why do we feel the heat from the sun right away how fast is the sun ray?-------------------------------------------------------answers:Achal say: It doesnt reach us right away.It takes approximately 8 mins to reach earth. It travels at the speed of 299792458m/s.It is able to reach us as the sun is very hot (It has a surface temperature of 5778 kelvin).Since space is a vacuum there is no loss of heat due to other factors.......

Achal say: It doesn't reach us right away.It takes approximately 8 mins to reach earth. It travels at the speed of 299792458m/s.It is able to reach us as the sun is very hot (It has a surface temperature of 5778 kelvin).Since space is a vacuum there is no loss of heat due to other factors.The only factor which which reduces heat is distance.So it can radiate heat over very large distances

Tom say: You are feeling the heat from 8 minutes ago. And it is still coming. it never stopped, so you don't have to wait for it. We are and have been heated continually. The light from the sun travels at Light speed, so it takes over 8 minutes or so to get here--over 93 million miles. Meanwhile we are bathed in the light that already made the trip.

Philomel say: A light ray travels from the sun to earth 93 million miles in 8.5 minutes at the speed of light so it tends to get very hot due to friction.
-
say: You receive a ray which was initiated 8 minutes ago.

oldprof say: You don't feel it "right away." It takes about 8 minutes for that radiant energy to travel from the Sun to the Earth.

But here's the deal. It comes continuously like a stream of water from a hose. You know that water takes time to get to the flowers you're watering but once the stream gets there the flowers are continuously watered.

Well you're continuously sunned. (I made that verb up.)

And here's another deal. If the Sun were to suddenly disappear from space we wouldn't know it until 8 minutes later. Then, 8 minutes after it's disappearance, it would suddenly go dark and cold. And the Earth would no longer be in orbit it would travel out into deep space. Why? Because gravity waves also travel at the speed of light, like the sunlight does.
