You know, the video's been up for two years, and you're the first person to point that out to me. I fixed it.

Most planets orbit far too close to their suns, for our liking. if they find another planet like the earth, then we'd be talking

Keep an eye on the Kepler mission.  That's exactly what it's designed to do.

The only reason they haven't discovered earth sized planets is due to a lack of technology. One of the most popular methods for finding a planet has to do with observing the 'wobble' of a sun. As each planet orbits it's sun, it causes the sun to wobble slightly towards the planet due to gravity and the attraction between them. The problem is that earth sized planets don't create a lot of wobble. Newer and more powerful telescopes already being deployed will change that over the next decade

I think the reason why we haven't heard from any aliens yet is because nothing is faster than the speed of light. So even if aliens were sending radio waves or other transmissions into space, it'd take a long time for it to get to earth. By the time it does arrive, the human race would probably be gone from earth.

you know what i find it hard to believe that we have not yet found a planet like our own yet but there is still lots of space to explore so you never know.
