YouTube Comments on Mirror Inspecting

Before that, I was a human cannonball. Then I was fired.

Basically think Platform 9 3/4 from Harry Potter.

Just this one is way smaller and it’s the first time it’s been done.

I’m going to summarize it here: A small gap in a wall is made. Then conductors are placed on either side of the opening and electrons are bounced back and forth between the conductors. There are so many electrons bouncing back and forth that radio waves cannot pass this barrier and therefore bounce back.

Basically, it tricks the radio waves into thinking there’s a solid barrier there when it’s really just a ton of moving electrons.

If they scale this experiment up a bit, then photons (light) would also bounce off these electron barriers and it would appear that the wall was solid.

Lemme add a few things that I thought of: If they do this, all light that hits the electron barrier will bounce back. It’ll basically be a mirror of electrons. So you’d probably see yourself and you could walk through it.

I’m not actually sure you could walk through a wall of electrons, but you COULD just turn it off and walk through.

But if you’re just turning it off to walk through and it shows you a reflection of yourself, shouldn’t you have just used a mirror that can roll back and forth?

Holy crap. If this is just mirrors like they seem to be implying…Why haven’t we used this yet? Like, for everything.

Also, if it’s adjustable that would be way useful.
