If something has low mass would it take less energy to get it to light speed?
Dipit
As much as we've tried, no one's yet found a loophole in the equations. Regardless of its rest mass, pushing a chunk of matter to the speed of light would result in its acquiring infinite mass, and thus requiring an infinite amount of energy to put it "over the top."
Einstein may not have said it in so many words, but the short answer is, "You can't get there from here" -- if you took all the energy in the observable universe, rounded it up into the biggest laser ever and pointed it at a single electron, you couldn't push that electron to the speed of light. Ever.

Would Light protons stop you if you were going at the speed of light?
No - you would be stopped BEFORE you reach the speed of light, by your increasing mass (among other things). As your speed approaches the speed of light, your mass would approach infinity, and it would require an infinite energy to actually achieve the speed of light.Note that the "speed of light" is not really about light. It is a speed limit of our Universe; some have described it as the "speed of causality".
What determines the frequency of electromagnetic waves?
An EM wave is caused by an energy source, such as something as big as a supernova or something as small as an electron changing in speed. I would say the change in the energy level of the energetic particle that causes the wave determines the frequency of the wave. +++ Whilst you may be right about the quantum physics, the frequency of the wave is that of the energy source, be it in a star or a radio transmitter, driving it.
What happens if 2 protons collide at the speed of light?
The short answer is: they can't. Protons, or any other particle that has mass, can't go at the speed of light because it would take infinite energy to get it going that fast. In particle accelerators, they make protons collide at a speed very slightly less than the speed of light, something like 99.99% of the speed of light. It takes a lot of energy to get the protons going that fast, and all of that energy is released in the collision, hopefully making some interesting results.
Are nao seconds faster than the speed of light?
No. It's not possible to go faster than the speed of light. The speed of light takes all the energy in the universe and if you somehow did manage to get going that fast you would cease to exist.
When you add energy to matter the particles move faster?
Thermal energy is heat. When something gets hotter the atoms that compose that object vibrate or "wave" at a higher frequency. However, if you shoot a particle through a particle accelorator, the thermal energy of that object is not relevant to the kinetic energy (or speed/momentum) of that object. As an example, if one had the ability to heat up a light particle, it would have higher thermal energy and would therefore "wave" at a higher frequency. But the speed of light would remain constant as it always does.
Can anybody run at speed of light?
No, a person can not run at the speed of light. To make something move faster and faster you need more and more energy, and the more mass it has, even more energy it needs to move. The reason why light can travel at its own speed is because it has no mass, and it would take an infinite amount of energy to make something with even the slightest amount of mass to make something move at the speed of light.
Why can satellites not attain the speed of light notwithstanding they are in absolute vacuum?
As the speed of an object approaches the speed of light, its kinetic energy approaches infinity. An object moving at the speed of light would require inifinite kinetic energy.

What would happen if a car could travel at the speed of light?
It would turn to energy
Are there such things as time mashines?
No, a time machine would require you to travel faster than the speed of light, which would cause you to turn into pure energy. If scientists found a way to make something travel at this speed, it would not last long.
How do you travel as fast as the speed of light?
you do not; it would take way too much energy to do this because your mass is so great. Small subatomic particles can be accelerated to close to he speed of light and they require a lot of energy from a particle accelerator. Nothing can reach the speed of light as it would take an infinite amount of energy
What does the funny formula the Einstein made up mean?
energy=mass times speed of light squared (times by itself) (e=energy m=mass c=speed of light) *This formula calculates the energy that an object can release when its atoms are split (Same process used in atomic bombs). The formula means Energy is equal to mass times the speed of light times the speed of light again. In other words energy = mass x speed of light x speed of light. In numbers it would be energy = mass x 299'792.456 x 299'792.456 (Speed of light = 299'792.456 km/s)*
How much energy you would produce if you were going the speed of light?
Since no object with mass can reach the speed of light -- such an object can only approach that speed -- the question is meaningless.
What determines the frequency of electromagnetic waves?

Why Lorentz Tranformation does not allow any object to reach the speed of light?
from a purely mathematical stand point, if something were to reach the speed of light the time dialation/length contraction formula would yield something over 0. This is beacuse the formula is: constant/[(1-(velocity/speed of light)^2] as you can see, if velocity=speed of light, you get something over zero.
If a body were accelerating at a rate making its mass equal to its normal mass on earth how long would it need to travel before reaching light speed?
It would take infinitely long in both time and space, and require and infinite amount of energy to accelerate any object with mass to the speed of light. In other words, it is impossible to reach the speed of light. Einstein's equations show that as an object approaches the speed of light, it's kinetic energy is converted to mass making it heavier and heavier, require more force and energy to accelerate it. As a result at 99.999999% the speed of light the object would be come so massive that it would require more energy than the universe contains to push it fast enough to be going the speed of light.
