Does Dark energy violate the conservations laws?

Dark Energy is a repulsive force that is the dominant component (69.4 percent) of the universe. The remaining portion consists of ordinary matter and dark matter. Dark Energy, in contrast to both forms of matter, is relatively uniform in time and space and is gravitationally repulsive, not attractive, within the volume it occupies. The nature … Read more

Einstein in four *spatial* dimension

Why many physicists chose to define the universe in terms of the physical properties of a time or space-time dimension instead of four *spatial* dimensions is puzzling because, as was shown in the earlier article “Defining time” Sept 20, 2007 there is no observational evidence supporting it having physical properties.  But even more damaging is … Read more

Time travel: is it possible?

Is time travel possible? The laws of physics in the microscopic world suggest that it is because the physical processes they define at the subatomic level appear to be either entirely or mostly time symmetric.  In other words the theoretical statements that describe them remain true if the direction of time is reversed.  However, the … Read more
