There are around 10^10^10^7 Universes.

Stanford University in California physicists Andrei Linde and Vitaly Vanchurin decided to take on a task that seemed impossible to complete, namely to determine the variety of instances of the Universes that had been formed after the Big Bang. The number they found was qualified as “humongous.” The two physicists say that some 10^10^10^7 Universes were created when the elementary particles that created our Universe collided.

There are talks of other universes also but nothing concrete has been established and these look like fairy tails.

Hence we believe in only universe in which we and the whole solar system is existing.

Our universe is 13 billion years old. They came with this estimate by considering the light year. Nearest star is 24,000,000,000,000 miles away from earth. But we cannot write this 20 digits everytime to consider the distance between celestial objects. So they came up with light year. Light travels at 186,000 miles per second. Therefore, a 1 light second = 186,000 miles . A light year is the time that light travels, some X distance in 1 year (i.e 365 days). That is to reach thee nearest star, with the SPEED of LIGHT, it takes 4.2 light years. If this star died today, we can still see the star, as the light from it takes 4.2 light years to reach earth. In simple way, if that star died today, we will come to know that it died ONLY AFTER 4.2 light years and we will continue to see this star everyday until 4.2 light years from today. Interesting, Rt?

So the farthest star (i.e its light) takes 13 billion light years to reach EARTH, i.e our universe age.

Assumptions: There may be more than one universe existing parallel to each other. If u consider a sheet of paper as one universe, place another sheet of paper parallel to each it, then its another universe, likewise u can place enormous number of sheet, making infinite number of universe. This is just a theory, not confirmed.

And one can arrive at other universe using a worm hole. That is put a pencil (perpendicular; 90 degrees, to the sheets) between these TWO SHEETS of paper. Then pencil is a worm hole.

Albert Einstein proposed the theory of worm hole for only one universe. His theory is we can bend the universe and reach other side of the universe within less time. Example, on a SINGLE FLAT SHEET (i.e only ONE universe), mark 2 points, say X and Y. Now bend this SINGLE SHEET of paper so that X lies above Y. Take small pencil and join X and Y with it. This pencil is worm hole. If u put the paper flat, to reach X to Y takes longer time, but when u bend the paper, through worm hole/pencil u could reach in minutes (just like the American TV serial STARGATE ATLANTIS). This bending the universe can happen by actually bending the SPACE and TIME. If we can bend SPACE and TIME, we can TIME TRAVEL. Who knows that our future generation time traveled and are in our presence now or may want to warn/help us?.
Note: WORM holes are made by opening the gates of blackhole and whitehole and connecting them.

Also scientist have found an interesting evidence regarding our galaxy. Our spiral shaped MILKY WAY galaxy is in the process of merging with a very small galaxy, but there is NO harm to earth, as SUN is far away from any collision with another star (from that small galaxy) due to this merging. Also SUN is at the edge of MILKY WAY GALAXY spiral wing.

As per our current knowledgde, there is still no definite, absolute proof of any other univers but the univers itself being all there is. But still, 2 different theories are still in debate to if there is multi-verse or univers.

I have given you here the most recent position regarding this worldwide renoun astrophysicien Mr. Steven Hawkins. Is word is pretty much what the rest of the worl agrees on.

"For thousands of years, people have wondered about the universe. Did it stretch out forever or was there a limit? And where did it all come from? Did the universe have a beginning, a moment of creation? Or had the universe existed forever? The debate between these two views raged for centuries without reaching any conclusions. Personally, I?m sure that the universe began with a hot Big Bang. But will it go on forever? If not, how will it end? I?m much less certain about that. The expansion of the universe spreads everything out, but gravity tries to pull it all back together again. Our destiny depends on which force will win."? ?STEPHEN HAWKING
