Dark Energy is said to be present in order to drive the observed acceleration of the expansion of the universe and Dark Matter is hypothesised to be present to drive observed gravitational effects.
Would a large mass of dark matter distributed around the outer parts of the universe have the...
If dark matter is real matter out there in space, it must be absorbing photons from adjacent stars and other bodies. Also, by definition, it is not emitting any radiation, so it must be inexorably heating up. Is this sustainable, or will it cause some sort of explosion or start the body on an...
In the two slit experiment when which path information is present there is no wave interference pattern such as would be seen with both slits being used. When a single slit is used there is a visible diffraction pattern. Is such a pattern seen when a detector forces a one slit path in the two...
If a flash of light is emitted spherically and this is measured in terms of its duration by two distant observers with one twice as far away from the source as the other, and the source and observers are all at rest with respect to each other, will the flash appear to have the same duration for...
I recently studied the data which claims to be evidence of the need for an infinite amount of energy to accelerate a body to the speed of light. This consisted of accelerating particles at different energy levels and then graphing the resultant speeds attained by the accelerated particles. The...
I have two questions concerning what happens when light interference occurs.
In destructive interference of coherent light beams, how is energy conserved, both when interference occurs in air and in a vacuum.
When non coherent light beams intersect is space there is no interference...
