Imagine that we go inside a black hole then it is said that as our speed increases time decreases and after that time comes to past , is that true ?
Although I read that IQ is a constant value and can not increase after the age of 10 years , but why every new IQ test giving new results , with the same person ? If it is , then how can we trust , on anyone 's IQ is constant or not ? or Is it can be increase or decrease by the time ?
