People always talk about going into outer space… yet our earth is just a giant space ship, hovering in space as it orbits the sun, also hovering in space. In a solar system that's mostly space... and so-forth-and-so-on!

Until it fries because we've abused it.

We haven't even gone to the nearest planet yet. It's a one way trip because there won't be enough fuel to come back. I read something that laid out all the problems with the "solutions" people have for that too. I will look for it and try to find it. It's taken us more than 50 years to even come up with a plan for a one way trip to Mars. Unless we have some revolutionary way of traveling come up then we aren't going to do much more exploration in space in terms of traveling anywhere. Fossil fuels are for shit when exploring space. We had a satellite that was recording information, but it went as far as right past Pluto and died. So space exploration is a bit exaggerated in terms of the hope of going to new places.
I think the more revolutionary exploration will be to "inner worlds". It's more practical.

Just remember that you're standing on a planet that's evolving and revolving at nine hundred miles an hour
It's orbiting at 19 miles a second, so it's reckoned
The sun that is the source of all our power
The Sun and you and me, and all the stars that we can see
Are moving at a million miles a day
In the outer spiral arm, at 40,000 miles an hour
Of the Galaxy we call the Milky Way
Our Galaxy itself contains 100 billion stars
It's 100,000 light-years side-to-side
It bulges in the middle, 16 000 light-years thick
But out by us it's just 3 000 light-years wide
We're 30,000 light-years from galactic central point
We go round every 200 million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light you know
Twelve million miles a minute, and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
Pray that there's intelligent life somewhere up in space
Because there's bugger all down here on Earth... Eric Idle Monty Python

Excellent reference. Thank you.
if i'm not mistaken our planet is orbiting the sun at 67,000 mph.
i remember, one night when i couldn't sleep, figuring out in my head how many miles i had traveled on space ship earth. it was around 40,000,000,000 miles which i checked & was pretty close. that was more than a few years ago.
Everything in the universe is in orbit around something. Galaxies orbit each other and the common center of mass between groups of galaxies. For instance, within the local group, the Milky Way and Andromeda orbit each other even though they are in orbits that will cause them to collide eventually.

I did that same math not too long ago myself, and the zeros kept piling up... at one point my calculator started smoking and then sizzling.
I always wonder about classic time machines. They must all be tied somehow to our frames of reference. Else how do they manage to hit the position of the earth at the time they're shooting for -- let alone hit the right place on that earth. Lol.?
