These rocks were 5 tons! So how could it of it been built?

Stonehenge was probably built by transferring huge slabs of stone and sculpting them by lighting them on fire, and then pouring cold water on them. Nobody really knows why. Some people claim it was built by the Druids as an altar. It also could have been an astronomy site. \nMy question is this: why build it out of extremely heavy stone when there was wood in abundance? ( Whoever built it probably transported the stone on rollers.)

please do not do this for a science project.  too common.  but if you really want to know...most ppl get a small coke bottle and mould clay around it to get the mountain shape.

How would the last Truck hold all the weight!?!?

Most rocks thought to be meteorites are not. There are what they call "meteorwrongs". I found a rock myself that's all metal and rather heavy. That's how I found this site. You could also take it to a museum. Someone there will know. Take a look at these pictures.\n.

Considering the year, they were fairly expensive to build. This website gives exact details.

It has it's flammable state...Try to imagine it as a fuel air bomb.Thn there you will get your Idea.

how about a shovel to lift the rocks

The rocks provide a stable base called a Track Ballast which the railroad ties rest on. The crushed stone is used for the drainage of water, and to create an even surface.

ok first of all just because one thing the bible says is true,that wouldnt make the entire thing true and second of all,originally the Earth was a ball of molten rock that cooled down.water didnt come around till later(im not sure how though)

Ah.. Get back with us if a few years..... lol\nThen we'll KNOW the answer.\n\nBut I would think #3.  Mount a rocket motor on it. It's got a lot of mass to get moving with the other methods not being, today, that efficient.

it seems crazy that sky scrapers can be so high and not fall down on their own.  this is because it is full of materials that have been tested before to failure.  the structural engineer knows that every beam, joist or member has a certain design load capacity.\n\nby figuring out what the design of the building is, what materials will be used and what the different loads will act on the structure, the structural engineer will be able to adequately design a system that can carry the load.\n\nfor example.  a 5 story building is to be built.  the soil needs to be tested to see if it can support the foundation.  depending on how many people will load the floors, structural beams will be designed to support such loads and more.  most structural systems have been done and tested before so there is plenty of documented evidence that a certain structural system will work.\n\nnot to mention that many structural engineers now build their work virtually.  they can apply different simulations e.g. seismic loads to see if their calculations work and see it virtually withstand the loads.\n\nhope this helps.

The first Argonauts of 1848 used quite primitive mining tools: knives, spoons, a shovel, and a pan for washing the gold. Since these miners could only dig out bigger nuggets with such primitive equipment, they had to work on rich gold deposits. In the same year, technical improvements such as the cradle, the rocker, the long tom, and river damming, basically all known since the Middle Ages, were introduced by the more experienced Mexicans. The cradle and the rocker both worked on the same principle: wooden boxes with the top and front piece missing and a sieve on the bottom side through which the dirt containing gold was washed. On the bottom horizontal wooden bars slowed the incoming water down and helped to separate dirt from gold. With a handle on the side of the box, the whole mechanism could be rocked. The rocker required 3 or 4 people to work, one to shovel the dirt into the machine, one responsible for the water supply, and a third one to move the handle. Contrary to the individual washing with the pan, this more efficient technique required miners to find partners, thus establishing small mining groups of 3 to 9 people.\n\nThe long tom functioned similarly to the rocker but increased its efficiency. It also had the shape of a trough, but it was much larger, 12 to 15 feet long and about 2 feet wide. Mainly made out of wood, it had a metal bottom with a sieve and a ripple box at its end. This machine was put up with a slight slope, thus facilitating the water flow. While one man shoveled dirt into the long tom, making sure that the water was running, another mixed water and dirt while taking out big stones that could damage the sieve. At the end of the day, the dirt was taken out of the box and washed in a pan. Six to eight men had to work a long tom to fully exploit its capacities. A few miners started to employ the long tom at the end of 1848, and by 1850 it became a common machine.

First off, much of the interior of the earth is molten after you get about 30K down, so you couldn't really drill a hole through it. But for arguments sake, let's say you built a super-strong tube out of some nano-material and inserted it through the center of the Earth from pole to pole. Now you drop your stone.\n\nThe stone would fall towards the center of gravity, the center of the Earth. It would accelerate as it fell, so it would presumably fall past the center and head towards the South Pole. As it headed towards the South Pole, the gravitation pull would slow it down. Would it manage to to escape the Earth's gravity? No.\n\nConsider that the stone being at the top of the North Pole represents "potential kinetic energy". You could have generated energy from its fall much like a dam creates energy from falling water. Instead, it fell freely towards the center of the Earth, and all its potential kinetic energy has been turned into velocity. That velocity can't be enough to go any further than it fell (that is, out of the South Pole) because where would the excess energy come from?\n\nNow when the stone is at the center of the Earth, it has no potential kinetic energy. It can't fall anywhere, because every direction is up. All of its potential kinetic energy has been turned into velocity and so it should "fall up" the distance that it fell down. When it reaches the South Pole, it will have no velocity left, but it will have the same potential kinetic energy as when it started to fall. So you might expect it to fall from pole to pole indefinitely.\n\nHowever, if the tube is full of air, we have a problem. Falling objects normally have a "terminal velocity", which is the speed at which the air resistance stops the object from accelerating further. The air pressure at the center of the Earth would be enormous (air would probably be a liquid at these pressures and temperatures), as it would be subject to the weight of the air both north and south of the hole pulled in towards the center. The increasing density of air would slow the object as it fell to where it had little momentum as it approached the center. It might overshoot somewhat, but friction would continue to slow it until it was drawn to the center of gravity.\n\nNow if the tube contained a perfect vaccuum, the object should continue to fall from pole to pole indefinitely...except there's the problem that the stone would hit the sides of the hole due to the rotation of the Earth. See Foucault's Pendulum. This would slow it down, causing it again to settle at the center of the Earth.\n\nThere you have it. No need to drill through the center of the Earth now.

Obviously something man made...There is no such real stone

I see a whole lot of people parroting what they've read and seen on TV, but here's an new and original thought for you...What if the blocks weren't pushed, pulled, levitated or moved into position at all?  What if they were "poured" into place as a sort of cement?  Think about it...They would've easily done it level by level, filling any smaller gaps with smaller blocks....\nAnyway, that's the only thing that really makes any sense to me.\nPulleys and levers, ramps..All that stuff has basically been disprove...If they were constructed in either one of those manners, then why can't we reproduce the great Pyramid using the same technology?....We should have pyramids all over the place!!!\nI like my cement theory!

Perhaps you can picture it this way.  Take your 2,000 ton ship and melt it down and use it to make a very large solid steel cube.  Mearsure the cube and obtain an equal cube of water (say frozen into ice?).  Place the two cubes on opposite ends of a giant seasaw.  The steel cube weighs more than an equal volume of water and goes down (sinks!).\n\nTake a second identical steel cube and build a typical ship.  While still in drydock, fill the inside of the ship with water up to the intended water line (based on an identical ship?).  Drain the water out and use it to make another really giant ice cube.  This ice cube will now be much larger than the cube of steel.  Now place the steel cube and the ice cube on the seasaw.  The weight of the water goes down and the steel cube goes up (floats).  The weight (volume) of the water inside the drydocked ship is equal to the weight of water displaced by the ship (shoved aside by the floating ship) and acts upwards on the bottom of the ship with the same force it had on the seasaw.  It is more than enough to make the ship float unless the ship is loaded up until water flows over the side of the ship and floods it.  Hope that helps a little.
