Curiosity about E=mc squared

How does science work? And what's all this about quantum mechanics?

People are working on fusion energy. Once they figure it out, if they ever do, it will solve our energy problems for good. The bad news is that it's very difficult to get working.

Note that this isn't the mythical cold fusion. This is hot fusion. Very hot. Here's a Chinese experimental fusion reactor that ran at 100 million degrees C for 101 seconds.

And here's the ITER project, a Western experimental project.

Someday we'll have this. A few decades away probably.

Maybe, maybe not. Some solutions are more expensive than the result they give.
One thing is for sure it will not solve all our energy problems for good, until we learn to use less.

I believe that the universe (past) is growing / condensing at speed c (speed of light) towards the future. That's why nothing can go faster than light. There is nowhere to go yet. So I consider mc^2 to be something like the kinetic energy of matter "coming" from the future. Why twice? I don't know, maybe suitable antimatter is also neended…
