There is potentially over 8 [b]billion[/b] planets capable of life in [b][i]our galaxy.[/i][/b]
[quote] By extrapolating Kepler’s findings, astronomers have come up with some not-altogether-unfounded estimates for these values. For instance, they concluded that about 22% of Sun-like stars has at least one planet we class as potentially habitable. Doing the math based on the latest estimates for the total number of stars in the Milky Way, that gives us a rough figure of 8.8 billion potentially habitable planets in the Milky Way. That’s a lot of rolls of the dice, assuming you believe life has any chance at all of starting spontaneously. [/quote]
That's just our galaxy people. There's hundreds of billions of galaxies in our universe. That's a lot of potential for life. We're not special snowflakes.

The Milky Way on its own is really, [i]really[/i] -blam!-ing big. It'd take two hundred years to traverse it, end to end, at light speed. Obviously you wouldn't go that route, but still, it's a long way, wherever it is you might want to go starting from Sol. The space between two galaxies? Forget about it. We're better off waiting for Andromeda to pass through us. I don't know, this is cool news. But space travel from where we are right now just seems so impractical.
