Why do you put in the effort to comment but not the effort to read the article?

There is already a secret space program that does everything they want and more.

Reply to comment by [deleted] in If we were able to teleport to the nearest star outside of our solar system and had a strong enough telescope to look back at earth; we'd be seeing 130,000 years into the past due to the speed of light by AfterZookeepergame71
When you open your eyes you only see light. The image you see is light and nothing else. If you had strong enough telescope (we'll ignore how big it would have to be just for the sake of the argument) and looked at the earth from 100 light years away you would absolutely see into the past. You would see people in 1920s walking around in their old timey outfits talking about 1920s stuff in their 1920s cars.

You wouldn’t be SEEING anything homes! You chose to travel to a star! The heat! The brightness alone!!! But…..with balls like that kid. I think you might just be mad enough to pull it off!

Nearest star outside the solar system is around 4 light years away. This was probably referring to something else.

130,000ly is about the distance to the Large Magellanic Cloud, a companion galaxy to the Milky Way. Did you mean to teleport to the nearest galaxy, rather than the nearest star?

You wouldn’t be seeing anything except light anyway, you’re not seeing into the past just light that’s catching up to your location… it’s not like your going to be looking at dinosaurs or the the birth of man.

No.
The nearest star is only a little over four light years away. You'll be able to look back at the Trump presidency.

130,000ly is around the length of M31 or something like that.

Isn't that 130,000 light years? No criticism or negativity intended, it's an honest question, as I know too little of space.

The nearest star is only about 4 ly away, so you'd be seeing 4 years into the past.

The military has plenty air training ranges. When they’re not in use, they work pretty much the same as normal airspace. When they’re hot, traffic is just vectored around them, under them, or over them.
Trouble with this though, due to the cost of moving stuff around up there, a space range would effectively be exclusive use.
That being said, space is vast and three dimensional. I’d have to see how big a slice they’re asking be set aside. Chances are, it’s not a lot.
Good luck getting them to say what’s happening up there, though.

I did. Why do you believe that SpaceForce will use anything else than rockets as they don't want to admit they have other methods of propulsion?
