So, I've never been able to understand where the extra mass comes from when an object is traveling near the speed of light. The same for length, where does the excess length go? Also, why does the object increase in mass. I'm pretty weak in relativity.
I understand the equations and that's usually good enough but somebody asked me why it gains mass and where does the mass come from and I don't know what to say.
Any help? Thanks.
