      The author leaves a lot out. Fusion is a money pit because of mismanagement. Most of the money goes to the Tokamak......a device that no power company will buy

            Well Mr Kurzgesagt I'd rather be tripping on toxic fossil fumes than have Chernobyl all over again
            So next time don't forget to mention how toxic nuclear waste is
            Alright??...

              No, you really wouldn't. The radiation in the Chernobyl exclusion zone is 3 times less than the minimum radiation required to increase your risk of cancer.
              Radiation and toxic fumes from coal kills 4.6 million a year, painfully.
              Trust me, nuclear power is a heck lot safer and cleaner than coal.

                      What if the sun was the last life of the universe that discovered fission and it went horribly awry?
                      There are other sun's right? They're just small if I'm right.
                      If that civilization created a sun the size of their planet and because a giant sun, it would change the temperature of the other planets to the point where only our planet was able to host life. If we screw it up it could lead to life on other planets though so I guess that's the cycle of life in the universe. Born to die and bring about new life.

                                    honestly we should stop spending so fucking much on military and weapon development, so that we'd have more money for things that are actually useful, like this.

                                                                      Also, the stellarator system doesn't have a superconductive central coil, making confinement leaks much rarer. (I have to admit I prefer stallarators over tokamaks)

The main reason is incorrect scientific theory. And understandably, incorrect construction of a reactor designed to create conditions for realization of controlled thermonuclear fusion as well. Need proofs? Over the course of 70 years great scientists of all civilized countries have not been able to create a controlled thermonuclear reactor! So long as these scientists have had no result for 70 years in a row - it is a complete defeat teory. So long as these scientists have had no result for 70 years in a row - isn’t it a pseudo science? It is obvious.

Lets say you need to learn how to age what you're looking at. As for compressor, it's same as vacuum only it becomes heavier but the same size so a compressor and a vacuum, which is to say you need matter, which is a limited resource. anything, even dirt and stone... Same scenario different hope. If you say you can hold 5 tons in a grain of sand, which is by itself impossible, hopefully we won't create a black hole because it can't be heavier than earth. Its just impossible, but very practicable and dangerous. So how do you make something true? Snap your fingers? obvious answer is NO but scientists keep pushing the possible reality that things cannot form themselves from thought. Not vice versa. Thoughts can form from things this is where you draw the line, the point of no return. There was a debate long ago If we didnt have bodies were we alive? so it comes from within, breaking chunks of outside matter and growing . I have an irrational fear of running out of space.
