The only thing that can change how much the same mass weighs is being somewhere with a different amount of gravity.

Having a kilo of ice and a kilo of water just mean that you have the same amount of actual stuff (mass) in both. Density needs to also be taken into account when figuring weight. If you have a kilo of something packed into a small space, it will likely weigh less than a kilo of something spread out over a large space. So ice can weigh more than water, even if they are essentially the same substance, because the ice is tightly packed, while the water will be spread out. That's how you can have enough water packed into the relatively small space of the polar ice caps to raise the sea level enough to swallow even rather large islands whole.Drexer said:And somehow a kilo of ice weighs more than a kilo of water?

You're forgetting that Maya itself was a Mayan plot. As well as Crystal Pepsi. And New Coke.Le Tueur said:I heard that a Mayan was on the grassy knoll too. Oh and the Titanic? Mayan submarine.Metal Brother said:9/11 was a Mayan plot too.drummond13 said:Um, warned by who? The Mayans? Because they predicted absolutely nothing about the end of the world in 2012. Lord I'm tired of hearing about this crap. It's almost as bad as the 9/11 conspiracy nuts.Metal Brother said:2012 is right around the corner. You can't say you weren't warned.
Oh wait - do I need to use explicit sarcasm tags here, or are the implicit ones enough?
Both very good points. Gee, they both sound familiar somehow...Maze1125 said:The only thing that can change how much the same mass weighs is being somewhere with a different amount of gravity.

A kilogram of water will weigh a different amount on Mars than it will on Earth. But if both are on Earth, then a kilogram of water will weigh exactly the same as a kilogram of ice.
Also, ice is less dense than water, not the other way around. That's why ice floats in drinks, and icebergs float at sea.
Im sorry but Im reading what sounds a lot like FF7 when the world tried to purge itself with the life source stuffSoushi said:Yes.... one secJEBWrench said:Your movie will require some pseudoscience about the axial shift that occurred being the cause of the earthquakes.Soushi said:That;s what i figure. It just seems like they have been happening a lot and doing a lot more damamge than usual.
I mean, we aren't talking end of the world here, unless of course it creates a bunch of super volcanoes that create a cloud of dust that blankets that sky and chokes us out for thousands of years... but that may just be a hilarious senario that i will now turn in to the next disaster movie. Excuse me *grabs camera and runs out the door as fast as he can*
Coming this July
The clouds.... are upon us
The Age of man... has ended
The time of the deep dark... has just begun
The most thrilling disaster movie this year..
Can you survive...
ASH!!!! rated R (for graphic scenes of natural disaster and nudity, lots and lots of nudity)
Coming this August (due to certain script changes)
We thought the Earth was stable, that we were safe... we were wrong. Whot happens to a planet, when its most important governing force... suddenly.... shifts.
The clouds.... are upon us
The Age of man... has ended
The time of the deep dark... has just begun... will humanity.... ever see the light?

Ah, but that was actually an Inca conspiracy, created to give the illusion that John Wilkes Booth was a villain! He was a Mayan superhero, who invented the Mayan calandar using his advanced time-travel techniques. He was trying to warn Abe Lincoln with chronobullets. Unfortunately, rather than aiding the future, because of Lincoln's atomic barrier hat, the chronobullets killed him.Le Tueur said:Wait a minute!JEBWrench said:You're forgetting that Maya itself was a Mayan plot.

If you hold up a dollar bill up to the sun you can clearly make out evidence that John Wilkes Booth was in fact, a Mayan assassin.
Does this mean that Final Fantasy 7 was also a Mayan creation?ffxfriek said:Im sorry but Im reading what sounds a lot like FF7 when the world tried to purge itself with the life source stuff
but that sounds like an awesome movie. i anxiously await august
Awww, man. I thought God was punishing us for having too many different options of hat.gellert1984 said:Its Gods punishment for the peoples of Earth not being more excepting of LGBT/coloured folk.
What? Bible belters spout this crap.
I told you to not go see 2012. Honestly earth volcanic and seismic activity varies a lot. there have been many periods with many deadly earthquakes. Dont think anhything indicates a major event.Soushi said:There have been a lot of really nasty earthquakes recently. Is this kind of siesmic activity normal, is it just hitting populated area's more than usual? Or is there something else going on here, a planetary shift of some kind.
Does anyone have any idea?
Is anybody else worried?
BTW: My heart goes out to all those affected and hurt.
Clearly, not many of you were physics majors (like me). We actually had problems sets involving scenarios like these. What happens is that when the plates release their energy from hitting each other, it creates waves. The waves are the cause of the earthquakes. Since waves travel through a medium, they don't end after the earthquake, but continue to travel through the earth. They can show up on other parts of the earth as earthquakes, though generally smaller in magnitude (this is the cause of aftershocks as well). They could also trigger seismic activity that is building up elsewhere. So this guy is close in his theory.Phenom828 said:I think that because the quake in Haiti was so huge, there are movements along the cracks in the "continental plates". If one starts moving, it pushes on another one so it starts moving... It's basically a chainreaction to what happened in Haiti.
(is what I think)
They probably did as well as why duke nukem forever was cancelled the mayans never finished the game when they disappeared and game makers were trying to keep and finish the game epic but couldnt and quit trying.JEBWrench said:Does this mean that Final Fantasy 7 was also a Mayan creation?ffxfriek said:Im sorry but Im reading what sounds a lot like FF7 when the world tried to purge itself with the life source stuff

If you weigh the same mass of substance, they weigh the same. It doesn't take density into consideration.toriver said:A kilo of ice most certainly can weigh more than a kilo of water.
