AI Thread Summary
A significant cosmic explosion occurred on December 27, 2004, approximately 50,000 light-years away, initially thought to be a natural cosmic event. Some speculated it was caused by a Type III civilization attempting to access hyperspace using immense energy. However, NASA clarified that the explosion was actually a giant flare from a magnetar, specifically SGR 1806-20, a type of neutron star with a strong magnetic field. This flare was the brightest recorded, surpassing all historical star explosions, and emitted primarily in the gamma-ray spectrum. The consensus among scientists is that the explosion was not linked to any advanced civilization.

i was searching for the exact specifics of a type III civilization

when i came across this serious news artical

http://www.indiadaily.com/editorial/6598.asp"

Its about a great explosion which happened approximately 50,000 light-years away
On Dec 27 2004.

I do recommend reading it

here are some excerts from the news report

"When Earth saw the strongest ever flash of light from a short explosion 50,000 light years away, scientists first thought it was a cosmic explosion in the natural way. But now many scientists believe it came from a type III civilization that is trying break the barrier of space and type by using huge amount of energy."

"According to scientists, this was an experiment by a type III civilization trying to break open into the Hyperspace with the help of enormous amount of energy."

Funny that they never mention which scientists in particular are making these speculations!

I remember reading about this blast -- it was referred to as a Soft Gamma Ray repeater, and NASA gave this explanation:
http://www.nasa.gov/vision/universe/watchtheskies/swift_nsu_0205.html
The scientists said the light came from a "giant flare" on the surface of an exotic neutron star, called a magnetar. The apparent magnitude was brighter than a full moon and all historical star explosions. The light was brightest in the gamma-ray energy range, far more energetic than visible light or X-rays and invisible to our eyes.
 
The flare was from what is known as a Soft Gamma-Ray Repeater and the object was SGR 1806-20. The physical interpretation of the system is that it is a magnetar -- a young neutron star with an extremely strong magnetic field. The object was (and still is) detected in many different wavebands, even showing a steady pulsation in the X-rays. It was not from a Type III civilization.

EDIT: Ah, MIH beat me to it. :)
 
Hmm, not bad for an information scientist type . . .
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
