Gravity is constantly demonstrated for us on Earth in these everyday and quite ordinary ways. Water makes a droplet because the leftover attraction from its small molecules mildly reaches out reciprocally to join together several water molecules so that they clump together. The same sort of thing happens to cause water vapor to form clouds instead of them remaining diffused and separate in the atmosphere. Also, cooling water molecules make their electron shells contract which makes the their leftover reciprocal attraction stronger since the space between the involved nuclei, molecule to molecule, is reduced by that; even as they so often condense together on the side of a cold object and/or turn into attached frost if the temperature is cold enough.
An elastic material like a rubber band also exhibits gravity. In that case the joined molecules making the solid material are joined together too tightly to behave as a liquid; while the attraction between each of them isn't strong enough to form a rigid solid. Thus they can be pulled apart and stretched while they attempt to keep holding onto one another.
Einstein didn't really understand gravity correctly at all when he came up with his relativistic interpretations. He came up with those because of the curious orbital pattern of the closest planet to the Sun in our solar system: Mercury. Mercury's orbit has an orbit like a spirograph pattern, wherein its perihelion (its closest distance to the Sun as it orbits) is constantly changing each time it circles the Sun, which Einstein thought was caused by the relativistic type dynamics that he devised for explaining that. But the real cause of Mercury's unusual orbital pattern is Sun wobble, which Einstein and every other early physicist of his time knew nothing about--a solar feature that is now common knowledge. So once again the behavior of atoms and molecules, including celestial bodies, is distance sensitive so that while the Sun wobbles it is constantly moving from what would be that star's most central location, which constantly changes the side of the Sun that is closest to Mercury's perihelion which makes Mercury's orbital path respond accordingly.
Gravity is what causes objects to orbit sufficiently massive bodies by curving a straight or nearly straight path of an object and/or smaller celestial body, that flies by so that its velocity combines with its reciprocal attraction to that more massive body, which dynamics are then compromised together into a perpetual type orbit. If an object or celestial body come in toward a sufficiently massive body too directly the object and/or smaller body will collide with that larger body's surface and not orbit; thus it's assimilated into it. That means orbits, whether already slightly curved (due to another more distant gravitational interaction), or else virtually straight, will gradually adjust so that they typically form a relatively stable orbital path, or in certain cases more irregular yet still perpetual type orbits.
Acids and bases are essentially expressions of what causes gravity as well: i.e. leftover attraction. Acids are generally smaller molecules that surround a material so that their leftover attraction attacks it at very close range, which can be strongly disruptive if the acid is a strong one. Bases are larger molecules that can't get as close due to their size when congregated in a liquid. But their leftover attraction is generally greater than those from acids; although the extra distance mollifies their attraction strength to some extent. The reason litmus paper turns purple instead of blue or red when you mix an acid with a base is because the most attractive side of the acid molecules is turned toward the most attractive sides of the base molecules so that they essentially stop attacking whatever other material they might be in contact with. It's not because of negative and positive charge wherein the mixed acids and bases would become neutral since negative charge doesn't really exist; only uncharged photons on up in small graduated levels (a total of 20) on up to the medium and then highest levels of positively charged photons. Meanwhile this system explains how photons get charged to different levels and that they can become uncharged again via the strong gravity of the largest black holes, particularly one source collection of photons, that periodically spews (once every several billion years) photons out into space in two opposite directions, which black hole resides in the center of where galaxies are making circular paths as they travel through space to eventually return to that enormous source collection since very significant (although low level at that distance) gravity is constantly reciprocated between that central black hole and those galaxies.
To explain all of these things there is no need to resort to those highly counterintuitive relativistic explanations, such as "warped" space or a "fabric" in space playing any role at all in how and why some bodies orbit others, which is a completely bogus concept. There is no need whatsoever to envision what have been termed "gravity wells" either--another erroneous explanation that tries to legitimize the notion of "warped space." Along with that, there is definitely no real basis to support the spurious conclusion that gravity waves exist, which for one thing is founded on the false idea that light waves are massless, which they are not as these charts also correct while they lay that out in the most detailed way imaginable. Photons are not massless nor do they need to be to do what they do in the universe each day. Wherefore, the contrivance of massless waves arose as a religious (ie. spiritual) oriented presupposition.
