Vacuum is a kind of matter

Vacuum is not a void. Information can not be separated from the material carrier. Transmission of information using waves in a vacuum means that a vacuum is a kind of matter. If the vacuum is not matter, it means that information can be separated from material carriers. Physics has a good experience in the study of matter, but there are certain problems in the study of information. Vacuum is a kind of matter, devoid of substance. 212.115.245.17 (talk) 08:34, 24 November 2018 (UTC)

Got refs? To include that or redefine based on such would require WP:reliable sources. Vsmith (talk) 13:04, 24 November 2018 (UTC)

Reliable sources are a subjective concept. I have sources that are reliable for me. But I do not know if they are reliable for the rest. You can blame me, but Wikipedia has some known flaws, including an inconsistent system of rules. I had enough time to study this system and I know about the main drawback of the Five Pillars. Authority is not a guarantee of the truth of knowledge. The requirement of credibility does not guarantee improvement of Wikipedia articles (and this is the main goal). Science is an area where the minority prevails over the majority, so the right things can sometimes be perceived as marginal ... Here is one source (in Russian) https://storage.googleapis.com/dotu-154621.appspot.com/20040623-DOTU.pdf (see page 302, 336) or video lecture by Professor Zaznobin (in Russian) https://www.youtube.com/watch?v=d3mBP6Yl1Jg . Vacuum research is the forefront of science, so you are very lucky to deal with such information. 212.115.245.146 (talk) 19:31, 24 November 2018 (UTC)

Indeed, reliable sources are a subjective concept. That is why Wikipedia needs wp:Secondary sources. Also, by design, Wikipedia tends to shun the forefront of science—see wp:FRINGE and wp:UNDUE. If we like to deal with such forefront information, we need to go elsewhere. - DVdm (talk) 10:07, 25 November 2018 (UTC)

"Measurements relative to 1 atm" Section

This section has a few issues, such as its reference to Torricelli as if he hadn't been mentioned in the article yet, questionable grammar in the second paragraph, and no references given for assertions made. I thought asking for others to take a look might be a better idea than making changes. 2603:8000:BA00:4B00:7113:D829:1CAB:41E1 (talk) 04:16, 4 March 2023 (UTC)
