Hubble Spots Source of Short Gamma Ray Burst

symbolset writes "Researchers using the Hubble Space Telescope have imaged some evidence that the merger of neutron stars is responsible for producing a short-duration gamma ray burst. On June 3rd the Swift gamma-ray burst (GRB) mission detected GRB 130603B, a burst lasting only one tenth of a second nearly 4 billion light-years away. Imaging with Hubble, they located a small red dot which, over the course of the following two weeks, dimmed."

Hawking Decay (1)

Anonymous Coward | about a year ago | (#44478173)

One possibility GRB source might be QBHs (small black holes created during the high pressure of gluon soup matter soon after the creation event). Most would have long decayed, but the estimate for their half life is usually massively underestimated because relativistic effects aren't considered. For some of these higher velocity boojums, the universe is probably not even a week old yet. They may be far more rare these days, but QBHs are going to be with us for a long time.

Spectra doesn't seem to match in some cases, though, so there are probably multiple causes for the various GRB events.

There is no practical method for these to form at relativistic speeds. They would need to be accelerated and doing so would violate C-P conservation.

tysonedwards (969693) | about a year ago | (#44478249)

In this case, the likely cause is two colliding white dwarf stars.

What "creation event"? That merger of the two neutron stars? Even that wouldn't have nearly the required amount of energy concentration to produce the small holes.

Re:Hawking Decay (1)

Teancum (67324) | about a year ago | (#44481161)

He is talking about the Big Bang. AKA the "creation event" as defined by current scientific cosmology. You may think this kind of cosmology is just as silly as other kinds of cosmology, but that is personal opinion and belief.

I would say that event has more than enough energy concentrated to produce small black holes. Likely a few rather large ones too.

Which Day of the Creation Event would that have been?

Btw for any geeks into solar weather......be sure to check out S0's daily 3 minute briefings on all things earth and solar weather related - http://www.youtube.com/user/Suspicious0bservers [youtube.com]

Re:S0 (5, Informative)

Teancum (67324) | about a year ago | (#44478607)

Sigh.

While this guy seems to occasionally spot something not typically mentioned by science reporters, and especially seems to spot solar flare and other solar activity based upon his monitoring of various solar observatories over the internet about as good as any space weather forecaster, he has some really silly ideas about the causal relationships between solar storms and geological activity here on the Earth that goes into what could charitably called fringe science.

If you really want to see some more reliable forecasts, I'd recommend instead the NOAA Space Weather Prediction Center [noaa.gov]

Still, this YouTube channel is at least worth an occasional chuckle or two. You certainly shouldn't take it too seriously.

Re:S0 (0)

Anonymous Coward | about a year ago | (#44479135)

I think S0 has been pretty upfront about his accuracy on Solar causality to predict earthquakes and as he publishes online in advance/arrears its easy to see his record.

Re:S0 (2)

Teancum (67324) | about a year ago | (#44479461)

Again, does he have any other substantial group in the scientific community that agrees with his theories?

I sort of thought so. That is sort of the definition of fringe science. He may be correct (sometimes fringe researchers hit upon a good idea that takes time to become accepted into mainstream science), but by far it is more likely that he is a loose cannon and drifting off into spouting off pure nonsense. He also tends to spout off some fringe political ideas in his videos too, which is something that seems to be a reason to question his reliability.

Like I said, use his information with a grain of salt. I did use one of his predictions to help see a real nice Aurora Borealis (aka Norther Lights). You can get a prediction for something like that from other sources, but he did seem to get the prediction a little bit earlier due to his watching sun spots like a hawk and suggested that such a solar flare might be coming.

There are more than 200 earthquakes per day that are large enough to be felt by humans.

Even Einstein would agree that it at least happened months ago.

Depends on which frame... for any frame roughly related to Earth's motion, it happened billions of years ago.

Pity that there wasn't a gravitational microlens somewhere along the way. We'd have a nice ancient dupe. ;/
