What would happen if a gamma ray burst from a supernova hit Earth from differing distances?
If a gamma ray burst hit the Earth, would humans go extinct?
When are gamma rays considered dangerous? What are the various dangers of gamma rays? What would cause sudden emissions of gamma ray's randomly? What are gamma rays? Why are they dangerous? Do radioactive decay and gamma rays affect the electricity? How and why? Which species would take over the world if humans went extinct? How are gamma rays produced? What would happen if humans go extinct before other species? What would happen if a very powerful Solar Flare or CME hit the Earth? What would happen if a neutron star collides with earth? When gamma radiation is emitted, is the energy released to bring the nucleus to a lower energy state or is there a mass decrease in the nucleus to release energy because of e=mc^2? What are gamma rays? How are they produced? What would happen if a neutron star collided with Earth? The redshift of a gamma-ray burst object shows a distance of about 12 billion lightyears. How close was the object when the burst occurred? Did we humans ever come close to an event that would cause mass extinction of life on Earth, natural or man-made? Are there any potential supernovae close enough to impact life on earth if they explode? If the Earth gets blasted by neutrons from space would that set off all nuclear weapons? Since some gamma and cosmic rays pass through our atmosphere could we take advantage of their penetration power and get an image of the subsurface with them? What chain of events would happen if the sun expired and exploded? Have Comets, Asteroids and Meteors all caused mass extinctions? If I was an alien who wanted to kill humans by irradiating the earth. What kind of (real world) radiation should I use and what would humans notice? Hypothetical scenarios: What would happen if humans disappeared from Earth? What are gamma waves as produced by the human brain? Is it possible that Hawking radiation is matter broken down into protons, electrons, and neutrons and then released back into the universe as energy? Will a person be harmed if he/she goes within 1Km of a neutron star? Which species has the best chance to become sentient if humans go extinct? What would happen if humans still existed when the Sun starts to age into a red giant? Could planet 9 have cosmic ray lightning? What if, 65 million years ago, the asteroid didn't hit Earth and the dinosaur extinction didn't happen? Will humans go extinct if all other animals die?
