I apologize if this has already been asked before (seeing as how there are 36 pages), but does Hinduism have any kind of end-times prophecies like we see in Christianity? Does Hinduism teach that some great change will happen in the world at large some day? Will this world have an end or will it last forever?
That is a good question
Hinduism does teach that the universe ends but not in a prophecy - more like an explanation of the laws of nature.
We are told that the world experience 4 main Ages, the last of which we are currently in. After this Age ends, the universe is destroyed. But we believe that the universe cycles through creation and destruction so that after its death, it is re-created and the evolution of life begins again.
These cycles are infinite.
