I have a ton more of facts about the preceding. I just thought I would share some.


BTW, this can also be found in the late night OT thread


Im pretty bored.

She kept her motor clean
She was the best damn woman I had ever seen
She had the sightless eyes
Telling me no lies
Knockin' me out with those American thighs
Taking more than her share
Had me fighting for air
She told me to come but I was already there
'Cause the walls start shaking
The earth was quaking
My mind was aching
And we were making it and you -
Shook me all night long
You shook me alll night long

Another interesting book is 'HyperSpace'. If you liked Hawking's book, you'll probably like this.

wait a minute its not intirally impossible to go back in time\ create a time maching. What if you inverted your speed, so instead of going 2,000,000 mph, you go -2,000,000. there is perfect logical reasoning there.

Well, theoreticaly, if you shoot an orbit between two closely orbiting neutron stars you could come out before you entered, due to space-time curvature doing wonky things to an event horizon.

bah!!
this sounds like yet another layman's version of a very complicated theory dumbified for everyone with half truthes and misinformation.

Why doesn't anyone ever do a college report on Revelations? Man I could tear up a paper writtin about Revelation. Like the seven churches, the rapture, tribulation, anti-christ....and on, and on, and on, and on..and right when you think I"m done..I just keep going and going and going

[mykroft]

Phyre: Complicated theory, simple implementation, only the causality is brain-bending, I definitly waved a dead chicken over the cause, but the effect theoretically should be simple. I'm no serious physicist, but my knowledge is beyond the average layman (hey I find physics interesting!).

JesusFreak; Been there, done that, yeah, it was definitely interesting.

Well, actually, there is gravity in space. For example, in an orbit, you are still under the influence of Earth's gravitational field, but you are in a state of continuous free fall. This is why orbits decay (i.e., Mir). Also, there is time in space, since time and space exist in an interwoven four dimensional continuum. While it is impossible to go back in time by going faster than lightspeed (unless you are massless of course ), singularities, wormholes, etc., do make this possible ecause of their intense gravitation. Gravitaion is the result of mass bending space toward itself, and since time and space are intimately related...well, you get the picture. And the superluminal propagation experiment with the cesium gas did not violate Einstein's theories because light is massless. Only objects with mass increase in mass exponentially as they approach lightspeed.

Want something that'll really bake your noodle? An Australian astronomer has proposed that the speed of light is slowing down uniformly. I.e., light traveled faster in the past than it does in the present.

Lord Vader:

Are you saying that light produced today is slower than light produced a year ago, or that light slows down, just as a car slows down when it is coasting? I would like to read about this australian guy as well, so please post the link or place you found this information from.

lol, I just finished the 7th.

About the light slowing down over time, since light is massless, would there be any effects of friction? And where can I find out about this aussie guy.

Lord Vader: orbit's such as Mir's decay through friction, in Mir's case it's with the earth's atmosphere. Vacuum isn't. There are always particles in space. You hit the while in orbit, and slow down a fraction, this adds up and your orbit drops. There is no gravity per se in space, there also isn't on earth, you are affected by a gravitic field, which pulls you towards it's centre, on earth, and out to cis-lunar space, the earth's gravitic field is overpowering enough that you don't feel the effect of the Sun's or Jupiters for example. no matter where you are, you are affected by many gravitic fields, some of which actually are stong enough to really feel the effects.

Tachyons. I've heard of those, I don't know much about them though. Yeah, I was mistaken about the space time and gravity thing, It was 1:30 in the morning.

BTW, there is a game out, "Tachyon: The Fringe" That game rocks

Right, but my point is that outer space is not devoid of gravity. However, if you just went straight up, even outside Earth's atmosphere, you'd come right back down unless you place yourself in a precise path that uses the Earth's pull to keep you moving away from the center of the Earth (i.e., an orbit). In fact, you are technically under the influence of stars' gravities from the other side of the universe, since the force of gravity tends to zero as the distance between the two objects in question goes to infinity (according to Newton's Law of Universal Gravitation).

As for the Australian guy, I'll post some references after I get home from work; it is in a book I have that details evidences for the case of special creation of the universe. From what I can tell, he proposes that the speed of light basically has not always been 300,000 km/s. Yet, it seems constant because 1) we have only been abe to accurately measure the speed of light for the past half century or so, and 2) all light travels at the same speed (i.e., light at any given point in space travels the same speed as light from any other given point, yet that speed may be decreasing uniformly).

Hey Tom, thanks for the simplification of what I said. I can get verbose sometimes. By the way, I am an 18-year-old rising sophomore at Georgia Tech majring in nuclear/radiologial engineering, in case any of you were curious as to my educational background.
