How many galaxies are in the universe? Do you think there are life forms living on other planets?

Question

Could a new Earth be out their somewhere?

Answer 1

There are 100 billion galaxies in the universe and 100 billion stars in each galaxy.So,don't you think there can be another Earth?For life, mainly water is required.When traces are there in our own Solar system i.e. on one of the Saturn's moon -Enceladus,then why not any where else in this ever expanding and vast universe?The second thing required is oxygen, whose traces are nowadays found in many planets.Hence according to me, life forms are possible as I think, it is not necessary that life means only those present on Earth, therefore the proportion of gases can vary for other life forms.

Answer 2

The numbers are (literally) astronomical :-) ..

Over 100 billion Galaxies are believed to exist, and the number of Stars in the Universe is estimated at 70 thousand million million million (7 x 10^22) .. of which a significant fraction are thought to have planets suitable for life ...

Although, so far, no-one has found any convincing evidence of life outside Earth, most rational people believe life must also have evolved elsewhere .. see Drake Equation

So "Yes" (however see Fermi's Paradox, last link below)

Answer 3

How many galaxies are in the universe? - more than I can imagine

Do you think there are life forms living on other planets? - Yes

Could a new Earth be out their somewhere? - Yes, but it is too far away to visit anyway

Answer 4

If there are other life intelligent lifeforms out there, which given the size of the Universe, number of stars, and probable number of inhabitable planets it would be rediculous to think otherwise, you probably don't want to meet them. Especially if they were advanced enough to have the technology to visit the Earth. We would be insignificant in there eyes and the day we were discovered by them would be a very dark and sad day for humanity. (Look up Stephen Hawking's opinion of the subject.)Imagine finding a planet full of chimps or worse yet a lower form of primate and you can see the implications of what it would be like if we were discovered by something that much more advanced than we are. Although chances are we will prob never meet such a species and any life we do make contact with will most likely be in the form of single cell organisms, bacteria, or algae.

Answer 5

The universe is a finite entity so it must have a maximum size.
The number of galaxies are the ones that exist to-day.
90% of the galaxies visible to-day do not exist now.
DNA is a likely requirement for life and intelligent life like ours.
Given time,chemicals and environment DNA and intelligent,technological socities like ours are inevitable.
All the ingredient are abundent in all areas of the universe.

Answer 6

the answers are obvious - the Universe is infinite, so therefore the possibility of other galaxies is infinite - thus making the possibility of planets similar to Earth and supporting intelligent life the same - I doubt they would have the same technology, but I think that would be a great thing - IMAGINE NO WARS, NO POVERTY, NO DISEASE, NO etc etc

Answer 7

Probably billions of galaxies, I know thats hard to accept, at
least for me it seems. Yes there are definately life on other planets, including our solar system, soon our government
will have to tell us the truth about aliens, as in Mexico they
already did. As far as a New Earth, maybe in a higher dimension.

Answer 8

The 1999 hubble space telescope estimated that there are 125 billion galaxies and recently found 3000 visible galaxies.And there is no forms of living in any other planets.

Answer 9

I watched a programme yesterday that stated there were over a hundred billion stars in our galaxy and at least as many galaxies in our universe.

Part 1. Billions and billions.
Part 2. Yes.
Part 3. Not as we know it.
