The supernova may be bombarding Earth's atmosphere

Physicist Amir Siraj and Harvard University's Professor Abraham Loeb suspect that some space bullets may be attacking our atmosphere when traveling at 3,000 km / s.

Earth is being bombarded daily by cosmic bullets (meteorites) with a width of 1 mm - 10 cm and most of them fly into the atmosphere at a faster speed of 17km / sec. However, with supernova space bullets moving at a speed of 3000 km / sec, their destructive power will be dangerous to the earth and can instantly "evaporate" the spacecraft. .

The new study aims to understand one of the mysteries that are happening in astrophysics, about whether the supernova will shoot debris at a fraction of the speed of light and whether these cosmic bullets. will hit us or not.

They also suggest that cosmic bullets can be fired from supernovas, causing them to accelerate faster than normal. Although this theory has been proposed before, the search method is not accurate.

The two scientists developed a model to track the hot plasmas fired from these ultrafast meteorites as they collide into our atmosphere.

"We found that a relative cosmic bullet would produce shock waves that could be picked up by a microphone and also a visible ray of radiation in the optical wavelengths - both lasting about 1/10. of a millisecond. About 600 wave detectors are set up on a global network to perform this trick, " scientist Amir Siraj told Universe Today.
