If you counted 1 number per second, it would take 5700 years to count all 180 billion star systems in the Star Wars galaxy.
Counting one star per second, it would take approximately 12,680 years to count all 400 billion stars in the Star Wars galaxy.
I don't know if it's 200 billion or not. Never know.
Yes. An average galaxy contains at least 100 billion stars.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
The average number of stars in a dwarf galaxy is several billion.
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.
If you counted 1 number per second, it would take 4000 trillion months (320 trillion years) to count all 10 billion trillion stars (100 billion per galaxy) in a fictitious version of our universe.
If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
Yes. Some dwarf galaxies do contain 1 billion stars.
The average number of stars in a dwarf galaxy since it contains a few million to several billion stars with as few as ten million (107) stars.
Since T2003 767 is an elliptical galaxy 12.5 billion light years from us, it will take 12.5 billion years for the message to reach its intended designation (and an additional 12.5 billion years for any reply from an alien civilization).
Since MDC2010 1721 is a dwarf galaxy 13.1 billion light years from us, it will take 13.1 billion years for the message to reach its intended designation (and an additional 13.1 billion years for any reply from an alien civilization).
