yes, positrons were discovered in experiments in the 1930s just like theory had predicted. many other anti-particles have been discovered since.
In a literal sense no, but they have been detected experimentally. The fact that your television works is proof enough that electrons exist, since an electron is required to strike a screen in order to produce an image.
The field of chemistry searches for the proof, the whole proof, and nothing but the proof.
The safe was guaranteed to be fire proof. The only items left in the burned out store was the fire proof safe and walk in freezer.
Alcoholic proof is a measure of how much ethanol there is in an alcoholic drink.Spirits were tested with gunpowder.A mixture of water and alcohol proved itself when it could be poured on a small amount of gunpowder and still light up the wet powder. If the powder did not ignite, the mixture had too much water in it and the proof was considered low.A "proof spirit" is defined as 100 degrees proof (100°). This is the same as 57.15% ethanol.
No.
No, vampires dont exist and there is no proof and if there was it would be so cool
The James Randi Educational Foundation has offered a million dollar prize for proof of the paranormal.
There is no proof that ghosts exist. Until there is, they are not real. Ghost Buster
There is no scientific proof that ghosts exist but there are thousands of photographs(not to mention audio or video!):)
A contemporary example of an issue where scientist stand on one side and different groups stand in opposition is global warming. Many people claim that global warming does not even exist but most scientist have proof that it does exist.
people have proof that it use to exist but i doubt any one has that they have proof that they still live
possibly, there is little proof that he does and no proof that he doesnt
No. There is no proof of the existence of mermaids because they do not exist.
No, but most believers don't need proof.
