[QUOTE=DeanWinchester;41273898]Quick space question guys, I'm not one to believe in UFOs and any other kind of stuff without proof (including religion). I was having a smoke right now, looking at the night sky (3:45 GMT/UTC) and I see this bright flash of light in the general direction of Sirius, it only lasts for about half a second and then goes off, at first I thought I just imagined it so I kept looking and I see it again about 10 seconds later, but it had moved quite a bit. So, I kept watching and it does it again, every time it blinks really bright for half a second then goes off for 10 seconds or so, I lost sight of it when it was in the general direction of Ursa Major because my balcony didn't allow me for a larger line of sight.

What the hell was it? My first thought was the ISS or a satellite rotating around in space and reflecting the sun every so often, but I thought those were geosynchronous so it shouldn't be "moving" that fast because it should follow the rotation of the Earth.

Or maybe it was the second coming and I may need to find the other two wise men.[/QUOTE]

Black holes make me feel paranoid as shit. I mean, they're terrifying.

What would happen if an amount of antimatter equivalent to the mass of a black hole were to enter said black hole?
