But essentially it is possible with all the right equipment yes?

Thanks

Looking back through time So we all know that some the stars we can see on earth, as we see them, are as they were hundreds of millions of years ago due to the fact that light only travels so fast. So, hypothetically, if someone were to make a mirror and Send it out into space a hundred light years from earth. In two hundred years, would someone be able to see through that mirror and look at the earth as it is right now? could they see individual people and watch them?
