Not necessarily, a lot can reverse and pump the heat inside

They have momentum, but not mass (ignore the other explanation, like yes, E=sqrt(m0^2c^4 + (pc)^2), but so what? m0=0 for photons)
As you can see, momentum, p, is p=E/c, and we know that the energy for light is proportional to its frequency, f, E=hf (h is Plank’s constant). So, p=hf/c. When light is absorbed by a material momentum (and energy) conservation apply and it imparts p onto the object. If light is reflected it imparts 2*p, showing this is left as an exercize to the reader

twincest cannot cause more abnormalities than “regular” (gross) sibling incest. If a set of twins are of diferent sex they are not identical, ie they come from different sperm and different egg. Same as any sibling pair
