Ten billion trillion planets like Earth could exist in the universe, claims an expert. The massive number, with 22 zeroes, comes from astronomer Alan Boss who reckons each Sunlike star has a world like ours . Many could have simple life forms more common to what Earth was like about up to four billion years ago.
The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations.
The extreme age of the universe and its vast number of stars suggest that if the Earth is typical, extraterrestrial life should be common. In an informal discussion in 1950, the physicist Enrico Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exist in the Milky Way galaxy, evidence such as spacecraft or probes are not seen. A more detailed examination of the implications of the topic began with a paper by Michael H. Hart in 1975, and it is sometimes referred to as the Fermi-Hart paradox. Another closely related question is the Great Silence — even if travel is hard, if life is common, why don't we detect their radio transmissions?
There have been attempts to resolve the Fermi Paradox by locating evidence of extraterrestrial civilizations, along with proposals that such life could exist without human knowledge. Counterarguments suggest that intelligent extraterrestrial life does not exist or occurs so rarely that humans will never make contact with it.

Interesting article, good find Deathpoet69.
But that was some tangent you went on about humanity and negative energy, thought it was pretty funny simply because of how random it was.
Anyway I appreciate the interesting article and the entertaining discourse.
In relation to the article though its a shame it doesnt give detail as to why the scientist thinks this to be the case.
I mean he doesnt say why sun-like stars should have planets. Are planets formed inside of then ejected out of stars, or what kind of process is responsible for creating planets orbiting stars on such a consistent basis?
