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.

A Science Illustrated article portrays curved routes:



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.

"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.

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.

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.
