Smith1980 brought it up, so I thought it would be cool to see the propaganda of science going on right now.
Science Propaganda
Small Nuclear Reactors are expensive and not the right idea
Creative people are evil. We should shun them. This is from a psychology magazine
This is from a social study and questionnaire system of finding out. Polarization has created teams so strong that even associating with opposing team members is bad. No one is allowed to have an open mind.
Heart problems have been around a lot longer than expected. Ancient Egyptian mummies show this. Apparently bodies from around the world and all walks of life throughout history had them. Our heart crisis is not what we think.
Permaculture beats out agriculture
Global Warming
Saguaro cactus are collapsing from the extreme heat last year.
Coral is being removed from Florida waters by scientists
Heat warnings from last year
The UN proposes a tax on gasoline to stop global warming
Tasmania is dying due to global warming.
The global powers do not want a repeat of the America mistake. They do not want a new wave of Nouveau riche that they have to assimilate, confiscate or destroy. New land means new resources that will devalue their monopolies and cartels.
In the Age of Sail it took around a month to sail from the colonies back to Europe, two months round trip. Thus two months was the reaction time of the Empire for both communication and military force. This was slow enough and the colonies relatively poor enough at the time that the Empire didn't respond to the Revolution. This was their mistake as America had vast resources to exploit. Now there is no place on Earth that is not forty minutes from destruction, and less than twenty-four hours from other retaliation. Similarly anything within lunar orbit is less than three days from retaliation.
On the other hand, the minimum travel time to Mars with current technology is three months, with launch windows being every two years. The communication times vary from four minutes at opposition to twenty minutes at solar conjunction. The means that a rebellion starting on Mars about six to eight months after opposition will have around ten minutes to cut off communications to Earth and then there will be around a year and a half before any forces from Earth can arrive, and such forces will be arriving with absolutely no intel of what is happening on the ground. This is unacceptable to the powers that be.
Mars colonization will not occur until the transit times to and from Mars are less than a week, year around.
I can see them in their power mad controlling personalities doing this. However in their attempt to stop this new threat they seem to be creating another threat.
Humans are NOT meant to be contained and the increasing depression rates, psychosis and restlessness is evidence of this. Space travel is Humanity's release valve as no matter what, you have the opportunity to move away, you're less likely to nuke each other.
I actually think they portrayed this well in The Expanse as when wormholes to new worlds became available, the tensions between Earth and Mars stopped because people could simply leave.
