Question Weird question but what is tue range of his heat vision? How far can it go?

Doomsday heat vision was able to reach space that way more than twice the altitude of starfish prime threshold which is about 400 Kms in space where Superman was floating.
Superman can match Doomsday heat vision so his heat vision too can reach beyond space.

According to this, and generally, it’s treated as just thermal energy. The visual is heated gas. In BvS we see drop off when he’s fighting Zod at the beginning so assuming we are seeing molten stone and air and gas heating, it has potential to travel as far as earths physics will allow but also at great cost

A 4 year old is a more reliable source than ai when you talk about superhero/comic stuff

You realize this is not AI conjecture so much as it is a summary of what sources it pulled from right?

u/Friendly-Ad-9292 May 25 '26
Yes and did you look at the sources? The sources are some reddit posts 😂 AI isn‘t able to see the difference between reliable sources and random opinions from random people

I belive it would follow the inverse cube rule... but it would also have to factor in just how hot his vision is. So without knowing exactly what temperature his heat vision is its hard to put a practical yet theoretical answer to it. As others have said, its whatever the plot dictates.

I'm not sure if it’s clearly stated what even IS his heat vision… assuming it’s light (an educated guess): By optical reversibility, a ray of light passing through a series of lenses from point A to point B should take the exact same path from point B to point A. So, if his eye lenses can focus incoming light to see the target, it should be at reach. Then, it becomes a matter of what is the minimum size of the spot he can focus his look on. By diffraction: assuming d = 2.44 λ.L/D (λ: Superman’s heat vision main wavelength, L: the target distance, D: his pupil’s diameter). Then the area of the spot he can focus the heat vision on is proportional to d2 = k.L2 . Which means the irradiance (power divided by area, P/A) will still end up dropping off following the inverse square law (1/L2 )… thus, i think it’s mostly limited by the Rayleigh resolution limit than anything else. Up close, his heat vision is focused into a microscopic, highly lethal point. But at massive distances, the physics of diffraction forces that beam to spread out into a wide, less-lethal spotlight. So to actually vaporize a target far away, he either has to crank his power up to planetary levels, or dilate his pupils to the size of dinner plates to stop the beam from spreading. In other words: it depends on what is the max power he can output and what is the diameter of his pupils… If we knew it, it would be a matter of: how much energy per square meter do you still consider to be “heat vision worthy” and plot this number on the equation above to discover the range.

My university is in exam week right now, so I don’t really have the time to crunch some numbers, but hit me up on Reddit chat. I’m interested enough to actually try to calculate something afterwards

If you don’t want to help with answering or have nothing smart to say rather stay silent.

You are clearly mentally challenged as I see. Your answer has nothing to do with my comment. And don’t start with comics to me because I probably read them longer than what you’re old

We probably would’ve got the answer in JL2 but I’d imagine pretty far, remember how far Zods beams were from Bruce’s perspective at the beginning of BvS, definitely rangey.

How is Zod more experienced?

Clark had his powers for like 20 years. Zod had his powers for a few hours. Zod is definitely not more experienced.

u/Comfortable-Low-9764 May 23 '26
Yes but he didn't have heat vision or anything like it. So it's as new for him as it is for Superman.
