Imagine the look on his face when his experiment flies up to the ceiling.
The theory of evolution for example is still just that, a theory. Not proven yet, however most all in the scientific community believe and use it as fact. How about you? You seem to love science so much, do you believe in the "theory" of evolution?
Ahh, actually the "theory" of evolution is called Natural Selection. It is an attempt to explain the "fact" of evolution, which is found in the fossil record, our biology and our DNA. Think of it this way:
The theory of gravity attempts to explain why stuff fall to the ground. The theory of gravity has changed, it used to be Newtonian and then it was replaced by Einsteinian physics. When this theory changed (more like an adjustment), things still behaved the same way. Stuff still fell to earth just like before, the planets still orbited the sun.
So yes, I believe that the current theory of evolution, or Natural Selection, is close to correct. It explains the evidence (which is that animals and plants change over time) that we see and makes successful predictions.
