I read somewhere that even totally annihilating a gram of matter/antimatter only gives enough energy to accelerate a gram of matter to 50% light speed, assuming perfectly using the energy. How to harness the gamma rays is unknown.
Basically current physics says getting to relativistic speeds is close to impossible.

You can't reach the speed of light, just get closer and closer. Takes about a year at 1G to really get the relativistic effects at close to light speed.
Problem is everything you hit, even light, has so much energy that survival would be, lets say hard. The energy requirements make it impossible according to current physics.

Actually about 7.2 years ship time and just over 42 years Earth time, quicker if you don't want to stop at the end. Takes about a year at 1G to get close to light speed and really take advantage of relativistic time compression.
Of course the energy requirements would be huge and current physics says it is close to impossible.

Alberta does like to be different. The rules in BC are more like the UK.

Compared to those who need labour for their farm and their retirement plan and those kids having an unknown survival rate.

By fall, do you mean leaves dropping off the heat stressed trees early like is happening here on the west coast of Canada? As for the axial tilt and various other changes in the orbit of the Earth, yes it drives climate change on a few thousand-100,000 year time scale, not a couple of hundred years. Your also correct that global dimming caused by smog and sulpher dioxide did cause cooling as well as a lot of other problems.

Yep, much better to cut a 100 ft wide, 100's of mile long strip through the forest for an oil pipeline. Then another for a leaky gas pipeline.

Yes, eventually life will adapt, though there is always a lag. This time the climate is changing so fast that the lag may be too long.

Have to remember that in those days there was basically no law enforcement so being armed was more important. Even the British Bill of Rights of 1689 included arms rights for self defence. It was also considered bad to have a standing army as it led to tyranny, like soldiers enforcing the law and worse. Why militias were considered important. At that going back a few centuries more, being proficient with arms as well as owning some was considered a requirement for freemen. No standing army, rather militias then.

Wealth inequality is a big cause of the problems in the west. Same thing happened in the '30's. People, especially the young, are stressed out by their finances and simple populists with their simple solutions sound good. Immigrants are taking your jobs makes the problem simple and easy to fix by getting rid of immigrants. Throw in some culture war and unrealistic promises and win elections, if not this time, then next time as things aren't improving under the mainstream. The wealthy have so much power that the obvious solutions will not be implemented so our society is likely to die like many previous ones when the wealth disparity grew to much. Throw in climate change, the leading cause of civilization crashes and I don't see much hope.

Or, over a beer, they'll agree to split the market and keep prices and profits high. Though sometimes they will lower prices to put the new competition out of business, before raising them again. The higher the barrier to entry, the more likely that happens.

All comes down to a Supreme Court that has Justices who believe in a strong President rather then the law. From the outside, the Supreme Court seems to be making some weird decisions not based on the Constitution or other law.

Tell him he's an idiot to his face and he'll remember you for a long time. Tell him he's wonderful and he might remember you next week. The man's got mental problems to say the least.

The media (NBC?) really pushed the idea to sell The Apprentice. Seen an interview with the guy who did a lot of it, full of regret.

Yep, now expensive, disposable and unreliable crap.
We live in a world of enshittification and it is not profitable to make good stuff, how do you do repeat sales. Besides the tariffs will remove the competition which is good for profits.
