Ther is a saying that "medicine is what we do to entertain the patient while nature takes its course".
There is.
And it's not said by the people who need antibiotics for sepsis or proton beam therapy for cancer, or even by blokes looking for viagra.
That's because it's actually wrong.
Raising  it here didn't really help.

If so, please provide a plausible explanation for the outcome.

Fake --like the photographs of the Milky way galaxy and Cavendish's experiment or this doc.--->
How did you come to the ... strange... conclusion that my mother's cancer remission was like a photograph of the Milky Way?

Or were you just trying to obscure the fact that you were calling me a liar?
That sort of thing doesn't go down well on science pages.

I did.
You wrote stuff that shows that you don't understand science again.

Now try to answer the questions this time.

The photographs of the Milky Way galaxy contain the Sun and the Earth that would require the photographer to be many millions of light years away from the earth which proves the images of the Milky Way were fabricated.

Do you accept that I can photograph the milky way through the branches of a tree?

Do they? Where did you get this information?

Please keep in mind that images depicting the entire Milky Way galaxy are not photographs. They are either artistic depictions or computer-generated imagery. This is one such example: https://solarsystem.nasa.gov/resources/285/the-milky-way-galaxy/

There's another copy of that video on line which claims to be the "full version".
But, unlike real BBC documentaries, it doesn't have the closing credits or a copyright message.
Is there any reason to believe that it's produced by the BBC?

Nice pictures of the Milky Way and trees, BC!

Here is another gallery of the Milky Way and houses.

The other source of images supposedly of the Milky Way from outside the Milky Way is to repurpose or adapt photos of other galaxies - there are a lot to choose from!

Because I'd like to know why he thinks it's true.

Did anyone say that they were?
That's silly.
The photographers were on the Moon, not millions of light years away, but about  1 or 2 light seconds away.

Quote from: alright1234
protons that have a mass 1,000 times greater than an electron would destroy human skin, bone and tissue in the path of the proton beam
The problem with electrons is that they are so light. I would expect an electron beam to be severely attenuated and scattered by passing through air, and it would be stopped by skin, causing surface damage but nor reaching a cancer.

The odd thing about proton beams is that they cause relatively little damage while they are traveling near the speed of light
- So they don't cause much damage before they reach the cancer.
- But when the protons slow down, they deliver almost all their energy (and damage) in the last few millimeters of their journey. This is called the "Bragg Peak".
- They don't continue onwards to cause damage beyond the cancer.
- This is much more focussed therapy than X-Rays, as illustrated in the graph in this Wikipedia article (Gamma Rays, also being highly penetrating ionising radiation, would be similar to X-Rays in the amount of damage they cause before and after reaching the cancer)
See: https://en.wikipedia.org/wiki/Proton_therapy

It is more likely that mass-less gamma rays are producing the effect of proton beam therapy since protons would be stop at any physical barrier such a the glass cover of the machine.

You missed the part where I explained that you can't accelerate gamma rays with magnetic fields...

Obviously, medics looked at using (cheap and simple) gamma sources, and found that they were of limited efficiency.
And the patient outcomes are better for proton beam therapy.
So how do you explain
(1) the difference and
(2)  how come they chose to do the difficult expensive thing?

Incidentally, this "protons would be stop at any physical barrier " is factually incorrect, so you can not rely on it as teh basis for an argument.
Well, you can, but you look a fool.

You can't liken protons to atoms. Remember when I told you just how much smaller protons are than atoms?

Protons, electrons, atoms, molecules and ions cannot propagate through glass without producing a hole in the glass.
