1.2 million years

[unclemac]

Now I know this isn't NA but it is a great example of what was being crafted a million plus years ago. This should help illustrate what is and is not a manufactured NA stone tool.... If these were being made this good back then, the tumbled rocks we see here from time to time should pop out as NOT artifacts even to the greenhorns.

1.2 million-year-old ‘stone-tool workshop’ uncovered in Ethiopia is oldest ever found

Almost 600 obsidian handaxes were unearthed at the site, the study said.

I read up on carbon dating. There is a lot of disagreement amongst top scientists. Many believe carbon dating can only go back (accurately) about 50000 years. Still we hear of carbon dating “proving” mountain ranges are 4.5 million years old. I guess we need to pick a side and hang on. I love science, but I really doubt some stuff they extrapolate. They have had access to chicken eggs for CENTURIES, and still argue if they are deadly, OR a super food!😊 yet they expect me to believe they can tell how much copper is in the core of Pluto, using a radio telescope. Plus, when new info is found, to contradict previous beliefs, scientists never say “we found out we were wrong”, instead “new evidence indicates…”. I’ll get off the soapbox now

Ah but what is a year in time? Is it what we think it is now or what it was 20 billion years ago. Could be not the same thing. I’m assuming carbon dating assumes time is a constant. Maybe it is for all practical purposes, but maybe not. I don’t want to side track the original discussion as it super interesting.

Wormholes that make shortcuts through space/time by distorting the fabric of space. Of course, again, theory. I have a theory that we aren’t the only life in the universe. Science disclaims the idea (for the most part) saying they need proof first. Where is the proof for multiple universes, and most of string theory? Gotta love it.

I’d love to see a picture of that

I saw 2000 arrows from a cache found in southern New Mexico in the early 1960s at the El Paso Archaeological society lab. I was a kid and didn't own a camera. These are my estimates, I did not count them someone at the lab did. 1800 had a fire hardened wood tip, 180 had a chip stuck into the fire hardened wood tip and 20 had a hafted arrowpoint.

Wonder what the age that cache was. I wonder if it was early adoption of bow and arrow or later.

600 hundred hand axes unearthed. And they show one?

 

[unclemac]

these news media reports are always like that. If you want the real rundown you have to go find the professional writeups the info comes from, those can be hard to find and are usually very, very long and filled with data that is very confusing to the general public.

Mimbres I would guess so around 1000 ad, could be Mogollon and go into the 1300s.

Most every astrophysicist and cosmologist I've heard/seen/read are
certain there is life elsewhere in the universe. Still, it is only theory until
proven fact; that is the very nature of science.

As for space/time, time is not a constant due to time dilation. The
GPS satellites circling the Earth must adjust their atomic clocks to
account for the lower gravity and their speed relative to the Earth.
If they did not make that time adjustment, people following their
GPS would wind up in St. Charles instead of St. Louis.

Here's a great article that explains it in (somewhat) plainer terms.

HOW RELATIVISTIC TIME DILATION AND GPS ARE RELATED

Einstein's theory of relativity is one of the most significant achievements in the history of science. All the more so as it has been developed by only one person. Many of the conclusions drawn from this theory are literally striking and seem completely unbelievable at first glance. One of the...

I can't prove it, but like you I most definitely believe there is life
elsewhere in the universe. I'd be thrilled even if all they found were
tadpoles, as given enough time and Mr. Darwin's theory, intelligent,
sentient life will evolve. We could also, just as easily, meet a species
that is a billion years ahead of us in development, and who aren't
the least bit interested in conversing with such a primitive culture.
