I think Homelander has the most cool looking heat vision mainly because the actor is so good at making it look like he's shooting lasers from his eyes

Based on the power Superman is able to release with his heat vision, it stands to reason that he can vary the intensity of it. If he let off his full strength every time he shot a laser out of his eyes, he'd be causing mass damage to everything near his target

My personal explanation has always been that A: his bioelectric aura which covers him and his suit (canon) is what absorbs sunlight, not just through his skin (since most of his skin is covered by suit), and B, his cells aren't just solar batteries, but are actually like tiny contained nuclear reactors that activate and create energy upon sunlight absorption. His cells stop producing much energy under a red sun, normally produce power under a yellow sun, and go into overdrive under a blue sun.

Or he could just go hang out in the core of the sun, which he has done before, and gain absolutely massive amounts of power in seconds...

"he could punch right through a guy but never does" well do I have a comic book series for you...

or, hear me out, he could fly directly into the sun (which he has done in the past) to turbo charge his abilities. just saying.

Red star would diminish his power since it was this type Krypton revolved around. Blue, however, would increase it his power dramatically.

superman literally flies into the sun for power

*Batman watches this video* "So you're telling me Superman CAN melt steel beams! I KNEW IT!"

My only question is why his eyebeams never converge. They're always parallel, but if his eyes are focusing on a certain point shouldn't the beams meet there?

OOPS, some bad numbers, though good episode mostly, I'd love to see a revised/updated one :) . He stated the sun output 100PJ (1e17 J), but wikipedia showed the sun outputting 400YJ (4e26) in thermal energy alone, which is 4 billion times as much per second as he stated. As, like any sensible person, I don't entrirely trust Wikipedia, I looked further. NASA's Cosmicopia showed the sun outputting 380YJ (3.8e26) which is actually pretty close. I really really wish he'd do a new episode with this change :) This I thought important if we consider him actually flying into the sun (he's done that historically to supercharge). Please upmark this one if you do, too. Maybe he'll notice :) EDIT: FYI, the number used at Earth's distance was correct, so all that math was fine, just the sun's output was off, or he may have referring to the tiny fraction that heads Earth's direction. If that's the case, though, at a certain point flying toward the sun, his profile (and percentage of sun's output striking him, accordingly) would increase. If, for argument's sake, he were to fly into the sun and somehow absorb all output, he'd absorb in one second roughly 60 trillion Hiroshima blasts, or 1.8 billion Tsar Bomba blasts (biggest explosion we've ever made), or enough to heat the entire by 1 degree Celsius 400 times over... that's with a one second charge. That's just nuts... b/c science!

Wait, a Second, a Red Sun would take away Superman's Powers! It's better with a Blue Star ;3

It's simple. He has frickin' lazer beams attached to his frickin' head.

confirmed laser eyes can't melt steel beams, lex Luther did krypton.

He clearly absorbs a lot more energy than that since he charged super flare after super flare each day, and since it took 24 hours for his powers to come back it takes a lot less time for him to recharge.

Kyle, you are the best. Thank you for making intelligent and entertaining video-blogs. You make learning fun and your personality is what the school system is missing.

kyle, I love your delivery. keep it up. it's incredibly enjoyable and very informative.

At the end, your sun colors are backwards. A red sun releases less energy as they are slow burners. A blue sun however burns hot and fast, releasing way more energy.

I was hitting the like button before the video even started... awesome science stuff as always, Kyle. The brain flexing is greatly appreciated.

My lord your energy reminds me of Jake from VSauce

You're getting more and more fun to watch, Kyle. Sweet videos 👍🏽

new civil war trailer with spiderman

3:12 through to the next 4 seconds, the mannerism you employ to express the dementedness of what you are talking about, it is super adorable.

Can you do a video on Spider-Man's web shooters?

that double marker action seriously fucked me up D:

If superman went to a red sun he would lose his powers, thats a well known superman weakness.

I just love when kyles on here explaining all these things. I want kyle as president

This kind of videos deserve more views!!

Perhaps Kal-El's solar absorption cells are also biological amplifiers (utilising other energy sources to scale up the stored energy and shorten time required) Plus, the angle he is standing or flying in relation to the sun at a particular point on the Earth will affect matters too..Sheesh, complicated!

How long would it take superman to charge his heat vision to the same energy levels as the death star?

This video was epic. Subscribed.

Some questions: - how does his vision still work while the "beam" is coming out of his eyes ? How does he see and aim the beam ? - regarding the absorption of energy from the sun: can we get some details on that ? What if it's cloudy ? How about the material of the clothes he's wearing ? What if he's not directly in the sunlight, let's say it's a sunny day, but he's under the shadow of a building, how does it work then ? What about night time ? (the answers to these questions are important to me in more than 1 way, it's not only to get things straight on Superman, but also on how Vampires and their aversion to sunlight would work) - I like the calculation regarding how much energy he would need to absorb in order to power his heat vision, so how about calculating how much energy he would need to absorb in order to power his other abilities. Like for example his strength.. let's say he tries to lift 100 tons, how much energy does that require ? What about his flight ? How would that work, and what energy requirement would it entail ? - and since we've been talking a lot about Superman's different abilities that require power, how about his power storage ? How would you design Superman's "battery functionality", to have energy usable at his discretion, but also keep some in reserve for his basic functions ? What happens when he's not at full energy ? Does he have partial ability, or is he always at full strength, and when his reserves are fully depleted, he turns into a regular human ?

What about after 10, 000 years... while in the center of the Sun? (It has happened)

Man I love your channel 👍👍👍

I like how at 4:01 in the second full panel super man says "GG" 😂😂

I can't get enough of the special effects he put's on his videos

explain the science of your hair. Oh Thor Odin's son protecthor of mankind, guide our minds with knowledge

I'm a big guy, I could probably make floor mats for an SUV.

I think in "solar energy in his cells," the word "solar" means "sun-related," not "derived directly from the sun's radiation." If yellow sunlight modifies Superman's metabolism to allow perfect conversion of matter into usable energy, that would explain most of the absurd displays of energy release we see from him without needing similarly absurd charge times.

In some movies where it shows people teleport, there's a split second where they disappear before they exit their worm hole or whatever you believe causes their teleportation- my question is, would they get from one place to another instantly, or would there actually be that slight second of absence?

Imagine energy saving heat vision... Hippy superman

can you do a because science on NZT from limitless?

"From *gestures around eyes* to ... stuff." Perfect

Can we all just take a second and consider the fact that he is writing backwards so that we can see it... Impressive. Most Impressive.

I believe red stars actually weaken Superman.

I guess we're not gonna talk about how red solar energy completely depowers him

Superman just chills in the core of the sun.

Great video, but i was curious to know if there could be a scientific explanation about why his heat vision is red, mainly, or the color it SHOULD have in relation to the power he is releasing

Not cool guys. Copying a film-theory video they're going to do in the future.

Laser Vision can't melt steel beams

i learn more in this series than i do in physics class at school

I've always wondered how do the manage the writing on glass effect or is it just clever placement of glass and shot is mirrored?

Another way to increase the effective power of Superman's laser vision is to fire it into water, if done correctly it could split into hydrogen and oxygen then causing hydrogen fusion(this would take a LOT of energy to start up). Now that the fusion reaction is going he could harness the radiation from that and continue the loop. Essentially making a small star to harness for extra energy.

actually superman once went to the sun and stood there in a couple seconds and he was fully charged

The analogue effects so much better in the Reeve clip than the CGI crud.

Lol 😂 “from mmm to stuff” exactly

Heat vision doesn't melt steel beams

He's flown into the sun. I'm pretty sure that significantly lowers the amount of time he needs to charge up significantly.

"The average human body has enough skin to make all of the floor mats in your car"

Thanks and that was fun.

But, but, but......... Its specifically the yellow sun of our solar system that gives him his power. So one should assume that the yellow spectrum is the source of the power, not the full spectrum.

So Superman spends years on end to get enough energy to destroy a city. But when Goku trains for the same amount of time, he can destroy solar systems and even galaxies!

Honestly, I was more curious about what it would be like for Superman as he was shooting his heat vision. Would he still be able to see as he was firing, or does he just aim and hope? Would he feel any kind of pain as that kind of energy was blasting out of his face? How would he trigger the blast to begin with; would it involve flexing special eye muscles or simply concentrating? I suppose the same questions could be asked about X-Men's Cyclops.

Hey speaking of Solar Energy, can you do a really important calculation for me. In the Digimon franchise, a being called WarGreymon has an attack called "Terra Force" and what its descriptions said was "Takes all of the energy within the atmosphere and concentrates it into one spot, then fires it as an extremely dense, high-temperature energy shot." How much energy would that require to make the Terra Force attack?

The red star makes him normal right?

Superman can fly faster than the speed of light. I would think that him hitting someone at that speed would do more damage than his super flare attack would do. I mean wouldn't superman be splitting billions of atoms just by hitting them at that speed? That sounds more powerful than the super flare does to me.

Funny thing is that in the comics Red Sunlight zaps superman of his powers. I think he kinda of knew that I was just making a slight joke at the end...which would explain the grin

dude.. i know if off topic, but.... you guys should totally do a Because Cience of How to train your dragon... how big a dragon must be for a person to ride?, how a two headed dragon would work?, is it actually posible for a species to have 4 legs and 2 wings?, would it be possible for a dragon to sweat something for covering itself in fire?... Toothless echolocation, acid spit, the nadders spike tail, the stingers paralyzing shot, the thunderdrum sonic blast... there are lots of material that could possibly hold some real viability

one problem when u said a red giant his home star was a red giant so he would have no powers if that was the case

Don't red supergiants actually weaken superman? I knows it's a red star of some kind

Really though this is how all of Superman's powers should work... I wish they'd do a part two of this applying these rules to strength, flight, speed, and durability via stored solar joules. I know Superman never follows these rules but a superhero who did would be far more interesting....

Superman could just take literal sun baths

5:25 So all the women at "The Daily Planet" would have breast cancer?

Did anyone else see Kyles sloppy handwriting and think: Time/s) and get frustrated? Tighten up that parenthetical!

I know these comments are for this video but I would like to make a suggestion on a video that you could possibly make. How much pressure is exerted from Spider-Man's web shooter and would it be a dangerous amount of pressure if used to help a falling person? In the movies and comics we see Spider-Man saving people by sometimes using his web and as it makes contact with the person it shows them to have no affect by it at all unless it would be a thief or a crook. This is just a suggestion and you could change it up to make it sound more sensible.

Dude Superman’s powers have been developing since he was on earth.

but superman poeple dont have power in a red sun

it's because of these because science videos I was able to pass my physics test

Could there be any science-y stuff in shape-shifting? Like werewolves and other creatures? That would make a cool video, I think.

"Quarter mile"? One thing that I've enjoyed about this video is the use of metric weights and measures that I can actually understand instead of archaic pre-metric measures that some other videos use that I understand about as well as Old English (i.e. pretty much not at all... actually, I can understand Old English a lot better because a surprising amount of it still survives in Modern English with relatively little change if any)

The diagrame just made my math brain melt, the line for the minute was as long as the year! Great video tho

the question is how strong do your eyes have to be in order to handle that kind of energy plus exerting it from the eyes

Supermans eyes are so Dank, they can melt steel beams.

kyle hill is the master of back writing lol

Love the Science !!

I always thought that Superman's X-ray vision was just his eyes being able to view the natural X-rays bouncing off stuff like our eyes can see visible light bouncing off stuff.

Superman is just able to see in the xray spectrum like we can see in the light spectrum, but xrays can go through objects and look different. Maybe for him to look at a solid object, is like looking at an aquarium. There are usually minor xray emissions in our environment which is normal and doesn't harm us at all, which he can see, right? So he doesn't need to emit xrays to see inside an object and doesn't harm you, because instead he sees them, as they are coming in from various sources and through objects, interacting with those objects and then into his eyes. Although if he wanted to see through something really dense, he could fire lazers out of his eyes in a wide dispersal area, in the xray spectrum and see those partially reflected back into his eyes.

2800w but voltage and amps make a difference. so what are those values? How many ohms i can decipher if i have those values, and is the resistance what makes the beams (ohms make heat )?

Can you answer how The Iron Giant's digestive system/metabolism might work?

Hey Kyle, what about all the flight take offs landings jumping/landig

There was a stint in comics that Superman meditated in the center of the sun... Hahaha

You didnt actaully explain how it works, you just told us that he stores energy and releases it.

Can we all just stop and recognize Kyle's one hand dual marker holding writing skills?

I was kinda hoping you were gonna explain HOW he does it; like the mechanics of doing it, rather than how much energy is used when he does it Either way, I was informed and entertained. Sub.

No homo: Man I love this guy. He's always in a good mood .

Imo the calculation of superman energy absorption can only be applied to the moment he gets out the ship and is on earth , u gotta remember he has stored energy from all his life of being in the sun that he can call on and that grows every sec he is alive, plus the times he's been in direct contact with the sun , BUT ...when he gets out of his space craft and is on earth this is applicable, and the part i cant back up but i think his cells amplify the power he absorbs as well

@Nerdist Shouldn't the diagram supposed to look like a linear function? Or was it just a sketch for better illustration?

time 3:15 is the first reason why i gave this video a thumbs up. yes. this guy. yes.

Wait how does his energy absorption work ? could we possibly get a video on it ? like can he control it or is he just absorbing it every time he is in the sun ? please explain

Nerdist Could you do Superman's flight ability? The original jumped. So his power was strength. Modern Superman flys , so is his power based in pysonics , does he vibrate himself and the air around him , or is a directional release of solar energy?
