scientist from 1965 claims that the moon is made of plasma

A scientist from 1965 claims that the moon is made of plasma and that it is not possible to land on it.

Now one thing, you have a theory about the moon and we expect to be able to get observable facts about the moon fairly soon. What is your theory?
- Well it is by now rather more than a theory. Ten or eleven years ago I stated to various scientists that the moon is not a piece of rock but it is a plasma, a plasma phenomenon, a cosmic plasma, and that this fact will eventually be confirmed. I made certain predictions which were already confirmed in 1958, and the situation now is coming close to a complete confirmation.
What will be the result if you are proved to be correct in your theories?
- The result will be profound and decisive, because it will give proof that a complete reinvestigation of the laws of nature is necessary, because if the moon is a plasma, no man will ever land on it, the soft landing attempts will all fail. That means that the mass of the moon is less, far less, than is currently assumed. It's in a different state of energy, and it has far less mass. That means there is no more explanation for the tides. If the Moon, for example, had only a thousandth part of its current mass, then the tides would only be two inches high, and the conventional theories instead of sometimes 14 feet. And that means that if it is proved that the Moon is a plasma, then all gravitational theories are out, and the new concept of the cosmos and of its laws has to be evolved.
Aren't you being a bit adventurous, though, because you know we're going to be able to test out your theories on the Moon fairly soon?
- Well, not anymore. Eleven years ago, of course, it was rather taking a risk. I was considered a lunatic, of course, but by now the evidence, accumulated evidence, is already so much in my favour that I'm not taking any risks anymore. On the contrary, there is scientific views expressed all over the world now that the moon seems to be of a quite different nature from what was assumed. But the Americans and Russians are thinking of landing men on it. Well, that will never happen. Not on the moon. On Mars, on Venus, on other planets, yes. But the moon is definitely, as I assert, a plasma.
