Are all forces illusions?

Its like the "hidden" force, that pushes 2 people together, if they walk up from the equator, to the north pole, but 1 person starts here, and the other starts 100km further on the equator. They both walk up, in a straight line, but when they reach the north pole, they are magically "pushed" together. This is EXACTLY the same as gravity. The 2 walking people, were not pushed to eachother, thats an illusion. They walk on a curved surface in a straight line (a geodesic), and because of this curavture (just like spacetime is curved), they eventually find eachother at the same point, because of the hidden force "gravity".

Also, time really is just "forward". It literally is just "forward". Without time, the apple wouldnt fall down, it wouldnt walk forward on the curved surface.

WOW! That was the best explanation I’ve ever heard. I am still in shock

I must ask, why is that background sounder necessary? What does it add to the content? Why not turn it off?

The "push" felt by a passenger in a car has nothing to do with the ground. The passenger feels the contact force of the car accelerating him from rest. They infer a backward force because they are incorrectly using the vehicle as an inertial frame. They aren't feeling the ground pushing the car along.

Yes, but... when the car is accelerating, my body is pushed by a physical force. The seat is pushing me, being pushed be the frame, being pushed by the friction. It's not like a centrifugal force. I think ...

My questions:
1. Why would planet grow and space shrink?
2. Why do electron throw that photon towards another electron?

Why cant they be "relative"

If every event that occurs between objects in spacetime is relative, then it's all entirely based on perspective. We can never remove the observer from the equation in any instance of recorded experimentation.

Locality seems to be a fundamental law of nature. Basically there are only proximal interactions and actions at a distance are emergent phenomena.

You have to concentrate more when bg music gets change

why would anyone explain gravity as "earth's surface move outwards?" I know that you mentioned that it is flawed, but I fail to see how it would be an elegant answer
this confused me.

also why did we mention the force of the earth's core pressure as within the category of "gravity", when they are different kinds of forces?

also, why did we explain the "ball catch" as newton's third law, making it resemble collision or inertial illusion? isn't the reason why electrons repel each other is because this quantum exchange altering the very space and energy distribution around the electrons, subtly leading to their aversion to each other?

I feel like this video could be made much more intuitive, kudos on the great visuals though!

Excellent channel. 👌🏻

A force is motion, motion is the force that gives us what people perceive as gravity, our reference frame is in motion upwards relative to us inside the reference frame, this motion is what gives us our weight and the density layers and pressure gradients, to have a directional vector which we have means there’s motion, the antecedent to a directional vector is motion
Globe earth and flat stationary earth both need there to be an acceleration down towards the earth, this is their reason why objects appear to “ fall”
Fact is there is no acceleration down towards the earth, a simple accelerometer will displace when accelerated, when in free fall there is no displacement of gas and liquids so there can’t be an acceleration down towards the earth
Density and buoyancy aren’t a force unto themselves, density and buoyancy are an effect of motion, in free fall we become weightless, why, because we’re no longer attached to the reference frame which is giving us our weight , also in free fall density and buoyancy cease to exist, again why, and again it’s because it’s no longer feeling the effects of the motion
Einsteins equivalence principle had two postulation’s and only one can be shown in a real scientific practical way with demonstrations, gravitational fields don’t exist

Let's imagine replacing Earth with an empty thin shell of the same radius. Objects on the surface will experience only minimal gravity. Now let's move a black hole inside the shell, so that the total mass of shell + BH is equal to the mass of Earth. Objects will now experience 1g of gravity, but the surface will be the same as before.

I didn't understand the gravity part tbh.

You say that the earth is constantly expanding and thus touching the apple. But then the space around earth is contracting down to the core..

And there I lost my train of thought.

I left a comment criticizing this video a few years ago. I was wrong. I watched it again today and I 98% agree with what you say. I wish every physicist understood this. 100% yes!

Makes you think, did “gravity” exist first and matter simply accumulated in the condensing regions of space-time?

If we launched enough matter equating to half of earth’s mass into its orbit as space junk, would the moon’s orbit be unaffected because the space-time “fabric” is condensing where it is going to condense regardless of where matter is located? Or are we influencing the space-time fabric in a small way by consciously and actively moving the position of matter?

this explanation of gravity twists my brain. I've watched multiple videos of this in other channels 😂

So gravity isn't also a fundamental force with the other three ??
I thought there were 4 of em

no joke this gives me anxiety but love and peace, knowledge is power!

So my feet not fall through floor via light photons shooting between my skin and floor?
am i kind of iron man flying accelerated by light beams?

for the most part you were describing newtons third law and even tried to use it as an explenation to electrodynamics, though you never explained why the electron is pulled towards a proton. so forces are not illusions, counterforces arnt either. they are just physics

The whole "gravity is an illusion" thing kinda sounds like the electric universe theory to me. Especially when it's followed up with electromagnetism being on of the 3 fundamental forces of the universe

This is amazing, I always watch science videos, but this is the first time I have grasped an understanding of what field is, and gravity is. You videos are really great and simple to understand!

So if you squeeze a ball enough the atoms will come together and make a possible nuke? lol

Omg Finally i understanded the forces

It's not reasonable that the car's movement can influence the universe instantaneously? Yet, it's reasonable that entangled particles instantanously communicate with each other?

Very clearly spoken in understandable English.

So basically the whole universe is the newton's third law

Virtual particles aren't real though and are a tool. Feilds are the real answer

Eureka!!!!!!!!

If there are only 3 fundamental forces: the electromagnetic force, the strong nuclear force and the weak nuclear force then why do scientists still say that there are four fundamental forces in the universe including the gravitational force with the previous three forces? While it's clear that gravity is not a force but the motion of the space-time, scientists still trying to quantised it in the same way as the other three fundamental forces. Why?

So, the Newton's third law is the main hero of this episode.

alright, so if I understand this right:
the earth is both expanding outward and shrinking in. this is because the earth's insides exert an outward force? in an object where there isn't an outward force, say a cardboard box, it should just shrink? please explain how this works

Could those 'balls' be exchanges of plank packets of space time amongst the particles of a massive object as spacetime flows into the object and expands the objects proportionately?

can't even begin to remember how many tik tok edits of this channel there are

Gravity is not a force

Bruh…

Doesnt that mean every force is inertial? Since when you push a ball away from you you push yourself away from the ball. WHICH IS THE DEFINITION OF INERTIA

Can Newton's law of Gravitation is wrong?? Please reply

That depends. If forces exist from all frames, then its real. If forces exists in only specific frames, then it’s fictitious (fake).

But the earth is still technetically affect the apple without touching it, so is it fair to say gravity is both inertial and act at a distance?
