There is no speed faster than the speed of light?

    How do scientist know that there is no speed faster than the speed of light?

    Could anything be faster, even forces?

    can you please link me to a site where they have the explenation of why light is the fastest thing

    The explanation lies within' numbers.

    When the Michelson-Morley experiment showed that light is constant, the result of this, theotically, resulted in that the speed of light is not obtainable or can not be surpassed.

    Pick any Special Relativity, and it will explain it to you.

    Note: I don't know the proof of this myself, but I do know that it is the consequence of light being constant.

    Einstein postulated that the speed of light is constant (based on observation and failure to detect the "ether") and that the laws of physics are the same in all inertial frames of references. If those conditions are true then it follows that no material object can ever be accelerated up to or beyond the speed of light. Essentially, it would require an infinite amount of energy to do so.
