there are 70,000 planets with life forms, what do you think?

Answer 1

I think you know a very small fraction of our galaxy with that claim. There're more.... many more.

Answer 2

I think anywhere there is liquid water will support life, but it might only be bacteria in 0.1-10% of places...but I think a better way to look at it is with a 10 billion years span...DID complex life exist in many places...it's not likely that 70,000 planets currently supports complex life in this galaxy, but it is likely that many more than that number has or will exist in this galaxy...I would say anything above insect or mollusk would be complex life....and of that number maybe only a several thousand developed anything as smart as a dog or cat...I do believe having some sort of life is rather normal. I would suggest that 50 million stars could have some life in their planets in this galaxy since there are 100 billion stars that's 1/4 of one percent, but the actual number is certainly much smaller probabably 1/100 of one percent that's 10 million...if a star is too close to the center of the galaxy or in the area of an arm that is exposed to large condentrations of other stars, the chances of large amounts of debris between stars would send many more planet killing comets into the star systems...as well as intense radiation. Then the star must have planets and these planets must be within a certain distance from the star--This last point is the difference, I believe...I think there could be many many planets with soil microbes outside what we would consider optimal living conditions, because these microbes would be deep in the soils and rock...they might be simple anaerobic creatures though...my guess is that in the last million years 10,000 very advanced creatures like us or at least stoneaged us have appeared and likely to be lizard, mollusk, fish, or insect, or even plant or fungus--all taken to a higher level...primate is probably extremely unlikely, although mammal is a possibility. I think the way it happened here on Earth is probably the norm with mollusks, worms, sponges and corrals being the first type in most locations...what happens after that is due to chance and the possibilities widen exponentially

Answer 3

I watched a NASA film in Athens Greece planetarium They estimate there are 100000 planets with life in our Galaxy only,and there are 200 billion galaxies

Answer 4

Do you really think that Earth is 70,000 planets?

Answer 5

It doesn't make any difference . There are so far away we may still never communicate with each other.

Answer 6

Did these life forms tell you that? Where are you getting your information?

Answer 7

In each galaxy.

Answer 8

There has to be much more than that!

Answer 9

I think your estimate is WAAAAAAYYYYY too low!

Answer 10

I think that is a LOT.
