Can gravity bend light? If so, how?

Answer 1

Yes, it can!

According to the Einstein's Relativity, Gravity is because of the space and time continuum. The space time is like a grid which by gravity gets curved or bend. See this image below of Earth curving space-time:

Now, by this. Gravity works that if anything comes near the curved area, the object falls towards the object that is curving the space time.

Anything that have mass is somewhat attracted by the gravitational force. But how then light gets bend?

We know there is huge giant creatures in the universe know as black holes. What they do is that they curve the space time so immensely that even the path of light gets curved. That's why we can't see black hole but there behavior with light.

I strongly recommend you seeing the movie Interstellar which have shown black hole's bending of light:

Yes, gravity can bend light, a phenomenon known as gravitational lensing. It occurs due to the gravitational field of massive objects, causing the path of light to curve as it passes near them.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
