Starship Asterisk*

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...

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...

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.

I did see the other thread, after I had posted this. It was a spur of the moment thing after reading an article of supposed doomday results.

"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...

If the surface is constantly changing due to volcanic activity and the throwing up of lava. Does this mean that the moon is getting larger in circumference and more hollow under the surface?

But if it was beyond the universe, would it be in 'space' as we know it (a vaccuum)? Is that what is beyond our expanding universe?

More importantly, what is beyond the expanding universe??

On the subject of objects beyond Pluto, does anyone know much about the Kuiper Belt (supposed to contain another dwarf planet "Quaoar"), and beyond that "Sedna", another dwarf planet(?), and what about the Oort Cloud (how did it get that name?).

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...

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...

Do stars exist outside of galaxies? I've often wondered if stars are something that can exist in space outside of a galaxy, or do they have to be part of a galaxy?
