Fermi paradox

[SirUlli]

The Fermi paradox is a paradox proposed by physicist Enrico Fermi that questions the probability of finding intelligent extraterrestrial life. More specifically, it deals with the attempts to answer one of the most profound questions of all time: "Are we (human beings) the only technologically advanced civilization in the Universe?" The Drake equation for estimating the number of extraterrestrial civilizations with which we might come in contact seems to imply that we should not expect such contact to be extremely rare, depending on the values that are put into the formula. Fermi's response to this conclusion was that if there were very many advanced extraterrestrial civilizations in our galaxy, the Milky Way, then, "Where are they? Why haven't we seen any traces of intelligent extraterrestrial life, such as probes, spacecraft or transmissions?" Those who adhere to the premise behind the Fermi paradox often refer to that premise as the Fermi principle.

Yes, Stephen Hawking (forgive me if I'm spelling his name wrong) postulated about time travel using a similar concept. If time travel was possible we would already be flooded by tourists from the future. It seems like a valid concept at the surface but i don't think it should be taken as a solid premise. It is something to keep in mind, and besides, if we were all sure that nothing else exists, this fourm would be empty!!

My personal opinion is that we do not have enough information to even begin to think we can answer the age old question of "are we alone?" but projects like seti and the S&O rovers are the first step towards discovering the answer.

My two cents
