WE KNOW THAT SUN GRAVITATIONAL FORCE IS MUCH HIGHER THAN EARTH'S GRAVITY,SO WHY LIGHT BEING EMITTED BY SUN COMES TO EARTH ,THE EMITTED LIGHT SHOULD BE ATTRACTED BY SUN THROUGH SUN'S HUGE GRAVITATIONAL FORCE REMAIN THERE IN SUN?PLEASE EXPLAIN.

Properties of Sunlight:
- Sunlight travels at the speed of light.
- Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes.
- The Sunlight takes an average of 8 minutes and 20 seconds to travel from the Sun to theEarth.
- The radiant energy is carried by packets of light called photons.
- The photons are bundles whose energy depends on frequency.
- The radiant energy corresponds to a range of wavelengths on the electromagnetic spectrum, of which visible light is only a small portion.
- Sunlight at Earth's surface is around 52 to 55 percent infrared i.e above 700 nm, 42 to 43 percent visible i.e 400 to 700 nm, and 3 to 5 percent ultraviolet i.e below 400 nm.
 
- Reason why the sunlgith reaches the Earth even as the Sun's gravity is much higher than the Earth is because it transmitts electromagnetic waves.
- Electromagnetic waves have very less mass.
- The gravitational pull directly corresponds to the mass of the body.
- And therefore, this negligible mass of the sun's em waves allows them to escape the gravity of sun and travel towards the earth.
