Relativistic Momentum: Mass, Time & Distance

[Gokul43201]

This comming after a year of me posting that comment?

What comment? I'm talking about posts in this thread, all of which have happened over this past week.

The true definition of the term "mainstream" means:

mainstream; a prevailing current or direction of activity or influence

Yes, that's a reasonable definition.

So what? It doesn't matter what the crowd things.

By your definition above, it is the "crowd" (or the prevailing current) that determines what is mainstream. If you disagree with the crowd, you are disagreeing with a mainstream idea.

I was responding this year, the year in which the person addressed my paper and as such it was my paper which became the subject matter.

Again, I have no idea what you mean by all this. In this thread, it was you that brought up your article, not someone else.
