Re: CMBR Dipole (2009 September 6)
If we are moving so fast, which I don't doubt by the way, why do other changes 'out there' take so long to reach us? I'm assuming it is because of the massive light distances between objects. But still, 600 km per second. 1,8921,600,000km per year. That must be pretty close to the speed of light? Ar...

Space debris?
G'day, I live in Ipswich, Australia. Tonight (28/07/09) I was returning from work and was traveling in a westerly (maybe WWS ish direction) and saw a bright flash out of the corner of my eye. When I looked I saw a fire trail and considered something had entered the atmosphere. It lasted half a secon...

Re: M13 Globular Cluster (APOD 2009 June 17)
Okay. In layman terms. Does anyone know how far apart the stars are in cluster? And do they orbit a a central object? Is the cluster expanding, compacting or static? I would assume that they don't move in opposition to each other? I started reading the replies but most of them went over my head.

What do you make of the CERN experiment?
"Superconducting magnets will then steer the counter-rotating beams so that strings of protons smash together in four huge laboratories, fleetingly replicating the conditions that prevailed at the "Big Bang" that created the Universe 13.7 billion years ago". What do you think the...

Following the thought chain of Makc, why does life have to meet our definition of life supporting physics and chemistry? I've often thought that just because we need this air mixture, gravity and certain density to live in, what makes us think that ALL life forms (if there are any) have to live in t...

Compact Galaxies
Found this on another site: The galaxies, each only 5,000 light-years across, are a fraction of the size of today's "grownup" galaxies but contain approximately the same number of stars. Each could fit inside the central hub of the Milky Way. "These ultra-dense galaxies, forming the b...
