Using a space telescope like Hubble (but others are more suited to searching for GRBs) to view distant objects like WR 104, we are effectively looking back through time.
If we see an object 8000 LY away, we are looking back through time to a period 8000 years ago. And since the light and other EM we can see using the scope is still visible, it means the star has yet to go super or hyper nova, as we see it.
The light or more importantly the radiation from that star, would take 8000 years to reach and threaten us, as it's still there and hasn't exploded yet (from our point of view, 8000 years away)
When talking about distances in terms of Light Years, you may as well think in terms of actual years.
At the speed of light, the GRB would not strike the Earth (even if we were unlucky enough to be in the path of it's focused beam) for 8000 years AFTER we see it explode.
I hope to not seem rude here, but that's not how it works. Gamma Rays travel at the speed of light too, so the moment we see it explode is the moment we get bathed in its radiation.

Really cool stuff Erik!! Love it.
This may be a dumb question, however I have to know.
Is it possible if and when this thing goes hyper-nova we may not get a direct blow but a glancing one to our Solar System? Is that scenario possible?

Worst case? Only microbes deep in the Earth will survive this.
Indications of WR 104 is that it is close to the end of it's life. They think that (from the 8000 year old light we are seeing) from what they are seeing, it will die very soon. Could be today or 100 years from now.
The weirdness, if you want to call it that, is the premise that the act of measurement of one actually defines both of them and so one might be thousands of miles away when you measure the first and the other instantly is converted, regardless of the distance between them, to the complement of the first. Action-at-a-distance that occurs faster than the speed of light?
In the weird world of quantum physics, two linked particles can share a single fate, even when they’re miles apart. Now, two physicists have mathematically described how this spooky effect, called entanglement, could also bind particles across time.

This thread made me think of an early warning sensor system for this type of event. First of all someone would need to invent a quantum entanglement communication device to instantly relay information. Then the sensors could be sent into deep space in strategic locations to give early warning back here on Earth. The distance in light minutes between Earth and the event would be the amount of warning potential in minutes. Even with an early warning, I don't know if a lot of lives could be saved by moving to the side of the planet not exposed or if the GRB event keeps shooting at us exposing both sides of the planet.
I've read or heard this type of event could have been the reason for mass extinctions in our past.
Of course inventing such a device and only having one working if it suddenly went dead could leave you wondering what happened to it or evacuating thousands because of a faulty device. I doubt millions could be saved but maybe our species could survive. I believe it takes about 50 years between a device being invented in the skunk works projects and the public hearing about it so maybe there are already some working devices. I'm speculating. There isn't much I can do but speculate about a GRB event.edit on 9/6/13 by orionthehunter because: (no reason given)edit on 9-6-2013 by Char-Lee because: (no reason given)extra DIV
