Light takes time to reach earth but according to Einstein it should not right?

No; according to Einstein it should take time for light to reach earth from the sun. Light is not instantaneous. The trip takes about 8 minutes. You may be confusing this with the theoretical result that if you were able to accelerate to the speed of light (you cannot) then for you, time would stop passing. You'd still be traveling at light speed, but you would have no experience of the passage of time. If you attained light speed and maintained it for 1000 years as observed from earth, you would decelerate to find that 1000 years just passed by on earth, as if in an instant, and you would find yourself very, very far from where you were only a moment before (from your point of view). This goes against what our intuition tells us about time; it is a 'relativistic' effect. And by the way, you would not have aged a moment over the thousand earth years you spent at light speed.

When should you use light years?
Light years are used to measure distance from Earth to distant stars and planets.
What does a light year have to do with the sun and the earth?
A "light year" is a measure of distance, derived from "how far light can travel in one Earth year". Thus, if you shine a torch for the amount of time it takes the Earth to orbit the sun exactly once, that light would have travelled the distance of a "light year".
Can you prove the moon goes round the earth?
Yes Yes, you can because the N.A.S.A prgram has a satellite in space and they can monitor the planets and the moon, so yes you can prove that the moon goes around the earth and the moon is always in the sky every night. =]]] Depends from where you look. According to the Einstein's theory of relativity ... If you stand on the moon, you will find the earth orbiting the moon and so the other heavenly bodies... BUT Earth, being greater in mass... almost 5 times more than our moon ... the total gravitational force of earth is more than that of the moon... almost 5 times more... Hence we consider that the moon is orbiting the earth. Because, generally, More the mass, more stable the object. So if we consider that the earth, having 5 times more mass than moon, as stable or stationary... We conclude that the moon orbits the earth.... But I feel Einstein's Theory of relativity more accurate. Also if we view the phenomenon from the sun, we will find that the moon orbiting the earth, because earth is orbiting the sun...IF WE ASSUME THAT TOO.........ACCORDING TO THE MORE MASS ... MORE STABILITY TECHNIQUE.
How long does it take a star's light that is 7 light years away from Earth to reach Earth?
It's exactly 7 light years away.One light year is the distance that light travels through space in one year.7 of those is a distance of something like 41,150,289,900,000 miles.
Why does earth revolve around the sun in term of physics?
The simple answer is that the earth is close enough to the Sun to be within the gravity influence of the Sun. This Gravity influence is like a "rope" from the sun to the earth which keeps in in a circular path and also keeps it from pulling away from the sun. The real reason is better explained in light of the Einstein theory of General Relativity. That implies that the mass of the Sun has caused a curvature in spacetime that the earth rides in, and as the earth tries to continue in a straight line this curvature of that spacetime keeps the earth speeding around the Sun in a continuous elliptical orbit.
How far away is Einstein's cross from Earth?
8 billion light-years.
Do I grow older faster when flying?
According to Albert Einstein's theory of relativity, flying at the speed of light will cause you to stay the same age. Flying in a jet or airplane here on earth will have no noticable effect on aging.
Why does light curve on the earth?
Picture the fabric of spacetime as described by Einstein; bending around dense objects. Light on Earth curves because of the Earth's gravity, the way Earth warps spacetime. While you hear the bending of light mentioned most often in relation to black holes, any gravitational field can affect light - although not as much as near a black hole!
According to Einstein when you jump down an airplain it is actually the Earth that rushes towards you. why so?
I doubt that this is an actual quote from Einstein. The idea doesn't sound much like Einstein, either. Einstein might have indicated that you and the earth actually fall toward each other, although the net effect on you is much greater. Or he might have talked about the warp in space that is created by a gravitational field, and it is the warp that pulls you toward the earth. Any observer from any vantage point would clearly observe that the earth doesn't make any special movement in response to you jumping from a plane.
How many People Live in antarica?
none, antarica isn't a place on earth. -Albert Einstein
What was Albert Einstein an expert in?
he was an expert in earth and it poles
What percentage of brain had Einstein used?
According to sources Einstein's brain was removed within seven hours of his death and within next 24 hours this was declared that he used 14% oh his brain and he is first on earth to do so. This has since been found to be a complete fallacy.
When should you use light years?
Light years are used to measure distance from Earth to distant stars and planets.
What is the maximum possible velocity on the earth?
Assuming that Earth is an inertial frame, and that the refraction index of air=1, the maximum possible velocity on Earth is the speed of the light, which equals 299 792 458 m/s. Albert Einstein postulated this back in early 1900's.
Is light deflects due to the gravitational force of earth?
According to Einstein's general relativity theory, light is deflected due to a gravitational pull. The light takes the shortest path in space-time, which is not the same as the shortest path in space. However, very large gravitational forces are required to get detectable deviations from the shortest path in space. When light from distant objects passes near very massive objects (such as super-massive black holes), the effect is relatively large. The deflection due to the gravitational pull of the earth is minuscule, but still detectable.
How far is the star nashira from earth?
About 229 light-years, according to Wikipedia.
What is the distance between the constilation betelgeuse and the earth?
643 ± 146 light-years, according to Wikipedia.
