The mudflows occur mostly because because of enormous amounts of rainfall, and occasionally they occur near volcanoes. The lahar represents a violent type of mudflow. It is composed of a slurry of pyroclastic material, water and rocky debris. The material flows down from a volcano, usually along a river valley. This type of mudflow is extremely dangerous, and it manages to cause a lot of damage as there's hardly anything that can stop it or resist its force.

We have direct experimental evidence (from large particle accelerators) for the physical conditions in the universe back to abou

Nady [450]

Answer:

c. 10-10 seconds

Explanation:

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).
