Interestingly, Einstein had no lab nor equipment; he did mostly thought experiments. Albert added to the body of knowledge about the gravitational force by primarily helping us realize that gravity is the fiber of space/time itself. Similar to the air we breathe, it’s all around us, appearing both weak and super strong, as in the case of black holes.
The curvature or warping in Einstein’s theory seems more to do with cause/effect, action/reaction, or the universe co-creating in response to its creators (e.g. creators are stars, galaxies, planets, humans, flora, fauna, etc).
Newton’s Universal Gravitation lays the foundation with mathematical/scientific language that’s duly sensible. Since gravity is a Law of Attraction, Albert’s theory meshes well with Isaac’s: Everything planets or people do affects time and space -- we gravitate or attract to us -- warping or affecting space/time in the process.
Mass is certainly a factor since celestial bodies are more massive than living beings on our planet, and its effects are more dramatized in scale. However, the essence behind Universal Gravitation is that we are the cosmos (“star stuff”), and when we talk about stars and galaxies, we must be also talking about ourselves, as in this quote:
“Everything is made of atoms. That is the key hypothesis. The most important hypothesis in all of biology, for example, is that everything that animals do, atoms do... I believe it is the atomic hypothesis that all things are made of atoms -- little particles that that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling...” -- Richard Feynman
The gravitational force may be affecting us (and our relationships) in more ways than we’ve realized, but the only way to know more about gravity is to ask “new” questions that will reveal more about the great omnipresence.
“The universe never reveals its secrets ... it only responds to inquiries.”
