Morals depend heavily on culture, and cultures often have conflicting views of what is immoral. To me that alone suggests there is no such thing as an objective morality which is somehow inherent in the universe.

Anyway, according to physics what we will very probably end up with after we've all been incinerated by the Sun or frozen to death for lack of light if we keep managing to avoid incineration is the utter destruction of the universe into loose photons so far apart from each other that there's no putting them back together.
