A theory has been extensively tested and is generally accepted, while a hypothesis is a speculative guess that has yet to be tested. another example of a theory is the famous Theory of Relativity. its only a theory but widely used world wide from semiconductors and computer chips, nuclear magnetic resonance leading to MRI imaging, particle accelerators leading to beams for cancer treatment to Global Positioning System Satellites.. but, no one contradict it because it didn't cause any trouble in any belief like the Theory of Evolution.
May mga bagay na hindi natin kayang maunawaan, at isa na dito ang tinatawag na "Different Dimension", tayo ay kumikilos lamang sa tinatawag na material dimension, isang daigdig na binubuo ng materyal na bagay gaya ng mga bituin, planeta, mga ulap at alabok na matatagpuan sa sansinukob. Napakaluwang nito at tila ba walang hanggan.
