i read from somewhere reliable that lightspeed is considered the fastest speed and you cant exceed it . i think its said by einstein or smething.

why is it so ? just becos currently it appears to be the fastest speed?

ohh ... btw the guy who say light has no mass. if that hold true , den why does black hole still bend light when they are near them?

You can not move faster than light because the material in your body is made up of the same material as light.

The light particles in your body is very small and numerous. The collection of their individual movements is what others see as your body.

To move at the speed of light all you need do is get ALL the parts of your body (I mean every sub-atomic particle) to move in the same direction at he same time. You need not do this for long either. At 3x10^8meters per second you would be well off planet earth during the time it takes to say "go".

Any parts that did not go with you would end up on the floor for you to clean up if you get back.

Take a rocket? Same problem. The particles that make up any fuel are made of light but not all moving in the same direction. Their random motion limits your ability to reach light speed.

On the bright side light particles moving at light speed got up to light speed from very powerful but local interactions. Currently we think the speed of local light may have been the result of our local Galactic Core or our local Big Bang episode. Other Big Bangs at other times and or other places in the Universe may cause their material to move at higher or lower local speeds of light in their time and locality.

Yes there may be things moving faster than light we have not detected yet. Our tools would have to be tricks to notice anything moving faster than light because the tools themselves are made up of material made up of light. Much easier to catch things moving slower than yourself.

You are right. Einstein theorized nothing can travel faster than the speed of light, c. It's a consequence of his theory of General Relativity.

Of course, let's remember the nature of Science. It's subject to revision as new evidence surfaces. As new theories, capable of explaining the universe better, are created, others are replaced. We don't know that the speed of light is the fastest you can go. All we know is,current evidence points to it.

Of course, the burden of proof is on those claiming new findings, or proposing adjustments to theories - or new theories altogether. The title of scientist or professor, or any other title is utterly meaningless in science. Authority is never, in itself, a substitute for evidence.

As Carl Sagan once said, big claims require big evidence. Appeal to authority has no place in science. What facts do you have? Can the results of your experiments be reproduced and verified by the scientific community? Have your results been published so they can be verified? Are there other scientific experiments corroborating your findings? Is it possible to interpret the results in an alternative, simpler way, one not requiring major adjustment to an established theory? Occam's razor has a big place in science.

From what we can from the science of the last 100 years, it looks like time and space are related. We used to think that moving in space had no effect on time, and vice versa. But now we know that they are related in such a way that, when you move forward in space by 186,000 miles, you also must move forward in time by at least 1 second. You can think of "c" (the speed of light) as being the constant that relates space and time in our universe.

What happens if you're almost at the speed of light, and you try to go faster? It turns out that time slows virtually to a standstill, so you'll have a hard time pushing on the accelerator. Also, your inertia starts growing infinitely high, so it requires an infinite amount of force and energy to push you any faster.

The fastest bits of matter on earth are microscopic particles that we run though particle accelerators. We continually pump energy into them to get them to go as fast as we can. We've gotten them to go at 99.999% of the speed of light; but at those speeds their inertia (resistance to change) goes way up, so that even if you pump 100 times as much energy into them, it's still not enough to push them past that limit.

the reasoning is that the swifter you commute the extra mass you have and as you recommendations-set the fee of sunshine your mass turns into infinate making it impossible to commute any swifter. that's all theoretical and can't be shown or disapproved. gentle travels in a wave Waves commute via a medium only as a valid wave can in trouble-free terms commute at a undeniable fee because of fact the skill can not propagate any swifter gentle waves can not probagate any swifter via area than that speed ( 186,000 miles in keeping with 2nd.

Gamma or X-ray exceeds light in velocity: new find

Though Einstein's equation sets higher limit to the speed, but there are some exceptions. For example, Cerenkov effect describes blue light is emitted when electron goes faster than light in any transparent medium .

I have shown gamma or X-ray exceeds light in velocity. Shorter wavelength of gamma or X-ray than that of light allows deeper penetration into denser materials like lead. For example, smaller size allows jet fighter to go faster than passenger plane. My research into fundamental physics of electron and photon unfolded the fact that photon is also a wave in the shape of an inverted Y. Therefore, wavelength or photon size of gamma or X-ray is smaller than that of light. But size alone is not enough to explain its deeper penetration into lead. Higher energy boosts the speed of gamma or X-ray photon to exceed that of light photon so as to allow deeper penetration into lead.

Light has no mass and therefore no friction and can go as fast as possible without anything to slow it down.
We have mass and therefore friction will slow us down and we can't pass light.
