Stop doing that. Seriously.
A desperate disease requires a dangerous remedy.

A major source of objection to a free economy is precisely that it gives people what they want instead of what a particular group thinks they ought to want. Underlying most arguments against the free market is a lack of belief in freedom itself.

Time and space are relative to your own time and space (and speed and mass). When you put them all together (motion, time, mass, velocity) they all change in a predictable manner. Einstein predicted this many years ago but until recently the predictions haven't been able to be tested.
NASA is starting to test some of the predictions.

oh yeah, i remember now [http://forums.massassi.net/html/smile.gif] i disagree with most of that theory. i think that time is an absolute. there is one present, one past, and one future. we are always moving from the present to the future and away from the past. space, on the other hand, could be subjective because i believe that the universe is infinite. therefore, locations only have meaning relative to the observer.

[edit: where did they say they figured out that time could be changed or whatever by a planet, black hole, big cow, etc.? i like this kind of thing ]

In his theory of General Relativity, Einstein predicted that the three dimensions of space and time form a four dimensional reality.. Massive objects, the theory says, warp and alter space and time around them.

gamma = 1/sqrt(1-beta^2) where beta = v^2/c^2

Time dialation t'=gamma*t where t is the proper time
Length contraction: L'=L/gamma where L is the proper length

Rest energy (gamma=1): E=mc^2
Kinetic energy: K=mc^2(gamma-1)

I believe in a separate past/present/future, but I think the perception of when it all occurs is altered by relativity.

I thought the idea that from the perception of a galaxy lightyears away moving in my direction (or away, I forget) what I'm about to do happened a long time ago, negated the idea of free will, but there is really no connection between a will existing to perform an action and when the action is percieved.

We have intertwined the idea of free will with the notion of linear time, so much so that when linear time is disproven, we question free will.

They proved that time is not definite but can warped at great speeds by placing an atomic clock on a jet and flying some large distance. Comparing it to a control clock, they differed by the exact number of nanoseconds Einstein predicted.

No, it doesn't. What it means is that we're witnessing events that have already taken place, not events that are going to take place. Looking deeper into the universe isn't prescience; it's looking into the past, and seeing past events.

It took 15-30 minutes for the impacts of Comet Shoemaker-Levy 9 hitting Jupiter before we saw them. Supernova 1987A occurred 168,000 years before we saw it.

...Because everything we see is dependant on the speed of light. Even when you move your hand in front of your face, there is a delay between when you actually did that and the time it took you to see it (of course, then you have to take into consideration that your brain had to process and assemble the data). Now, the delay is so small, it's unnoticeable because the distance is so short. It's easier to see the delay over longer distances, however, such as in the above examples given by firefox.

However, firefox seems to be forgetting the twin paradox and Einstein's second postulate to relativity, which are both rather 'time manipulative.'

*All of this, of course, is according to modern physics theology.

Relativity and Quantum Mechanics is really cool (and really hard) stuff when you get to study it in College. Turns out, Newton was wrong about many of this theories concerning physics... although his mistakes dont become apparent or important enough to consider until you either get objects moving at velocities close to the speed of light, or objects that are extremely small (protons, electrons, neutrons, and smaller). In fact, using Uncertainty Principles, scientists have found ways to violate Energy Conservation.

And I was referring to your comment only pertaining to Eistein's first postulate. Your comment had absolutely nothing to do with Eistein's second postulate...which is what I was pointing out as it pertained to the portion of BH post in which you quoted.

Can you tell me more about this?

Also, you don't do any Quantum Physics before University? You're totally missing out, we have to do at least two modules on Quantum Physics, involving the photoelectric effect and particle-wave duality; it's fantastic, although I totally disagree with you when you say it is hard. I think everything makes much more sense when you try to explain it in terms of fundemental particles, and it's one of the reasons I possibly want to study theoretical physics at Uni.

But anyway, can you elaborate on violaing Energy Conservation?

I haven't learned a lot about it yet, but from what I've heard if I and a peron in a galaxy lighyears away were to take a snapshot of all the events occuring at this moment in the universe, we wouldn't be taking a picture of the same moment, because of relative time.

His point in the universe is on a different moment than mine is, and therefore from his perspective an action I'm about to perform already occured in a snapshot he took several moments ago. I wasn't talking about an actual person's perception of a far-off event altered by the speed of light at which it travels, I'm talking about the actual bends in time that occur on the edges of black holes or quickly moving galaxies. Again, I know very little about.
