New supernova thrills astronomers and skywatchers around the world

The neutrinos from SN 1987a , after traveling over 100000 light years , were only delayed by seconds if at all. A neutrino can weigh no more than 1.1 electron volts (eV)—less than one-500,000th the mass of an electron. Since the energy of these neutrinos was in the millions of electron volts they had to be traveling very close to the speed of light to have that much energy. The models of supernovas predict 99% of the energy of the supernova is carried away by neutrinos.

It is my prediction that most of dark matter is merely neutrinos that have slowed down somehow. The universe pumps these particles out in huge amounts with almost nothing capable of removing them.

I hear wood chippers are good at removing pedophiles.

If we are in the path of a gamma ray burst we would be fried and that could be from stars thousands of light years away or even billions. ________________________ With a magnetic field hundreds of trillions times that of Earth, any living thing would be dead before it got to the magnetar's surface, because the magnetar would have the power to scramble every atom in a person's body. Even at a distance comparable to the half-way point between the Earth and the moon, a magnetar would be able to suck keys out of pockets. https://www.tampabay.com/archive/1998/09/30/distant-star-zapped-us-nasa-says/ _______________________ However, a sufficiently large gamma-ray burst could theoretically strip the planet of its atmosphere and cause a mass extinction event. Indeed, it is widely believes that a gamma-ray burst caused the Ordovician extinction roughly 443 million years ago. these bursts generate as as much energy as our sun will during its entire 10 billion year lifetime. On this recent occasion, the explosive event — now officially dubbed GRB 221009A — traveled roughly 1.9 billion light years to reach Earth https://www.salon.com/2022/10/18/a-gamma-ray-burst--possibly-the-brightest-of-all-time--sweeps-over-earth/
