Any idea why mass slows time down?
More mass more time dialation
More mass more time dialation
fishin_kitten said:I get all that, gravity exists because things get sucked in by the gradient of time slowing down
I do not need to see a chart to know that this is scientifically inaccurate.fishin_kitten said:I get all that, gravity exists because things get sucked in by the gradient of time slowing down (I can show a chart of this if u want)
To be more accurate, energy (of which mass is a type), momentum, and stress curves space-time. There really is no "why" here within GR apart from possibly referring to the action and the derivation of the Einstein Field Equations from there.fishin_kitten said:I'm more asking why mass curves space-time.
Again, this is not how things work.fishin_kitten said:It's like Somthing slows the passage of communication more intrinsically than say glass or water.
No, they do not.fishin_kitten said:1 Planck length per Planck time is typical, but it's as if Pt and Pl change in the presence of mass/energy
I think you're aiming at an analogy that some people use (the waterfall, or river, model, I think it's called). It's not generally applicable. The actual mathematics are more easily described as curved spacetime. That's what gravity is; that's all it is. Objects tend to move towards large masses because spacetime is curved and their inertial motion (their "natural" motion), which would be a straight line in flat spacetime, is curved towards the mass.fishin_kitten said:I get all that, gravity exists because things get sucked in by the gradient of time slowing down
That's a fair question, but you may not be satisfied by the answer: "Because that's the way the universe we live in works." Empirical science is about discovering the laws that govern the behavior of our universe, and using that understanding. It's not so good at telling us why the laws are what they are and not something else.fishin_kitten said:I'm more asking why mass curves space-time.

Mass dilation is the increase in an object's mass as it approaches the speed of light. This occurs because the object's kinetic energy increases, which in turn increases its mass according to Einstein's theory of relativity.
Time dilation is the slowing down of time for an object that is moving at high speeds. This is caused by the object's velocity affecting the rate at which time passes for it, according to Einstein's theory of relativity.
The effects of mass dilation on an object include an increase in its mass, a decrease in its length, and a slowing down of time for the object. These effects become more significant as the object approaches the speed of light.
Time dilation affects an observer by making it seem like time is passing slower for objects that are moving at high speeds. This can lead to discrepancies in the time observed by different observers, known as the twin paradox.
While the effects of mass and time dilation are present in everyday objects, they are not noticeable at low speeds. These effects only become significant at speeds close to the speed of light, which is not achievable in everyday situations.
