Can gravity bend light? If so, how?
1 Answer
Yes, it can!
Explanation:
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:
