The argument goes like this: If we can assume that technology will eventually reach a point where we can create a perfectly lifelike simulation of reality, then we can create people who think they're alive. If we allow those virtual people to go their own way and advance, then they will eventually create their own simulations, and those people will create their own simulations in turn, etc. Assuming that these simulations are indistinguishable from reality, then the odds that we're living in the one really real reality are, according to Musk, "one in billions." Tyson agrees; it's a simple matter of statistics and probability!

Neil Degrasse Tyson Numbers may not lie, but they certainly are assholes sometimes.

Why You Shouldn't Have Asked Them:

The theory itself isn't necessarily stupid, but what neither Musk nor Tyson seem to realize is that it's actually philosophy, not science. Tyson in particular is famously disdainful of that stuff, so maybe it's no surprise he doesn't like the descriptor. But ask either a scientist or a philosopher about this theory, and they will come to a rare agreement: Musk and Tyson are full of s**t.

Neil deGrasse Tyson Try different Spock quote, dude: "Highly illogical."

Popular Science asked theoretical physicist Brian Greene what he thought about it, and Greene responded that there's no evidence. If we were to experience some kind of reality-altering glitch, like those frequently seen in the Matrix movies, then there might be a case to make, but we've seen none of that. On the navel-gazing side, Vice asked a couple of philosophers, who concluded that the premise itself is nonsense. A simulation that is indistinguishable from reality is reality, or else you could, you know, distinguish it. There's literally no difference between living in reality and living in a 100-percent perfect reproduction of reality, so why bother with it?

Any way you classify the theory -- philosophically or scientifically -- it all boils down to the same thing: stoner-grade mental masturbation.

Why You Shouldn't Have Asked Them:

Bill Nye isn't the Master of All Sciences. That's not a thing. He has an undergraduate degree in mechanical engineering from Cornell University, and worked for Boeing for a while before trying to break into the comedy industry. That's when Ross Schafer talked him into the idea of combining comedy with science education. Of course, Bill Nye: An Engineering Guy Who Fills A Pop Culture Niche isn't as catchy a title for children's television.

Now, we love Bill Nye as much as anyone, and on the topic of climate change, he's absolutely right. The problem comes when the media cites him as an authority. Nye is charismatic and lovable and a whole bunch of Millennial nerds had posters of him in their rooms, but it really would be better to feature boring old real climate scientists, like Michael Mann or James Hansen.

NASA "Would it help if I started calling myself 'The Science Mann'?"

"Who the hell are they?"

Exactly.

Trying to teach the world about the threat of climate change is cool and all, but it can backfire if you're not actually an expert in that field. In 2013, MSNBC conducted an interview with Nye to explain that year's catastrophic New England blizzard. But Nye's amateur explanation of the mechanics of blizzards and hurricanes caught the eye of Jason Samenow, The Washington Post's weather editor, who holds a master's degree in atmospheric science. He wrote a devastating takedown of Nye's interview, which was a mixture of inaccurate information and stuff that Nye may as well have picked up from Twister.

MSNBC And maybe a little bit of The Day After Tomorrow.

And that's basically handing the ball to the other team -- "See? This guy is wrong about one thing, so he must be wrong about everything!" There's no question Nye is smarter than us, and more than entitled to his opinion on the issue -- especially since, again, it's correct in the larger sense. But we love space rockets. We think space rockets are cool. We are passionate about space rockets and believe they are an important issue. You should not invite us on your TV show to explain space rockets.

Why You Shouldn't Have Asked Them:

On the topic of earthquakes, Michio Kaku knows about as much as you do. And when we say that, we are correctly assuming that you don't know s**t. Ask a real earthquake expert, and they'll be happy to tell you that America has very little risk of experiencing the kind of apocalyptic doomsday quake that Kaku was all too excited to warn us about. But Kaku has crazy hair like a movie scientist, and that looks great on camera.

David Becker/Stringer/Getty Images Call us old-fashioned, but we like our scientists to seem a bit unhinged.

The teleportation thing is a whole bunch of nonsense, too. Scientists were just teleporting the information from one photon to another, and it has almost nothing to do with teleporting entire people or objects. According to at least one NASA scientist, "Nothing in the physics of today gives a hint about how that might be possible."

In another video, Kaku talks about creating a "library of souls" -- one you could walk into and sit down for a chat with a hologram of Winston Churchill or Albert Einstein, since it'd have all their respective memories.

DePauw University "I took the name from a Magic: The Gathering card."

In another, he discusses the depictions of traveling between dimensions in the Fantastic Four movie, and says that it isn't unrealistic at all. Here he calls Pluto a comet, and predicts we will land on Mars mid-century. In this interview with MSNBC, Kaku theorizes that maybe the reason aliens haven't visited us is that they blew themselves up with nukes. They ... covered that in physics class?

In conclusion: Newscasters, just because Kaku is a physicist and you don't understand what that means, that doesn't mean you should cut to him for elaborate takes on alien theory just in case that's what physics is about.

But that doesn't mean that he knows everything. He's not a My Little Pony expert, for example, and you wouldn't cut to him for expert opinions on Sparkledew's fuckability or whatever. And yet in recent years, the media has cited Hawking as an authority on a number of increasingly absurd apocalyptic predictions. In 2010, they freaked out when Hawking warned that aliens might learn of our existence and respond by wiping us out, Independence Day-style. Then in 2016, he warned that robots might become self-aware within the next 100 years and wipe us out, Terminator-style. Then he said an asteroid collision is imminent, which would kill us all, Armageddon-style. Most recently, since Brexit, he's started warning us that we only have 1,000 years left as a species, unless we double down on interstellar colonization, because politics are going to kill us all. Which one was that, Hunger Games?

Bryan Bedder/Stringer/Getty Images "And if you read the calculations, you'll see undeniable proof that Team Gale is the only correct choice."

Why You Shouldn't Have Asked Them:

It makes sense to listen to what Hawking says when he's talking about universal inflation, or quantum gravity, or black hole radiation, or anything else we don't have a distant hope of understanding. But Hawking isn't any more of an authority on aliens, or robots, or asteroids, or goddamn politics than you are. There's a reason his field is called "theoretical physics" and not "practical doomsday prognostication."

If you're after realistic predictions about the chances of alien invasion, robot uprisings, or Mad Max apocalyptic social decay, then you're s**t out of luck -- there are no experts on that. And if there are, this stupid comedy website is probably one of them. Here's our expert prediction: Life is always going to be weird and scary, and you'll worry about space and robots and water wars, but fantastical sci-fi scenarios are not going to kill you.

Cancer is.

Behind every awful movie is the idea for a good one. Old man Indiana Jones discovers aliens. Good in theory, bad in practice. Batman fights Superman. So simple, but so bad. Are there good translations of these movies hidden within the stinking turds that saw the light of day? Jack O'Brien hosts Soren Bowie, Daniel O'Brien and Katie Willert of 'After Hours' on our next live podcast to find an answer as they discuss their ideal versions of flops, reboots, and remakes.
