No - cold water is less dense than warm water.

That's why ice floats.

I think it's Giganews. *Same thing here. *I posted a response shortly after

Sounds like Giganews is gigging its subscribers.

1648 today's date. There is a -0500 which would equal UTC time
difference.

That's when I sent it, but no sign of it Giga News server even now.

Thanks

I just noticed that my Easynews feed just started to post quickly - or
at least quicker than it had been posting.

I wonder if there was a system wide glitch or something? I just
googled around and there are other paid news servers that are having
similar problems - it's not just giganews or easynews.

Hmmm....

Depends on the temperature. Max density of fresh water is about 5 degrees
C. Ice floats because it causes a local aberration in gravity.

What you say??? Nope. Ice floats because it goes through a phase
change and expands when it freezes.

Liquid water density decreases as temperature goes up EXCEPT for a
very strange behaviour in that it's maximum density is at 4 degrees C
and drops from there down to 0, where it freezes. So from 4 degrees C
on up, colder water is more dense than warmer water. But the
difference in density is so slight I doubt it would make any
difference to a plane crashing on it.
