So I request YOU explain and you refer me, without even a link, to Read up on "relativity of simultaneity" Not sure how many hits such a Google would throw up so will pass Decided not to pass and clicked on the first link thrown up https://en.m.wikipedia.org/wiki/Relativity_of_simultaneity Of course two observers are going to view a event occuring at different NOWs depending on their RELATIVE positions They can also have different views of something and when asked to give a description provide two completely different descriptions. Why? Well one was looking at the front and one at the back If there is not ONE single NOW for the entire Universe that would mean parts of the Universe are either operating in the future or in the past Think of the Universe as a extremely complex watch, with billions of cogs. All cogs are in operation due to being linked. Some cogs, large, complete a rotation every 10 years and move to slow to register. Small cogs rotate fast almost blurring their movement. But all cogs do move Lags in NOWs are dependent on the speed of light transmitting the information Lags in cog movement depend on the speed of the deformation of the cog material If you consider there is NOT a Universal NOW you should concede parts of the Universe operate in the future and parts in the past Please Register or Log in to view the hidden image!
