Obvious joke. It's clearly from a movie. |

Everything works out in the end, sometimes even badly.
if these aren't aliens then... |

That's a hoax. You can tell the UFO was digitally added in later. |

If they aren't aliens... then they are something else. |
|
It's really hard to take a source seriously when they spell their name with numbers in place of letters, like some 10 year old on AOL. |

I think that there may indeed be Aliens, because of the argument there are billions of stars and billions of theoretical planets. But then you reverse the argument: If there are billions of stars and even more planets, it is just as likely for aliens to find us then for us to find aliens. (A very low chance, considering we haven't found any proof of aliens on any planet but our own) |

Just curious, what kind of lense for hubble do we need to zoom into planets? all i know is it's not possible atm. |
|
Anything on the surface? You mean like a building or something? Or an animal? |
|
He asked what size lense you would need. |
|
Observatory telescopes have no lenses and no "zoom" (although some of their imaging instruments have different fields of view). |
|
Besides the point people. I was just pointing out how ridiculous the question was. |
|
I dunno, I'm not a math genius. Care to figure it out for me? |

This is clearly wrong... our naked eyes get better resolution than that! 5*10^15 m is about 0.5 lightyears. At 600 ly distance, this would correspond to an angular diameter of about 0.048 degrees, or about 2.9' (arcminutes). Wikipedia lists the average nighttime human eye resolution as 3', but in the daytime that rises to 2' for 20/20 vision, and 1.2' for the best human. So your calculation got wonky somewhere. I'll attempt it: |
