这是真的，当物质和反物质相遇时，它们会在大爆炸相互湮灭，然后把它们的质量转换为能量。
It's true that when matter and antimatter meet, they do annihilate in a big explosion and convert their mass to energy.
当一小块反物质击打天文台并与“正常”的物质相碰撞时，两个粒子都立即湮灭，并转变为伽马射线-费米就可以检测到它。
When a piece of antimatter strikes the observatory and collides with "normal" matter, both particles immediately annihilate and are transformed into gamma rays - which Fermi can detect.
当物质和反物质相遇时，它们就会自动湮灭，并在强大的爆炸中把它们的质量转换成能量。
When matter and antimatter meet, they annihilate, converting their mass into energy in a powerful explosion.
人们认为137亿年前在创造宇宙时所发生的大爆炸所产生物质和反物质是等量的，因此它们应该全部地彼此相互湮灭，所遗留下来的宇宙应该什么也没有。
The Big Bang that created the cosmos 13.7 billion years ago should have produced equal parts matter and antimatter, which would have annihilated, leaving the universe barren of either.
反物质极不稳定，当与物质接触时，会迸发出湮灭一切的能量。
Antimatter is very unstable and when in contact with the material, it will burst out of all the energy of annihilation.
