Yes.
If we could communicate with intelligent life in a distant galaxy composed completely of anti-matter, we would have no way of determining that fact. No matter what experiment we asked them to perform, their results would be identical to the results we see in our galaxy composed of matter.
Yes, antimatter follows the same laws of physics as matter. Both matter and antimatter are subject to the fundamental forces and interactions described by the laws of physics, such as gravity, electromagnetism, and the weak and strong nuclear forces. However, antimatter particles have opposite charge and other properties compared to their matter counterparts.
No. The known laws assume that matter can't be created nor destroyed.
No they can't
They would annihilate each other equally. Every electron that encounters a positron (the antimatter equivelant to an electron), every proton that encounters an antiproton and every neutron that encounters an anti-neutron would completely annihilate; both the matter and antimatter particle would fully transform into energy with no residual matter (nor antimatter) if the touch were somehow perfect.The amount of energy produced is enormous for even a small amount of matter/antimatter annihilation. The amount of energy released is dependent on how much matter and antimatter annihilate each other based on Einstein's famouse equation, e = mc2, which means energy (e) is equal to mass (m) times the square of the speed of light (c). Since light is incredibly fast, squaring it is a huge multiplier to mass. Nuclear fission (atomic bombs) and nuclear fusion (hydrogen bombs) generate their energy based on this same formula, but only a relatively small amount of the matter used in fission or fusion is converted into energy. By comparison, all of the matter and antimatter that come into contact will convert into energy, so the power of an explosion resulting from a matter/antimatter annihilation would be many times more energetic than even a hydrogen bomb of similar mass.The largest bomb ever detonated in the history of manking was the Tsar Bomba, a fusion or h-bomb which yielded an explosive force of 50 million tonnes of TNT. The bomb itself weighed 27,000 kilograms.By comparison, if you had a combined total of 27,000 kilograms of matter and antimatter, and created an annihilation bomb (putting all of the matter and antimatter into contact with each other), the resulting explosion would be1,159,920 megatonnes (or 1.15992 teratonnes) or more than twenty-three thousand times as powerful as the Tsar Bomba! This is huge, but wouldn't quite destroy the earth though it could certainly exterminate a lot of life. The "dinosaur killer" asteroid, estimated to have been maybe 15 kilometers across and striking the earth at 20 km/s, was more than four thousand times as powerful as this.
With each new discovery in Physics there is a small rewrite of the laws of Physics. The Scientific Method used by Physicists and others means that to make a major rewrite of the Laws of Physics would involve a major discovery in physics being proven by more than just the discoverer
Absolutely. There's no doubt about that at all. They definitely did.We're just not completely sure of what the laws of Physics are under those conditions.
No, and antimatter apple would not fall up. It still applies to the same laws of physics, but the only variation is is when it makes connection with it's opposite charge, then the antimatter annihilates both itself and the particles that I connected to.
Physics
Yes.
No
Nothing would exist, physics is responsible for matter taking shape. If there was no physics, the atomic make-up of all matter would break apart and the universe would itself would probably do the same.
No. The known laws assume that matter can't be created nor destroyed.
No they can't
Both are branches of Physics: Kinematics is the study motion, Particle Physics is the study of matter.
The study of matter in motion is commonly called kinematics.
Paul Dirac thought it up in providing a mathematical theory uniting Quantum and Relativity Theory. The solution involved an equation indicating 2 values for the electron charge, minus and plus. This is an example of mathematics leading Physics. Physicists searched for and found the positive electron. See the link below for the whole story: http://livefromcern.web.cern.ch/livefromcern/antimatter/history/AM-history00.html Mathematics is not just a tool of physics it is often the microscope into unseen parts of Nature. The laws of Physics are consistent with Group Theory. This alone would imply the existence of antimatter particles as part of the "matter group".
