Conceptually hard to grasp... are there any theories out there that view time, like a particle, as having a rest mass, and possibly spin and charge?
ryan albery said:But empty space has properties like Eo, G and c, all of which require time, so how can time not be an actual thing too?
c (the velocity of light) is not a property of space. It is a property of spacetime. Does it answer your question?ryan albery said:But empty space has properties like Eo, G and c, all of which require time, so how can time not be an actual thing too?
So HERE you seem to agree with me that the answer to the OP's question is no.Crazymechanic said:well yes to phinds time is not a physical thing
No argument there, but what does that have to do with the question that was asked? Are you somehow arguing that the answer to the original question is yes?... the very next moment they would be at a different place so something has and changes each moment and by that we say time has run.
ryan albery said:My apologies, a better question would have been: Are there any theories that view the universe (and possibly beyond) as existing in a field of quantum black holes, with such 'particles' having the properties of spacetime?
phinds said:No, time is not a material thing and has none of those quantities.

The idea is similar to LQG in that spacetime in quantized, but different in that spacetime itself has a rest mass.
The question was spurred by my thinking that if time does have the properties of a particle, then there must be some steady state thing going on in empty space (or nearly so, considering dark energy). I don't have the skills to set up the field equations in general relativity, but setting the gravitational potential energy (with a gradient) for a 'spacetime particle' to be equal to the energy that particle gets from the Hawking radiation of the field, I get a mass and separation distance that's very close to what you get when you set the Schwarzschild radius to be equal to the Compton wavelength. This also allows me to calculate a bulk modulus for free space, along with a density, which gives a wave propagation speed that's very close to c.

Emilyjoint said:I have seen a video at school called 'it is about time' where ideas about what time is are considered. A great analogy is movie film where it would be easy to convince yourself that time was continuous but we all know the film is a series of spearate photographs.
I think there is a modern version of this relating to time itself and the 'particle' or instants of time are known as Chronons.

Emilyjoint said:If you don't mind me pointing it out...the first post asked about theories of quantised time.
I think chronons are part of that theory. Are you aware of this?
Fieldwaveflow said:Space-time is proven. You can compare the results of light coming out of a prism to that of light coming out of a double slit experiment with-edge-sensor-recorders-on. Prism light is slowed and creates a rainbow wave visual. "recorder on" sends energy from the slit to the recorder and causes the light to behave as a particle.
Fieldwaveflow said:Right. While the detectors at the slit are hooked up to recorder (that are on) then some energy is removed from the slit. According to e=mc^2 with less energy in an area there is less mass in that area. Apparently,with less mass in a region light passing through that region is altered so that it behaves as something with mass.
Anyone have a link to a single slit with recorders on?
Drakkith said:Black holes of such a size would instantly evaporate anyways.
The concept of time particles is based on the idea that time is made up of indivisible units, similar to particles in physics. This theory suggests that time is not continuous, but rather composed of tiny, discrete units that make up the flow of time.
Time particles differ from other theories of time in that they view time as a quantized entity rather than a continuous flow. This is similar to how matter is composed of tiny particles, but instead of physical matter, time is made up of these tiny time particles.
Currently, there is no direct evidence for the existence of time particles. However, some theories in quantum physics, such as loop quantum gravity, suggest that time may be quantized at a very small scale. Additionally, some experiments have shown discrepancies in the flow of time at the smallest scales, which could potentially support the idea of time particles.
If time particles exist, it could have significant implications for our understanding of time and the universe. It could potentially help explain the concept of time dilation, where time moves differently in different reference frames. It could also have implications for theories of the origin and fate of the universe.
As with any scientific theory, there are criticisms and limitations to the concept of time particles. Some argue that it is a purely theoretical concept with no empirical evidence, while others suggest that it is incompatible with certain theories of physics. Additionally, the idea of time particles raises philosophical questions about the nature of time and its relationship with space and matter.
