Thoughts on Space/Time and Gravity

[Manosapien]

Some of my thoughts on space theory. I see many similarities between space/time and water. Just how they both move and flow. Only one thing is faster than light and that is the expansion of space/time it self. We have discovered that space is expanding faster and faster. This is the reason why time is always moving forward since the the two are connected. Einstein stated that gravity is matters curvature of space/time. To go beyond that, I think that gravity is matters restriction of space/times movement. In normal empty space time ticks faster than here on Earth. I think matter is sort of pinching space/time, making it expand/tick a little slower. At gravities extreme a black hole, you can see this effect much clearer since they say if you park a spaceship next to a black hole its clock would almost come to a stop. So this must mean space is almost coming to a stop.

Please be aware that PF rules do not allow personal theories. We would be happy to explain current published theories such as General Relativity, but we cannot discuss you own personal one. (Which doesn't quite match up with observations and accepted theories) If you would like to learn more about it then head to the 3 subforums on Astronomy, Astrophysics, and Cosmology and read the FAQ's there or do a search for other related items. There is also the General Relativity subforum as well.

oh sorry. I saw the general relativity section but thought I could post in this section also since it was general physics. Just curious what part doesn't match up with observations?

I guess it isn't really about matching the observations, but more about the interpretations of what spacetime is and how it works. Saying it "flows" and "moves" and such doesn't really match up with what General Relativity says. It's hard to explain as I'm not an expert on GR. Spacetime experiences "curvature" as many call it, but what that's really talking about is how the geometry of it changes I believe. I'd suggest looking into the more technical aspects of GR and if you have specific questions then feel free to ask. Just try to refrain from posting your personal "interpretations" of what spacetime is doing and you should be fine.

I find the comparison between space/time and water to be an interesting analogy. However, it is important to note that while both may exhibit flow and movement, they are fundamentally different in nature. Space/time is a fundamental aspect of our universe, while water is a physical substance that can be observed and measured.

The concept of the expansion of space/time is a well-established phenomenon in cosmology. It is believed to have started with the Big Bang and has been accelerating since then. This expansion is the reason for the observed redshift of galaxies and the increasing distance between them. It is also the reason why time appears to be moving forward, as you mentioned.

Einstein's theory of general relativity provides a framework for understanding the relationship between gravity and space/time. According to this theory, gravity is not a force between objects, but rather the curvature of space/time caused by the presence of matter. Your idea of matter "pinching" space/time and slowing its expansion is an interesting concept, but it is important to note that gravity is not just a restriction on the movement of space/time, but rather a fundamental aspect of it.

The phenomenon of time dilation near massive objects, such as black holes, is well-supported by both theoretical predictions and experimental evidence. The extreme gravity of a black hole causes a significant distortion in the fabric of space/time, resulting in a slowing of time for an observer outside of the black hole. This is why time appears to almost come to a stop for an outside observer, as you mentioned.

Overall, your thoughts on space/time and gravity are intriguing and show a good understanding of these complex concepts. However, it is important to continue exploring and researching these ideas to gain a deeper understanding of the fundamental nature of our universe.
