This guy claims he went to Mars last year. It isn't even convincing as science fiction. I immediately spotted several big flaws in his story (like how nobody noticed the launch or spotted them toodling around on the Martian surface) besides the usual conspiracy-fail of "I'm in hiding and in...

OK, seriously. We all know the nearest stars are the Centauris. They are 4+ light years away. The most recent possbile habitable planet found is in the solar system of Gliese, which is approx 20 light years away. We all know how fast light travels, so I will spare posting the numbers on that(in...

I’m not necessarily taking this poster seriously but it was thought provoking and it looked like it would be a fun question to throw out. So did Christianity have a serious impact on scientific advancements or were other influences like invading barbarians the real culprit?

India's lunar probe lands on the moon, sends images Am I the only one who thinks this is incredible and wonders why so little attention is being paid to the #2 guys here in Moon landings? Ho hum, been there, did that?

I was reading this article on New Scientist http://space.newscientist.com/article/dn13393-nearest-stars-wobbles-could-reveal-earths-twin.html?feedId=online-news_rss20 I was wondering if someone here could come up with some realistic numbers for an attempt to travel to Alpha Centauri. A nuclear...

I'd like to comment more on this, but don't have the time right now. See http://video.google.com/videoplay?docid=1996321846673788606 for a talk given at Google. According to a very bright, Princeton educated physicist Robert Bussard, who has successfully created fusion in small, magnetically...

While preparing someone for his exams, I had a thought...Yes me... Since the average distance between stars is 8 LY ~ 75 mill.mill km, what chance has the human race got of ever actually Star Trekking? What's our best so far Apollo? About 60,000 kph [0.06 Mill kph] so that would take us to...

Spacecraft use gravitational sling-shots to gain energy travelling around the Solar System. Could this be used on an interstellar scale? I'm thinking more science fiction than planning my own emigration to Alpha Centauri. If the hard work was done to get people and resources out of our Sun's...

The talk about justifying the NASA budget and continuing the space program often waxes about space colonization. I think those people watch too much Star Trek. We are never getting off this planet and we better learn to live and take care of it without the silly pipe dream of going somewhere...
