What is the mass of a body if it travels speed of light?
Since the electron has 'rest mass', there's not enough energy in the universe toboost one to light speed. With enough energy, you can push an electron as closeas you want to light speed, but it can never get exactly there. At light speed, themass of an electron would be infinite.
What is the speed of an electron traveling at 80 percent the speed of light?
The speed of light is approximately 3 x 10^8 m/s. Therefore, 80 percent of the speed of light is 0.8 x 3 x 10^8 = 2.4 x 10^8 m/s. This would be the speed of the electron traveling at 80 percent the speed of light.
How much energy does it take a spaceship to travel at constant speed 90 percent of light speed?
The energy required for a spaceship to travel at 90 percent of the speed of light would be substantial due to the relativistic increase in kinetic energy as speed approaches the speed of light. The energy required can be calculated using Einstein's mass-energy equivalence formula, E=mc^2. The exact amount of energy would depend on the mass of the spaceship and would be calculated as the difference in energy between its rest mass and its kinetic energy at that speed.
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".
If something has low mass would it take less energy to get it to light speed?
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.
Why you cannot accelerate electrons greater than the velocity of light in free space?
According to the theory of special relativity, it would require an infinite amount of energy to accelerate an electron to the speed of light in free space. As the electron's speed approaches the speed of light, its mass increases, making it harder to accelerate further. Moreover, at the speed of light, the electron's energy would also become infinite, which is not physically possible.
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.
Where does all light originate?
Light is a visual manifestation of energy; resonation of particles at very high frequencies. Mass can become energy and energy can become mass, according to Einstein's relativity theorem. Imagine two substantial masses colliding at high speed. This would release enough energy to produce visible ligt.
What is the speed of an electron traveling at 80 percent the speed of light?
The speed of light is approximately 3 x 10^8 m/s. Therefore, 80 percent of the speed of light is 0.8 x 3 x 10^8 = 2.4 x 10^8 m/s. This would be the speed of the electron traveling at 80 percent the speed of light.

Does matter turn into light when achieving the speed of light?
No, matter does not turn into light when achieving the speed of light. As an object with mass accelerates towards the speed of light, its energy increases, but it does not transform into light. It would require an infinite amount of energy to accelerate an object with mass to the speed of light.
What would happen if a car could travel at the speed of light?
It would turn to energy
Is the speed of light the highest speed possible?
Yes, according to our current understanding of physics, the speed of light in a vacuum is the fastest speed at which energy, matter, and information can travel. Any object with mass that approaches the speed of light would require an infinite amount of energy to accelerate further.
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
