There are a lot of stars in the universe. Our Galaxy alone is thought to contain 400 billion stars. If you can count 2 stars a second continuously without sleep it would take 200 billion seconds or 6337 years 225 days 13 hours 33 minutes and 20 seconds.
Add to that the fact that there is thought to be about 400 billion galaxies in our universe. Our Galaxy is large by galaxy standards but let us assume that the average number of stars in any given galaxy is 100 billion. So at 2 a second it would take 633.7 trillion years or to put it into perspective 46,154.4 times longer than the universe has thought to existed.
Since it is not possible to SEE the stars in Andromeda, it would take forever. Of course, if you can wait 3 billion years until Andromeda collides with the Milky Way, it will be a little easier.
It would take a prohibitively long time. A "googol" is 10100 (a very large number). There are only about 1080 atoms in the observable universe.
400 billion seconds. (almost thirteen thousand years) By the way there are probably no more than 200 billion stars in our galaxy...
Well considering stars die and are born all the time, the number would change all the time. However, at the current estimate of 300 billion stars. At one a second a star, it would take about 9,500 years.
To learn more about the universe. For me personally, I enjoy getting outside at night and observing. I look at stars that change in brightness - variable stars - and this contributes to our ongoing long-term database.
That depends on how fast you can count.
Answer #1:A long time.......=====================Answer #2:Classically, it would take(the diameter of the universe, in miles)/(5,878,464,424,000) years.
It would take about a googolplex - it doesn't make much difference, in this case, whether you are talking about googolplex of nanoseconds, seconds, or millennia. Nor does it make much difference whether you count a million numbers every second, or take a year for each number. In any case, it would be much, much more than the current age of the Universe.
If it didn't everything in the universe would have gone flying apart long ago and there would be no universe!
The first neutron stars likely formed some time in the first 600 million years after the Big Bang when large stars of the first or second generation died.
It would take nothing
Humans have long been fascinated by stars, often attributing them with symbolic or spiritual significance. Many cultures have used stars for navigation, time-keeping, and storytelling. Studying stars also helps astronomers understand the universe's origins and evolution.
