5.5 billion years have passed and the sun is now in late 50's. the period left for life in this solar system may be upto 5.5 billion years.. As newton predicted that the planets will leave their orbits when sun will be destroyed at once. later einstein argued and was proved right as it takes more than 8 mins for light to travel from sun. What will happen after 5.5 billion years? certainly everybody will answer there will be destruction. but the fact that light travels by 3lakh kilometers in one second matters much...
As history predicts the fuel in sun will slowly get finish.. the earth is warm because of the presence of atmosphere. this atmosphere is formed because of sun's uv-particles. it will known after 8mins about sun's destruction on earth while 43 mins for that of jupiter.. this time difference is because of distance. the gravity of the cellestial objects having mass aftects the passage of light but not the speed. suppose this is the last photon travelling from sun with velocity of light. for a person siting on that photon, the nearby time is stopped. suppose that photon is passing infront of obj..A then for the observer at A it will be with the velocity of light that the photon with person is passing. and for person it will be different. but the time outside will be going as normal... but when light particle passes, it will be dark.. WE even cay say that it is time travel that light from betelguesse is coming to us from 1500 century. also the many objects in the center will be changing direction of light because of gravity. when sun will be black hole with strongest gravity.. Time on earth is because of light and as there will be no light,there will be no time.. if light from other galaxies come in our solar system the time will start but soon it will end because of black hole and if continuously light is supplied and absorved by sun and object 300000km far away then it will be 1 second for sun with frame of refrence of the other galaxy and time will be matched.but for some more objects like earth, earth's time will be different than the sun. it will be ahead by half a second. thus the more farer object from sun the more time difference.. we will follow time and time will ticktick.. but the light reflected from sun reaches on earth in half second then earth will be half a second back than sun for that photons and ahead for direct photons.. This is indeed surprising.. this indicates that for today the light that we are receiving from sun,,, sun is 8 mins ahead but light from betelguese with more than 400 years old for earth is more than that from sun.. so we are ahead.. so destruction of sun will result that the sun ahead from us will be back than us as light is passed from earth...
INDEED THE FIGURES TAKEN IN THIS EXAMPLE ARE ROUGH. ACTUAL FIGURES RESULT DIFFERENT..
so there is a mystery !!!!
and if some black hole is formed between earth and sun then the time on both of this planet will stop with frame of refrence to each other but for some other object their will be relativity.. SO THIS IS A CONCEPT OF FRAME OF REFRENCES!!
so time is endless and if universe contract we will get older and older with time running normally
