No, it's not. Convergent evolution wouldn't result in identical species. But you didn't say anything about the same species emerging. The claim that "Nothing in nature is observered (sic) to happen again or twice ...have a look yourselves! " is not the same as saying some species would emerge twice. The former is very vague* and demonstrably false, while the latter is true and unsurprising, given what we know of evolution. * "nothing" covers a pretty wide range of items and phenomena. All of them, in fact. So as exchemist notes, processes repeat all the time, even if the outcomes differ.

No, it's the galaxies not bound to each other that will continue to recede from each other. The stars in these galaxies will burn out and eventually new stars will not be able to form. Redshift is caused by motion away. If the motion is towards each other, there will be a blueshift. There's also a redfshift as light climbs out of a gravity well.

Octopus eyes and human eyes are "wired" differently (humans have a blind spot); they did not arise from a common ancestor. Eyesight is something that developed multiple times in the course of evolution. It's not the only trait to have done so.

"impenetrable" implies there is something there that might penetrate. Again, this is treating nothing as a substance, which it is not.

Gravitationally bound systems don't expand. From the article: "we’re measuring the inverse-square law below the dark-energy length scale to look for a possible new gravitational phenomenon" (emphasis added) They aren't looking at distances where expansion is observed. They're saying that dark energy doesn't perturb gravitationally-bound systems.

Yes, semantics is a big part of this. Are we? Is nothing an object? There are a number of cases where a certain class of nothing is defined by something: a hole in the dirt is defined by a lack of dirt, dark is the absence of light. It's not an object, it is a state or condition. It's dark inside the box. Is it the same dark if you move it? Kind of nonsensical. The same condition exists, but the phrasing is treating it as an object rather than as a condition. Which makes is a bit of a silly semantic game, as people have hinted at or suggested in the thread. Which is why this is silly.

Dark energy causes accelerating expansion, which is not a part of Newtonian gravity.

No thing can enter the box is not the same as saying nothing can enter the box. Are we sure that nothing can't pass through the box? What if nothing can enter the box, and nothing can leave the box. How do you you check to see if this happens?

Small number. Which is perfectly consistent with there being a spectrum of attitudes on the topic. I'm on the part that dislikes sport fishing and tends not to kill spiders (at least, the ones that can't kill me, were I to be confronted with that scenario)

Infinite monkeys would re-write Hamlet in the time it takes a typist going at the same rate to type out Hamlet, per the link in the OP

It’s from Lockheed, so it’s equally reliable, but the accompanying text is “An F-35B test aircraft completes its first-ever vertical takeoff (VTO) at NAS Patuxent River, Md., on May 10, 2013. While not a capability used in combat, VTOs are required for repositioning of the STOVL in environments where a jet could not perform a short takeoff. In these cases, the jet, with a limited amount of fuel, would execute a VTO to travel a short distance.” IOW, little fuel and no combat payload. So in the context of the original claim that you could put these on a battleship as part of its battle capability, it’s not a VTO aircraft.

“Can land vertically like a helicopter and take-off in very short distances. ” STOVL, not VTOL Is Lockheed Martin a good enough source? https://www.lockheedmartin.com/en-us/products/f-35/f-35-about.html#b_stovl

Yes. The volume is defined by the box

“nothing” doesn’t have a temperature

What’s the reason to think you could launch/land an F-35 on such a vessel? F-35B is not vertical take-off. It still needs >150m of runway. https://www.thebaseleg.com/Features/F35b-sg/ https://aviationbuzzword.com/f-35b-at-sea-dont-need-no-stinkin-catapult/

PrimalMinister has been suspended for dredging up a topic they were told to avoid. But we will give them one more chance to make their case.

! Moderator Note After staff discussion, we have decided to give you one more chance to post your “theory” It must be posted in speculations and conform to the rules. Meaning you need to make sure your post is complete enough to contain a model and/or make predictions and be falsifiable, and provide supporting evidence.

I’m not sure impossible is disqualifying as a philosophy question.

Is the mass varying with position in the first example? If it is, then momentum is not conserved for the object, and we can confirm this with Newton’s laws of motion. There must be an external force on it. Is the mass varying with time in the second example? If it is, mechanics or relativity tells us that its energy isn’t conserved. There must be some interaction (e.g. work is done) to account for this. You wouldn’t be applying symmetry to these problems if mass were varying, as their Lagrangians are not constant, i.e. not symmetric under the relevant translation.

! Moderator Note You were unwilling or unable to discuss you “theory” with anything approaching scientific rigor, we’ve gone several rounds on this with no evidence being provided by you, and you were told not to bring it up again.

But when one puts a physics context on it, those familiar with physics understand what is meant, and it’s not the nothing described in the OP.

I think you need to ignore physics, because if you account for it, the concept of “nothing” goes away.

There’s no way to test an hypothesis of their origin (as exchemist say, there’s no observation to be made) and no way to model it. Models require rules.
