hello, I've always been wondering why do people say that nothing can travel faster than light? is it because we just don't have anything to push to a speed faster than light or is it actually impossible??
You can apply a force to an object forever and it will never reach the speed of light.Riko said:What do you mean by that statement?

Jeff B said:light... It's the visible part of the electromagnetic spectrium
Riko said:so right now we could change energy to mass but not mass to energy? i always thought that all physical changes could be reversed but this is the only thing that i came across that can't be done. that sort of bothers me a bit :grumpy:
Phobos said:We can change mass to energy...like Amphi said. Another example...fission bombs.
chroot said:According to currently accepted scientific theory, it is impossible for anything with mass to go the speed of light, and anything without mass to go any speed other than the speed of light. It has nothing to do with our technology.

hemmul said:I remember that, actually, Einstein's theory was saying that it is impossible to accelerate a massive body up to speed of light, however it says nothing about the objects already moving faster than light - e.i. such objects can exsist. Is it "accepted" in current theory?
Chronos said:atomic clocks traveling at the same speed but in opposite directions relative the the rotation of the Earth do not tick at the same rate! this is easily explained by LR. it is possible to explain by GR, but is very complicated.
swansont said:What's so complicated about it? All you have to do is use an inertial observer as a comparison point for all of the clocks, as was done by Hafele and Keating (Science 177, IIRC).
I'm no expert on atomic bombs so I'm not entirely sure, however I believe some of the mass is converted into energy. The point is, matter CAN be turned into energy and energy can be turned into matter. Why? They're the same thing!Riko said:I thought that just turns the bonds between protons and neutrons to energy?
The speed of light, denoted by the symbol c, is approximately 299,792,458 meters per second in a vacuum. This is the fastest possible speed at which energy, information, and matter can travel.
According to Einstein's theory of relativity, the speed of light is a fundamental constant of the universe. This means that it is impossible for anything with mass to travel at the speed of light or faster, as it would require an infinite amount of energy.
No, there are no known exceptions to the speed of light being the maximum speed in the universe. Even particles that are thought to travel at or near the speed of light, such as photons, have mass and therefore cannot exceed the speed of light.
Time dilation is a phenomenon that occurs when an object is moving at speeds close to the speed of light. This means that time will appear to slow down for the moving object relative to an observer who is at rest. This is due to the fact that as an object approaches the speed of light, its mass increases and it requires more energy to continue accelerating.
Currently, there is no known way to travel faster than light. Some theories, such as wormholes and warp drives, have been proposed, but they are purely speculative and have not been proven to be possible. The laws of physics as we know them do not allow for anything to exceed the speed of light.
