Blast from nowhere... GRB 070125

"Here we have this very bright burst, yet it's surrounded by darkness on all sides," said team member Brad Cenko of the California Institute of Technology. "The nearest galaxy is more than 88,000 light-years away, and there's almost no gas lying between the burst and Earth." Click HERE for the full story.

A mystery so far. But maybe not. The explosion was a long-duration gamma-ray burst (GRB) typically associated with the death of a massive star. But images taken after the burst faded showed no galaxy at or near the location. A "Dark Matter" burst?

I think we will find that all of this "missing" dark matter is not missing at all - we just cannot see these objects with our current telescope. My prediction is that once we have more powerful telescope in operation, we'll find that dark matter isn't dark or missing but merely too faint to be seen with our previous generations of telescope.

Considering that we're still surprised to find "faint" dwarf galaxies very near the Milky Way - and most of them by serendipitous activities at that. It should not surprise us then that we are not seeing that the universe is most likely flooded with matter (that is not missing) simply not shining or radiating bright enough for us to see at great intergalactic distances.

So, dark matter - perhaps an appropriate name - is most likely not missing at all and really no mystery at all.

This GRB probably occurred in a starburst region that may have been pulled away from a nearby galaxy gravitationally at some point in the dim past.
