There is a guy named Tom.T.Moore, who says that scientists won't find out before the 2500s that the pineal gland is NOT a residual organ but fully functioning.

He also says that Earth will "prepare for the stars" not before the 2700s, and that his own next lifetime will be in the 3500 era as a female pilot of one of a total 14 spaceships on Earth. The way he receives these insights is very similar to the way I receive mine, so I found. He knows a little bit about his next four lifetimes.

And yes, lightspeed is indeed not the quickest travel pace! ;)
