Naming suggestions

I am a bit annoyed now, since NASA makes no mention of the naming suggestions sent in. They simply announce it is now called Fermi… Most of the sugestions sent in were probably Fermi (mine was…) but why not mention the whole suggestions-thing?

I heard from an insider that the most popular name submitted was "Satellite of Love". Bluethumb (talk) 19:36, 30 October 2008 (UTC)

   This NASA page's 5th- & 4th-to-last frames strongly suggest that the Lou Reed song's title was (at least temporarily) indeed in the lead.

   Actually (per the same source as in my response above to Bluethumb) "Fermi" ranked (at the same point in time) 16th -- and below 5 omitted suggestions that were perhaps libelous or indecent.

Under "Discoveries"

"The gamma-ray burst GRB 080916C ... emitting the initial gamma rays must have moved at 99.9999 percent the speed of light."

Gamma rays would ALWAYS move at c regardless of the frame in which they are measured.

Wow...This nonsense has been in the article for months now? How sad. Deleted.--76.167.77.165 (talk) 06:45, 4 November 2009 (UTC)

The quotation was garbled, as was the reference. The article here actually claims that the "gas bullets emitting the initial gamma rays" must have been moving at 99.9999% c. That is conceivable, though I'd maybe want to check a scientific publication to verify the journalist got it right.

But note also that even so, there is a legitimate question about the rest mass of the photon: is it truly 0? Rather like there used to be about the mass of the neutrino, which is now generally believed to be non-zero. According to the Particle Physics Data Group, the rest mass of the photon is now known to be <10^-18 eV, which is pretty small, but not zero. If the photon actually has a non-zero rest mass, then it would always travel at a little less than c, and we'd have to work over E-M theory. But Special Relativity and the structure of spacetime might remain intact. (I suppose we would have to find a new name for c, tho....)

I don't have time to fix up the article just now, but that seems to be the situation. Cheers, Wwheaton (talk) 00:53, 5 November 2009 (UTC)

Active galactic nuclei are "irresponsible"?

'irresponsible' implies agency - something that AGNs aren't typically understood to have. maybe a new heading is in order? —Preceding unsigned comment added by 203.214.159.21 (talk) 04:00, 22 September 2010 (UTC)

Terrestrial observations

In addition to observing distant objects, Fermi Gamma-ray Space Telescope has also observed terrestrial gamma ray flashes and made some discoveries. I wonder if we should add a paragraph about those discoveries too? --Artman40 (talk) 09:03, 7 December 2012 (UTC)

Proposed automatic updating of orbital elements

I've proposed that this article be included in a trial involving using a bot to update orbital elements automatically on a fortnightly basis. I've started a discussion at WikiProject Spaceflight regarding this article and nine others, and would welcome some input from the users involved in maintaining the pages in question. --W. D. Graham 20:59, 24 July 2013 (UTC)

What time and energy resolution

GBM says "... design is optimized for good resolution in time and photon energy." but no figures. - Is GBM or LAT able to detect dispersion as in pulsars and FRBs ? - Rod57 (talk) 14:09, 5 April 2015 (UTC)
