## Is time linear or curved?

Time itself is **neither linear nor circular**. It does not flow or move but allows others to do so. So the cycles we observe have nothing to do with time, except that time will enable them to exist.

**Does gravity bend light?**

While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity. This is not because the mass pulls on the photons directly, but instead because the mass warps the space-time through which the photons travel.
