Do you think that the earth has a weight limit?

Yeah, if you think about it, there is really no way to "add" weight to the earth unless it comes from another planet or moon.  Everything on earth at some point was derived from existing matter.  This is a rule of nature.  Matter cannot be created nor destroyed!

Assuming the population of the earth is 6 billion, and the average person weighs 70kg, that equates to 420 million tonnes (if I've done my maths correctly). If everyone stood on one side and jumped simultaneously, then nothing will happen as no weight would be lost from the earth.\n\nIf everyone had such springy powerful feet that they were able to jump to escape velocity (25000 mph) which means they won't come back down again, then that would cause a displacement in weight which would affect the earth.

earth is weightless in space. \n but your concept is interesting as applied to mass. gas also has mass so I do not think anything ever disappears. it just changes form. the gravity of the earth is what causes "weight" so the gravity of earth hangs onto the gases that develop and we all may strangle in them, but the earth and its atmosphere inclusive do not lose mass overall. saturn is a planet whos major mass is gases with a tiny ball inside of solid rock, about the size of earth. maybe we will gradually warm to a  huge gasball with a tiny rock in the middle with one person left on it smoking a cigarette and sitting in his motorhome with the motor running.

not likely- no matter how many humans populate the planet, we make up  a very small fraction of the total mass of the earth,which is the same as it always was, since very little material has been removed from the earth since it was formed. The tsunami didn't affect the earth's orbit, it affected the rotation of the earth around its axis(sped it up by about one-billionth of a mile per hour) but didn't change the speed at which we travel around the sun(orbit) at all.no matter how we redistribute material around the planet we only change the weight distribution of the planet by a very,very small fraction so the effect will be unnoticable. the effect on this planet from human activity of any kind is much smaller than we think- greenhouse gas levels were far higher during the age of the dinosaurs than they are now (and humans didn't exist then). the amount of iron and other minerals we have taken out of the ground accounts for about onemillionth of a percent of the total amount still there. from out in space, you can't look at the earth and see anything that would suggest we live here, except the Great Wall of China and the light from our cities at night, so how great of an impact do we really have?

What do you weigh at the center of the earth? Zero, because the mass of the earth is pulling you equally in every direction.\n\nYour weight is greatest at sea level. Of course your weight decreases as you go to Mt. Everest, because you are now at a greater distance from the center. \n\nBut as you go down, your weight decreases for a different reason. Now there is mass of the earth above you pulling on you in an upward direction. That is why you weigh zero by the time you get to the center. \n\nIf you are on the surface of the earth or above, the earth's gravity acts as though it is concentrated at a point at the center of the earth. When you are INSIDE the earth, as in Death Valley, earth's gravity no longer acts that way.

Earth isn't in a strong enough gravitational pull of another planet. There is no "up" or "down" in space. Earth is constantly moving, the solar system moves, the galaxy moves. \n\nI have a question for you...\nHow would you define which direction we would fall in space? Gravity is the reason we fall on Earth.

No, because conservation of momentum means the earth is a closed system. Plus, the earth weighs 5.972 sextillion metric tons (5,972 followed by 18 zeros)\n\nThe total earth population is currently 6,522,008,632. So assuming the whole world's population stood on one side ot the world and they were all typical Americans and weighed an averaged140kg each, the total human weight would come to 913081208480kg or approx 913,081,208 metric tons or roughly a giga ton (I forgot to include some of the larger than average Americans in my averages anyway) so the earth weighs approximately 5.972*10^9 times as much. Basically, you got more chance of propelling yourself to Mars by squeezing a zit on your face (even if your a really spotty teenager) than us all jumping and knocking the earth off orbit. \n\nHowever, if you got all those yanks to throw down a days worth of Big Macs at once, you might actually do it.\n\nDoesn't this make you feel really puny and immaterial to the world? Just be grateful you don't live on a gas giant.

Can the Earth sustain itself?\nOr us?\nThe earth will be around longer than we will.

No. Gravity has to do with the mass of objects--you have some too.

If the Earth's radius were bigger, and the mass of it stayed the same, then you would weigh lighter.  That's because with a bigger radius, you're farther away from the centre of gravity, therefore less pull.  If the mass change, then the situation would be different.

There is a classic experiment in Physics where you suspend a ball on a spring balance and immerse it in a beaker of water sitting an a scale. As the ball enters the water the spring balance reading reduces and the scale reading goes up correspondingly. \nThe water is like the atmosphere. After the ball is immersed the scale does not change in value even if you let the ball go to the bottom of the beaker. The ball is like the plane and the bottom of the beaker like the earth.\nThe only way to change the weight of the earth (the beaker of water) is to bring something in from outer space (the ball) but if that thing already exists on earth it is already included in the weight of the earth.\nSimilarly if you could get all your planes far enough into outer space you could conceiveably lighten the earth.

In earth's atmosphere there is gravity that comes from the core of the earth. In Space, there is no gravity or "Zero Gravity", which means space is does not move except for the obitization of the planets around the sun. But, space is endless, so, we could be falling but never hit because of infinate space. but i do not think we fall.

Humanly impossible and goes against gravity, the rotation of the earth, the moon, the sun. Joke question right?

I dont think that there is a limit.

The weight could alter, but not enough to make a difference, and not from a volcano. But if you think about it, if a 10,000 ton meteor strikes the earth, it would be 10,000 tons heavier, would it not? \n\nAnd the affects of gravity actually changes the weight of an object. If you stand on a scale just normal, and weigh 160 lbs, then thats that. If you hold a 10 lb weight, and stand on the same scale, you will weigh 170 lbs.

All the mass on the earth is being pulled in by gravity, you and me included. the more mass you have the more an object pulls towards itself and others (basically heavy things have a sort of pull, so when you are by a huge mountain you are actually being pulled towards it) \n\nThe easiest way of all the mass to be pulled together is in a sphere, there are no corners and its cannot be compressed without other areas moving further away from the centre, so theoreticlaly the earth SHOULD be a sphere\n\nBUT it isn't; due to its rotation it is fatter than it is tall, because of mass being moved out by centrifugal force. \n\nhope this helps

ALthough the exact distance at which the Earth's atmosphere (the 'sky') loses influence is debated, the atmosphere does end, so yes there is a limit to the sky.  As for space, space is most likely finite in size, but since it is expanding at such great speed, relative to someone in a spaceship, space would appear unlimited.
