RE: A breakthrough in astrophysics - observation of a first powerful engine to accelerate cosmic rays

in #steemstem • 6 years ago

I read about this a few days ago in the science news. I knew one of you guys would communicate this one to the local stem community.

By the way, is there any information on the time dilation for a neutrino such as this? It traveled 3.7 billion light years, but to the neutrino was it only a few minutes of travel time?

    Time dilation is huge here, as neutrino travels very close to the speed of light (they are almost massless and the dilatation is infinite in the massless case). I don't have the exact numbers however.
