Faster Than Light?

[dre]

aren't we, by just being, all traveling through time?



Here's a question about infinity:

From high school math, I was taught that there are an infinite number of points between any two given points.
(remember, a point is a dimensionless geometric object having no properties except location)

This being assumed, you would then have to touch an infinite number of points in order to travel the distance between the two points. If you had to touch an infinite number of points from point one to point two, how could you ever reach the second point?

[Porsche]

You couldn't, but that's stating the obvious.

[dre]

but we go from point to point all the time.
From home to work, is point A to point B.
but, we shouldn't be able to make it to work (B), right?

Or, maybe we have to be aware of this, for it to affect us.
(Sort of like the Coyote doesn't fall till he realizes he is off the side of a cliff.)
So, if you are at work now, you can never get home!
Oh No!...don't read this until you get home.

...but even though there are an infinite number of distances to travel, each of those distances are infinitesimally small. This makes them cancel each other out.

Let's say you had to travel one meter.
Thats:
1 * 1m
10 * .1m
100 * .01m
1000 * .001m
1000000 * .000001m
ad infinitum...

Actually there has already been a light accellerator made. A physicist has found a chemical that actually speeds up light as it travels through it...

He took two beams of light...
Beam 1 was sent through air.
Beam 2 was sent through the chemica.

Beam 2 reached the target before beam 1 did.....

Sorry I don't remember all the details, it was about a year ago that this was done.

[Lizard King]

I remember that, I made a topic about it on another board. I don't think it counts as truely breaking the speed of light. I'm not sure though...

[Racer 20]

It's simple. The velocities that space/the universe is expanding at are faster than the speed of light. It's in a National Geographic. I'll try to find the issue later today and share it will all of you.

[kris]

What happens if you are cruising through space, at the speed of light, and you turn your headlights on?

[G-Forces]

Come on guys everyone knows that this was solved in Star Trek years ago. It's call Warp! Geez.

Also anyone whos watched Superman knows that if you fly around the world fast enough and make it spin the other way you can reverse the effects of time! You guys think you're all so smart!

The rebirth of a 5 month old thread. Time warp.

Relativity does not say nothing can travel faster than light. It is simply a conclusion from the function of the total energy of a mass that no mass can be accelerated above the speed of light. To be accelerated that fast would require (not infinite energy, like some think, but) more than infinite energy.

But there might be some as-of-yett-undiscovered way of getting past the barrier, jumping past the lightspeed without passing the energy mountain, cause on the other side the function flattens out again, and the total energy lessens the faster you go. This of course would render normal chemical bonds, and plenty of other principles our bodies relies on, effectless to the automatic acceleration that proceeds, not to mention that we'd be turned to plasma (if you can even call it that) by the energy released in this tachyonic state.

[TheMan5952]

yea, I think that eventually humans will find a way to break the light barrier as we did the sound barrier.

How about this one. The speed of light is slowing down. From what I've read its by one billionth of a second every one or two years.

seconds are not a measure of speed.

[AEstud]

the speed of light is not 186,000 miles per hour its hours pers second. If you don't believe me look it up.
