View Full Version : Cosmologists' greatest blunder?

2003-Sep-20, 12:40 AM
Perhaps one day most cosmologists will say that their greatest blunder was believing that the processes involving gravitation relate only to attraction which leads to the conclusion that the universe will eventually collapse if its mass density exceeds a certain amount. However, if one examines what is happening in the universe, especially in view of recent findings, one might be wise to consider other possibilities.

One such possibility is the premise that the more massive that the universe is, the more swiftly it will expand. The universal gravitational constant, G, has the value of 6.67E-11 cubic meters per kilogram per second per second. As applied to the universe as a whole, that constant might mean that 6.67E-11 cubic meters of space is added to the universe per second per second for each kilogram of matter in the universe.

Assuming that the foregoing premise is correct would mean that the mass of the universe is increasing if its rate of increase in volume is increasing. If the mass of the universe is indeed increasing, that increasing mass might originate in accordance with E=mc^2 from electromagnetic radiation that is being redshifted to lower energy levels. Understanding how that can happen might be gained through knowing the nature of one or more forms of nonbaryonic matter. Possibly it is a repository of the lost energy of redshifted radiation.

Most of the above ideas have been covered by me in previous postings.

To my understanding, red shifted radiation doesn't lose energy. If an object is moving away from us and the light it emits is red shifted, the successive wave crests just take longer and longer to reach us, hence the energy is received more gradually. At any one instant we receive less energy than we did in the previous instant, merely because there is more energy in transit, as our distance from the object is increasing.
