Check this video, it's from the user I posted earlier "Spacerip". Show's some footage of stars/planets orbiting a Black Hole:

And this shows even more what we're talking about, or what we want to talk about,I like what I see a dark night, look up, so overwhelming and all elusive the purpose of taking advantage of opportunities to experience.

Detecting them from their Hawking Radiation is another possibility although I'm not sure if that has yet been accomplished.
It likely will never be accomplished, as Hawking radiation involves purely theoretical, tiny particles and anti-particles that usually form in empty space and nearly instantaneously annihilate themselves. Hawking radiation involves the standard appearance of such particles at the event horizon of the black hole, except this time gravity pulls in one of the particles allowing the other to escape. The particle pulled in must have negative energy due to the Conservation law, meaning that negative particle would annihilate energy within the black hole, causing it to slowly "evaporate".

The normal annihilation of such virtual particles gives off a minute amount of energy (more precisely, it releases borrowed energy) that CAN be experimentally detected through what is known as the Casimir effect. However, without that annihilation, proving the existance of such particles will likely remain impossible for some time to come.

Go up in a small airplane and climb above 5,000' AGL on a clear night and the sky literally explodes with stars.

I have done it,

certainly not in a small plane,this was with turboprop, and approx. 600 Feet First And Then approx 6000 feet, I agree that it is a fantastic experience,and you really have a beautiful view :yep:

You get a pretty good experience by just going somewhere there's no light and looking up, we can see the mMilky Way when we're at our cottage during fall. Awesome stuff. :salute:

Yes!

True understatement :salute:

I was trying to promote folks to get above the light polution and do it slowly to enhance the experience.
