What is more reality, space or time? TreBert
The extreme complexity of code yet undetected within DNA should beg the ultimate question as to where such complexity started, because it sure as hell didn't originate on Earth, as from any amount of complex chemical or raw element interactions that has been uncovered, or much less artificially devised from scratch without a great deal of applied physics and technology that nature simply couldn't possibly simulate.
Just like those extremely odd geometrical formations identified on Venus can't be easily explained away, other than by applied naysay, FUD, obfuscation and/or absolute ignorance.
Be my guest and apply your very own photographic enlargement software, as to viewing this one small but rather interesting mountainous area of Venus, using your independent deductive expertise as to enlarge or magnify this extensively mountainous terrain of Venus that I?ve focused upon, really shouldn?t be asking too much. Most of modern PhotoZoom and numerous other photographic software variations tend to accomplish this enlargement process automatically (including iPhone and Safari image zooming), although some extra applied filtering and thereby image enhancing for dynamic range compensations (aka contrast) can further improve upon the end result (no direct pixel modifications should ever be necessary, because it?s all a derivative from the original Magellan radar imaging of 36 confirming radar scans/pixel, that can always be 100% verified).
