What is dark energy

Open in App
Solution

Dark energy is the name given to the unknown cause of the observed large scale accelerated expansion of our universe. Scientists do not yet know for sure what dark energy is. However, the equations and principles of physics along with some deductive reasoning can give us clues as to what it must be. Dark energy clearly has the effects of negative gravitational acceleration. So a reasonable assumption is that dark energy is negative gravitational acceleration. The known laws of physics predict that negative gravitational acceleration would result from, and only from, negative relativistic mass. So a reasonable assumption is that dark energy has negative relativistic mass. Einstein's special relativity predicts that negative relativistic mass would be compelled to travel at greater than the speed of light in a vacuum, c. It is not impossible for negative relativistic mass to travel at greater than c; it is only impossible for negative relativistic mass to travel at less than c. Now, what could travel at greater than c? Neutrinos are the only particles that have been clocked to travel at greater than c. Further, neutrinos never stand still (rest). According to the principle of relativity, if neutrinos traveled at less than c, there must be a reference frame, traveling at less than c, in which they stand still (rest). Since this never happens, neutrinos must travel at greater than c. You cannot hold then in your hand or contain them in a bottle like positive matter. Neutrinos are known to be invisible, like dark energy. This is probably related to their traveling at greater than c, the speed of light. Because they are invisible and rarely interact with positive mass, it is virtually impossible to detect how many there might be. Their energy could comprise a major portion of the energy of our universe, just like dark energy. So dark energy could be, quite simply, neutrinos.

We can precisely account for the dark energy negative gravitational acceleration of these neutrinos. The subtracted cosmological constant, in Einstein's general relativity field equations, must be replaced by the negative energy-momentum tensor of these neutrinos. Please note the profound quantum mechanical implications of this new tensor being perfectly symmetric to the positive energy-momentum tensor in Einstein's general relativity theory.

Happy you asked this kind of doubts ..
you will make us proud !!
hope this helps
Regards !!
