Einstine theory today after long time I am trying to write a note book entry. Its about Einstine. He was a great scientist. According to him time is not constant in the universe. so this proves that there can be some place in the universe where rate of flow of time will be very slow and also a place where rate of flow of time is very high. so if we went to place of slow rate time may be we will die after thousand of years and if we went to fast rate reason of universe may be we will die in few seconds in that place. So according to me its really a great concept . He also told about gravity and matter these both are not constant . Matter and energy can be changed back and forth. so if possible please correct my notebook entry
