The possibility of running across an alien intelligent race in our solar system is negligible.
The consensus of scientific view says, with quite good reasons, that the p~ssib.lity of running across an alien intelligent race in our solar system • s negligible.
The most widely held theory of stellar formation would predict the formation of planetary systems to be a natural consequence of stellar evolution.
The most widely held theory of stellar formation would predict the formation of planetary systems to be a natural consequence of stellar evolution.
There is a huge number of planets in the galaxy, and life is quite likely to arise spontaneously on a large number of these.
Thus, we have the current scientific theory and data not only that there are a huge number of planets in the galaxy, but that life is quite likely to arise spontaneously on a large number of these.
The discovery of both Martian moons within a week in the latter part of the Nineteenth Century indicates they are large artificial space stations.
many flying saucer advocates claim that the discovery of both Martian moons within a week in the latter part of the Nineteenth Century indicates that they are large artificial space stations, otherwise they would have been found earlier.
If we were to discover Martians on the moon, it would result in surprisingly little readjustment of our scientific thinking.
If we were to discover Martians on the moon, it would result in surprisingly little re- adjustment of our scientific thinking.
The probability that we will find another intelligence race is finite and perhaps should not be completely ignored.
Although all plausible scientific thinking suggests that we will not find any other intelligence race, the probability that we will is finite, and perhaps should not be completely ignored.
