One of the ways we justify going to Mars is that Earth is pretty much on the road to ruin just now, courtesy of human endeavour. We need a new planet. The only problem is that human nature doesn’t change, so we’d probably end up wrecking Mars too, likely while fighting viciously over how to … More Humanity – the scourge of the galaxy
It is 49 years, this weekend, since Neil Armstrong and Buzz Aldrin stepped on the Moon. And it was an incredible achievement – not just for the United States, but for humanity as a whole. For the first time in the history of the world, we had left it – and stepped on another celestial … More Thoughts on the future of humanity, 49 years on from Apollo 11
There’s been a lot of speculation of late about a putative ‘Planet Nine’. No, Pluto hasn’t been restored to proper place – this one is a new idea, proposed in 2014 by Chad Trujillo and Scott S.

The resulting article consisted of the words ‘nobody knows’, repeated 250 times. That point’s still true today. There are plenty of clues that point towards the idea that life … More Are there aliens? Nobody knows…
Lately space science has made a slightly disturbing discovery. Space travel makes you go blind. Really. It’s a bit of a surprise, given that in other ways science has found solutions for most of the biomedical problems of free fall and, along the way, learned an awful lot about osteoporosis, which is a spinoff of … More Don’t space travel. You’ll go blind.
One of my pet irritations with some science fiction is the way authors often succumb to the ‘recency effect’ when inserting the ‘science’ part into their stories.
