Please tell me where they got a shot like that of the milky way galaxy.

That's not the milky way... it just looks like it.... and is good enough for a reference to where we might be in our own galaxy...

Right, It's NOT the Milky Way and Probably not even a Good reference as to where we are actually located in our Galaxy, Just a Hypothetical Rendering of the Human species on a Planet in a Galaxy, with much to be Discovered.

Sorry for the Lame reference attempt!:

Heck, we have been going into space for a half a century now, and have only ventured to our nearest neighbor (the moon) a handful of times (in person). Exoloring the galaxy is a long way off. There is a lot of talk about colonizing Mars someday, but to be realistic, that would take a massive human effort far beyond anything ever attempted. The cost of sending just a single crew to mars would be in the hundreds of billions of dollars. On top of that you have the extreme distances and slow travel speeds. It looks to me as though small, relatively inexpensive probes are going to have to do the job for a long time to come.

What we really need is a Henry Ford for space travel. Can you imagine thousands of little mass-produced Model T space probes fanning out across the galaxy, searching for little green men and planets suitable for colonizing?<lol>

I think that we may see some exploration of our own solar system in our lifetimes, but that any colonization or galactic eploration is hundreds if not thousands of years away...if we last that long.

S@H got your computer running a little hot? Try my watercooling solution!

True, and when you take into account the theoretical limit to velocity, things look even more bleak.

I don't think we'll ever colonise Mars. The planet is too small and doesn't retain a high enoigh atmospheric pressure for unprotected humans.

Venus is to my mind a better bet. Very hot at the moment, yes, but at least it has sufficient gravity to retain a decent atmosphere. A bit of teraforming and Bob's yer uncle! Things would probably be a bit warm at the equator, but closer to the poles there would have to be an optimum climate.

A for colonising an alien planet, let's get to venus first......

I would have to agree with you. The cost of visiting venus is within our grasp, but the cost of terraforming and colonization would be astronomical (no pun intended). The biggest roadblock to colonizing any planet would be the prohibitive cost of space travel. Even if we did colonize another planet, that would do nothing to alleviate the population problem on this one. We would just make more babies.

Venus... still needs a lot of fuel to get to because of the difference in orbital speed.

I think an interesting probe could be made that would simply just float in the atmosphere at the right place in the temperature and pressure gradient. Perhaps even colonies could be built in this floating environment one day, though the view might be boring. Certainly good for getting around and studying the atmosphere and surface from a safe but closer distance.

I agree but we seem tobe back to an earlier thread
we need to get away from rockets and find a better fuel system
as the man said we are syill in the tin lizzie age

The methods described there could be used to propel a rocket without using any fuel.

I've mentioned this one before but it was quite a while ago so..
_experiments_

This guys web page has small models demonstrating electro/magnetic propulsive reaction, it works within the atmosphere [air pressure etc] but the effect declines when run in a vacuum... however this may be the case until all particles are removed by a high vacuum... as a low pressure partial vacuum causes corona discharge to happen..................... just thought of something that may alter this.

I am not yet sure if it works in true vacuum. [outer space]

also not sure if it needs the earths magnetic field to work??,...some sort of localised effect when confined within a larger field etc..?

still testing...

what do you folk think.

Explanation: What does our Milky Way Galaxy look like from afar?
Since we are stuck inside, and since opaque dust truncates our view in visible light, nobody knows for sure.

Cool Link Misfit,,,

Oh, Yea. I Herd You got stuck with the Blame!

We do have a better way. It's based on an 'external combustion engine' concept first thought up in the 1950's.

http://=http://www.daviddarling.info/encyclopedia/O/OrionProj.html

http://=http://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29

The problem is political, not the science or even the engineering. Mass media hype over the last 50 years has led to the current state of public ignorance, stupidity and paranoia against anything with the word 'nuclear' in the title.

I once had a 'conversation' with an college educated individual who claimed to be a 'green activist'. When I told her about the unshielded nuclear reactor in the sky (1) that is not only a proven cause of wild-wide skin cancers but that last summer was responsible for the heat death of thousands of old people in Paris France, she was 100% sure it had to be shut down 'right now' whatever the cost. She also claimed it was a 'known fact' that 'millions' had been killed by the "Melt Down" at Three Mile Island (2) and '10's of millions' by the Chernobyl "Explosion" (3).

The future of the human race (in space) is now in the hands of the Chinese ...

(1) it's called 'the sun' ...
(2) "the projected number of excess fatal cancers due to the accident ... is approximately one" (see http://=http://en.wikipedia.org/wiki/Three_Mile_Island )
(3) so far, 56 people have died as a direct result of Chernobyl. It was estimated that an excess of 9,000 deaths (in the 6.6 million exposed individuals) 'might be expected', but so far (20 years later) there has been no evidence of ANY excess deaths .... (see http://=http://en.wikipedia.org/wiki/Chernobyl_accident )
