A true Scotsman doesn't buy it, he makes his own. Didn't Scotty 'invent' that on Star Trek: The Voyage Home ? ( where they go back to the 20th century with a Klingon ship to pick up a pair of whales )

There may be a few of us ... What would you like to discuss ?

My cat was sitting on my lap while I wached the video. She was licking her lips the whole time. Very nice, Moon.

Ah, memories ... I remember doing a simplistic Millikan's oil drop experiment in high school, and a much more elaborate one in 1st year Uni. Or maybe, it was being in my late teens that I remember fondly.

Found this article, which makes for interesting reading, and touches on many of the points brought up in this thread ... Barbara Kay: Transgender weightlifter may expose the unfairness of trans athletes in Tokyo (msn.com) that is , assuming the Tokyo Olympics actually take place.

If I tickle you, can you keep from laughing ? if you stick your finger down your throat, can you keep from throwing up ? Can you stop a sneeze, or touch a hot object and not recoil your hand ? Do you automatically yawn when you see someone else yawn? You are more 'hardwired' than you think.

We are also 'hardwired' to be very competitive, belligerent and tribal. This instinctive behavior is also evident in chimps. But we have come to realize that certain instinctive behaviors are detrimental to out society, and we try to control them with education, and laws, where needed. Similarly, child rearing is beneficial to our society, and birth-mothers/fathers provide the best care of their own offspring. Sometimes, 'natural' behavior is not the best option.

No moral judgement implied; just concern for your well being 🙂 .

Should you be buying stuff when you have no idea what residue it might contain ? ( even glass will absorb some chemicals ) Especially if you intend to use it as a 'bong'.

Sooooo ... Did you wanna discuss science based on observational/experimental evidence and available theory, or, your beliefs and imagination ?

Normally that wouldn't be requred, as you seem to have an excellent understanding of the Physics involved. However, Awaterpon might not even be convinced by the 'brute force' method of everyone else on the Forum presenting valid evidence contrary to his calculations.

Quite often it is the perception of an opinion, or event, that politicise that opinion, not the intent of the people offering the opinion.. This might have more to do with a perceived inequality of opinions/articles, by you, where none actually exists; IOW,look in the mirror. As for the origins of SARS-COV2, by all means, it needs to be investgated; It is certanly fair to criticise the Chinese government for their actions ( excessive secrecy, human rights violations, predatory economic policies, 'bullying of other nations in SE Asia, etc ), but not of Chinese people.

What do you mean '1 kg pushed the 4 kg' and the other '1 kg went away' ??? That is not conserving momentum. The 1 kg that goes along with the 4 kg is not pushing it ( that makes no sense ). Momentum conservation demands that, as a consequence of the 1 kg 'going away', the 4 kg +1 kg has to go in the opposite direction at about 1/5 velocity ( modified by the Lorentz factor at relativistic speeds ). that is how a rocket works.

Even if your mathematical model was found to be self-consistent, there is no guarantee that it is actually applicable in any/all circumstances. The mathematical model has to describe a physical system, so don't go jumping to conclusion regarding applicability to BHs, Hawking radiation and the 'information paradox'. Even GR is not applicable in some circumstances, as evidenced by the un-physical singularities it predicts.

Any disturbance in the atmosphere will propagate at the speed of sound. If the disturbance is moving towards/away from you, there will be Doppler effects. If the disturbance is moving towards you faster than the speed of sound, you will not hear it until the leading shock and disturbance arrives. Your question, as it is, seems to be 'ill posed', and I don't see what conclusions/insights you can draw from it. ( at least, pertaining to Relativity, which is your usual area of interest )

We've heard you mention 'your theory', now, for several days, yet most of us don't have a clue about it. The only thing we know is that it failed a previous peer review, and none of us are going to your link, to read and try to understand what could be 400 pages of garbage. If you want people to discuss 'your theory', post a brief description here, and we will be glad to dissect and critique it ( even if you don't like our criticism ); otherwise quit bringing it up in multiple threads. IOW, put up, or shut up !

What do you mean by 'two' explosions ? There is only one explosion resulting from their collision, and because your ears are 8 in. apart, you will be able to discern the direction it is coming from. If there are two explosions resulting from reasons other than a collision ( ?? ), then the explosions are spatially separated, and will arrive at your ears at different times. These are common, every day occurrences, and readily apparent. Either that, or I'm totally misunderstanding the question.

I've been using the free version of Ccleaner for almost 15 years ( introduced in 04, I believe ). I run the system cleaner every time I shut down one of my computers ( about 18, all Win10, except for one Raspbian running RetroPi for old games emulation ), mostly to clean out cookies, and never had an issue. I run the registry cleaner ( all boxes checked ) every time I install/uninstall software, or MS updates me, and again, I've never had an issue.

Your ears can 'locate' the origin of sounds because the sound has to travel different paths to your two ears. Unless you are V van Gogh, I would think this is apparent.

Download the free version of Ccleaner. Download CCleaner | Clean, optimize & tune up your PC, free! and let it do the clean-up.

IIRC, the 'doomsday clock' originally ( since 1945 ? ) considered only nuclear armageddon, but now includes many other threats to human existence. These other threats, such as Global Warming, global viral Pandemics, water and food shortages, etc., not only add to each other, and the overall threat level, but some of the threats are 'caused' by some of the others. Overall, the OP seems a 'glass half empty' excuse for a rant. Now is not the time for people to 'lose their sh*t'; it is a time for deliberate and calculated decisions. With a little 'glass is half full' optimism, good will, and the right decisions, this truly is a wonderful time to be alive.

Why don't you post the ingredients list of the salt you used, so we can possibly eliminate the salt as the source of the discoloration ? Better yet, why not be a good Italian, and stick to 'vino', rather than craft beers. I recommend a nice, and very drinkable, Aglianico from the Irpinia ( Campania ) region.

And I thought I lived in a rough neighbourhood. Always thought Iowa was a calm, almost boring state.

Evil is a social construct, and, while social behaviour is an evolutionary effect, there is no evidence that its constructs have have an evolutionary cause or impact. Not everything has an evolutionary aspect; some of the sh*t, we just made up.

The speed of light barrier is a 'bummer'. So much so that people, even scientists, are grasping at straws, trying to find ways around it. The 'semantic' approach notes the difference between moving through space, and moving with space. And it results in more problems than it solves.
