With respect, I think your God discussions are more appropriate to the Theology thread. | ||
| Sami |
You were the first to bring up God, I merely followed upon what you said. | ||
| H0gwash |
Sure, but the others on this channel surely don't want to hear you try and convert me to Jesus again on an entropy thread. Open up another thread in Theology and they can watch us there if they want. | ||
| Sami |
Where did I try to convert you to Jesus? Where did I even mention Jesus? You were the one who first brought up God and Jesus in this thread, not me. | ||

Cool, Gerard. | ||

Squids, Check out enthalpy, emphasis on the 2nd syllable to avoid confusing with entropy, or so my thermodynamics professor said, and he literally wrote the book. Dr. Holman. I do my best at trying to be reversible and adiabatic. Not working out though. | ||

https://www.amazon.com/Thermodynamics-J-P-Holman/d p/0070296332 He also wrote two other texts of mine: https://www.amazon.com/gp/product/0073529362/ref=d bs_a_def_rwt_bibl_vppi_i1 https://www.amazon.com/Experimental-Engineers-Mcgr aw-hill-Mechanical-Engineering-dp-0073529303/dp/00 73529303/ref=dp_ob_title_bk Great professor. His son, Blake, was in the class one year behind me. | ||

Sami: Did you see where the Veritasium physicist released a video about the unknown speed of light? Love that guy. He's done a lot of exceptional work to help knock the public perception of "science" back to where it belongs. | ||

Blake, I haven't, got link? Regarding gravity, it is not a "force". Instead, gravity is an effect. Imagine riding a motorcycle and suddenly having to stop before a stoplight (deceleration). What do you feel? You feel your body being pushed forward for a second or two. That feeling is not a "force", it is an effect. Gravity is similar to that, it is an effect. The difference is that gravity is a persistent effect, whereas suddenly stopping before a stoplight is a temporary effect. But both are effects nonetheless, not forces. Scientists have complicated gravity beyond necessity. Unnecessary complication leads to unnecessary trouble such as having to find Shy Matter. Gravity can be suspended by electricity. More specifically, gravity can be suspended by magnetism. Electromagnetism is not a "force" either, it is an effect. Gravity and electricity are two sides of the same magnetic coin. | ||
| Sami |
The weak and strong bonds are not "forces" either, they are effects. The "attraction" between objects, such as protons and electrons, are effects resulting from a pressure differential. Nature abhors a vacuum, it tries to fill in any vacuum that might be present. Simply put, the four so-called "forces" are nothing more than nature filling in a vacuum. "Forces" are effects of pressure differences, or buoyancy. | ||

“ Gravity can be suspended by magnetism” No, it is countered by magnetism, or some other force. Say, the bookshelf something is on. Your airplane model still feels gravity while suspended in a magnetic field the same way you feel gravity while being prevented from falling by standing on the ground. The ground holds you up, it noes not suspend gravity. | ||

Are you self taught in physics Sami? | ||
| Aesquire |
No, it is countered by magnetism, or some other force. Say, the bookshelf something is on. Correct. It's an intriguing notion that force doesn't exist, that it's all "nature filling a vacuum" , but by the time you cancel all the philosophical elaboration, you still get F=MA. I assure you gravity is never suspended when I fly. Arguably I fly on solar energy mostly, but it's not the photovoltaic kind, it's indirect. Sun heats Earth unevenly, air moves. Soaring flight is fighting entropy with skill. | ||
| Hootowl |
Even on orbit, gravity is not suspended. In fact, gravity is required for orbit. | ||

You know: I had a hell of a time getting into this thread. I think it's winding down. Kinda like the Universe. | ||
| Sami |
Jeff, magnetism is not a force, neither is gravity. "Suspended" is a correct term to use knowing that these are not forces, but pressure differentials. The "downwards" pressure known as gravity is suspended, or alleviated, or as you prefer, countered by, in this case, an "upwards" pressure known as magnetism. No, we don't feel gravity. Rather, we feel pressure differences. That is basically what gravity is, a difference in pressure between different elevations. Patrick, mathematical equations do not tell us what gravity is. Instead, they tell us what occurs if X happens to Y given Z. I have no issues with F=MA, except to point out that we are not dealing with forces, but with pressures. Gerard: "Are you self taught in physics Sami?" I don't know what that means. If you mean that these are my own ideas, then no. I stand on the shoulder of giants.

Gravity is neither a force nor a constant. It is an effect of pressure. Understanding gravity as a pressure rather than as a force simplifies matter immensely. | ||
| Aesquire |
Pressure? Of WHAT? The aether? Gravitons? The Will of Landru? The repulsive waves from the edge of the Universe pass through matter in proportion to it's density. So "Gravity" pushes me down on my skin, and all the other cells in my body, to an unmeasurable difference in degree. ( or at least no one I know of has tried to measure it, so... ) This is assuming that Victor Appleton Jr. was an incredibly foresighted writer, who invented the Toms Swift Jr. Repellatron. | ||
| Sami |
No, it is countered by magnetism, or some other force. Say, the bookshelf something is on. Incorrect. The bookshelf (I have one standing next to me) simply provides pressure in the opposite direction to the downwards pressure known as gravity. On the microscopic scale, the atoms within the bookshelf "press" against the objects placed on them. Electromagnetism is another pressure effect. The so-called "fundamental forces" are pressure effects. | ||
| Sami |
Patrick, yes, pressure. Try pressing a ball down under water. What do you feel? You feel a pressure in the opposite direction pushing the ball back to the surface. There is no force involved, all that is involved is pressure differences. Let's see: Gravity Electricity Magnetism Weak Bond Strong Bond James Bond (joking) All these are pressure effects. | ||

Ah, but pressure differences of What? You confuse effect with cause, perhaps? My wing flies "because" of pressure differences. But Bernoulli's principal is a very incomplete view of what is actually happening. Just as the idea that a wing produces lift by changing the direction of the air. True, but incomplete. | ||

You’ve got some strange ideas, Sami. | ||
| Aesquire |
I get the metaphor, but it lacks substance. I had a lengthy diatribe, but my internet glitched and you've been spared it.  Seems like Sami is at the Demon theory of flight. Little drag demons hold you back, and little lift demons who like you lift you up, but don't insult them! ( you get the idea ) | ||
| Sami |
Patrick: "Ah, but pressure differences of What?" You've answered your own question: "I get the metaphor, but it lacks substance." Space is not empty, it is not a vacuum. There are quantum particles occupying space. Those particles constitute the substance responsible for the pressure differences induced by matter acting upon it. Jeff: "You’ve got some strange ideas, Sami." I get that often from people. But it's not strange, it's simple and sensible. "Forces" are untenable and result in "spooky action at a distance". | ||
| Aesquire |
No, telling me it's the whichness of when, or "what?" is me answering myself, is used beer. it ain't raining. Quantum particles? That's Ant Man & The Wasp technobabble and handwavium. We've got theories for both "transfer particles" and waves... Both may be vortices, but my microscope isn't good enough... | ||
| Hootowl |
“it’s simple and sensible” Occam’s razor isn’t always the right tool, especially if you’re a quantum mechanic.  | ||
| Sami |
Patrick, theories are insufficient to answer your questions. Sure, we've got theories, but theories are a dime a dozen. What is needed is not theories, rather what is needed is reason. Theories requiring empty space are faulty. Space is not empty, this has been observed beyond a shadow of doubt. If scientists claim that space is empty or a vacuum, then we know that they are wrong. If this Plandemic taught us anything, it is that scientists are wrong on many things. Scientists and their dime a dozen theories about gravity are not reliable sources for questions involving metaphysics. "Vacuum of space" is metaphysically nonsensical. Vacuums don't exist in nature. Space is not a vacuum. Nature abhors a vacuum. Motorcycles are proof of that. Under pressure, fuel is combusted which turns the wheels around making the motorcycle move forward. Pressure, not "force", is responsible for this action. |
