kai00 Posted May 12, 2021 Posted May 12, 2021 So I have been trying to make sense of what space-time is from a practical point view. I thought of sharing with you some thoughts that came to my mind. 1). The fabric of space must be made out of the smallest wave-like phenomenon. Since this is so tiny, think of it as the smallest particle. These particles (or let's call it a field), fill the entire universe. 2). When we place a heavy particle in this field, the particle would pull this field/the fabric of space (that acts as if it a spring) in every direction towards the particle and that's based on the mass of the particle that we place in this field. This pulling force that exerts on the spring, would depend on the mass of the particle. So let's say we place three protons next to each other in this field. If so, these three protons would pull the spring towards them with an equal force (since the mass of the protons is the same), therefore, protons can’t get close to each other. Similarly, two electrons would also pull the fabric of space towards them with an equal force, even electrons can’t get closer each other. 3). Now, let's say we place a proton and an electron close to each other. Since the mass of the proton is high, compares to the mass of the electron, the proton would pull the electron closer since its pulling power on the Fabric of Space is much larger (note that this pulling power depends on the mass of the particle). Since a proton pulls an electron closer, we call protons as positively charge and the electron as negatively charge (this is what we call as a charge). (Imagine, proton (the blue ball) and the electron (the small red balls) pull the Fabric of Space towards each other, but since the proton's mass is larger than the electron, its pulling power on the Fabric of Space is larger, so the proton can pull these electrons towards it. More, protons means, there's more force on the Fabric of Space, so it is subject to a larger contraction (imagine, this spring getting squeezed), compares to a contraction of a single proton. The Four Forces: The mass of the particle and/or object, would always distort the fabric of space however and how far it can affect the fabric/field would depend on the mass of the particle. For instance, since the size of the proton is small, its effect on the Fabric of Space span only a tiny distance and when it comes to quarks, it’s even smaller. Strong Force: Since the mass of the neutron is larger than the proton, the neutron pulls the Fabric of Space with a great force than a proton, therefore, it pulls the Proton towards it. Since the masses of these particles (neutrons and protons) is larger than the electrons, their pulling power is larger, so we see this as the strong force (which we see inside a nucleus). Weak Force: The quakes that make the protons and the neutrons are smaller than protons and the neutrons, and their mass is also small. This means their pulling power is also small. So, we see it as the weak force. Electromagnetic Force: Since the mass of the proton is larger than an electron, it pulls the Fabric of Space towards it with a greater force, so for instance, it pulls the electron in a hydrogen atom. We call this the electromagnetic force. In a helium atom, this force is large, since its nucleus is made up of a neutron and proton that has almost identical masses. Gravity: When we talk about Gravity, we talk about planets and other massive objects which are made up of a massive amount of atoms. Since we are referring to a planet, on this occasion atoms as a whole pull the Fabric of Space towards the planet, so the Fabric of Space or this field that consists of the smallest particle-like phenomenon contracts. Since the size of planets is massive compare to protons, neutrons, and electrons, planets can affect the Fabric of Space over larger distances. And that's because its pulling power on the Fabric of Space is so high. This pulling force on the Fabric of Space is high on the surface of the planet (Therefore, the amount of the contraction on the surface is high. On the other hand this increases the density of the smallest particle-like phenomenon), compares to the pulling force exert on the Fabric of Space at a distance from the planet (therefore, the amount of contraction gets smaller at a distant, this deceases the density of the smallest particle-like phenomenon). When this pulling force becomes weak, the gravity becomes weak (We know that this strength is inversely proportional to the square of the distance from the center of the Earth. So, the effect rapidly declines). Bending of Light around a body: Since large objects contract the Fabric of space (or this field consists of the smallest particle-like phenomenon) over larger distances, the density of the smallest particle-like phenomenon increase on the surface of the planet (the Fabric of Space contracts), and this density decreases as it moves away from the planet (the Fabric of Space contracts but much less compares to the surface). In other words, massive objects distort the Fabric of Space (Einstein called this as curvature of spacetime) or the field that consists of particle-like phenomenon. Therefore, this curvature changes the path of light. Light Energy Loss: “This is fundamentally what happens to light, as it travels through an expanding universe. The universe as a whole is expanding, meaning that the space between many galaxies is increasing. As light travels away from a galaxy, the Universe is continually expanding, meaning that the distance the light needs to travel is continually increasing as well. As space stretches out underneath a beam of light, its wavelength increases, and its energy decreases” Source: https://www.forbes.com/sites/jillianscudder/2017/04/28/astroquizzical-light-energy-loss/?sh=22cdf7815768 Alternative explanation The reason why wavelength is increasing is that the tension of the fabric of space between the particles that fabric is made up of reduces (this is because galaxies/planets are not affecting the fabric of space to contract that much when we go towards the edge of the space). Therefore, the distance between these particles increases (the particle-like phenomenon that the fabric of space is made up of), this increases the wavelength of a photon. When wavelength increases, its frequency decreases, therefore, photons' perceived color would change. This can be identified as the reason behind redshift. (There’s no such a thing called space-time. It’s a mistake). However, the fabric of space does experience a contraction or expansion depends on the particles/objects in a given location in space. The more the mass, the planet/object or a particle has, the pulling power increases, this is what causes the fabric to contract (or the particle-like phenomenon that the fabric of space is made up of).

There is no fabric of space, you seem to be confusing an analogy with the real thing. Space is a volume so saying it is made of particles makes no sense. Since your idea is based on this idea of a nonexistent fabric the rest does not make sense either. 1

Same mass relationship, but a repulsive force. Quote Similarly, two electrons would also pull the fabric of space towards them with an equal force, even electrons can’t get closer each other. But electrons do more than "not get close to each other" - they actively repel, with the same force as exists between two protons.

We call this the electromagnetic force. In a helium atom, this force is large, since its nucleus is made up of a neutron and proton that has almost identical masses. The electrons are pulled with the electrostatic force. Deuterium doesn't have twice the attractive force on an electron owing to the extra neutron. The effect is small, owing the different reduced mass of the system, which shifts the energies a small fraction of a percent - not anywhere close to a factor of 2. 1

Quote Before repel two electrons must come closer. So I think it could be that the electrons end up increasing the tension of the Fabric of space ( The field that consists of the smallest particle-like phenomenon) while trying to come closer. Here at some point the electrons will not be able to push any further, so it will start releasing this tension (imagine a scenario where a mass ends up squeezing a spring). Perhaps, this could attribute to the repelling behavior. Good questions, I don't have answers to all the questions you raised. But one thing to note is that the radius of the Deuterium nucleus is smaller than expected. https://physicsworld.com/a/proton-radius-mystery-deepens-as-deuterium-measurement-comes-up-short/ 3 hours ago, Bufofrog said: There is no fabric of space, you seem to be confusing an analogy with the real thing.

My wording could be a bit misleading. This smallest particle must reside in space. There must be space, time is simply time and then we can also find particles that arise in space.

studiot Posted May 12, 2021 Posted May 12, 2021 Maxwell, Stokes and others worked all this out in great detail in the early to mid 1800s. But they rejected these mechanical models is unsatisfactory for a variety of reasons, and finally devised experiments to disporove aether models once and for all. How much less satisfactory do you think we now find them 150 years alter, armed with our greater knowledge and many, more refined experiments ? 2

Both depend on one another and either would not exist without the other. Space and time are interchangeable...hence the notion of spacetime. So no, its not a mistake. The fact that two people in two different FoR's, will not agree on a particular distance or on the rate of change [time] supports the model of spacetime and the fact that Intervals of space and time when considered separately, are not the same for all observers.

MigL Posted May 12, 2021 Posted May 12, 2021 If you invested as much time trying to understand accepted science as you have wasted on this useless conjecture, you would be that much further ahead, and have a good base to build on. Space-time has no associated 'fabric', nor can it be pushed or pulled. Stop wasting your time. 1

My position on this would be the same as Nikola Tesla: "I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view." - Nikola Tesla Anyone who think from the perspective of Space-time, are wasting their time. -2

Not at all. The vast majority of professional cosmologists hold that view, and it is supported by the evidence. While Tesla made some notable discoveries, he was also some what eccentric.

kai00 Posted May 13, 2021 Author Posted May 13, 2021 Not everyone agrees with Einstein. I think someone will disprove his theory within this decade. Tension would be a parameter of the equation and we will also end up addressing an expansion and contraction of a field. Further, the universe itself must be expanding and contracting.

Empty or free space has a measurable electromagnetic impedance of about 377 Ohms. Edited May 13, 2021 by studiot

joigus Posted May 13, 2021 Posted May 13, 2021 Just to add to the mountain of very sound objections. I'm curious: How do you explain muon decay as a property of chains of protons? What about mesons? What would Tesla have to say about that? 1

It is even used to make GPS work in our phones. Being a chemist, I have not learnt tensors so I don't pretend to understand the maths of GR, but I have learnt enough science - mainly QM - to appreciate that the way the universe works is not always intuitive and can be at variance with what everyday "common sense" may suggest. And non -Euclidean geometry is not that hard to grasp, in principle, at least.
