Gravitational waves in Newton theory are 4-th order, in Einstein's are 2-nd!!!

As Revoltingest kindly explained, this is an "a priori" truth. 1+1=2 is self-evident. Experience is not necessary to know it is true. It is true simply because of what "1" and "2" signify.

A priori
knowledge or justification is independent of experience, as with mathematics (3 + 2 = 5), tautologies ("All bachelors are unmarried"), and deduction from pure reason (e.g., ontological proofs).[3]
I can not see here the dis-proof of the trueness of the sentence "All bachelors are unmarried", can you?

No one can. It is an a-priori truth in that it is true simply because of what the words mean. It is impossible to disprove an a priori truth.
More significant than not being disprovable is that it can be proven true.
Can't do that with a posteriori thingies.

So, there are some formulas in Scientific books, that have no doubt accompanying them. Nice to know.
Of course not. Where did you even get that from? What a silly thing to say.

1+1=2 is not a formula. It is a mathematical equation. There are mathematical equations in math books that have no doubt accompanying them, sure. But, formulas and theories in Scientific books will always inherently contain some doubt.

Anything based upon observation (inductive reasoning) will have some level of doubt.
But things a priori, are without doubt....but doubt arises in applying a priori models to
the natural world.
To restate....the models are "true" because they're based upon axioms.

Example.....
10 - 1 = 9
This is true, based upon the axioms defining the numbers & operators.
But in the real world, this model doesn't always apply.
Consider 10 birds on a branch.
Shoot one....how many are left?
None, because the other 9 heard the shot, & flew away.

For your information: math is a respectful Science branch. Even Physics uses results of Mathematical Science, so, provided, that previous steps in Physics paper are true, the mathematical conclusions in Physics are doubt-free.

The Science is Quest for Knowledge, so if there is no dogmatic knowledge, then there is always a doubt. Doubt = No Knowledge, No Knowledge - No Quest for Knowledge, No Quest - No Science.

Nope.
Math is a tool and an academic discipline. But it is not a branch of science.

No one who understands the basics of the concept of science would ever say such a thing.

Total nihilism. The atheism, is the absolute solipsism, because word "Reality" is defined as "Reality is what comes from God." Do you have alternative definition?

Reality is the totality of all things that have objective existence.

God doesn't have objective existence. God exists only in the imagination of individual humans.

NEWS 2017: Nobel Prize for proving of Gravitational Waves!

Take the Newton's theory. Two masses of detector (m, m) are connected through an elastic material (which length is L), the source of gravity is in r meters away (and has mass M) and has the size X.
Then the force, which is expressed on receiver is:
F = GmM/(r-L)^2-GmM/r^2. Now, the source is vibrating with amplitude X. Then, the force in receiver is vibrating with amplitude dF = d(GmM/(r-L)^2-GmM/r^2)=-6 GmM L X/(r^4).
Its the 4-th order gravity wave. There can not be infinite speed in nature (because can not be measured), so the gravity wave propagates with finite speed. All that could be realized already by Newton.

The General Relativity adds the 2-nd order vibration, so, finally the vector of stress, expressed on detector is

dF=-A 6 GmM L X sin(t)/(r^4) + B sin(t)/(r^2),

where A and B are two different constant vectors.

P.S. Give likes also to my post about methodology of Science:
Who has changed the unchangeable Laws of Nature? Lawmaker. Can we call this lawmaker "God"?
There never was "laws of nature". it's right about here, where science and religion spin into la la land together, like a dance between two delusionial lovers.
