Why can there can be no speed greater than the speed of light?

Question

Light travels with a tremendous speed, the greatest speed there is. We cannot invent any rocket which moves faster than light, Why?

Answer 1

Light travels with a tremendous speed, the greatest speed there is. Anything traveling at that speed will turn into light. The heat of that speed is such that anything at that speed will become light. So there can be no speed greater than the speed of light. We cannot invent any rocket which moves faster than light, because then it will turn into light itself, immediately it reaches the speed of light.

Answer 2

Light travels as mass-less photons that are tiny packets of energy. Photons carrying different amounts of energy all travel at the speed of light but with different wavelengths. Because photons are pure energy and adding energy will only change the wavelength there is no way to make them go faster. However, a rocket includes mass and can not reach the speed of light unless an infinite amount of energy is added (which of course is impossible). If a rocket was traveling slightly less than the speed of light, the only way to add to its velocity would be to throw out photons in the reverse direction or to reflect photons off a mirror on its tail end. That would be like speeding up a car going 29.9999.... miles per hour by striking it from behind with tennis balls traveling at 30.0000... miles per hour. As the car gets nearer and nearer to 30.000... miles per hour each tennis ball imparts less and less energy from its 'bounce.'

Answer 3

No material body can ever travel at c.

The reason is that c is a constant to all observers. Consider a light flash passing you by. You try to run faster and faster to catch up with it, but no matter how fast you run, the light flash still passes you at a speed you measure as being c. You can never catch up to it, or even hold your distance from it. It will always be receding from you at c.

To a stationary observer watching all of this, since the light flash ahead of you is increasing in distance from you, and it is traveling at speed c, you must be running at less than c no matter how fast you run.

Answer 4

well lets see... a rocket could prolly go around 50,000 mph(assuming high) but LIGHT travels at 669,600,000 mph. That that will be quite the jump. I dont think the material man has can withstand the tension that will be created when going that fast. but going that fast is unrealistic.. i think o.0

Answer 5

This is only a theory, resulting from the fact that supposed academics like to talk at great length and with great certainty about things which they know nothing about.
