    The problem is that nuclear reactors can’t be built fast. We’ve also lost a lot of the expertise to age and retirement.

    Nuclear should have been a major factor in dealing with climate change. Unfortunately, we no longer have time for it to take up the slack. It will need to catch up with other renewable energy sources, we can’t wait for it.



  • I think it’s more the fact that the Russians likely wouldn’t be selling their “good” nukes. They would be selling the old, run-down ones. They would be a large chance they wouldn’t detonate properly.

    There’s also a lot of debate on how well the rest of Russia’s nuclear arsenal has been maintained. It’s highly specialist work that can’t easily be verified by non-specialists. I wouldn’t be surprised if a lot of Russian nukes were already non-viable due to corruption affecting maintenance.





  • I personally support this plan. Smoking in the UK has already plummeted. A lot of smokers have moved to vaping. Unfortunately, those left are often the ruder ones. Limiting where they cam smoke, or reduce expire for everyone else is a big dead for me.

    Additionally, it’s not banning nicotine, it’s banning cigarettes. Vapes have changes the balance on that one. They are less damaging, and cause far less issues with passive smoking. This acts as a pressure relief valve, rather than a blanket nicotine ban. Also, at no point will an existing (legal) smoker go from legal to illegal.

    The vape issue definitely needs fixing. A number have found advertising to younger users is a good money maker. Limiting the options here l, without an outright ban would help reduce the harm to children. It wouldn’t significantly affect ex smokers who moved to vaping.














  • Spacetime (you can’t talk about time only) or at least its substrate does get in knots, best we can tell. We call them fundimental particles. String theory/membrane theory are still very much theoretical physics right now, however, so it could be completely wrong.

    The other alternative is a closed timelike curve. According to relativity, there are valid solutions that create such a curve. Theoretically, you could fly into one, traverse it, and exit before you entered at the start. This does require several black holes, moving at stupid speeds, orbiting each other, however. It’s also theoretical. While the equations allow it, we know they are incomplete. Physics seems to have blocks on anything that can mess with causality. It’s likely something, currently unknown, kicks in to stop the closed timelike curve from forming.


  • A plastic bag tax came into for in the UK a few years back. The fee was minimal, but it was still remarkably effective. It’s not the amount, its the fact you have to pay at all. Most people have transitioned to using reusable bags. It’s made a significant dent in plastic bag waste.
