Physicists have been trying to describe the nature of the space between the objects they can observe in the Universe for centuries, variously described as the ether or other terms. Because we still can't accurately describe energy or quantum particles, many refer to the energy that permeates the...

Technically, yes, mass is mass. My point though was that the more mass that cumulates in space, such as planets, stars and other large objects, the denser they become at their core as the accumulated mass is compressed inward. This is the very reason stars begin fusion. At the quantum level, it...

I suspect one of the problems for many, including some academics, is the use of the term force when discussing gravity.. It is more accurate to describe gravity as an effect. Everything in the Universe is made of the same stuff, energy, but is clumped in space at different densities. The greater...

<< Mentor note -- posts broken off from an Insights comment thread >> Ok, this is where I show my ignorance, but all this is theoretical and why I get lost with these academia discussions. Time is just a mathmatical construct to measure the motion of two or more objects relative to each other...
