If you put 20 mirrors lined up with eachother on Mars to Earth back and forth what would you see?

A number of problems.\nMars and Earth rotate.. You couldn't line them up. However, as this is a theoretical question...\nSay it took two minutes for the light to travel from Earth to mars... \nTherefore if you had 20 mirrors you'd be looking at a 40 minute lag in what you see.\nTheoretically you'd be able to see a clock reflected so many times that it would be 40 minutes slower than it actually was but you'd need some damn good mirrors and damn good optical devices.\nHowever you could only see the light you trapped.. The light from the dinasaurs went away a long time ago.\nIn order to see that you'd have to get near to the edge of our known universe in an instant.. Not so easy.\nBy trying the experiment with the mirrors you'd be able actually to prove the speed of light.\nIt would be a pretty buzzy experiment to do though...

Much larger.  It is a gas planet, where Mars is a rock planet.

Maybe you could make use of a giant mirror orbiting directly above you geostationarily in space.\n\nSo you could see your house... from the sky. :)

It would appear as a dim ball revolving around itself and orbiting earth, phaes will not be visible of course, it will look like a ball all the time to an observer flying near by it in space.

MARS... quite possible

How would a tourist from mars relate his experiences on earth when he gets back home

Because the Earth is round, the widest point could be from top to bottom.... it all depends on which way you are looking at it.

When a mirror is hit by particles of light called photons, it reflects the photons back to us. When photons hit a smooth surface like a mirror, they bounce back off of the mirror at roughly the same angle at which they hit the object, creating a reflection that looks the same.

I think youd see a new planet ;)

mercury, mars, venus, earth, jupiter, saturn, uranus, pluto and neptune.

Infinite, look at the stars. Through the earth's atmosphere one can only see approx 60 miles on a clear day.

It will be from way out on a plane based on our orbital track. I think the intensity of the sun will block out the view of whether or not it goes behind or in front of the sun. The center of the universe, even though it is a non-existent place, for arguments sake, would be moving as everything in the universe is dynamic. (There is no end to infinite, therefore the center cannot be defined.)

The Earth and Mars do not orbit the sun in perfect circles, they are ellipses.\nSo sometimes the Earth is closer to the sun than other times, and sometimes Mars is closer to the sun than other times.\nSo if the Earth is farther from the sun than normal at the same time Mars is closest to the sun, and this happens when both planets are on the same side of the sun, then we are closer to Mars than any other time and therefore we can see it better.

Well, Idspudnik I don't know what you seen but there is being visiting this earth some are "Angels" and some are being from other star constellations We are not alone! But it funny you mention Ezekiel wheel....now think hard if you and I seen Ezekiel wheel we would run and say that a @#$%^&* UFO...right? But Ezekiel would say stop running those are the Gods....Now think on that....

well actually, it depends where you are on the moon.\nIf you are on the back side, away from earth, you will never see the earth, since that side never faces earth. you would need to walk? drive? around to the side that does face earth, and then yes, you could watch the entire earth sping by, once every 24 earth hours.

It actually depends on how far Mars is from Earth at the time you decide to travel. According to http://www.uwgb.edu/dutchs/planets/mars.htm \n\nThe Earth-Mars distance varies between 36 million miles and 250 million miles. That means that your travel time would range from 450000 hours (51 years) to 3125000 hours (357 years)\n\nNote that this estimation does not take into account the fact that Earth and Mars are continually in motion. If, as you drive, you are constantly pointing towards Mars, you wont be moving in a straight line, and the time of travel will be much longer. In order for the above estimations to hold, one would need to try to intercept Mars' trajectory...

Debatable. It does just look like a bunch of rocks...what is stranger though, is why NASA keeps doctoring the raw images before releasing them to the public? A good example of this is the 'true' colour of mars. It's not a 'Red Planet' at all-it has a blue sky for one and why are some things masked over? Hmm...
