Light is fast. Fast is light. I like to light fast east and light.
.......
Senseless was the above, but alas, my topic this day is light, and my disagreement with the thought that it's speed cannot be surpassed. I don't even quite understand how people come to that conclusion. The reasons..... Are just odd.
One, time gets screwy as you go faster. If you look at something going really fast, the time is somewhat off with it to you. I can believe this, because I'm very fond of the use of illusion.
Fact is, light always moves relative to what shot it off. If you're moving at the speed of light, light will be going faster than you in the direction you're going. At the same time, the light coming off your rear won't be moving at all.
Thus something moving away at high speeds will seem to be effected by time differently, because the light takes longer to get to you. Things that play with light to give off falsehoods I deem as illusion, so the time discrepancy and eventual disappearance of something moving fast is.....
An illusion.
Second reason against it is...... Just kind of odd, and less sensible.
"Things moving fast have increased mass."
It's a relative line, apparently. Somehow, it got applied to light speed to claim that something will have an infinite mass when it's moving at the speed of light.
Which would imply that every particle of light would destroy the universe. Infinite mass means infinite gravitational force, which will cause infinite acceleration if there's a distance that happens to be less than infinity.
That makes no sense whatsoever.
Instead, I think that the quote is.... More of a misquote. It'd make more sense to me if it was.
"Things moving fast when compared to you take more force to accelerate."
Which is undeniable. For one reason. You first have to accelerate so that the force exerted upon the object wouldn't be negative, and then place that much more force to accelerate it further.
For example, a child on a swing with 'er pops. He's the type who loves to go all out, so he'll push with the same force every time. The first push will undeniably be the most significant. Second will have a diminished effect. And, eventually, he'll be pushing full force to keep his kid at one height.
It's not because the kid's heavier. It's because he has to accelerate his arms with a good portion of the force he's putting in so that he can apply force to the swing.
The implication from this is that it would be a pain in the arse to make something go away when it's already going. It would take quite a few tonnes of force to push something past the speed of light from earth.
However, if the thing was exerting force upon itself, such as a rocket with engines, the force required to accelerate further would not increase.
Thus as long as something can accelerate itself, there's no problem surpassing the speed of light.
Unfortunately, things have difficulty accelerating themselves. Cars use friction that they shares with the earth. Planes use their interaction with the air. In space, such acceleration is far from simple, as things only have themselves. But difficult and impossible are two completely different things.
