how does the wavelength of a speeding object with any mass prevent it from attaining the speed of light?

Question

or in other words: why can't humans travel the speed of light and what does it have to do with the wavelength of a speeding object increasing with increasing speed?

Answer 1

It has nothing to do with the wavelength. Although every mass has an equivalent wavelength (given by using Planck's constant), it is special relativity which rules here. As a mass approaches the speed of light, its mass increases, rendering it more and more difficult to accelerate further. An example of this is the SLAC machine at Stanford, which can kick an electron to 90% of the speed of light in just a few feet, but continues to kick the electron in the tail for another two miles. Almost all of the energy shows up as increased mass -- increasing it by a factor of over 40,000.

Answer 2

The wave length of an object does not make sense to me in this situation.
The mass of an object that is accelerated increases. As the speed approaches the speed of light the mass increases without bound. Einsteins famous equation E=MC^2 describes how much energy is needed to increase the mass of an object. If the mass is increasing without bound the amount of energy required to increase the mass is also increasing without bound. Even if all the energy in the universe were utilized to speed up an object it could not reach the speed of light. It would get very close but never reach it.

Answer 3

Forget wavelength; as an object is accelerated it increases in mass, requiring a greater amount of energy to accelerate it more, then its mass increases at an even greater rate, needing much more energy, until all the available energy in the universe would be required to accelerate it any further, and it would still be below the speed of light.

Answer 4

every kind of friction
also something will eventually get in the way and stop that object

Answer 5

I will ask Einstein when I see him.
