Some things are not subject to revision. I have a very difficult time 
understanding why people have a hard time with this. There are some 
things that just are, and they aren't going to change. I suppose it 
ruins possibilities for some, I don't know. Gravity, for instance, is 
precisely predictable in all situations that will be encountered by a 
human. It's never going to change. Ever. Mixing two hydrogen atoms and 
one oxygen atom will yield some heat and water. Always. That's not going 
to change on another planet, and no upstart physicist is going to prove 
it wrong.

If people are going to put forth theories with no hard data or 
observations to back them up, and those theories contradict what is 
currently known about the Universe, they should be subject to the 
appropriate negative attention and summarily dismissed. Such is the 
crucible of empirical knowledge, and rightly so.

That's where you are mistaken. Some things are final. It is true that we 
do not know what discoveries will be made in the future, but we do know 
some of what won't be discovered.

That has been my point all along. I have repeatedly and exasperatingly 
made numerous requests for more details about his experiments and he 
refuses to divulge them. There is no way to analyze observations that 
are kept secret.
