Oh, all right. I'll let you in on the secret. Sssshh.

Write4U posted something about a "vacuum singularity" which is not a term I am familiar with so I asked him what it meant.

Does that make sense or do you need it in Japanese?

Thanks for the tip.

The term circadian comes from the Latin circa, meaning "around" (or "approximately"), and diem or dies, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.

Would the circadian rhythm be altered by a change in sunlight pattern? I.E, the month of darkness in the northern regions of Canada?

It might be ignored if you take a somnolent perspective on it https://en.wikipedia.org/wiki/Somnolence

Correct.
Because you will not, or cannot, support your assertion that "information exists physically in some form".

Information always exists physically if it exists at all. Choose any form of information storage you want, you will inevitably find that some material object has to be in some particular state in order to store it. If it's in your brain, then some of the cells in your brain are in some particular state, or else you would immediately forget it.

Interesting question. Probably this is the only situation where the OP would make any sense. An object with no substructure, all alone in the universe.

Would time pass? I'm going to go with "no". The reason being because there is no "aether", so there's no absolute measure of distance or motion. Without a second object, any claim that the photon is "moving" makes no sense. Also any claim that it has a particular wavelength is meaningless, because there's nothing against which to measure "length".

How can the glass be filled with a vacuum and we say it has nothing in it? The way I posed the question might be a bit misleading but I have no other tool to explain. Can we say vacuum is nothing? Or can we say the glass is empty? At least its empty of air. What is emptiness, and what is the void? Do you see what I am saying?

Filled with vacuum is as "empty" as anything can get.

It's an interesting thought experiment to ask ourselves what a glass with nothing, not even vacuum would be like, but..... how would you remove the vacuum? There doesn't appear to be any such thing as any mechanism that could achieve that.

The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10−12) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. Some theories predict that even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, and other phenomena in quantum physics. In modern particle physics, the vacuum state is considered as the ground state of matter.

I'm guessing this is the basis of Therapy's objection.

Good Logic
