LOL-BA: “Looking good, at GLAST!”

Old traveller, gamma ray,
Knock on hard, don’t be shy,
Stop at last
in our GLAST,
Whence we see you in our sky.

Astronomers never seen on the street???

I watched a PBS show with a sidewalk astronomer - grabbing people on the street and saying take a look at the sky, use my telescope.

I wonder what sort of mysteries GLAST will uncover in it’s career?

Imagine the insights into GRBs it’ll give!

BTW, can it also look into the galatic center?

If astronomers are never seen on the street, how do they get from place to place without getting run over? *wry grin*

Please, support your local astronomer. Give them one of those bright orange reflective triangles - let’s avoid astronomer collisions!

violations of Lorentz invariance

Um, wasn’t that possibility dead in the water as soon as the GZK cutoff was independently confirmed last year? At least DSR posited higher energy rays to violate (and be evidence for violation of) Lorentz invariance.

FWIW, I don’t see how Lorentz invariance can be violated on any scale and still give us a consistent physics. I believe DSR tried to make Planck scale some sort of cutoff - but that won’t work either AFAIU.

It sure is fantastic living in an age when I can pop onto the internet anywhere I go, at any time of day, and there will always be news of exciting innovation and discovery. Thanks for being curious, humanity!
