First I want to apologize because English is not my native language but i want to explain the flow of time with physical theories sorry for my grammatic
I have another explanation about time travel, dimensions, singularity , well in physic time travel can be done but only in future no one can travel to the past because travel to the past means break the relativy law but einstein theory prove time travel to the future , so the gang (chrono, marle , ayla serge ...) can travel to the future (you must put 1000 Ad like the current present) so if 1000 is the present that means every change that chrono or the other made in the future is possible because they created a virtual future (a virtual future is like a prediction because is only make truth is no one change the future again , an example is chrono killed lavos and everyone is hapyy but what if lavos reborn inmediatly after his death which is highly improbably but that means that future donīt change at all even if chrono killed lavos so like i said is a prediction no one is sure if the future is seal) so every change make after 1000 ( guardia fall, lavosīs death, chronopolis) they are only a virtual future so Chrono trigger time line is the beginning of every possible future (if 1000 is the current present ) so if chrono croos began after 1000 that means that chrono croos is like a continuation of chrono trigger (i repeat is a continuation because is the virtual future ) now why did chrono travel to the past if the past can not be change) well that easy when the travel to the past that past was not a time line that means that every travel is only a different dimension that explain why marle donīt die after travel with ayla to the future and also explain why in this game has so many endings so in conclusion chrono only travel for different dimension and the change that produce in his current time is not his truly world, in the end chrono live in another dimension and the chrono of the first dimension (the first dimansion is the one in the beginning of the game , when chrono disappear from the first dimansion means that chrono real mother is sad because he lost his son.. poor chrono he dumped heīs real mother) so that explain why when marle died lucca or chrono domnīt die with her after all if the queen of guardia die then magus win the war then lucca and chrono never exist so every travel to the past is not a time travel is truly a dimension travel now for explain dimension is easy because exist a law, we sopuse to live in a 4 dimension universe that is not a complete truth (see quantum theory) when the bigbang create a universe it also create several universe like 1 dimension universe or 2 ,3 ,4 ,5 ,6 but we can't see them because they are hipercurved (if you want to know more see hawkings book or penrose books ) so a aislated universe is possible and then jump from one universe to another is possible ( like movies when they travel to hiper space the must travel for one universe to another if they do that they can foul time line and travel long distances without breaking any physical law (we canīt because our multiples universes are so small and curve ) another thing if we want to explain aslated dimension like lavos dimension (because he can make created time warps ) he must be in a place where the timeīs flow is almost Zero but how can be done? , that easy gravity curve space and time (if we live in the sun we can live more becouse the time flow is slower than the Earth time flow) so if gravity curve space and time a high concentration of mass in a small space of the universe can make that happen but if that happen gravity will destroy lavos becouse is to much gravity for any living thing but we can make gravity weak ( this is why i love chrono because when i Fought lavos the only thing you saw is lavos and a blue space so so the only thing you can see is three dimension objects is easy to sopouse that in lavos dimension is equal or higher than 3 , like a point or a line exist in a 2 dimension universe but a cube can not exist in that universe but a cube can exist in a three dimension universe ) so if lavos live is in a singularity and we can make gravity weak then we explain lavos dimension but for make gravity weak we must create a universe with more dimensions , in conclusion if lavos lives in a 4 spacial dimension the gravitry is only 1/6* in compare with a 3 dimension gravity with the same amount of mass (* iīm not sure if is 1/6 ) so in a X dimension world with X higher than 3 is possible explain why the gravity didnīt kill lavos or the others and the last physical explication of chrono is why in the same game porre defeat guardia but guardia is the ruler of the 2300 Ad well the physical explication is .. ( the game is wrong that is impossible LOL)
that my explication of the chrono games i apologize again for my grammatic
