30 million years ago, in a distant galaxy, 30 million light years away, two black holes collided. Each black hole is itself a significant disturbance in the fabric of space and time. When they collide, it creates an even greater ripple that gets sent out at the speed of light.

A ripple through the fabric of space and time. In the world of technology, a person is born called Albert Einstein, who thinks about the fabric of space and time. He comes up with the general theory of relativity, predicting the fact that such a thing as ripples through the fabric of space and time exists. We would later show that two black holes would be the best example of a ripple through the fabric of space and time.

Meanwhile, this ripple continues to move. Einstein predicts we should be able to detect one of these. We don't have the technology yet; that would take another 80 to 90 years just to create the apparatus that could detect it. We build the apparatus.

This holds a laser interferometric gravity wave Observatory, LIGO for short. We turn on the switch. Within days of turning on the switch, that wave washes across the Earth, and we detect it. We detected something that was cast into motion before we were human.

Einstein not only predicted the existence of gravity waves; he came up with the general theory of relativity. He also laid the foundation for the invention of the laser, and it is lasers that were used to detect the gravity waves. That's badass!

That's [Music] Einstein.

Later stages of the Civil War part 2

All right, so we’ve been talking about the later stages of the Civil War. In the last video, we just did a brief overview of the end of 1863, after the North has won the Battle of Gettysburg and Lee has been turned around and sent back down to Richmond, w…

STOP SAVING MONEY | The Dollar Crisis Just Got Worse

What’s big guys? It’s Graham here. So, apparently, a lot can change, and quickly. Because in April of 2020, CBC posted a video titled “Why is the US dollar so powerful?” only to post a follow-up two years later with a new headline, “Why the US dollar may …

Net exports and capital outflows

Let’s take a look at our GDP equation for an open economy. So, GDP is equal to national income, and that’s going to be equal to consumption plus investment plus government spending. And since this is an open economy, plus net exports. Now, the first thi…

Directional derivative

Hello everyone. So here, I’m going to talk about the directional derivative. That’s a way to extend the idea of a partial derivative. Partial derivatives, if you’ll remember, have to do with functions with some kind of multivariable input. I’ll just use t…
