New paper suggests aliens don't have technological capacity for space travel

A new paper suggests that we haven't encountered aliens because they don't have the technological means for space travel.

A new paper fromSonnenberg Observatory researcher Michael Hippke suggests that alien "space programs" might struggle with the technology necessary to send them into space, according BGR. And it's this lack of technology that could be the reason that we haven't encountered aliens yet, at least according to Hippke.

While there are plenty of proposed reasons why we haven't discovered aliens, Hippke's is a new one. In particular, he suggests that if aliens reside in the "Super Earths" that astronomers have discovered in recent years, they would have trouble creating technology to counter the increased force of gravity that comes with their size.

In other words, Hippke suggests that alien intelligence might not have the technology necessary to push themselves off of these Earth-like worlds, which are up to twice the size of our planet.

And if aliens are using technology similar to ours (such as rockets powered by chemical fuels), gravity might be an insurmountable obstacle on the "Super Earth" planets that Hippke believes they likely call home.

Seth Shostak, a senior astronomer at the SETI Institute, believes that Hippke's theory seems to suggest that humans only just barely made it into space. If this is true, it would make sense that it would be pretty much impossible to achieve similar results in a higher gravity environment.

The findings are available on the pre-print server arXiv.
