Tracing the Universe’s Past With Neutrinos

When the universe formed via the Big Bang, around 13.8 billion years ago, slivers of its impression remained in the form of subatomic particles called neutrinos.

Scientists believe that neutrinos may hold the answer to how the universe looked like in its budding years. Many new theories may be derived from the recent discovery, which will separate neutrinos resulting from radioactive decay and the ones that originated from the Big Bang, also known as the neutrino background.

The tricky thing is that these neutrinos emit weak energy signals, hence, scientists are left to depend upon the study of its interaction within cosmic areas.
