Hi , Horse. Ok ; i will comment on some things, but try to understand that this can become complicated, and i will use some shortcuts and some simplified examples to explain in common language some of this topics, i think its better to do some things step by step. But do keep in mind that the given examples are stripped to the essential.
C is a constant, it is the speed of light in a vacuum,,; the max speed of light in a vacuum, the max speed of light in a vacuum was a postulate coming from Einstein, "postulate" , unproven and unprovable at that moment. It is proven later on, by various experiments, and proved to be correct. It is about 300.000.km/second, bit lesser, 299........etc. The most capital error in understanding this , is this , there are some variables . 1)vacuum,....to understand that there is an absolute vacuum, as in absence of pressure, to be found in space. 2) this is a tricky one, the max speed is a variable because it hides the lower speeds, by stepping over them, or the possibility of them. ...Try this one, lower speeds are allowed , possible , and not in conflict with the theory of relativity, they exist.this is long known in science, mostly it is stepped over in wikipages and other populair science-related internetcontent. Light slows down in water, air, fog,plastic, lenses, optics, etc.....this is called the brakingindex.however it regains its speed after passing the medium immediatly (Heisenberg). but it goes further. Today already it is proven that it is possible to slowdown light much further down the scale, it can be slowwed down to a halt , this is already proven, light can be halted for a split second.it can be stored and re-used. proven that all possible speeds are allowed. This is not in conflict with the postulate, nor with general, or special relativity, nor is it in conflict with the constant, that states "The max speed of light in a vacuum= 299.792.458 km/sec", this is the only thing the postulate says. So the postulate remains valid until today. it does not exclude the other speeds. I think i can find some material back on the internet about slowing down and trapping light into a halt. So remind me on this. Now , vacuum, as in absence of pressure, does it exist ,? in space , in labs? well , yes and no, there is always some contamination some molecule's or some particle's capable of distorting the experiments a little bit , but this is neglectible for common use. Note this , the max speed of light in vacuum, is equal in all directions,and independant of the observer or observed.,this mystery is unsolved .but this is unimportant for us .also note (probably important for Horse) that it is wavelenght independant , the speed counts for all wavelenghts.(diff"erent in music eh?) ...soundwaves move only in matter or air because they are pressurewaves, negative or positive-pulsing sound -backpulsing sound-echoe.neat aint it? now for gravity. The mechanism of gravity remains unsolved until today.it is unknown how it works. Most of science like's to think that is is provoked by mass. This is the path of generel relativity. this is to complicated for the forum, and it serves no purpose, general relativity can only study the EFFECTS of gravity, same goes for all other theory's.not one of them has the concluding evidence on the mechanism of gravity. Therefore all what one is able to find on the matter, on internet or science is only about the EFFECTS of gravity, the representation,,,,,,,,,,, the conceptualisation, etc, the mechanism remains unsolved. The effect , the properties, the possibilities, the value's, can we use and predict them, ..yes, they describe the effects of the properties, the value's etc....so they are to be used.they cannot be denied.So do understand that i will be talking about only the effect further on. Gravity is everywhere around us and different on all locations. How? well, mass is involved , so it depends on the observers weight-distance to the earthcore( max mass) and distance to the earthrotationsaxle.spacetime is involved because gravity , like light , is bendible, compressible, etc...(all proven). Some minor players are involved , like lake's different mass than soil,mountains, sea, etc, The location. The local location, the direct vicinity of the gravity field around a human observer, gravity is different in your backyard if you compare it to your livingroom, (masses), gravity is different in an airoplane then on the ground, different distance to earthcore-airoplane-than airoplane -observer on the ground. gravity, time is different in a satellite than it is on the ground, space/timedilatation,(relativity of speeds, bending of time). So to show an example , mostly in a sattellite in a geo-stationair position time goes about 4 full minute's slower than it goes on earth they have to correct this every day for all sattelite's depending on the orbits/speeds, different bending. In general, for us , normal people, it is normal to maintain the position that gravity on earth behaves like a freatic surface if you want me to explain this , i will, but i have to translate some things than first, for an easily understanding however,try this gravity is standing on heaps unther the earth., and interacts with us accordingly, but i will explain if you like it to be. the universe is for tomorrow, my time is ending for today, maybe i find a window in the evening.dunno. people are not aware of it , but in regard of the uncertainty-principle, this is far more easy to be made understandable then most people think, it is not difficult at all, if explained in the correct way.maybe i will do this later on, i think most people her have a distorted image of it, same goes for the copenhagen interpretation of the principle, there are misconceptions with big implication. okay, i will fill in some fields later on, ask if not clear.
