5 Things Interstellar's Science Gets Right (And 5 It Doesn't)

3. Other Inhabitable Worlds Might Exist

It's unlikely that, in the event that the Earth became uninhabitable (which isn't going to be for a little while, just so you know), humanity will find any other planets in our own solar system with with to emigrate to. Mars is way too hot, the atmosphere on most of the rest of them would be borderline toxic, and we can't even make our mind up as to whether Pluto's a real planet. Imagine the shame of living somewhere that isn't even a real planet. How would we be able to show our faces at the intergalactic meetings we'll probably be having by then? In which case, having a wormhole to fling ourselves off to a distant, different galaxy would definitely help. In fact scientists have long been theorising as to what worlds might exist beyond our own humble solar system. Earlier this year, in fact, NASA happened upon Kepler-186f, a planet which resides about 500 light-years away from us in the constellation Cygnus. It's years are 130 days long and it gets one-third the heat energy that we do from our sun, but it has enough water an atmosphere that could sustain human life: roughly a similar distance and challenges to the planets that the Interstellar astronauts were surveying.
