What If You Could Shrink to the Size of an Atom?

What If You Could Shrink to the Size of an Atom?



What if you could shrink yourself down to the size of 1 mm (0.04 in), about the size of a frog’s egg? Actually no, there too many creepy crawly predators, so let’s go smaller. What if you shrunk to 10 micrometers (0.0004 in), the size of an animal cell? That’s pretty cool, but I think we can go even smaller. How about 100 nanometers (0.000004 in), the size of a virus? That’s better, but we’re not in the mood to be swallowed by white blood cells. So let’s keep going. What if you shrunk to 1 angström, the size of the atom?

Veritasium Is Wrong The Energy Probably Flows Through The Wires. Quantum Field Theory Says So.

Veritasium Is Wrong The Energy Probably Flows Through The Wires. Quantum Field Theory Says So.



A couple of weeks ago Derrick Muller of the YouTube Channel #Veritasium made a video asserting that the electrical energy in a circuit does not flow through the wires but through the fields. This is true and yet also a misleading misconception. This misconception in his problem arises because it deals with a circuit loop that reaches from the Earth to the Moon and back with a one-meter gap between the wires. He also uses a definition of the light being “on” which seems to be having any minuscule amount of current flow through the bulb. Then he justifies this will completely correct classical, non-relativistic electromagnetic theory. When in reality to address the problem, he asked fully would require Quantum Field Theory (QFT) or more specifically Quantum Electro Dynamics (QED).

Windmills Are NOT Like Dams

Windmills Are NOT Like Dams



Watch the bonus material cut from this video at

The Solution to the Windmill Paradox. This video is about the tradeoff of Windmills: the fact that the more kinetic energy you extract from the wind the slower the wind goes, the less wind you have to extract energy from, etc. How much energy is the sweet spot to extract from the wind??

Let’s think about space for a minute, ok? You know that there levels to the scope of space, right? For example, we live on planet Earth, which is part of a solar system that circles around a sun, and if you go out further, you’ll have interstellar space that fills up the Milky Way Galaxy that we reside in. Go even further than that and you’ll find a multitude of galaxies that make up the known universe. There’s a lot of levels when it comes to space.
Zooming back into the galaxies level, when you think of galaxies you think of them in the singular context. Meaning that every galaxy is one thing, one large galaxy comprised of many objects, but still, one galaxy. This all changed though when it came to Hoag’s Object. Which was a literal galaxy…inside of a galaxy.
But we’re getting a little ahead of ourselves here. Rewind back to 1950, and astronomer Arthur Hoag discovered something he didn’t expect. A ring shaped galaxy deep in space. Further measurements of this galaxy noted that it was an astounding 127,000 light years across. But what set apart Hoag’s Object from all of the other galaxies in the universe is that it is part of the .1% of galaxies that are shaped like a perfect ring. Most galaxies are spiral-like in nature, including the Milky Way and the Andromeda Galaxy. But not Hoag’s Object. Not only is in ring shaped, but its center is filled with “old stars” that make it look like something much more. Which is kind of the point we’re getting to.

Alright, so let’s dive into it right away. What could have caused not one or two, but THREE galaxies to merge together in such a way that it creates this very unique effect via the Ring-Shaped Galaxy? Well, as with much science, there is a lot of speculation and theory, but no hard proof. But we’ll let you know some of the prevailing theories, ok?
The first theory surmises that what happened here was a cause of right timing and placement. There once was one galaxy. More than likely a regularly shaped one of average galaxy size (and galaxies are huge just so we’re clear). Then, one day a rogue galaxy (meaning one that doesn’t have a tether) or another galaxy that was just in the area decided to move through the space where our first galaxy resided.
Usually, when something like this happens we get a collision and cannibal effect (more on that later) where one galaxy devours the other. But in this case, because of the distance, the second galaxy just hovered there for a while, causing all sorts of chain reactions, and then flew back out into space. When it did this, the gravity from the first galaxy took some of the stars and items from the second galaxy. When it did this the “new stars” took up space in the first galaxy, but because of various galactic forces were forced away from the core. Which is where the ring came to be. And thus the core of the ringed galaxy is its own galaxy, while the ring is also a galaxy, and the third galaxy is the space in between.
You might think that this is something rather complicated, and it is, but weirder and more random things have happened in space, so there is merit to this.
However, given the laws of probability, and further research on this ring galaxy, there is some flaws to this theory. First and foremost, as far as we can tell…this galaxy has never had a collision with anything else, even a slightly one. Furthermore, the rogue or fast-moving galaxy would’ve needed to hit the right spot in order to cause the chain reaction that the theory states made the ring. Not impossible…but very improbably. I mean we’re talking a billion-to-one shot if not more. That’s not the kind of odds scientists like to bank on when trying to explain something.
Theory #2 is one we’ve alluded to before, and that’s the concept of galactic collision.

Also maybe instead of using the circuit in the video to prank, you could use it as intruder alarm, light switch based on room light, or whatever else! It is a useful circuit. Just be careful around high voltage!
