Try runnig ethereal.  It will show you the actual traffic and you can look at stuff by port.  There mays be clues in the content.

Quantum tunnelling ( passage of electrons/atoms through a potential energy barrier and/or other matter .... it's a probability thing ) has been suggested as a possible reason.

the one who answered first... plzzzzzzzzzz\n\nexcellent answer but.. trains moving towards each other can also be said to move in opp directions.

If its an 'ideal' problem, the rock wouldn't land anywhere.\ninstead it would execute a simple harmonic motion ( same as the behaviour of spring-block system with gravity providing the elastic part and mass of rock providing inertia)with amplitude equal to the radius of the earth.\n        but , if the air from the atmosphere were to gush into the tunnel then the rock will experience a drag and after a ong time it will come to rest at the center.\n        to be more precise, if i drop a rock from singapore to mexico (i.e. along the equatorial plane) , the rock will move to side abd hit the wall of the tunnel(because of the pseudoforce called cariolis force)during which it will lose lot of energy and come to rest quickly at the center.

The best tube is one you make your self. Take some news paper and rap it around the mentos until it seems hard enough.

Dig a tunnel from wherever you are to Germany\n\nP.S If you want serious answers to sports questions, dont put it in the science section lol:P

step one: put suction cups on the bottom of your shoes\nstep two: walk up the wall and suction your way along the ceiling upside down\nMission Impossible Style\n\nOR\n\nPut mirrors a foot or two away from the infared light to reflect it back to the sensor and walk on the other side of the mirror and wall safely \n\nOR\n\nIf the sensors are low to the ground or all in a straight line and you have access to both ends of the hallway\nplace a supportive structure at both ends and run a ladder from one end to the other and shimmy or crawl across carefully to safety...\n\nOR\n\ndig a tunnel under the building\n\nOR\n\nrun quickly as it taked like an hour for the security company to contact the client and and the alert the police and respond - movies lie- steal a car, break in , be quick about it, grab the loot, and drive away slowly, ditch the car and dont truct anybody!

Depends where you are on the planet and what you call 'warm'.\n\nThe deep diamond mines in South Africa are about 50 degrees C and a couple of km deep.  In Iceland, Siberia etc geothermal heating is powered from bores drilled about 1km deep.\n\n=================================\n\nADDED LATER:\n\nThe average subsoil temp in the UK is about 6 degrees C (subsoil being the inorganic soil that lies below the 600mm deep topsoil), if you ever go down caves in the UK you'll find they're about 6 degrees C (unless there's air blowing through them).  There isn't a great deal of difference in subsoil temps across the different parts of the UK.\n\nAssuming that at 1000 metres depth the temp is 40 degrees C and at ground level it's 6 degrees C then by interpolation you'd have to go down to about 500m to reach 23 degrees C.\n\nJust out of interest, why would you want to dig down to reach 23 degree temps?

speed?\n\nquantum tunneling happens by chance in time, so the word speed doesnt apply here.\n\nBut once it takes place, the tunneling occurs at the speed of light.

1a.  Since blasting is going to create instability in the surrounding material for a greater distance, digging will produce the more stable tunnel.  Assume you are depending upon the natural surroundings to support the shaft and not introducing artificial shoring.\n\n2a.  Technically since work is defined as the amount of force required to move a mass through a distance, both will be performing the same amount of work.  Benefit will be gained by the conveyor system which can essentially move material 100% of the time if it can be loaded continuously.  To achieved the same with cranes and trucks, there would have to be enough cranes so that a full load was constantly moving up the shaft.\n\n3.2.  Not sure what a "gigantil fisility" is let alone if one can be constructed of "concreat".  Also the debris being removed from the shaft may not be suitable component of "concreat".  Best option would be to sell it or give it away.  Probably some big holes around that could be filled in.\n\nConstructing a gigantic facility out of concrete might even be an option if you had enough Portland cement and the shaft debris was a suitable aggregate.

A whole lot of looking and often by accident! Amateur explorers often find important digs, and most building permits these days require a quick archaeological exploration before they send in the shovels to tear through - this is how many old remains have been found...just before a subway tunnel was going to go through.

You are going to need to use a proxy website.\n\nhttp://www.phpproxy.com\nhttp://www.secure-tunnel.com\n\nI'm glad that I could contribute in some small way to you ruining your education. ;-)
