Physicist Breaks Down The Science Of 11 DC Superhero Scenes | How Real Is It? | Insider

Jim Kakalios takes a closer look at the physics of the DC universe. Here, he reacts to 11 memorable scenes from DC movies and rates them based on their accuracy.
Kakalios addresses physical feats of DC superheroes, such as Joker in "Suicide Squad" jumping from an extreme height into a shallow vat of acid and Harley Quinn in "Birds of Prey" skating behind an automobile at high speed. He looks at the realism of superheroes' incredible skills, such as Aquaman's ability to sonically communicate with sharks and other fish. Would Shazam be able to charge up a mobile phone by shooting bolts of lightning at it? What material would Wonder Woman's bracelets need to be in order to deflect bullets?
Superman and Batman come under scrutiny in the video. Kakalios looks at Bruce Wayne's cape's rigidity in "Batman Begins" and whether it would allow Batman to fly across Gotham City. Would Superman be able to turn back time by flying around the world? Why can't he see through lead in "Man of Steel"? And finally, what are the odds that both Batman and Superman have mothers named Martha? Kakalios calculates the odds from "Batman v Superman: Dawn of Justice."
Kakalios is the author of three books, "The Physics of Superheroes," "The Physics of Everyday Things," and "The Amazing Story of Quantum Mechanics." He also worked as a science consultant for the Warner Bros. film "Watchmen" and won a regional Emmy for the video "Science of Watchmen." A physics professor at the University of Minnesota, Kakalios teaches a popular class that uses comic books to illustrate the principles of physics.

I always wonder about super speed. The ability to run at X amounts of speed doesn't just mean your body can go that fast but it also means your brain has to be developed enough to process the environment. Due to that, every speedster should/could basically be looking at the world as if everything was moving at a snails pace because their brains are processing things at "1,000" times faster than the normal brain and at the same time they should also be mega geniuses.

[@auburn1357]

Yay physics! Thank you for breaking these down so well and giving excellent insight. Though I wanted to discuss the Martha controversy further. To be fair, we live in our universe and not the one where Metropolis and Gotham are cities so it might be that in that world there are still a lot more women named Martha. Okay but seriously, the probability of both their parents having the name Martha is low but it does not matter what their mother's name is. The main probability we are interested in is what is the probability of two men having mothers with the same name. This is because if Clark had said "Save Windy" and both their mothers were named Windy then the effect on the plot would be the same. This is akin to the statistics professors make up exam. Two students say they were not able to come in for an exam because they had a blown tire but really they needed extra time. When they come in to take the make up exam, the professor tests them individually and has only one question on the exam: what tire blew out? It has always been canon that Bruce's mom was named Martha and Clark's mom has been named Martha since the 1950s. You calculated the probability of different comic book writers randomly writing two characters who had mothers with the same name. Though things this random appear to happen. I don't think they purposefully made these characters have mothers with the same name so that a move over half a century later can make it a plot point.

No one: Me: Hold on a second, why doesn't x-ray vision get a higher score...Clark can in fact generate light from his own eyes, which seems to be the requirement for the x-ray capabilities...in conclusion he's just toning down the distructive capacity of his heat/laser vision to gain x-ray capabilities... isn't that a miracle exemption🧑‍💻... I recommend an upgrade to 8/10. Me: 👀 it was in that moment I knew I became too involved in this video 😂

[@doctaflo]

He should’ve lost MORE points: How are the x-rays getting back to his eyes? when you get an x-ray, there’s an emitter on one side of you and a photographic plate or computer sensor on the other side to receive the radiation and form the image. maybe some tiny fraction of x-rays deflected by electrons would bounce 180 degrees back, but then the total dose of radiation would surely be lethal.

[@HeroicHorizon]

@@doctaflo Hahaha good one

[@Ixidor85]

A couple of points I would make. 1st: Flash uses the speedforce to accelerate time, that would speed up neurotransmision too so it wouldn't be a problem. In the comics it even states that he can think faster do to the speedforce effect. 2nd: Flash was running along a curved wall, that would change his vector creating a centrifugal force and giving him his own "weight". No need for gravity to give his feet grip in this particular wall run. 3rd: if Clark's eyes were the source of the X-rays they would go through the things he is looking at and wouldn't be able to receive them. There should be another source for these X-rays so Supes can look at them. Loved the video though. 😛

[@josephloughrey9529]

His commenting and breakdowns are the best ever 10/10 but his grading pattern is a bit all over the place :D Great video, Great guy!

[@ManveerMattu]

I love Superman

[@zubaid-.-2846]

Breaking down the Flash in the Snyder Cut of Justice League would be glorious.

[@zwd7898]

About the energy thing for the flash and needing to eat. In several comics the flash always had to eat. And kid flash even had a compartment in his chest that area where he kept special made energy bars for that purpose.

[@FirstNameLastName-tg3rc]

20:47 If I was that dude, I'd be pissed.

[@cougarkids4978]

I’m happy they had this guy again. He’s really funny and he actually likes the movies.

[@TheMoises1213]

Love this!!! He’s so ecstatic talking about it and he knows what he’s talking about yess!

[@miklu26]

This is so cool! More please

[@tyronelau4200]

I should be asleep but this is interesting

[@izzojoseph2]

This dude makes me want to study physics

[@sebastianperalta5139]

Great video. This guy is amazing

[@melontusk7358]

I love how improbable the Martha scene was, which means it makes a lot of sense for Batfleck to freak out (the dude also has PTSD). And by the way, could you ask Professor Jim to do an episode breaking down the DC Multiverse? With String theory and multidimensional branes and how Darkseid came from a different world than ours? Or how Superman flies in "Man of Steel" (by manipulating gravitational fields with gravitons, which is why snow particles were levitating around him?There is so much potential for a video. I've always adored his work on "Watchmen".

[@yifanzheng1999]

I remember reading the Physics of Superheroes when I was younger, it was great

[@sldho66man]

Now i’m no scientist, so can someone explain to me why the shouldn’t be able to run vertically? Isn’t the centrifugal force supposed to give him more weight, so he actually has weight to push down on the wall?

[@darkdraagoon]

Cause to stick to a surface you need to have force that push you into that surface. So if Flash run first and he use the force to run, he will push himself away from the wall and there is no force to push him back into the wall to keep running like that. Example would be you get a string and attach something to one end, spin it around but then let go. The object will fly away from you. The flash will be in reverse which he will fly to the centre instead of sticking to the wall.

[@SennaAugustus]

You can try it yourself. Go into a swimming pool, and kick out against the wall. You'll need some effort to get back to the wall again.

[@hurrdurr9193]

This guy is my new favorite person ever, I could listen to him explain superhero shit all day

[@RealCrazyDiamond]

This guy is legit a super hero himself. I would love to see a movie about him fighting evildoers with science.

[@CarlosCardoso2amissao]

"The Flash can't run on a wall". Dude it's The oldest trick. Have you ever seen a death globe?

[@puneetha7167]

He said flash cannot run on flat vertical surfaces. The death globe stunt u r talking about has a curved wall on which the cars and bikes speed on(I hope that is the trick u r talking about)

[@MaegnasMw]

His estimate for the speed in the first segment (falling from a large height to a shallow pool) is WAY off at 44m/s. If you fall from 5m gravity accelerates you to 10m/s (that's 36km/h or 22.5mph). if you fall from 20m, gravity takes you to 20m/s (72km/h or 45mph). In his example, falling from 11m gave 44m/s??? In what universe?? :P

[@garywang4359]

Listening to this dude explain the sport of creating the world record belly flops, all I can think about is Superman and Cyborg's conversation about would you rather live or just die.

[@BuyoganExtendedStories]

I like this guy. He explained physics so simple that I can understand

[@Boogie3D]

A physicist who mixes imperial and metric units all the time...

[@ethanwilliams7706]

America being complicated for no reason at its finest

[@Peter_Cordes]

Only because he's trying to accommodate a general audience that includes the US, where he lives. If he was just talking about this for fun with other physicists over coffee, they'd likely be mostly metric. (Although again, they'd be in the US and have that unfortunate influence on their choice of units for casual usage.) I was pleasantly surprised how little US units were used in this.

[@kevinhedman2314]

I love how you always know these are legit physicists by how nerdy they look. Glad to know I’m getting good info.

[@TeamOT]

Holy shiet, the Martha thing was the biggest burn in this entire video.

[@MohamedShawky]

We need more of this guy :d

[@Shazistic]

Random fact Abraham Lincoln was the only president ever to have a patent. -The Shades 💛💛

[@mslightsite]

ok, cool

[@victorvalverde3895]

Cool cool cool
