To be able to penetrate very deeply into the matter we need to generate very high energies, we need somehow very energetic particles that can test very small distances inside the matter. And for that you have to build particle accelerators. For example, a proton is a constituent of the atom, the nucleus of the hydrogen atom. These particles accelerate in an accelerator until they reach speeds very close to the speed of light and the highest energies ever before reached by a man-made instrument on earth.
Then with these high energies we test the small distances, the deepest structure of matter and what is interesting is that by producing these enormous energies in a laboratory and in a tiny microscopic region of space we are reproducing the conditions that were present in our universe primitive. Actually in fractions of seconds after the Big Bang.
Technology is enough for us today to reach 10 ^ (- 10) seconds after the Big Bang (ie 0.0000000001 seconds).
In case, the major ocean currents stops or slows down, the heat distribution on the Earth will be affected in the following ways:
There would be quite significant climatic changes.
It affects one of the major phenomena in the ocean , the thermohaline circulation of the ocean which is responsible for the supply of heat to the polar areas.
Heat distribution is affected in such a way that keeps the warm water of the equatorial region remains in the same region and can not delivered to the polar areas.
This phenomena results in more heat in the equatorial region and colder polar areas.
