wanna place a bet on that??

9 foot long garage, 9 foot ceiling, park a 12 foot car in there, all 4 tires must be firmly resting on solid object under the cars weight.

A^2 + B^2 = C^2

Better yet, 9x9x9 garage, what is the longest 2"x2" single piece of lumber you can fit in there?

Wank.a.lot

---- i was thinking of taking the 12 foot car going about 100mph into the wall of the garage would shorten it a few feet and then it would fit.

actually im pretty sure that is wrong, light can only go a certian speed no matter what, shining a light while moving doesn't add your speed+lightspeed
at least thats the way i understand it

b18.

Light moves at a constant rate unless matter interferes with it, but relatively it would be slower, i.e. Bone knows what he's talking about.

Einstein stated that faster than light travel couldn't work so long as causality was maintained, i.e. you can send faster than light signals because consequently they could be sent back in time, like the tachyonic antitelephone, and there is no such thing as a free lunch in time travel.

The main reason would be that by the Lorentz factor the speed of light is a denominating factor in the equation, wherein you'd have the integrated equation = infinity as it approaches the speed of light and you can't have an infinite force, it's not a real number.

What he said.

But the neat thing is that things without mass can accelerate faster than the speed of light, they've made electromagnetic ray guns that shoot signals faster than the speed of visible light in a vacuum.

Pretty neat.

Speed is relative, how fast are you moving now?

RELATIVE to what?

A golf ball could destroy the earth at light speed. By the way, Mista bone, you're wrong. Speed of light is the same for everyone, even if he go at 200 000 m/s. It's the first postulate of relativity!

I find a good website about relativity:

m = gamma * mo where mo is rest mass... and gamma is 1 / sqrt(1 - v2/c2)

So your gamma is a modification factor of sorts... the faster you go the larger gamma is. Gamma is pretty much 1 until about .9c... 90% of the speed of light. Basically the theoretical practical max v is right before gamma exponentially increases.

My suggestion... take a modern physics class for fun. Things can move faster than c though... like oscilliscope traces for instance. The particles hitting the screen themselves don't move faster than c, but the beam moving across the screen can. Think of a lighthouse spinning around and around. The light it puts out moves slightly slower than c because of the non-vacuum. However (R * theta) / sec (radians per sec) can be many times faster than c, so the leading edge of the beam of light can be circulating faster than a beam of light projected and then bent in a circle would. That's just something neat to think about.

Btw if you delve deeply into physics and actually think about what you're studying you'll begin to doubt reality and existence... and I'm not even joking.

I'm not a physics person, but like other people said even in a vacume according to einstein matter and energy are related. As you increase the speed of something close to the speed of light it begins to gain an exponential amount of mass, due to the energy that it takes to get it moving that fast. As the mass increases the energy it takes to acclerate it further also increases. To the point where if anything with mass was acclerated to the speed of light it would obtain an infinite mass, hence requiring an infinite amount of energy to put it at that speed, and infinite energy is not possible, so the speed of light is not possible for anything with mass.
