Doesn't it also apply to anything with mass? Some hypothesizers (theorists?) have come up with the idea that if mass could be eliminated then something could travel past c. Others would manipulate gravitation or expand/contract spacetime.

Notably, only travel at c is supposedly prohibited, but travel faster or slower could happen (hence tachyons).

Not in my book. Everybody is free to write his own book, of course. Until somebody does in fact get the dry cleaning back from Alpha Cent by 8:00 tomorrow morning, the final book hasn't been written.

How can you eliminate mass? I thought mass couldn't be tampered with, but maybe itz jus' me publick skool fisicks.
