math riddle

[Brian Ellis]

IMHO nearer 150 trillion tonnes (incidentally, a tonne is metric, by definition, so doesn't need the qualifier). Reason: you have used the AVERAGE weight of ther earth as your basis, but 2/3 of the surface has a density slightly greater than one and the other 1/3 slightly greater than 2, on an average (mainly sedimentary calcareous soils). The heavy stuff is in the iron core in the middle.

I actually did this on paper...about 15.9cm. Normally I would've chosen "wow... a rope that long...." but I actually wanted to do the math this time.

Six sextillion is a ridiculous number.. can the Earth really be that massive?

[Nowhere]

Our minds aren't used to the scale of universe, KvH...

[GNEP]

How big was Ringworld meant to be again?

[UtwigMU]

I calculated also, thus haven't voted.

Yes, it actually can/is. It's pretty damn ridiculous, to be sure.

Contemplating Jupiter makes grown men weep.

And that's just in our puny little local area.
Where things aren't really very big.

Actually, I gave him that choice.
Depends on whether you see it as added to the outside or as a general scale up.
Take your pick.

Six sextillion = 6, (how many zeros?)

[Gurm]

Six sextillion = 6, (how many zeros?)

10^21

Pretty f-ing big.

[GuchiGuh]

geez....pretty damn f-ing big man!
and to think that all the mass in the universe was once compressed into the space of a pinhead....someone calculate the density of that scenario, am busy at the moment

[cjolley]

= 1 U/Ph

You just have to pick the right units.

[GuchiGuh]

An Interesting number I just got to know today!

very impressive!

I'm too lazy to check mass of the universe, but be careful not to go too far - when universe was younger than Planck time
