President Trump is struggling to find a place in history, other than being the worst president his country has ever had. On more than one occasion he has expressed views about returning to the Moon, sooner rather than later. My guess is that he sees an opportunity to make money from whatever resources people might find there.
It’s a bit Kennedy-esque, I suppose, certainly the commitment (if that’s not too strong a word).
We (mankind) landed on the Moon in 1969, and by late 1972 the whole programme was over. Nearly all the men who walked there are dead. The USA achieved something magnificent, but do not have the resources or technology to do it now. With the ending of the space shuttle, they do not have a proven method of getting humans into orbit even.

I love a good science fiction film, but there are things that always puzzle me. Here are a couple.
Why do doors on spacecraft nearly always open automatically? Are crewmen so lazy they cannot open a door?
The spacecraft we have had so far in realy have had a problem – weight. Every gram of excess weight needs more fuel. Most of the Saturn V rocket was designed to lift, well, itself. The payload was minute. Surely, excess weight for door opening motors would be avoided at all costs.
And have you noticed, when people want locked doors to open they shoot them with ray guns? And when they want them to lock, they shoot them with ray guns.
And what about transporters? They are amazing things. They are machines that take every molecule of an animate or inanimate object and transfer them instantly to another place where they are reassembled perfectly (except when the plot demands they are not working properly) without mixing them up.
The destination doesn’t even have to be another transporter machine. People just appear anyway (or disappear) from thin air. In fact, you can transport from one place without a transporter to another without a transporter. That’s a miracle.
And they must be so deadly accurate, to within the tiniest fraction of an atom. If a person is being transported onto a surface and is just a little bit too low, their molecules will meld with the molecules of the floor and they will be stuck. Too high above the surface and they will fall the last distance and possibly be hurt.
The biggest problem with my amazing number theory is this: it’s all made up. Fake news, if you like, though it’s hardly news.Yes, I just invented the whole lot.
The figures are wrong. Admittedly they are believable, and not terribly far from the truth.
There’s a whole load of pseudoscience that just makes things up, or is selective in the data used. Vast claims are based on thin evidence, or none.
I remember being intrigued when I was young with books about the Bermuda triangle, or was God and astronaut? The fact they are nonsense and have been thoroughly debunked does not stop people still believing in these things. Or that the Earth is flat and space does not exist.
James Randi did a good job debunking faith healers, but people still go and give their hard earned money away. And people seriously follow horoscopes too.Continue reading
