Default IF you were on a space ship travelling the speed of light? 10 POINTS!!!?

How long would it take you to go to Saturn? Jupiter? Uranus? Neptune? Pluto? 10 points to whoever answers all correctly.
How long would it take to get to all those planets right now in the month of july?

The correct answer according to Albert Einstein is that at the speed of light the mass of any matter turns infinity. But logically to say the exact time for you to go there is the same time it would take light to reach there....

well, because the Earth is in constant motion, not only revolving once a day but also traveling through an elliptical orbit at thousands of miles an hour, as are the other planets, the farthest-out ones having the biggest orbits, there is no "one" distance that you can measure between Earth and those other planets. even NASA has the estimate of over a year to get to Mars, based on the reason I just explained: Earth will be 'chasing' Mars for most of that time (based on a vehicle moving at about 20,000mph).

To do what you're asking, one would have to pick an arbitrary point in time, probably when Earth and the planet of your choice are closest together, then freeze them stock-still in their orbits...but the universe doesn't work that way. So, you'll have to rephrase your question more precisely and give precise "ingredients" in your hypothetical example so that we know what our baseline/starting point is.

see what I'm saying? Saturn is not one fixed, set, unchanged distance away from Earth, they are both in constant motion at varying distances from each other.

Well I have a space time machine. I hop in it, select my destination, then click a button. I do sell rides for a minimal fee. It seats 4 there is an inflight movie and we have the best crablegs this side of the moon.

there's a wonderful site that shows you exactly how far away the planets are now.

http://www.fourmilab.ch/cgi-bin/Solar

go there.

Things you need to bring with you:

a calculator.
1 AU = 93,000,000 miles.
c (speed of light) = 186,000 miles/second.

what you will find:

Jupiter 4.16 AU (just about as close as it ever gets to us)
Saturn 9.97 AU
Uranus 19.6 AU
Neptune 29.2 AU
Pluto 30.5 AU

do the math.

Since the speed of light is unattainable it would take forever.
