Is Gravity a Force?
Very good. Pat on the head, Sir! Your post heads in the direction of how my own sense of science has been emerging. It has been regularly reiterated by swansont over the years that physics is about behaviour, so we need to get rid of these 'thingies'.

Nothing can come from nothing so something always existed!
My undersrtanding is that if a particle is subquantum, it's 'nothing' in the sense that it can't interact with quantm-level particles of the Standard Model. They are nothing because, ordinarily, their behaviour has no quantum level consequences.

Slaves out of Africa...
Externet. You may find this BBC article of use - It's about somebody's Nigerian great grandfather who dealt in slaves with white slave traders: https://www.bbc.co.uk/news/world-africa-53444752 CharonY is correct in that this subject is massive and complicated... you can't tell the story with one sweep of a general brush covering 3+ centuries.

Could the real size of the universe be infinite?
It was just a descriptive to differentiate from an explosion. In inflation, there is no central point of expansion.
-
Could the real size of the universe be infinite?
Someone here may have an idea of the steps leading to the initiation of inflation.
-
Could the real size of the universe be infinite?
The process is one of all-over inflation, not a leading-edge explosion.

Looks like Afghanistan is in Taliban hands...or VERY soon to be
Sorry, I read it the wrong way... the limitations of reading text.

It's easy and consequence-free to be an armchair military tactician with hindsight to work with.

Updated to latest forum software
Read some of the upgrade blurb and spam should go down.

What was that saying: 'Never ascribe to malice that which is adequately explained by incompetence"

Lets just forgive them the most audacious attack in living memory, dig three thousand graves and forget about it. I think not. Nobody knows the consequences of their "solutions" until they are carried out.

Cleaning air after residential fire
As long as one is absoluteley sure it's not smouldering in any way. I wouldn't bring spent charcoal in, just to be safe; it can produce carbon monoxide if stll glowing unseen. You probably meant that anyway, but I'm just highlighting that point for those not familiar.

If the top topples, the lower parts have no chance. When Ghani fled, that was it. It seems to be his poor timing that has caused this situation unfolding worse than it needed to. My overall feeling is that not enough Afghani's are prepared to fight with the same conviction as the Taliban, so the end result is predictable. Is the lesson that we need to totally overrun a country, like the Allies did to Germany, in order to put into effect durable, peaceful change?

Evolution of Covid Strains.
Luck and environmental selection pressure brings them into dominance, They can come from anywhere. Wherever there is a virion, a mutant can arise from its replication. They don't have to 'learn' to be resistant, derived from a series of external pressures, a perfectly resistant mutant can also just happen to be spontaneously generated... it got lucky.

Coronavirus / COVID-19 posts
You think it will be persistent and ubiquitous, like flu and other common respiratory pathogens now? Is there too strains now? What factors tell you that herd immunity is off the table?

If I can imagine it, it is possible!
They are solutions conceived to fix a problem, which they then see if the data agrees.

Can artificial UV light clean clothes ?
It wouldn't be practical for domestic laundry and it's potentially dangerous in unfamiliar hands. You do have an immune system and microbiome to keep the little critters in check. A maximal aseptic strategy is not good for your long term health.... mental or physical.

Any help appreciated.
Yes, chronic use can play hell with micro-memory, can lead to frequent distractions of thought and feeling ambivalent about things, causing indecision.

Power cabling resonance to power a small hand held motor
The forum software does not show names when one can plus or minus a post. If there was a like-only option, ala Facebook, then one would see the names. The mods felt showing the names of those who disapprove was not a good idea... IIRC
