should increase. However, it is decreasing. Therefore, the "black hole" is expanding, which can't be correct if more mass is being swept inside. The expansion should slow down, but it is speeding up. (Also cited from "The Universe at Midnight"). Why is the expansion of our "universe" speeding up if our "universe" is a black hole?

Re: Turning back time

Dont want to burst anyones bubble but black holes are just a theory.
Oh wait, yes i do. Im just a bitch.
