You see images of more advanced beings or aliens with big heads… maybe the ore advanced being would have developed brains that can do more with less… so their heads will be smaller… O_o
Brains require a lot of fuel, so you make a good point. A bigger brain is not tenable. More likely, advanced life forms may have figured out how to augment their brains with outside technologies. We’re not far off from that right here on earth.
All we have to do is figure out the brain to machine interface. It sounds more sci-fi than it is in reality. We already have it, the only thing is the interface right now is through the finger tips and eyes.
If we can remove the fingertips we’re a step closer.
What will be interesting is what we do with our new found powers, if anything. Are heads won’t be any bigger physically, but they will be metaphorically. May we be wise and artful, and respect truth.
the reason for the popularity of big-headed aliens is the area 51 conspiracy. some widely-circulated photos account for it.
Problem with tech advancment I see is that leaves the opening for viral attacks on our mentality…and mind control…
