How many Galaxies are in our Universe?

Question

And how much matter had to leak into our Universe, from another Universe, to create what we now know to exist?

Answer 1

Who said anything about leaking matter?

Scientists estimate that there are over 100 billion!

Answer 2

More than anyone can count.  Why are so many people interested in big numbers?  Especially big numbers that no one can ever begin to count.  Just say "Billions and Billions" and let it go a that.  You will be quoting Carl Sagan and everyone will  assume you are intelligent for using such a classic phrase.  

Answer 3

Upon billions & billions of galaxies in our known universe.

Answer 4

Trillions; so many in which we cannot count. We only know as far as the 4C41.17; and that's nothing.

Answer 5

Answer 6

more than millions and maybe billions and billions of universes see we are in a ocean fill with other universes the universe expands so about millions of galaxies the universe is 100,000 light years we only scan about  100 light years  

Answer 7

There are probably Billions if not Trillions of Galaxies in our Universe.

If there are other Universes then a lot of matter leaked into ours.But that Matter had to be created from nothingness somehow.It was not just always there.

Answer 8

There are quite a few galaxies, the exact number we don't know.

Our universe did not begin as empty space - using the concept of space inherently fouls things up when considering creation of our universe.

The best idea we currently have is the big bang - I'd say God had an o****m.  

Answer 9

there is a rough estimate of about a hundred billion galaxies

Answer 10

There are hundreds of billions of galaxies. There's no way we could count them all. The matter in our Universe didn't leak into our universe, it was there are mass/energy from the beginning.

Answer 11

There are probably billions of galaxies... Hubble took the historic "Deep field" picture, supposedly of empty space, and revealed upwards of 20,000 galaxies;  if there was an equal number of galaxies in the same area of view all around us, the estimate is more than a trillion galaxies.  

Answer 12

Billions and billions

Answer 13

There are no one answer to any of your questions just theories like M theory. No one knows the number of galaxies but there are a lot for sure we can not see them all. As for the matter there is M theory saying matter does leak into this universe but how much we don't know.

Answer 14

For example, in 1999 the Hubble Space Telescope estimated that there were 125 billion galaxies in the universe, and recently with the new camera HST has observed 3,000 visible galaxies, which is twice as much as they observed before with the old camera. We're emphasizing "visible" because observations with radio telescopes, infrared cameras, x-ray cameras, etc. would detect other galaxies that are not detected by Hubble. As observations keep on going and astronomers explore more of our universe, the number of galaxies detected will increase. For more about the Hubble Space Telescope, check out this web site:
