Look at them all chasing the big yellow thing!

That there... Is cool, really. Also, quite how I imagined it. Elliptical orbits my ass; they are cork screws in 4D-space.

Good stuff! I could read about space shit all day every day.
It's one thing I'm trying to teach my kids and hope they take interest. It amazes me how many people live in their little box and couldn't care less about this universe in which we reside!

This also shows why time travel, if possible, would need a spacial displacement component as well. You can't just can't go back in time you have to move in space as well.

OR you could just emerge somewhere else. Time travel does not need to have practical applications to be cool.

This is partly true. But given that, proportionally, most of the Earths trace through space is space you'd come out in space not on the Earth.
And what if you came out inside the Earth rather than on its surface?

No doubt time travel is a great fictional plot device but practically it's a non-starter.

QuoteWe're thirty thousand light years from galactic central point
We go 'round every two hundred million years

Well I think it's bloody annoying.
Why can't they stay where they're put?  >:(

It was that bloody Galileo that ruined it all.  They should have burned him.

Oh, me, I wouldn't go. I'd send a probe full of sensors and microprocessors and a comms array.

I'm time-traveling right now... just can't find "reverse". And I'm stuck in 1st gear.

At least you are in first. :-( My time machine seems to have a nine-speed automatic gearbox that can't decide whether the eighth is the proper thing to be in or the ninth.
