I've read a lot about anti-matter, but I'm wondering how much power
develop when anti-matter and normal matter come together. Is it heavier
then a atomic bomb or less???????
The energy released when matter and antimatter meet is equivalent to the
total mass of the matter and antimatter (i.e., twice the mass of the matter).
Only a very small fraction of the matter in an atomic bomb is converted to
energy, so gram for gram, an atomic bomb is much much much less potent than a
matter/antimatter explosion. Of course, you don't normally see grams of
antimatter hanging around.
