Question

Observations of neutrinos from the Sun have

Select one:

A. shown that there is a problem with our theoretical models of the Sun because too few neutrinos are observed.

B. led to modifications of our understanding of particle physics.

C. proved too difficult to make because neutrinos react so weakly with ordinary matter and pass straight through the Earth.

D. helped to detect the dark matter that makes up a substantial fraction of the universe.

Answer 1

Option c is correct

Proved too difficult to make because neutrons react so weakly with ordinary matter and pass straight through the Earth.

Explanation: As neutrinos are leptons they will weakly interact via weak nuclear force. They are nearly mass less and charge less and acts for a short range. Because of this reason they can pass through massive objects without interacting with them.

If ice cube neutrino telescope is constructed then we can know better about the dark matter also. Right now it is not giving information about dark matter.
