I was watching a documentary on the emergence of insects from the sea, and times of the dinosaurs, when the atmosphere held a volume of 30% Oxygen. Why has it reduced to 20%, where did it all go?

I think I like Bob Hawke's 1980s Medicare system. It is still going, voters love it.Communism provided public services and public ownership of basic industry.Communism was well known for providing top notch healthcare to all citizens, something that the west is incapable of.
Under communism there was no parliamentary opposition. Nowadays,the leader of the opposition gets poisoned and imprisoned.I'd say communism, as an evil work to start with demoralized Russians. So many of their own citizen were killed. Russia, the sleeping bear awoke with problems. The system reverted sometimes to capitalism, resulting in too powerful rich business men emerging, who were killed.
Communism provided public services and public ownership of basic industry. Privatisation resulted in a few crooks making huge profits through a bent tendering process and increasing the prices of fuel and food. The government is planning to reduce its healthcare budget. The employment rate has not changed significantly.
So do you approve of the state of modern Russia? In what ways is it preferable to the communist state that preceded it?I think it would end up like the reunification of Germany.
Which side should compromise to reunify Korea? What did we learn from Vietnam?
Putin is just a new dictator, he managed to destabilize the once democratic system. I think the reunification of North and South Korea would end up well.No, Gorbachev ended the regime, and at first at least, it was okay.That was 30 years ago. Do you approve of what has replaced it?
These are some good examples. They can be judged badly in retrospect, but accomplished important things in their day. Newton was changed and helped the abolition cause later in life. A help behind Wilberforce.Quote from: Europan OceanIs there an example on your mind of one such?I was thinking of James Cook, the British explorer, who explored the east coast of Australia, around 1770.
- His statue in Sydney has been graffitied multiple times, accusing him of crimes against the aboriginal population
- There are suggestion that his statue in another location be removed
- But I don't think he committed any crimes against the aboriginal population - all he did was to describe the country to a population who didn't know about it
- This is unlike later settlers who certainly displaced the native population (often violently), and smallpox and other European disease had a devastating impact on the native population.
A better-known example is Abraham Lincoln, who (I have heard) is accused of keeping slaves when he was young.
- I did a quick search, and found that to be unlikely, so I didn't mention it.
Perhaps a more dramatic example is John Newton, who was an active participant in the slave trade, but later realized that it was evil.
For many of us today, we have our clothes made in near-slavery conditions, but out of sight, in other nations. How will history view us?
No, Gorbachev ended the regime, and at first at least, it was okay.I don't want to hurt communists, although adversaries like North Korean communists, I hope they topple, like Russia did.So you want someone else to hurt them, and you approve of the current Russian regime?
Sounds like more hate speech.I in my mind I hate communism, the mandates, the loss of free thought and enterprise, religion and the right treatment of human and animal life. I hate abortion and infanticide, I don't like the idea of people ending their own lives, at least they have a say in it.
I think that indiscriminate canceling is a bad thing.Is there an example on your mind of one such?
There are people who we would consider enlightened by the standards of their day, but who also did some things that we might disagree with today. Do we cancel the whole person, forgetting that they actually contributed to progress (as we measure it today)?
This often comes out in the context of those who owned slaves, at a time when most rich people owned slaves. Perhaps we should look at how they treated their slaves, rather than the fact that they owned slaves.
- Or in those who wanted to abolish slavery, but who had, at some point in their life had owned slaves.
What about people in the arts, who we now discover did things which we don't approve?
Rather than tear down their statue, do we put a an extra plaque on their plinth, saying that "In 2022, we find good evidence that this person did X, Y & Z. This was made illegal by the ABC bill of 2015..."?
My hate speech? I don't understand. Are you saying you are communist?Only hate speech should be censored, not cancelled, cancelling is a new dictator style idea. Free speech is the rule, the right. Science should be civilly debated.That in itself is hate speech, leveled against those you disagree with. Please censor yourself.
From outside the atmosphere, would the young cooler Sun be yellow like it is today, or dimmer, red or orange?From that time, millions of years as you say after the impact when the moon was still hot, if you could see the Sun, even from above the atmosphere, would it have looked cooler than today's view, maybe it was orange or red? Not bright yellow?The debris would have cooled quickly. The moons, as they grew, might have generated their own heat. There were at least two main moons for a while which eventually collided at very slow speed, thus forming the current moon and defining the month.
If all the debris blocked the sun, I can't imagine that lasting for too long as most of the parts either combined or collided with Earth. Most of what would exit the system probably did so quickly in a day or so.
Any discoloration of the sun would probably be due to dust in the atmosphere. Plenty of metors coming in to constantly replace that, but I don't think there would have been much atmosphere left after the impact, so I can't see the dust being suspended for long. Still, Mars with its thin atmosphere mananges to hold onto enough stuff to color everything, so maybe it looked a bit like a sunset, which turns red because I think red light penetrates the thick (thousands of km) atmosphere better than the higher frequencies, just like red light reaches us from the center of the galaxy when the visible wavelengths all find something to hit.
