pretty much star gets wayyy to big explodes releases tons and tons of unstoppable energy from the stars poles. Energy needs a hugh object to abosrb the energy. energy wants to go to earth. ozone destroyed organisms dissapte. 80 t 90% of the earths pop is screwed like kim kardashian
it happened a few years ago and nasa said that u could put all the stars in the universe and blow them up and it would still not be as strong as what they found it also proved e=mc2 to be WRONG
@steamingpoopfart That's nonsense. While GRBs are one of the most energetic events we've observed, it's false that they're brighter (or more energetic) than all the stars in the universe. In fact, for some time astrophysicists miscalculated their energy because they assumed they were spherical "explosions", but it turns out they're strongly beamed along one direction. This means they're not as energetic as previously thought. And just HOW it proved E=mc^2 wrong??
It was on the science channel they had a whole show about it it happend back in 2003 and it wouldent stop for 2 months some thought the universe was ending.
@meithan Very true, but now they know it is channelled it meaning one occurring from within our galaxy could fry our planet if it directly hit us. How close in our galaxy I am not sure, can't remember lol
@ProjectVRD A recent research paper estimated that a gamma-ray burst, pointed at us from a distance around 1 kpc (~3200 light-years), could cause a major depletion of the ozone layer, which would in turn allow a dangerous amount of UV radiation to reach the surface and have a severe impact on life globally. Fortunately, the rate of gamma-ray bursts is low enough so that they expect such event to happen about once every billion years. So we shouldn't worry too much.
isnt there a neutron star in a death spin with another called the reyet or something like that that most likely will make a GRB pointed right at us about 8000 light years away
If one ever hit us, the atmosphere will take the hit for us. But half of the ozone will be destroyed and the atmosphere will have gases such as NO, NO2, N2O, and N2O3, that will block out 10 % of the sunlight.
a gamma ray burst near our solar system is hypothesized to be worse than a nova of equal distance as far as radiation is concerned. Our atmosphere can only handle so much.
I found out a mabey a year or so ago that they are emitted from star quakes on Magnetars and from Quasars and Blazars as well. A GRB (in this case a flare from a Magnetar) in December of 2004, from 30,000 light years away breifly altered the upper atmosphere of the earth.
Gamma Ray Bursts were accidentally observed by the US Vela spy satellites in the 1960s but this discovery wasn't declassified until 1973. Nowadays, scientific satellites such as SWIFT point out that GRBs are linked to supernovae and neutron stars!

i like how the animation was done on this video it resemble what a gamma ray burst might look like

I wouldn't go so far as to say 'most likely,' but yeah, something like that.

A hypernova is when a very massive star more than 30 times the mass of the sun burns all its fuel into iron, then It turns into a black hole.

Dog I think we can survive that because we're human's. We're powerful.

GRB are the biggest explosions in the universe they make supernovas look
like little white dwarf flashing.

wrong there would be life in micro bacteria beneath the soil of the earth... life would adapt.

If a GRB happens about 3000 light years away it's enough too kill every living thing on earth.
If earth got direct hit by a GRB it would make the atmosphere catch on fire and firballs and acid would rain from the sky....

Very interesting. There's also an episode on Mega Disasters on gama ray bursts.

I just saw an episode on the universe about GRBs very interesting, but i hope we never get hit by one that would suck to the max.

Earth is always getting hit by GRB's but the stars that can cause sever damage and many many light years away

Neutron Stars aren't the only theory to GRBs. Astronomers are also saying the Gamma Ray Bursts are emiited from Hypernova's as well.

correct spy satellites picked up nuclear radiation coming from space wich is how they discovered grbs
