It is said that traveling at the speed of light will stop time. Which i disagree with since speed is a measurement of distance per unit of time. How is this possible?

Seriously, the Cassini Probe is taking hundreds and hundreds of pictures, every day, and yet there are only a few images being released months apart?
Interplanetary space isn't top secret or classified material. Why the hold up?

A neutrom has mass, it has a dimension, therefore it must have a surface. What color would a neutron surface have? A large number of neutrons make a neutron star. How would that surface look to an observer? What color would the nutron star have? Does the word color have any meaning in subatomic physics?

Time dilation is the phenomenon whereby an observer finds that another's clock which is physically identical to their own is ticking at a slower rate as measured by their own clock. (wikipedia).

Essentially, a clock on the surface of the earth will go slightly slower than a clock on the moon where there is less gravity.

What I don't understand is how a black hole can collapse to an almost infinitely small mass when the time dilation would become increasingly high. I mean wouldn't time go so slow that matter falling in would completely stop?? Would an object falling in ever find the center before the end of the universe?

It seems like the only good way to get to Mars and the moon and start colonizing right away to me. For those of you who do not know what project Orion was:

http://en.wikipedia.org/wiki/project_ori...

A 1950's project of using nukes for space propulsion.

It was not used due to the cold war and the tensions it would cause. The secondary reason is fallout. However, my reasoning is as follows: If you launch just 2 of these vehicles, you have all the material to start independence from earth and colonization activities in space…so…the amount of fallout from just two vehicles…would just amount to a few nukes…which have been dropped throughout the 20th century….

This would not put that much extra radiation into the environment, but supply enough of a payload to start large-scale activities in space…catch my drift? It may even cost less than slowly putting material through hundreds of rockets…

Truly advanced civilizations would have unravelled the mysteries of quantum physics and communicate over that medium, not using primitive radio signals. The chances that we would happen to catch another civilization which happens to be in the few hundred years of their evolution where they are using radio signals are very slim indeed.

No wonder we hear nothing. If we had a device however that could hear transmissions over the quantum medium, we would likely hear endless chatter and be able to watch alien TV shows.

Thoughts?
