Can light bend the space fabric?
The space fabric can bend light due to gravity
It is interesting to speculate if light can bend space. We know that light can be bent by the space fabric.
Yes, light can bend the fabric of spacetime.
Einstein's field equations of General Relativity look very simple:
The equations are far from simple. It is actually 10 second order partial differential equations which are very hard to solve. The left hand side is the Einstein tensor which describes the shape of spacetime and how it tells matter and light to move.
We know that the equation
As light has both energy and momentum it too must cause spacetime to curve. The effects will however be very small.
