Antimatter caught for even longer
A group of scientists have managed to trap antimatter for up to 15 minutes. This should allow them to study it in greater detail.
Of course, why would somebody WANT to study something that doesn’t last very long? Well, just about everything in this universe is made of matter and not anti-matter, so the main question is “Why is this the case?” Another question is “Do the laws of physics as we know them apply differently to anti-matter?” For instance, the graviton has not been experimentally proven to exist – but if it does, then what does the anti-graviton do in this universe? Repel objects instead of attract them? Although off the top of my head, that would require negative mass, as gravity is an attractive force between two masses – and physicists HATE negative mass. THis isn’t just an arbitrary decision, it’s because when if the mass squared (m^2) is negative, then the mass is imaginary – which really makes no sense whatsoever.
Unless, of course, you’re a mathematician. But they’re not physicists – or engineers. :p
