Of course heavy gravity from that of Krypton is not why he flies, who said it was?
"There is some theory that gravity is carried by subatomic particles
that are called gravitons. Gravitons are something we have not
yet detected... theoretically they will travel in waves much like
light waves or electromagnetic waves. If Superman has a way
of generating gravitons within his own body.. assuming
gravitons exist. He would be flying by essentially riding
by waves of gravity in his immediate environment.."
No...... it's the dense molecular structure that allows him to absorb energy from a yellow sun. The radiation just meshes well with his makeup. Humans have a less dense structure, and under a red sun, we would most likely just fry....
umm, no well... we would dress better than the natives of Krypton.. that's for sure! So, maybe we could bring flashy clothes, trade them for services rendered... then bring them to a secret underground lair here where we could hatch plans for complete and total world domin.... must supress the inner Lex... ok short answer... no
Actually I think the way it works is that Kryptonians are already kind of like solar batteries, but even so I believe the logic works in the manner that he came from a yellow sun world his anatomy is adapted to a much larger heavier planet and the kryptonians had long since reached physical and mental perfection. It is also said that they had eradicated disease and hunger. Maybe the reason he cant get sick is because of the kryptionian genes some kind of omni vaccine, and maybe the reason they dont have to eat is because they found an alternate way to gather energy that the body needs( maybe some kind of method resembling photosynthesis) that allows them to absorb solar energy directly through the skin. When a Kryptonian comes to Earth they recieve alot more energy from our yellow sun causing a massive increase in the energy they absorb and thier physically perfect bodies that are now adapting to earths lower gravity they become god like in ability. I think the other abilities come from the absorption of solar energy and allow him to super cool his breath and super heat his vision.
but then again its just a theory and what the hell do I know?
It just came to my attention that on numerous occasions or at least one BatMan was able to beat super man by exposing him to red solar energy. I think I can explain why
A) BatMan is about as strong as a man without powers can be
B) SuperMan was cut off from yeloow sunlight and exposed to artificial inferior red sunlight that he began to absorb. So he got the effect of being back home on krypton but he didnt get the normal level of nourishment so under these circumstances he is only about 1'10 as strong as the average kryptonian would be on the planet krypton.
think about it if the gravity is greater he should still be about 10x stronger than BatMan at the very least unless he was weak kinda the way a human is if he is starved. I f you go 2 or 3 days without eating I bet youd be too weak to lift a bag of ice. Where as if you were at full energy levels you could probably do it with one finger.
Basically when BatMan beats up red solar power induced SuperMan hes beating up a helpless starving man while he is at the peak of non super abilities......... What a bully.
okay. back to the topic... one thing everyone should know is that when kryptonians lose their powers they become average human beings. they dont have any extra photosynthetic organ or something of the sort. their skin become as soft as ours. THEY BECOME COMPLETE HUMANS.
so my theory is that since red suns make them human and yellow suns make them powerfully super human, there's no reason why we shouldnt be as powerful as them under a red sun.
excuse my fist... it thinks you belong with the dirt on the floor...
I'll tell you what guys. Kryptonians deffer from Gods in one way, their abilities are physical while any god controls the will of people and time itself which is greater because the know how to combine them. S can only alter a small time frame but nothing on people's way of behaving.
Actaully we would gain powers just like superman according to comic books. In the present situation maybe not. But When Spiderman battled Superman that was how he was able to fight him. Lex Luthor exposed him to red solar radiation and he even said that a red sun would give us the same powers
Going back to DC Comic book stories, I can tell you that Dc for sure retconned out the existence of humans having powers under a red sun. But they did create the comic storyline of mighty boy, a human named Thomas Keith sent into Space by his Parents in a home made rocket which accidentally landed on a Planet Zumoor where the radiation from that Planet's golden lunar moon rays amd lower gravity bestowed on him Kryptonian like powers exactly matching those of Superman. He was later renamed Zarl Kazzan by his adoptive parents on that home-world. It was further explained that the radiation of the golden lunar rays gave humans a version of the same meta-genes Kryptonians have under a yellow Sun granting us humans super-human like abilities. Dc never retconned him out of existence until Infinite Crisis and New 52.
