Entropy in the Universe
A common criticism of the eternal universe is that such a universe will suffer heat death trough entropy. All useful energy will at some point be spent, leaving the universe with
Energy on Mercury
Mercury makes its rounds around the Sun a little faster than Newton predicted. This anomaly has been known since Newton's time. But it wasn't before Einstein came along with his curved space-time that conventional science settled the matter for themselves…
Energy Puzzles
Every time we move things from one place to another, we do work by changing the energy of whatever we're pushing around. When we speed things up, we add energy to them. When we slow things down, we subtract energy…
Mass-Energy Equivalence
The equation E = mc², made famous by Einstein, equates energy to mass. It tells us that an increase in energy equates to an increase in inertia. It also tells us that this happens at the speed of light, in…
Light, Gravity and Energy
Gravity is known to affect the energy of photons. But it isn't immediately clear how this happens. Especially if we don't have a clear idea of what energy is. Let us therefore start with some basics regarding the nature of…
Force, Inertia and Energy
Newton introduced several concepts into physics in order to label the various parts of his equations. He did so without giving any specifics as to their fundamental nature. Labels such as force, inertia and energy were all defined in terms…
Sunspot Cycles
Ever since Galileo’s time, we have monitored the Sun closely. One thing that has been carefully registered is the number of sunspots visible at any given time.
What has been noted is
5.9 Year Cycles – The Gravity Puzzle
Conventional physics has gravity as a constant force that depends on mass alone.
There is a constant G associated with the equation expressing the relationship
Ignored Facts in Science
Contrary to popular belief, modern science is full of contradictions and unsolved puzzles, and it does not take more than mild curiosity to uncover these problems.
Understanding the Rainbow
The rainbow is fairly easy to understand in terms of particles. Many people have explained this phenomenon excellently before me, so I’m not going to
