“1グラムで地球破壊” 超高エネルギーの「宇宙線」捉える
[ad_1]
宇宙から降り注ぐ小さな粒子「宇宙線」のうち、計算上、わずか1グラムで地球が破壊されるほどの巨大なエネルギーを持つものを発見したと、大阪公立大学などの国際研究グループが発表しました。観測史上2番目に高いエネルギーの「宇宙線」だということで、グループでは巨大な星が爆発するなどして発生した可能性があるとしています。

An international research group, including Osaka City University, has announced the discovery of tiny particles called "cosmic rays" with an immense amount of energy, enough to destroy the Earth with just 1 gram. This is said to be the second-highest energy cosmic ray in observational history. The group suggests that it may have been generated by events such as the explosion of a massive star.
