scientists have now figured out what the speed of gravity is.
According to some recent expiriments, gravity (the energy) is emitted at the speed of light. Do NOT confuse this with how fast an object pulls you toward it with its gravitational pull. Rather, gravitational waves are expelled from an object. The waves are what travel at the speed of light.
But, we still don't know exactly what gravity is.
We know what it does, and we know all the mathematical formulae for mass and gravity, but we don't truely know what gravity is.
Now that they have discovered the speed at which gravity travels, maybe we will start to get a better understanding of what it is.
Chances are, it may not be a part of the electromagnetic field, but maybe it could still somehow be related. Just a thought:
Just as any moving electric charge has a magnetic field, so does every object with mass have gravity. If you want to get to the nitty gritty, gravity is a measure of an object's mass, so any object has gravity, including air.
But, as far as I can recall, magnets, themselves, don't have moving electrical charges. They have magnetism without. I'll have to look that up again, as I really can't remember.
But, there is nothing analagous to the magnet in the gravity situation. That is, there is nothing which doesn't have gravity, and there are no gravity fields with nothing causing them.
Gravity has similar characteristics as light (and other electromagnetic fields). They are emitted in an isotropic fassion. That is, from a center point out in a spherical manner. If you take imaginary spheres with the center as the same point as the center of gravity or the point of origin of light, you will get the same measurments of intensity at each point on that sphere. Both gravity and light also follow the inverse square law, which basically states that at double a particular distance, the intensity will be one-fourth that at the primary measured distance. To further clarify that, if the intensity of light at one mile is 40 candles, at two miles, it will only have an intensity of 10 candles. If you weigh 200 pounds at a distance of 10000 miles from the center of gravity of an object, you would weigh only 50 pounds if you moved out to 20000 miles.
So, these are some shared characteristics of gravity and the ems (electromagnetic spectrum).
We tend to measure the ems as a sine wave on an x axis of an xy grid.
I am wondering if there isn't actually a third dimension to the ems, a z axis; and instead of the ems just being a sine wave, perhaps it is instead a coil which wraps around the x axis. I don't know... maybe someone has already thought of it and proven it true or false. If so, I'm out of the loop (no pun intended).
Now, with an ems sine wave (coil?) you get an alternating positive then negative charge. The speed at which it alternates is measured in hertz (Hz). In America, we use electricity at 60Hz, which means the positive/negative alternations occur at 60 times in one second. This is what we call alternating current (AC). Direct current (DC) does not have this alternating positive/negative pulsing. It's just plain steady. You get AC from your electrical outlet, you get DC from a battery. I know of no battery that has the ability to produce AC.
Now then, does gravity behave in the same manner? We don't know. Is there some chance that there is some sort of sine or cosine wave along either the y or z axis on a 3-D graph which represents gravity? Or not even a wave, but a coil? Or, maybe it's just like DC ems and steady like the formula x=1.
Or, what if gravity is, in fact, a complete negative of the whole ems system?
Not the negative charge where y is a negative number. No, I'm talking about something similar to anti-ems. But not like matter vs. anti-matter. These two antis would have to co-exist. They couldn't cancel each other out. The closest thing I can think of is like looking at a negative for a picture. But that's still too 2 dimensional in my thinking. But I would hope you get the general idea of what I'm trying to say. So, if ems coils around the x axis one way, then maybe gravity coils around it the opposite direction. Or, as I mentioned, maybe it coils around one of the other two axes. Or, maybe neither one has the coiling effect.
Now that scientists have discovered the speed of gravity, maybe we'll begin to discover more about its properties.
Maybe then, will we actually know just what gravity really is.
