Universe in not infinite. It is finite and constantly expanding. Yes there are more galaxies than no. of grains of sands in all beaches of the world. This universe is unimaginably huge!

There are estimated to be 40 trillion stars in the visible universe. My rough estimation would be that there would be more sand grains on Earth, but we are only talking about the visible universe. I estimate that we can see less than half of the entire universe due to the expansion rate of the universe and the fact that we can see no further than about 14 billion light years in any direction. With the universe being about 14 billion years old and that 2 points in the universe that were beside each other 14 billion years ago, there would now be a distance of 28 billion light years separating these two points now and we can only see back 14 billion light years. Therefore there should be more than twice as many galaxies than we think are out there now and then i would say that there are most likely more stars in the universe than there are grains of sand on all of the beaches in the world.

There are more grains of sand on all the beaches of the world than known galaxies! That is allot of sand!
The universe is part of an even bigger universe.
Grand Universe: One huge empty space beyond all universes.
Central Universe: One area of space within the Grand Universe where Creation (God) resides.
Super universes: Seven areas of space within the Central Universe. Each Super universe is equal to 100,000 universes.
Universe: Has 100 Constellations with each Constellation having about 100 Systems. Each System represents a group of planets.

As a part concern, the calculations of the type of stars and galaxies interior the universe is unquestionably basically what's called the Observable Universe. it particularly is the area in each and every course from us to approximately 13 billion gentle years. it is believed that the total Universe is greater than the quantity we are able to work out, the Observable Universe. As extraordinary because it may desire to look, the two between here issues are curiously genuine concerning the universe: a million) there is not any findable end or edge of the universe by shifting in 3-dimensional area 2) the quantity of be counted and potential interior the universe is finite. It would not have a limiteless variety of stars.

conservatively 100 Billion galaxies. I haven't counted the sand yet. But I think the comparison is for stars, not galaxies. There's approximately 50-100 Billion stars in each of the galaxies mentioned above. That's a lot of sand...

The number of Galaxies counted by astronomers as indicated in the latest estimate is 400 billion galaxies, each of which contains more than 200 billion stars.
