Based on the proposition that the further into space we peer, the further back in time we peer;
should not the furthest stars be closely grouped towards the beginning of the universe i.e. the big bang?

Since the moon trips achieved distances of approximately .25M miles one-way, and the shuttle altitude is approximately 150 miles one-way, then why don't we just go all the way to the moon?

Or have I missed something critical? What do I need to know about this to have it make sense?

Just got done watching an interesting video on YouTube about Time Travel so it sort of sparked this question.

I've read some Physics books, and watched a movie on Quantum Physics, but the question boils down to this - is time travel possible?

I've searched around, but the only actual definition I've found is from www.medfriendly.com, which says: "Aminergic means relating to nerve cells or fibers." But this is not helpful because the articles I'm reading assume a distinction between aminergic neurons and other kinds of neurons. I need to know what is distinctive about aminergic neurons. What do they do? What special roles do they play?
