Can I ask a question about ... our Universe?

Dave, would you please make more videos on fundamentals? I need more essentials on electronics.

Of all the videos, what info in particular are you lacking?

m k:
What are scales of basic forces?
Leave nucleus and dark matter out.
So EM, gravitation and dark energy.

--- Quote ---Of some 100 known amino acids, only 20 are used in proteins, and all are left-handed ones. When scientists make amino acids in laboratories, in imitation of what they feel possibly occurred in a prebiotic soup, they find an equal number of right-handed and left-handed molecules. “This kind of 50-50 distribution,” reports The New York Times, is “not characteristic of life, which depends on left-handed amino acids alone.” Why living organisms are made up of only left-handed amino acids is “a great mystery.” Even amino acids found in meteorites “showed excesses of left-handed forms.”

Found this one: https://newatlas.com/amino-acids-primordial-soup-stack-themselves/60873/

It is from 2019, and as with everything on the net the question is if it is true, but interesting nonetheless.

But even when the recipe to make a rudimentary life form is discovered it still does not answer the why question. And a new question can be asked, where did the amino acids come from in the first place. Since found in meteorites they seem to be spread across the universe, which means that under the right conditions there can be life in whatever form on other planets, even nearby ones.

Single cell organisms can thrive in very harsh conditions, based on findings on our own planet.

But discovery of such is a difficult and time consuming process. Just look at the voyager probes. Takes years to fly out and gather information. And that is just within our own solar system.

For example, I was told I'm not supposed to place my crystals by the edge of my PCB. They should be at least 1 cm away from edges. But I looked at my PCB again, only to find there ain't enough space to place my crystals far away enough from the edge. So what should I do?

why are there 8 planets in our solar system? why not 10, 25, 6?

where were things before the big bang? where are we going? and why are we going?

the universe is dark dark dark. Isn't that soooo scary?

If God created us, where did he get the time to create soooooo many things and sooooooo many creatures? He even created cats and tigers to differentiate themselves....

and most importantly, we humans' lives are very hard in this universe. What's the point/purpose of lives?

Why do you think what we are perceiving consists of real things at all? All these questions you ask are just the decisions that the entity or entities that started this simulation decided to put in. The simulation only presents things to the degree that it takes to make you think you are living in a real world. You think there are lots of stars out there? It only seems that way because that's what the simulation presents to your brain. Pick a star to fly to - it will be presented to you as needed and will even look like you got to one eventually. But it never needed to be simulated as a full star unless it needed to be.

Same goes for all your other questions.
