SGR 1806-20 provided "enough energy in .2 seconds than our sun provides in 100, 000 to 200,000 years" (I don't remember the site that these figures are from... sorry) -- Since black holes bend light, wouldn't that mean that the light ( gamma radiation or whatever) from something so powerful, which goes out in all directions from it's origin, would not only be seen from earth directly (56,000 years after it left the former neutron star) but would echo throughout the universe for a while as it's hurled back and forth by things like black holes? If so, would we be able to pinpoint the locations of these black holes? Also, if the expansion of the universe is slower than the speed of light, and light has physical properties (I think) then: 1. all light generated since the big- bang is waaaay out there - rediculously beyond even the outermost particles of matter (forever)? and 2. Does this mean that the size of our universe is measured by it's farthest light (from end to end)? Sorry if I've gone overboard with my question.
Re: Did/will the light from SGR 1806-20's death reach us more than once?
