Anti-relativity and Superluminality

Let me start with sound. Is sound real? One cannot answer that question without first defining, in some sense, what sound is. When a tree falls (as in the over-used conundrum), it creates some pressure waves in the air. If there is somebody around, then the pressure waves hit their ears. The ears perform a spectrum analysis and send the corresponding electrical signals to the brains. And in the brains, some neurons fire in some specialized areas. This is the whole chain. Pisikal na, there is nothing more. We have a falling tree, pressure waves, electrical signals mapping frequencies, some neurons firing. Where is sound? Sound, sa aking opinyon, is the magic that the brain performs. Is it real? Sa palagay ko, hindi; it is just a cognitive picture the particular evolutionary process that we are part of chose to equip us with. It is a mapping of our auditory signals.

Sa isang eksaktong parallel, we should think of space as a cognitive mapping our brain creates out of our visual inputs. Totoo, our touch and auditory senses provide some corroborating evidence to this picture. Just as the pressure waves created by a falling tree are sound only if we are there to hear it, the random photons floating around are space and a universe with stars and galaxies only if we are here to process them.

I know this argument may sound a bit abrupt. Pagkatapos ng lahat, I wrote a whole book dealing with this notion, and I’m not sure I convinced anybody yet! Now the real interesting question is, are there photons or pressure waves to begin with? Ang mga ito ay isang bahagi ng nagbibigay-malay picture lumikha kami para sa ating sarili,,en,isang bagay Leo makatwiran nakaumang out mas maaga,,en,bumabalik sa tanong ng 3-D space,,en,Naniniwala ako na ang ating binokulo paningin talagang nagdulot ng ating utak paglikha partikular na representasyon ng 3-D space,,en,Kung nagkaroon kami lamang ang isang mata,,en,utak marahil woulda € ™ ve nagbago ng isang larawan kung saan ang mga sukat ng isang mandaragit na kumakatawan sa mga antas ng mga kaukulang panganib,,en,Tulad ng ang intensity ng tunog ay nagbibigay sa amin ng isang palatandaan bilang sa kung ang distansya ng ang pinagmulan nito,,en,ito ay ang lahat ng aking haka-haka,,en,Leo,,en,mong isulat simulation programa,,en,Wonder kung maaari mong malaman kung paano paniki ay mapaghulo motion gamit echolocation,,en,Aking hulaan ay na ito ay magiging eksaktong katulad ng espesyal na relativity na may bilis ng liwanag papalitan ng mga bilis ng tunog,,en – something Leo rightly pointed out earlier.

Ngayon, coming back to the question of 3-D space, I believe that our binocular vision really resulted in our brain creating this particular representation of 3-D space. If we had only one eye, the brain probably would’ve evolved a picture where the size of a predator representing the level of the corresponding danger (halimbawa). Just like the intensity of sound gives us a clue as to the distance of its source. Oo naman, this is all my speculation…

Leo, you write simulation programs? Wonder if you could figure out how bats would perceive motion using echolocation? My guess is that it would be exactly like special relativity with the speed of light replaced with the speed of sound.
