Are aliens out there? And if so, are they advanced enough to leave their planet and begin looking for other intelligent life as we have? Those are questions scientists have been looking to answer for decades, but now a new paper looks at that possibility and what it would take for the hypothetical extraterrestrials to make it out in the cosmos.

00:23getting into space and that's a lot harder on larger planets like super earths the planets
00:28escape velocity and other mathematical values would have to fit into what the new paper outlines as an
00:33exoplanet escape factor which the author has crunched the numbers on some nearby exoplanets
00:38as seen in this graph here finding quote values of fex greater than 2.2 would have space travel
00:44unlikely for the exoplanet's inhabitants they would not be able to leave the planet using any conceivable
00:49amount of fuel nor would a viable rocket structure withstand the pressure involved in the process
00:54at least with the materials we know this is an interesting find because it's based not on the
00:58probability of there being life on other planets but rather our ability to ever encounter them based
01:03on physics the author also suggests that depending on how the civilization develops they may never need
01:08things like telecommunications meaning they might never conceive of how to communicate with those off

01:18they never even get curious about what's beyond their atmosphere
