Yes, we can. We can totally create the artificial gravity seen in movies like 2001: A Space Odyssey or Elysium, it will just cost a lot of freaking money and require a lot of freaking resources. Real Engineering explains how centrifugal force works as artificial gravity and estimates (using maths cribbed from how much the ISS costs) the cost needed to build it: only around five trillion dollars and 10 years of the world's total aluminium production. And that's just for starters.

Yesterday, the US House Science, Space and Technology Committee met with NASA and leading aerospace companies to discuss future deep space habitats. As US Congressional hearings go, it sounds like an enthralling topic.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.
