Arthur C. Clarke thought cold fusion was real, with 99% certainty. But the science establishment would not approve of funding research into it, not because it didn’t work, but because the theory behind it was unknown. In other words, they could not confirm it was not magic.
This video is an interesting lesson about the scientific establishment for creationists. Creation, like cold fusion, is opposed, not because there is no evidence for it, but because there is no recognized theory of how it could work by known processes. This is the trick played on modern man: atheism is substituted for science. There can be nothing recognized as unknown by man, or he cannot be his own god.
