astronomers are able to calculate a star’s life expectancy depending on its mass. (a larger star burns more gas, therefore having a shorter life span).
so astronomers can definitely predict the death of stars and the times they will die.
i hope this was in some way : )

The scientist was trying to demonstrate that humans can introduce their own biases into an experiment. bias is a prejudice in favor of one thing compared with the another.in this case, the bias is believing that mice with higher intelligence would solve the maze better.  bias in science should be avoided as it is not desirable that research becomes influenced by scientists personal beliefs.
