I know that mass can bend fabric of space-time, which causes gravity by making an object curve around a planet or star but is there anything else that can bend it?

Other energy sources, forces anything?

In addition to mass (energy), tension and pressure can also act as sources for gravity. All the sources are encapsulated in an object called the energy momentum tensor as described here

more simple terms? so does this mean mass and also energy can bend space-time? – Nick1o2 Nov 2 '12 at 9:54
Yes energy, such as radiation, also acts as a gravitational source. – twistor59 Nov 2 '12 at 11:50
