If I mislead you I apologize. I'm implying that energy is driving the expansion and has been for ? billions of years. One must consider that tremendous acceleration began just after the time of the "big bang" and continued henceforth. Even small increments over the life of the universe will...
Magnetism has a directional orientation. The field will be generated strongest parallel to the orientation of the NS poles.
You might want to try this. Take a flat magnet and cut out a circular section. Drill a hole in the circular section. Cut another piece in the magnet to fit the hole...
See if this makes it simple.
Quantum mechanics is a probabilistic procedure. It is deterministic since you can predict an outcome. Once a starting point is known it has a random nature. For example of the coin toss: If we want the result of 1000 tosses starting with no previous tosses, then the...
Space itself doesn't exist. Space is a measurement the same as time. Space doesn't mean void. The ancients didn't understand air was composed of atoms and molecules because they couldn't see them - only felt the effect of air moving and saw the results. We don't see space but can see the...
Consider that space isn't expanding but is being created. If one takes two hydrogen atoms and combines them we get a single helium atom. With fusion reactions we reduce the amount of space taken up by two atoms and place the matter in the space of 1 atom thereby creating (freeing) space. Thus...
