What if the Sun EXPLODED?

Because Science2 minutes read

Supernovas occur every 50-100 years in the Milky Way, with neutrinos carrying 99% of the event's energy; if our sun went supernova, Earth would be vaporized by ghostly neutrinos before any light reached us.

Insights

  • Neutrinos, created during a star's collapse, carry 99% of a supernova's energy and are weakly interacting particles that can pass through matter without impact, posing a significant threat during a supernova event.
  • The novae equation can calculate the energy deposited into a human volume during a supernova, revealing a lethal dose of radiation, highlighting the potential catastrophic consequences of a supernova event, such as the sun going supernova and vaporizing everything on Earth before any light reaches us.

Supernova Neutrinos: Silent Apocalypse from Sun

  • Every 50 to 100 years, a star in the Milky Way explodes in a supernova, outshining all other stars combined for weeks to months.
  • Our sun, though it will expand into a red giant, is not heavy enough to go supernova; it would need 10 to 100 times its current mass.
  • The process of a star dying involves burning heavier elements like carbon, neon, and oxygen until iron accumulates in the core, leading to a collapse.
  • Neutrinos, electrically neutral particles, are created in massive quantities during a star's collapse, carrying 99% of a supernova's energy.
  • Neutrinos are extremely weakly interacting particles, passing through matter without impact due to their minuscule effective collision area.
  • The IceCube Neutrino Observatory in the South Pole uses a cubic kilometer of ice to detect neutrinos, which are otherwise hard to detect.
  • During a supernova, the neutrino flux from the sun increases drastically, with higher energy and impact area, posing a lethal threat to life on Earth.
  • An equation, the novae equation, calculates the energy deposited into a human volume during a supernova, revealing a lethal dose of radiation.
  • If the sun went supernova, the ghostly neutrinos would vaporize everything on Earth before any light from the explosion reached us, leading to a silent apocalypse.
