Space travel is not as easy as conjectured. Traveling at the speed of light is too slow to get you anywhere and requires massive amounts of energy. The probability of contact with life forms on other solar systems or galaxies is small. If there are other civilizations, they have no reason to even believe we're here. At the speed of light, they haven't even received our 50s TV sitcoms yet.

That's only 50 years. Fermi was talking about 10 million. Why aren't we picking up their sitcoms?
