Experimental Particle Astrophysics

科学家喜欢谜团，因为解开自然界的谜团意味着有机会了解宇宙的新事物。高能宇宙射线就是这样一个谜。外面有什么东西--没人知道是什么--正在宇宙中抛出令人难以置信的能量粒子。这些粒子是否来自某种未知的超强宇宙爆炸？从一个吸食恒星的巨大黑洞到它们的暴力死亡？来自相互碰撞的星系？来自宇宙起源的大量无形遗迹的坍塌？我们还不知道答案，但我们知道，解开这个谜团将使科学家在理解宇宙方面向前迈进一步。这个来自东北大学的小组希望成为解开这个谜团的团队中的一员。

Scientists love a mystery, because solving a mystery in nature means the opportunity to learn something new about the universe. High-energy cosmic rays are just such a mystery. Something out there -- no one knows what -- is hurling incredibly energetic particles around the universe. Do these particles come from some unknown superpowerful cosmic explosion? From a huge black hole sucking stars to their violent deaths? From colliding galaxies? From the collapse of massive invisible relics from the origin of the universe? We don't yet know the answers, but we do know that solving this mystery will take scientists another step forward in understanding the universe. This group from Northeastern University wants to be a part of the team that solves this mystery.
