I agree with the Czech scientist philosopher Mach, if it is not pragmatically experienced by some human sensation in the stream of sensations, then it is abstract hypothesis. I can experience mass, energy, inertia, momentum, force, acceleration, and yes gravity, electromagnetism, photons, atomic and sub atomic phenomenon in the chemical and physics laboratory and with the help of technical apparatus.. The Astronomy and space science that NASA has let us see is believable. I look at the cosmos and I just see what is there, all the rest is abstract hypothesis and an abundance of fanciful theories (all making `good sense' to somebody). Mathematics when it goes beyond counting and simple operations is just scratches on a piece of paper that mean nothing until it can be measured and the results seen. Call it skepticism or pragmatism or what ever you like. I've yet to see any `aging' or lack of it in space travel. |
