When we talk about innovations to deal with the climate crisis, we tend to think of new technologies developed by physical scientists. Although a real sense of climate emergency now seems to be permeating the global consciousness thanks to recent high-profile campaigning, many of us have been slow to actually make changes in the way we live ourselves. Finding out what it would take to motivate people to take practical steps to reduce emissions is where behavioral science comes in. As an example, Glasgow City Council recently announced its aim to reduce net carbon emissions to zero by 2030. Some…

‘Freezing’ our bodies is the key to long-distance space travel — but can we do it?

Long-distance space travel, traveling at sub-light speeds, will require a way to make the journey with a crew of aging humans. While it’s possible to avoid some of that through time dilation (a quirk of physics that slows down time for anything that speeds up), humans wouldn’t save a large amount of time until the ship reaches 90% of the speed of light. Assuming we could build ships that can go that fast, we could cut aging in half. At 99.5% light speed, we would age at only ten percent relative to an observer at rest. The problem is physics. More…
