Is there life on other planets? from a scientific prospective...?

Answer 1

I would say probably, but we have no proof as of yet.

Answer 2

Obviously it's impossible to know for sure, but the odds are that there is. Even if the chances of life being on any given planet are very slim, the sheer number of stars is so large that there probably are some with life.
I read of a study where the basic amino acids necessary for life were created in a test tube by recreating what the atmosphere on Earth was at the time when life first formed, and then creating a spark to simulate lightning. It shows that the basic building blocks of life aren't that hard to create.
Also it has been shown that life can exist where there is no sunlight, as long as another source of energy (like the heat from the core of a planet). They have shown huge animal communities springing up near geothermal vents, so far under the water that no sunlight ever reaches. This finding greatly increases the odds that life could form on planets that would otherwise be deemed uninhabitable due to being too far from the local star.
Of course the odds are that life in the galaxy and beyond are probably too far away from us to ever meet in "person", which is why scientists in the SETI program search the sky for signals, which would travel at the speed of light.

Answer 3

Scientifically we can NOT say there is life on other planets. (assuming you don't incude robots on Mars or astronauts on the Moon). There is no good evidence of this.
Scientifically, we CAN say that based on our best understanding of the way life emerged here on Earth that it is HIGHLY LIKELY (almost a certainty). (note assumption about our knowledge being right, however).

Answer 4

I don't think there is a commonly accepted scientific definition of "life". The answer to your question will vary, depending on life's definition, from "almost certainly" (life = microbes and such) to "probably not" (life = humanoids, as found in startrek et al).

Answer 5

Yes we live on one planet out of nine in our solar system,our galaxy alone has millions of other systems and the univ. has millions of galaxies the ratio for life here equals .111 now times that by quadrillions and the answer potential planets that have life of some kind as we know it.

Answer 6

Look up the Drake Equation. famous equation from a fella named Drake (obviously) that determines the possibility of life existing in a galaxy or universe

Answer 7

i dont believe that there is advanced life as earth elsewhere most likely there is some sort of life such as bacteria or micro-organisums . earths postion in the soloar system is very unique thats why there is advanced life forms

Answer 8

Life as far as human life, no. Life as in other living organisms, maybe.

Answer 9

We haven't found any yet, not even microbes

Answer 10

yes
