About 6 light years then.Somewhere around Barnard's Star.

So quite a bit beyond Proxima Centuari!Yeah like 6 light years or so. 1e18 was inches not meters. My original estimate was only off by a factor of forty.

Ok, have a rough stab at the Maths in your head and have a guess.I remember the last time my father and I were in the hardware store. He wanted to re-paint his living room, and was checking to see how many square feet a gallon of paint would cover. Once we had the number, we both started babbling - he in "old math" and I in "new math." We came to the same answer at the same time.

It's how he taught me, it's how I do things. "Don't guess" he said, "you'll be wrong." If I'm not allowed to run the math (at least in my head) then I'm stuck at square one.

Really! So get your calculator out and convert that mass to metres.The cumulative mass of the coins will be comparable to that of Jupiter. The stacks of coins will colapse into a ball under their own gravitational pull.

3.1 light years is pretty precise, care to share how you came to that?if one coin is 3.175mm thick

so my guess is abt 3.1 light years ,

lets go see it for ourself, your car got enough fuel

i bought potato chips with the money on the 64th square.

Next conumdrum: What is the area ofWell, I know that if you fold paper over 50 times it will reach to the sun.. (Actually THAT is our closest star)... so accounting for the different thickness's and the extra 14 doublings, I would think Papabravo's estimate to be fairly close.

*that*piece of paper?!

Oh, and we've another guess at 6 light years.

Sure do, the bag has an infinite number of coins!Hey man - spare change?
