Taken my a martian? We want to believe--but those martians" cameras have crappy resolution.

A rough idea of the scale involved:

The hypothetical alien mapping mission of this galaxy uses ships that can travel instantaneously between solar systems. No warp factor 9.9 stuff here, we`re talking instant travel over any distance.

So they only use time investigating each solar system.

They`re only doing a really superficial survey, so extremely superficial that they only spend one day in each solar system. Just one day to survey an entire solar system.

It would still take 273,792,574 ship-years. Even with a fleet of 1000 ships all doing only this survey mission every single day and with perfect efficiency, the survey would take almost 274000 years.

So how likely would it be that they happened to be around here so recently that our technology was advanced enough to detect on a brief survey of our solar system?

Left quietly after putting up a warning sign for others :)

They`d have to be incredibly advanced to find us, except by chance. Even if they were advanced enough for interstellar travel to be routine for them, how would they find us otherwise? There`s absolutely no sign of us more than a tiny distance out from Earth and even that sign is extremely faint unless you`re more or less here already. Even if they have a fleet of ships exploring, it would take eons to cover everywhere. Even if they had passed by Earth on their grand mapping mission, chances are it would have happened long before any human technology they could detect existed. A quick scan on the way past...nothing interesting there, on to the next planet.

[quote]There`s really not much basis for that statement, not to be argumentative, but we don`t know what is out there or if it`s more advanced than we are ... so "marvels" may not be the best word, but in our own right we`re definitely advanced[/quote]

Same answer as before, really. It doesn`t matter if there are more advanced people elsewhere, or even if they come here. We`re still marvels. The pinnacle of billions of years of change. The ape that asks everything and finds answers.

(same with time travel, if it was possible then someone in the future who invented it would come back and say hi :P)

the real question is, are we among the most advanced beings in the universe? we always seem to think aliens would be more advanced but maybe we are not far behind, or not behind at all...

im just sayin.. cuz i think aliens would be more advanced seein as how they have ufos and lazer beams that can destroy entire planets.

[quote]Makes you feel kinda small don`t it?[/quote]

No. I`m still me, regardless of the size of the universe.

If you`re thinking in terms of the whole of humanity being small because we`re all on one medium-sized planet orbiting a medium-sized star in nowhere important...it was humans who put that camera way out there to take that photo. Humans, with their brilliant minds and dextrous hands. Humans are marvels of the universe.

Regarding a terraformed Mars:

i) How are you going to keep a created Earthlike atmosphere on the planet, given the low gravity and lack of a natural magnetic shield?

ii) How are you going to handle protection from the solar wind, given that Mars doesn`t have a natural magnetic shield?

You`d need to build in some way to artificially maintain Mars in a terraformed state. It would have to be part planet, part space spation.

[quote] Here`s a hint to its likelihood: we can`t even `terraform` our own deserts, which already have air, water, bacteria, microbial life, access to transportation for resupply, etc - and people think we can do it somewhere like Mars? It ain`t gonna happen. Ever. Its another "wish life was better somewhere else" dream. [/quote]

You must be one of those life-sucks people.

Just cause` its hard, doesn`t mean it will never happen.

FYI: There`s an image called "The Pale Blue Dot" that was taken by the Galileo space probe, out near the orbit of Pluto; it is the most distant image of earth that exists, from over 3 billion miles away.

You might be right, but your argument isn`t. There are big differences between turning a desert into fertile soil and terraforming a planet - the latter is not simply a bigger and more difficult version of the former.

Making another planet partially habitable could be easier, although the timescale would be centuries at least, probably millenia.

Terraforming Mars might just be possible in the future - a runaway greenhouse effect would go a long way to making it habitable over a couple of millenia. It would take a lot of maintainence though - gravity too small, magnetic field too small. Mars would be part planet, part spa

I just got home after an awesome party and I looked at this and got seriously disoriented.

and people will suffocate if they travel more than 30mph.

Come on, the ancient Mayans irrigated the desert, and the Saudis do a pretty good job now (so does the Nile). It`s just too expensive or hard to find the water. What if we crash an ice comet into Mars and seed the whole place with a bunch of chemolithotrophic bacteria to start the soil going, followed by some CO2 excreting and nitrogen fixing bacteria too (not sure where the N2 will come from), followed by some nice photosynthetic bacteria to make some O2. Ok maybe in 1000 years. 5h1t, Israel and Iran have nukes. Maybe never.

Because you`re far more likely to die from a virus than hit by meteorite.

Sadly Terra forming mars is just science fiction.At least until we invent a way. We cant yet because Mars doesnt have a magnetic field. The only way we could terra form Mars is if we found a way to re magnetize it.

I guess Hawking is correct when he says in order for us to grow and survive as a species, we must venture into space.

If when you stop and deeply think about where the edge of the universe is and you become completely awed, you can then start the think about being a genius or not. Thinking about this will now ruin the rest of my day, thanks a lot IAB...ugh...

No need to freak out people. The universe is probably infinite.And according to some scientists there might be an infinite number of other universes.

Found this on wikipedia

"To improve the quality of television pictures from the Moon, a color camera was carried on Apollo 12 (unlike the monochrome camera that was used on Apollo 11). Unfortunately, when Bean carried the camera to the place near the lunar module where it was to be set up, he inadvertently pointed it directly into the Sun, destroying the vidicon tube. Television coverage of this mission was thus terminated almost immediately.[8]"
