simple sentence. zero dimensional space
I wouldn’t waste time on it. It looks like the deranged ramblings of someone with mental health or drug problems. If they can’t be bothered to explain clearly, it is not up to others to spend time on it.

Unidentified DNA
Presumably this would require the lab to have access to a database of known species. Is that something that is readily accessible to most labs? Or just some more specialised researchers?
-
Unidentified DNA
It may just be that the lab doing the analysis doesn't have a sample from whatever species the hair came from (wether dog, pig, human or something else). Wouldn't they say "no DNA found" in that case?

Green Tea Turns Black After Adding Honey
I have noticed that some types and brands of green tea go brown quite easily. This seems to be more common with Chinese green tea (which I think Twinings is). And also seems more common with hard water and when the water is too hot (green tea should not be made with boiling water). Not sure why honey should make a difference. But many honeys are slightly acidic. This could well be a factor. Update: it is tea time so I just tried adding some honey to my green tea. It did not change colour. So there must be other factors at work. (Also: adding honey to green tea should be illegal anyway!)

Today I Learned
Today I learned that the word "cubicle" has no connection with "cube". It originally meant a place to lie down (still does for some people). https://www.merriam-webster.com/words-at-play/cubicle-cube-office-word-history-etymology

Today I learned that owl have really long legs (that they keep discreetly hidden) and that baby owls look just like aliens:

Today I Learned
I'm not sure where this should go so this seems as good a place as any... Today I learned that dinosaurs lived on the other side of the galaxy. This is a neat animation of the timescale of dinosaurs (and others) related to our orbit around the galactic centre:

Please show the calculations to support this. (You seem to have missed them out in the previous posts)

What is Space made of?
That is why science doesn’t really deal with “truth”. It creates useful models to describe the world. There can be two or more “correct” models of something, which may even contradict each other. For example, in Newtonian mechanics & gravity, space and time are absolute and independent. That model works really well. But in relativity they are relative measurements and interdependent. That model can give more accurate results in some cases. There are models where space and time emerge from something else. The model works. Using words like “mystical” doesn’t change that.

Do you have any evidence that those contribute to population decline?

Typesetting equations with LaTeX: updated
As noted in the first post, you can use math tags: [ math] y = x^2 [/math] => [math] y = x^2 [/math] or Inline brackets: \ ( y = x^2 \) => \( y = x^2 \) or Display brackets: \ [ y = x^2 \] => \[ y = x^2 \] (I have added some extra spaces to show the markup.)

Sun & black holes
Because the temperature is inversely proportional to mass (and the power output inversely proportional to mass squared) it will get increasingly hot as it shrinks. However, the lifetime of a moon-mass black hole is about 1045 years. Near the end of life, this will accelerate and it will explode in an intense flash. Scientists have been looking for evidence of the decay of primordial black holes (with no results so far). Handy black hole calculator here: http://xaonon.dyndns.org/hawking/ (you can provide any value and it will calculate the others)

Sun & black holes
We know how stars form: cloud of hydrogen starts to collapse, when it is dense/hot enough fusion starts and the radiation pressure stops further collapse (until the end of the stars life). Black holes are formed from stars, not vice versa

A New Theory of Motion and the Speed of Light
This sounds a lot like you are saying there is an absolute frame and that the speed of light is not constant in that frame. But it always appears constant. Does this mean that, in your model, it is actually impossible to detect this absolute frame reference? (And, again, I assume when you say "constant" you actually mean invariant. These are different concepts. It worries me that you don't know the difference.)

A New Theory of Motion and the Speed of Light
It is irrelevant. And not under anyone's control.
