Is relativistic mass real

One of the oddest features of special relativity is the inability to go faster than the speed of light and this is absolutely true. The most common explanation is that the mass of an object increases with speed, but this particular explanation simply isn’t true. In this video, Fermilab’s Dr. Don Lincoln explains the truth behind this. (And, no, don’t send him emails about how this proves relativity is wrong. He is a strong believer in properly-understood relativity.) Dig in deeper here: https://arxiv.org/pdf/hep-ph/0602037.pdf
