Crunching the numbers leaves little doubt in the minds of many scientists and broad thinkers
Space news – We can estimate the number of galaxies and thus approximately how many stars there are in the universe. Can we extrapolate the number of possible intelligent lifeforms in the universe? Lifeforms with an advanced civilization and technology?
NASA astronomers are finding more and more planets orbiting distant stars using the Hubble Space Telescope. Space scientists on Earth find microbes still surviving after thousands of years frozen in ice and thriving in environments we once thought hostile to life.
Astronomers estimate the Milky Way contains around 400 billion suns, give or take a few. Sol is only one of these stars. They also estimate the universe holds a minimum of 125 billion galaxies.
If we crunch the numbers a bit, we find the universe contains roughly 400 X 125 billion billion, or 50,000 billion billion stars. We won’t at this time include the number of planets per sun in the universe, which would make our estimate even less precise. NASA space scientists and astronomers haven’t determined this number and the knowledge we have now isn’t sufficient enough to come to even a rough estimate.
How many of these suns have intelligent life living on a planet in orbit with a highly advanced civilization and technology? In future articles, we’ll try to narrow this number down a bit, by estimating the number of intelligent life forms in the Milky Way.
