To think that possibly at this precise moment on a planet that has yet to be discovered (and pillaged) there is someone else writing down their thoughts on whether or not other civilizations exist makes me a little paranoid. It also makes me yearn... read more
There is almost a 100 percent chance that there is a huge amount of life in the entire universe.
At our current state of knowledge, we can only talk of probabilities, and in all probability there is a great deal of life in the universe beyond our Earth.
Let's talk facts. There are probably an average of 100,000,000 stars in each galaxy. Some galaxies are larger, some smaller. And there are estimated to be several billion galaxies in the universe. In rough figures, we're talking about 1,000,000,000,000,000,000 stars, each of which may be a sun to its own set of planets. More stars exist in multiple systems than as single stars like our sun, so this may be an upper estimate for planetary systems.
A study in the last several years found that complex chemicals that may ride on meteroids will gain in complexity when they strike a planet's surface. While this seems cointerintuitive because we typically think of things being torn apart by such energetic collisions, this implies that the building blocks of life could have been formed by such collisions.
Did the final step require the hand of God, or did the source of the universe already have in place the mechanisms to take complex chemicals all the way to primitive life forms? Or was it all accident? We may never know the answer to this last part, but scientists are still working on it.
Scientists and engineers are also working on spacecraft and equipment to detect extrasolar, Earth-like planets. If free oxygen is detected in the atmosphere of any such worlds, then we have as likely an indicator of life as any. Molecular oxygen does not typically occur in nature without life performing something like photosynthesis. We may be only a few years from having an answer.

Beyond the earth, is sky. Beyond the sky, is universe. Can you guess what is beyond the universe ?It may be related with science, but I don't know to which it is related.

Many scientists believe their is life on other planets. Not on Mars or Venus but in the next Solar System. What do you think and should NASA take this issue seriously?
