Time travel to the past is absolutely possible, but you risk going insane if your past self is involved at all.

It's not a vaccine. In 2017, there was an article published stating that someone had developed an implantable RFID chip one fifth the width of a human hair (small enough to fit in a syringe). It works at 60 GHz, one of the 5G frequencies. Why do you think the micro towers have been going up at...

:censored:

It's a magical device invented by unicorns for taking over the world.

I play retro videogames sometimes, and I came across a Nintendo 64 game called Body Harvest which was published in 1998. It's about using time travel to stop the end of the world, and it's eerily similar to reality. Here's part of the intro: On the first level, there's a town called...

I think you misread my post. I was referring to the electric field in the equation for energy density. I did make at least one mistake, though. The equation for total energy should have contained a volume integral instead of assuming the energy density is everywhere the same. I was hoping...

That's it, I'm never eating again. I'm switching to solar power. :sick:

There is absolutely no reason for so-called fossil fuels to run out. You see, in addition to being pumped out of the ground, they can be produced synthetically using something called "gas to liquids" technology. One of these technologies is the Fischer-Tropsch process, and it was invented in the...

Try it at work instead. :D Joking aside, it reminds me a little bit about the story of Tesla getting a high voltage shock from one of his machines. He said he was able to see the immediate past & future but was unable to move. Fortunately, his assistant was there to save his life.

I admit I didn't explain it well, as I was in kind of a hurry. If you look at the Wikipedia article on "electric field" & read the section titled "Energy in the electric field", you will find that there is a well-defined energy density in an electromagnetic field equal to: u = 0.5 * epsilon *...

It has been known for a long time that such fields have mass. I believe it was derived from Maxwell's equations in the late 19th century. A more detailed explanation can be found in the Feynman lectures on physics, volume 2, chapter 28, titled "Electromagnetic mass", and elsewhere online. I'd...
