Is it rational (for an athiest) to believe in religion?
Yes, but I'm talking here only about believing in something, not about practicing something. P.S. It is my opinion, not a belief.

IMO, atheists also don't believe in god-like humans, "teachings", holy books, sacred texts, etc.

They are mutually exclusive to me.

Also, their chemical composition or metallicity.

Does modern physics support solipsism?
No.

The Ambiguity Thread
It ^^ is interesting but I don't think it fits a definition of ambiguity. There are many words that sound the same in different languages, but have different meanings in them. With a little work, one can make short sentences out of these words. Or, a joke. One of popular jokes among Russian speaking immigrants in Israel was to write back to there Russian friends a sentence which in English means, We live in a hole and swim in a pit. It works because Russian word for 'hole' (дыра) is the same as Hebrew word for apartment (דירה), and Russian word for 'pit' (яма) is the same as Hebrew word for sea (ים). We get new effect by mixing languages.

If I was able to live for millions of years
To be able to live for millions of years while interacting with environment, you'd have to evolve. It wouldn't be a Darwinian evolution, but rather evolution in a generic sense of changing in time. Simply because the environment changes in time.

The Ambiguity Thread
Of course, I'm not the first asking this question. Here is a 10 years old article, The advantage of ambiguity in language -- ScienceDaily. The opinion of these MIT linguists is that a context disambiguates well enough, so that a language can reuse some parts: "once we understand that context disambiguates, then ambiguity is not a problem -- it's something you can take advantage of, because you can reuse easy [words] in different contexts over and over again."

Forces
The so called centrifugal force acts like a gravitational force, or a horizontal component added to the Earth gravitational force. The rest goes according to Archimedes.

Cosmic rays and earthquakes
Their picture is that movements in the core cause changes in both the gravitational field and the geomagnetic field. The changes in geomagnetic field affect the cosmic rays behavior very fast. The changes in gravitational field affect the movements in the crust, but this takes time, thus the two weeks delay.

Cosmic rays and earthquakes
In this study the authors found a significant correlation: global strong seismic activity followed about two weeks after detection of variations in cosmic rays. Causal connection is not clear, but the authors suggest either effects of massive movements of the liquid iron in the Earth core, or some effects of the Sun. They have noticed some additional correlations and periodicity, but these need more data.

Forces
Perhaps you could measure this by displacement in a liquid that doesn't dissolve them.

A head of a 4,500-year-old statue found in Sheikh Hamouda in Khan Younis
It is interesting that finds like this still happen, in a long and densely populated place, in an agricultural field rather than under some old construction... Plus, I drove through Khan Younis 40 years ago... Palestinian farmer finds 4,500-year-old statue of a goddess while working his land - CNN Style

The Ambiguity Thread
AFAIK ambiguities exist in all human languages. I wonder, is it a bug or a feature? Or, maybe, a side effect?

Forces
It is effect of buoyancy. If it floats, it will move to the center. If it sinks, it will move outside.

The Ambiguity Thread
More "textbook" examples (from Yule, George. The Study of Language) : Time flies like an arrow; fruit flies like a banana. Annie bumped into a man with an umbrella. Their child has grown another foot. I once shot an elephant in my pajamas. How he got into my pajamas I’ll never know. (Groucho Marx) These are designed for small boys and girls. The parents of the bride and groom were waiting outside. The students complained to everyone that they couldn’t understand.

The earliest known technical manual in English
In about year 1400, Geoffrey Chaucer - yes, the poet - wrote a step-by-step guide, A Treatise on the Astrolabe, where he described in a clear, technical prose the use of the instrument, to his 10 years old son! A Treatise on the Astrolabe (chirurgeon.org)

It can be interpreted - as intended - that Navy used laser to shoot down drone. But it also can be interpreted that Navy shoots down drone which had a laser on it. Here is a snapshot from an MIT lecture with a similar example.

(This is OT, but the previous comment is so too) The title is a textbook example of language ambiguity.

Trolling (split from Quick Forum Questions)
Exactly. I have to answer to my conscience only. I can express my POV, if I want to. I can learn POVs of others and understand them, if I want to. There is nothing more can be done about them. If another person doesn't agree with my POV, it is not because they don't understand it, but because their POV is different. So, there is no point in explaining my POV again and again, is there?

Why do we need a graviton?
This relationship is needed because fields and particles don't only exist inside a curved spacetime, but they tell spacetime how to curve.
