can someone explain anti-matter to me?

No better sensation that a biro on a banana.

I get physics

Well the same magnitude of mass, but it really has anti-mass being anti matter and all.

No such thing as anti-mass.

1kg of matter has 1kg of mass
1kg of antimatter has 1kg of mass

(they both bends spacetime by the correct amount for their mass)

1kg of matter + 1kg of anti matter = zero a lot of energy.. now do you get 2kg 8 c^2 or just 1kg * c^2 ?

I take it you meant 1kg of matter + 1kg of anti matter

You get 2kg x c^2 of energy. You’ve converted 2kg of matter into energy

Yes, edited.

Actually, I should edit out that whole question cos it’s rather stupidly obvious. And me with a Physics degree and everything.

You get 2kg x c^2 of energy. You’ve converted 2kg of matter into energy

And a very loud bang 😉

from that BBC link

Every member of the zoo of particles we know about

FFS – have they never heard of a quiver of particles ?
(couldn’t have a stable, obv 🙂 )

is anti matter still theoretical? Or scientifically measurable, quantifiable, observable fact?

Observable fact. it is used in PET scanning in medicine:

It’s not complicated folks.

The flying spaghetti monster keeps these in perfect balance with his noodley appendages.

whats the opposite of banana?

¿?u?u?q

Yes there is, writing on the sole of a slipper with a biro. Fact, arrived at after years of dedicated experimentation. 😀

Read a great book by Brian Cox – Why does E=mc2 (and why does it matter)
