The galexy where cooper and team reaches contains a black hole and planets.Where NAZA considers to may have life on it and it shown that every planet they reaches has an atmosphere , light , days and nights. How can that be posible??. The black hole situated in the galexy where there was an active star more than a billion years ago the light source which gives the light, now it is has dead. that may also result inthe death of the planets too. it has became a black hole. then how the planets gets light ?? how does the day comes??
A black hole even attracts the light rays then how the planets had days. Even if you consider about a situation like there is a star adjecent to in the galexy. still you can find it can not happen at all. A black hole with another star adjecent is a 0% considerable. Two stars in adjecet is also cant happen at all .You can find why it cant by having a look at the process how the stars are born. I think this might be the biggest negative spot on the script.
