Let us consider the Large Hadron Collider, the largest, most complex and expensive scientific instrument ever constructed on this earth. It is drilled through rock 330 feet beneath the surface in Switzerland.
A doughnut-shaped tube, it is 16.8 miles in circumference, 150 feet in diameter. It contains enough cables and wires to stretch from Earth to the sun 12 times, with enough left over for 150 trips to the moon. It incorporates a system of 9,593 magnets weighing almost 15.5 million tons, and the entire instrument, which can produce a temperature colder than outer space, weighs over 22 million tons, more than the weight of aircraft carrier USS Ronald Reagan.
Its construction — not the cost of operation since its inception — cost $4.7 billion.
This is less than President Trump is asking taxpayers for in order to build his wall along the southern border.
