Professor Dave ExplainsThe double-slit experiment is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when you send electrons through there? Or just one electron? It's crazy stuff! Check it out.

But the surprising part is the conspiracy theories that have arisen, implying that the government deliberately manufactured and deployed them. This is totally idiotic on so many levels, the primary level being purely scientific, so let's dig into it and learn somethings about hurricanes and weather in general.

You have Bret, a fake biologist who tells everyone he deserves a Nobel prize for no reason, and really just spreads misinformation about biomedical topics on the internet which get people killed. Then you have Eric, a fake physicist who tells everyone he deserves a Nobel prize for no reason, and really just spreads anti-establishment tripe all over the internet that degrades public perception of academia and the scientific community. Basically, these guys are gigantic assholes. But they've managed to convince so many people that they're brilliant renegades who have been shunned by the establishment, because their truth is just too hot to handle. How are they able to do this, and can their fans be shown what massive frauds they really are? Let's take a crack at it!

The vast majority of creationists are completely clueless when it comes to these topics, so learning the basics will enable you to run circles around them. Even intelligent design proponents sound their absolute dumbest when presenting fallacious arguments surrounding genetics. Let's go over the ridiculous things they say so that you will know precisely how to respond.

Now let's check out some things they say regarding abiogenesis, or the origin of life on Earth from non-living matter. This is absolutely inconceivable to any creationist, who insists that life was made nice and special by their deity, whether in its current form or as something more primitive which then evolved to some degree. They do not understand the science behind the origin of life, the research that has been going on in this field for 75 years, and their talking points illustrate this immaculately. Let's clarify a few things together!

But in the early 1900s, the field of metaethics was born, which was a novel manner to identify how we can discuss ethical subjects in general. What was metaethics all about, and what innovations did it bring? Let's find out!
