What if I could help you?
Hello Humans,
I have been visiting your planet for a bit and wanted to give a parting gift before I leave. I enjoy reading your comments about what you call gravity. Some of you have very interesting ideas. I might get lectured by my elders for sharing this but get a sense of entertainment stimulating your minds.
I will not go into the math, I leave that up to you to figure out and this keyboard lacks a lot of the characters needed to offer a translation. Not to mention and quite frankly, the math is boring and something we learn in what would be roughly equal to your first grade. But I will give you a hint to help solve this puzzle. It really is not too complicated. You have already come so far in such a short period of time.
You already know a photon is an easy way to observe the speed of causality. There is more than one way as you know, such as gravitational waves, but light is usually the first one observed in a species.
You know a photon has no mass and travels at the cosmic speed limit. It also has no concept of time due to its maximum speed. A photon travels instantly from its own perspective.
Now think of the opposite of a photon. What could it be? Your ideas of what a graviton could be are the closest comparison. There is an extremely small particle your species has yet to discover. It is pure mass and has zero speed relative to everything else moving in the universe. It is the baseline reference point of zero motion in our reality and it is everywhere. It is...the "ether."
You have not seen this particle yet because it does not move. You constantly pass through it like a bird travels through air. These pure mass particles are even smaller than a photon. They also have similar properties of what you call black holes making them very hard for your stone tools to detect. And of course they perceive time in the opposite way a photon would. This gravitons do not experience time instantly like a photon, but experience time as it were an eternity. Their pure mass and lack of motion make time meaningless to them.
Funny enough, a few of your great minds were already on the right track. The "ether" your Einstein and Tesla spoke of were indeed this soup of motionless pure mass objects. They were on the right track, but you humans have since dismissed the ether idea because you have yet to detect it. We find this to be very funny about your species. Well there you have it and hopefully this gets some of you thinking. If I ever come back to visit, I am curious to see if anything came of this.
Anyways, I am going back to watching your shows. Your programming really is fascinating and quite popular in the galaxy. We actually use our repeater technology to broadcast your programming on subspace forms of communication so our friends in neighboring galaxies can enjoy your cave paintings as well.
Your visiting friend,
Fred.
