The official TFES model of the cosmos says that light is bending upwards. The article argues that there is no reason to assume that light travels in straight lines, and that curved lines are more natural in nature.

The Double Slit Experiment has shown that light exhibits wave-like properties and discredits the old idea that light exists purely as discrete particles. Not only has it discredited the old particle theory of light, but it also appears to discredit the axiom that light travels in straight lines. In these experiments it is seen that wave interference produces curved paths.

De Broglie–Bohm theory

The De Broglie–Bohm theory in Bohemian dynamics postulates that the destination of individual photons in the Double Split Experiment is not purely probabistic as some speculate, and an actual configuration of particles exists. When the trajectories are mapped out, it is seen that the light makes these jagged curved paths:

it also appears to discredit the axiom that light travels in straight lines.

But that isn't an axiom. Or rather the exceptions to it - light's path being affected by things like diffraction, refraction or spacetime curvature are well known and understood. The concept of light bending "upwards" is a bit meaningless in mainstream science. What does "upwards" even mean? That word is only meaningful in relation to your position. "Up" in Australia is a different direction to "up" in the UK - in the globe earth model.
I'm not clear what your actual point is here.

This is not understood. In this case with the Double Slit Experiment the light isn't being affected by anything at all. If one photon is fired at the slits at a time it will will take one of the curved paths of light and make the wave pattern in sequential dots on the screen destination at the end.

https://www.imperial.ac.uk/news/244037/double-slit-experiment-that-proved-wave-nature/

"Even when researchers fired just one photon at a time, the interference pattern still emerged, as if the photon split in two and travelled through both slits."

Aside from those who say that "it's being affected by phantom light in a parallel dimension that went through the other slit", it is not explained. Individual photons inexplicably make those curved paths all on their own.

I'm not clear what your actual point is here.

The point is clearly that it is wrong that light travels in straight lines. Light travels in curved lines. As mentioned above, a single photon can travel on a curved path on its own without any known influence.

[AATW]

If one photon is fired at the slits at a time it will will take one of the curved paths of light and make the wave pattern in sequential dots on the screen destination at the end.

You didn't need to provide a source for that, the double split experiment is a well known demonstration of quantum theory.
The really weird thing about it is if you put a sensor at one of the slits to detect which slit the photon is going through then the interference pattern disappears and they start acting like particles again. This is a weird, but well known phenomenon

The point is clearly that it is wrong that light travels in straight lines. Light travels in curved lines.

It travels in straight lines unless...
And the unlesses are well known. This is like you hearing Newton's first law of motion - that objects remain at rest or continue at a constant velocity unless acted on by a force - and then rolling a ball, noting it stops after a time and saying "haha, see?!". No, don't see - there was a force acting, friction.

As mentioned above, a single photon can travel on a curved path on its own without any known influence.

While not being an expert in quantum mechanics, I don't think that effect is because of the photon travelling on a curved path.
It's because of  the photon acting like a wave and going through both slits at the same time and interfering with itself.
As I said, it stops happening if you observe which slit it goes through.
A weird, but well understood effect in quantum theory.

Refraction is well understood too and Einsten's theory about light being affected by gravity has been verified experimentally during eclipses and gravitational lensing is used in astronomy.

None of this is the gotcha you seem to think it is.

[Tom Bishop]

Considering that there is more than one photon which the sun and all light sources produce, any point made about it only happening when one photon acts upon another or a photon acting upon itself, is fairly irrelevant. Light travels in curved paths.

[AATW]

any point made about it only happening when one photon acts upon another or a photon acting upon itself, is fairly irrelevant.

It doesn’t only happen with one photon. That’s not what I said. It’s the fact it STILL happens with one photon at a time which is the weird thing, and that it stops happening if you observe which slit the photon goes through

Light travels in curved paths.

Incorrect. The interference pattern only happens because of the slits and the wave behaviour of light when going through small apertures.

[Action80]

I do not know how you can claim the interference pattern only happens because of the slits without observing it to be the case.

I noticed that as a kid with bad eyesight. I discovered that if I looked through a pin-prick hole in a piece of paper, it brought things into focus.

If light naturally travels in curved paths, why do we observe straight-line propagation in everyday experiences like shadows and laser beams?

[alpha07]

Light generally travels in straight lines in a vacuum, as described by classical optics. However, in the presence of strong gravitational fields, general relativity predicts that light follows curved paths due to spacetime curvature—an effect observed during solar eclipses when starlight bends around the Sun. Atmospheric refraction can also cause light to curve, altering apparent positions of objects near the horizon. The context of the discussion matters when considering whether light ‘naturally’ curves.

[William87]

In flat spacetime, in a vacuum light, will always travel in a straight line.

Light doesn't accelerate, it travels at a constant velocity.  Constant velocity = straight line motion in flat spacetime.  Acceleration=curved line motion in flat spacetime.

Edit:
From the wiki:

The Electromagnetic Accelerator Theory calls for light to be "bent" upwards as it travels towards the earth. The path of light is a parabolic arc. It is commonly abbreviated to EA.

The only way light could be traveling in a "parabolic arc" is if it is traveling through a curved space. And if it is traveling through flat space and deflected by the motion of an object, it is deflected in the opposite direction of the motion.

In other words, if light, which is not accelerated and therefore, by definition, moves in a straight line in flat space time, is deflected by the upward acceleration of the earth, the path of the light wouild angle down, not up and would continue in a straight line, just at a different angle.

To answer this intriguing question, I'll provide a quote from a renowned physicist that directly addresses the nature of light's path.



> "Light travels in straight lines in a homogeneous medium. However, in the presence of gravitational fields or through media with varying optical properties, light can indeed follow curved paths."

— Derived from Albert Einstein's insights on general relativity and optics


This quote captures the nuanced understanding of light's behavior. While light typically moves in straight lines through uniform environments, Einstein's theories of relativity reveal that gravitational fields can bend light's trajectory. This phenomenon is most dramatically observed during solar eclipses, where starlight appears to bend around the sun's massive gravitational field, confirming Einstein's predictions about the curvature of spacetime.

Some real-world examples of light following curved paths include:
- Gravitational lensing in astronomy
- Light bending through optical fibers
- Refraction of light through different media like water or glass

Would you like me to elaborate on any of these fascinating aspects of light's behavior?

How is that light bending upwards accounted for in the Bishop Experiment or the Bedford Level one, out of interest?

[Pete Svarrior]

How is that light bending upwards accounted for in the Bishop Experiment

In the Bishop Experiment, light bending upward would make the results more damning for RE than if it travelled in straight lines. For RE to have a chance, light would have to bend downward (which, of course, is the ad-hoc explanation RE'ers provide)

[William87]

Isn’t light bending down one of the pieces of evidence you use to support UA because that is what would happen in an upward accelerating elevator?

Gravity is often described as an attraction between masses. However, the Equivalence Principle demands that photons, despite being mass-less, will seem to fall to earth[ like other bodies; exactly as if the earth were accelerating upwards.



If light curves up on a flat earth accelerating up, and down in  gravitation field, where is the equivalence?   The EP doesn’t just suggest that light could curve down, or allow it to curve down...it demands that it does according to the wiki.

[AATW]

How is that light bending upwards accounted for in the Bishop Experiment

In the Bishop Experiment, light bending upward would make the results more damning for RE than if it travelled in straight lines.

OK. I just asked how the bending is accounted for in the experiments.
I mean, cards on the table - I'm pretty certain the Bishop Experiment never happened. I don't believe the results he claims are possible on a flat earth let alone a globe.
At best he made a mistake in terms of what he was looking at and how far away it was.
But I was just asking whether he accounted for any light bending or pre-supposed that light travels in straight lines.

For RE to have a chance, light would have to bend downward (which, of course, is the ad-hoc explanation RE'ers provide)

It's interesting that you call refraction an ad-hoc explanation when it's a well understood phenomenon which you demonstrate with experiments in school. Well, I did.
The refractive index of different materials is known and can be plugged in to equations to predict results.
I'm not clear why you have an issue with that when you seem content with EA - the equation shown on the Wiki has no derivation given and has a constant with an unknown value.

Predicting exactly how much refraction there will be in the atmosphere is trickier of course. Tom has posted timelapse videos showing how refraction changes during the day as atmospheric conditions change. And yet claims that:
"Provided that there is no fog and the day is clear and calm, the same result comes up over and over throughout the year."

[Pete Svarrior]

OK. I just asked how the bending is accounted for in the experiments.

I would expect that it isn't - those are typically the stuff of more classical FE'ers, and you're asking about EA models.

I mean, cards on the table - I'm pretty certain the Bishop Experiment never happened. I don't believe the results he claims are possible on a flat earth let alone a globe.

I mean, it's a fairly easy one to do if you live near a body of water. I've had decent success looking at the coast of Normandy from Alderney. Now, it was more like 18.5 kilometres rather than 23 miles, so it's an expected drop of "only" 27 metres - but that's still 27 metres of height that my sight line somehow overtook. For someone who really likes accusing others of being lazy, you're really unwilling to do anything.

I'm not clear why you have an issue with that when you seem content with EA

I don't have an issue with refraction as a concept, but that doesn't make your flippant use of it any less an ad-hoc explanation. You take a variable phenomenon, declare without evidence that the variables must have just magically aligned for different conditions every time someone has replicated an experiment, and you consider the matter closed. I'm just not happy with such lazy shallow-mindedness.

[Tom Bishop]

AATW believes that everything that contradicts his model is an optical illusion except for those long distance sinking observations which he claims without evidence are not. 

[AATW]

27m given a viewer height of 0. With a viewer height of 1m it's 17.5m, 2m it's 14m. And that's without refraction.
Obviously I don't know the details of what you did, what you were looking at, what the atmospheric conditions were.
What I do know is I've seen a load of images said to be "gotchas" and "proof of FE" and they are all people making basic mistakes like:
Failing to take viewer height into account.
Failing to take refraction in to account.
Misidentifying what they're looking at and therefore how far away it is
Not accounting for the fact that the distant object is not at sea level.
Not acknowledging that the bottom part of the object is missing.

For someone who really likes accusing others of being lazy, you're really unwilling to do anything.

Similar answer to the one in the thread about space travel. I'm not the one who feels like I need to test anything.
The shape of the earth has been known for millennia. If there was any lingering doubt about it, which there wasn't really, the pictures and footage from the space race, and the emergent technologies like GPS and Satellite TV put and end to that. I've seen enough timelapses of boats going over the horizon, the claim that some make that if you zoom in you can see them again is clearly untrue. A friend who is in to sailing has told me how distant landmarks emerge from over the horizon top first.
I've never seen any timelapse of a boat going out to sea and just getting smaller and smaller until the optical zoom fails to resolve it.

All that said, on occasional trips to see family near the coast or on holiday I've done a few slightly half hearted tests but never well enough to find anything that conclusive.

I don't have an issue with refraction as a concept, but that doesn't make your flippant use of it any less an ad-hoc explanation. You take a variable phenomenon, declare without evidence that the variables must have just magically aligned for different conditions every time someone has replicated an experiment, and you consider the matter closed. I'm just not happy with such lazy shallow-mindedness.

I'm not really sure what you mean by this. Tom has posted timelapse videos of it varying over the course of a day - while claiming he can replicate the Bishop in varying conditions: "Provided that there is no fog and the day is clear and calm, the same result comes up over and over throughout the year".
He's not shown any evidence that he's done this at all, let alone that he can consistently repeat the results. His (correct) claim that refraction is variable demonstrates that his other claim about consistently being about to reproduce the results is impossible.

Obviously if someone presents a photo like the black swan you can't really know what the atmospheric conditions were like when the photo was taken. Maybe if you look in to where and when it was taken you can approximate it, but it's impossible to be that accurate. But the you can infer the conditions from the photo. The photo IS the evidence.
Now, if someone showed me a photo which is completely impossible on a globe, something no amount of refraction or accounting for viewer height and so on could explain, then I'd take that seriously. I just haven't seen it yet.

[Tom Bishop]

It's possible that there is refraction over the Monterey Bay, but I have never seen it. It's a bay attached to the ocean with the distant target at a location where people are just resolvable by a high powered telescope. If there is disturbance in the air over the bay it is likely to build up to fog over the ocean environment. So there is either ocean fog, or it is clear.

AATW is well aware that the Flat Earth effect has been observed many times. There are probably over 500 videos of this observation on Youtube and throughout the Flat Earth streams. My observation does not need to be videotaped, and I don't live in that area anymore.
