I have differences with a colleague over
the term “energy.” He believes energy to be equivalent to motion and considers
our differences to be mere semantics. I don’t think so. Astute followers of
this Blog know that I consider energy to be a matter-motion term. Energy is a
calculation. Energy neither exists nor occurs; energy is neither matter nor
motion.
He may regard energy as motion, but there are
others who regard it as matter:
NASA says that: “roughly 70% of the
Universe is dark energy. Dark matter makes up about 25%. The rest - everything
on Earth, everything ever observed with all of our instruments, all normal
matter - adds up to less than 5% of the Universe.” (http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/)
It is quite clear in this passage that NASA
regards dark energy as matter, in other words, dark energy is a thing just like
“dark matter” and “normal matter.”
So it certainly is not simply a matter of
semantics when the same term can be used for two different fundamental phenomena
by different people. I suppose that on Thursday, I could regard energy as
motion, and on Friday, I could regard it as matter. You could have some fun
with your modern physicist friends by asking them what energy is. The only
correct answer is that energy is a calculation: E=mc2, the physical
meaning of which I discussed in: http://scientificphilosophy.com/Downloads/The%20Physical%20Meaning%20of%20E%20=%20mc2.pdf.
This calculation, like other matter-motion terms such as momentum and force, describes
matter in motion. NASA’s imagery is of bare-naked matterless motion floating
around outer space—an impossibility. My friend should give up “energy” whenever
possible, like Steve and I did to great advantage in "Universal Cycle
Theory" (www.universalcycletheory.com).

The Blogger / Google login status, and the ability to post comments, is sensitive to both cookie and script filters. Your readers may need to enable (stop filtering) "third party cookies", in their browser and on their computer. The effects of the newly unavoidable CAPTCHA, and the Google "One account" login, requires third party cookies, even more than before.

Third party cookies filtering, in a browser setting, is the most common solution, overall - but your readers may have to search for other filter(s) that affect their use of Blogger / Google.
Any filters are subject to update, by the creator. If the problem started a few days ago, your readers may have to look on their computers, and find out what product or accessory was updated, a few days ago.
