00:00are aliens out there and if so are they advanced enough to leave their planet and begin looking
00:08for other intelligent life as we have those are questions scientists have been looking to answer
00:13for decades but now a new paper looks at that possibility and what it would take for the
00:17hypothetical extraterrestrials to make it out into the cosmos a big part of space exploration is well
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
00:32as an exoplanet 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
01:13world halting aspirations for traveling to space or what if their planet has constant cloud cover and
01:18they never even get curious about what's beyond their atmosphere
