U4T1: SPECIAL RELATIVITY

An infinite amount of energy is needed to have an infinite amount of momentum to travel at that speed. Having an infinite amount is not possible therefor no object can reach the speed of light.

Einstein's mass energy equivalence relationship indicates that mass and energy are equivalent.

Time dilation and length contraction.

<p>High energy cosmic rays strike oxygen nuclei in Earth's atmosphere at around 15km in altitude and produce muons that travel at 99.97% of the speed of light. Muons are unstable and Newtonian physics say muons should travel about 659m before decaying. However, the muons created by this process are detected on Earth surface 15km below.</p> Signup and view all the answers
