According to Einstein, What happens when starlight is deflected by the Sun?

Question

plz describe

Answer 1

Then solar masses acts as gravitational lenses.

These lenses have now become a standard tool of astronomy. They allow astronomers to infer the masses of cosmic objects, and the structure and size scale of the universe (with some caveats). Through their magnifying effect, gravitational lenses have also been used to observe the properties of very distant galaxies and quasars, as well as to search for planets around distant stars.

Answer 2

You misquote the equivalence principle.

The strong version of the equivalance principle is:

"The results of any local experiment, gravitational or not, in an inertial frame of reference are independent of where and when in the universe it is conducted."

This does not seem unreasonable as you suggest, and is easy to test. Of course you can look at deflection of starlight (and it is simple to allow for atmospheric distortion), but you can also conduct local experiments such as those using the Mossbauer effect that demonstrate gravitational red shift.

In fact, gravitational red shift is a good example of showing how a consequence of thinking as you do causes you to lose another cherished principle of physics - conservation of energy.

If gravity's effect was not to create an accelerating frame, then you could violate energy conservation. Here is the thought experiment. You construct a machine that can convert matter to light (impractical, but does not violate anything). You shine the light up a tall tower. At the top of the tower - height h - you use a machine to turn it back to matter. Then you drop it.

Now if you had sent the matter up the tower it would have cost mgh in energy. If the same is not true of the light, then when you drop the mass you will get a net gain of mgh of energy. Voila - perpetual motion. Except for the principle of equivalence.

Answer 3

According to Einstein, a mass, such as the sun, actually bends space (and time) around it. Normally space should be flat, and light beams should go straight.

But when space itself is curved, light beams bend a little.

This is how Einstein explained gravity. Instead of being a "force" that pull things, massive objects instead curve or bend space. The earth goes around the sun not becuase of the force of gravity, but because the earth is travelling, by iniertia, in curved space.

It turns out that Einstein's explanation of gravity work a little better than Newtons.

Answer 4

Nice nonsense, joe. But thanks for playing.

OK. What really happens is that to an observer it looks like as if the light gets deflected and delayed. What actually happens is that the light maps out the curvature of space around a large mass.

None of this requires any "Gedankenexperiments". It can all be measured in reality and has been:

Answer 5

starlight gets deflected by the sun???!
never knew that,
meby the photons being released by the run intersepts the ones from the sars and knocks them off course since the sun's photons would have more energy due to the less distance travel through space.
thats just a guess though
btw, u cant blame it on gravity,
as for what happens after it's deftlected by the sun, my guess is that it just continues on it's journey to the dpths of spaces until it intersept somthing.
the suns gravity is not even close to bend the light slightly, even if it were, it would suck it in, not deflect it.
u'll need a black hole to do that much work.
As for what happens after the defecltion, i hav no idea,
it probably jus continues on it's new path

Answer 6

you probably did a especially good activity describing it your self. area bends as a results of mass an identical way a rubber sheet bends once you yet a weight on it, albeit in 3 dimensions fairly than 2. An merchandise's course or a beam of sunshine's course around a action picture star is incredibly right this moment... it relatively is purely that "right this moment" around that action picture star is incredibly bent. that's what the bending of area is all approximately. The equations you learn many times physics approximately count being fascinated in an excellent merchandise are incredibly deceptive. Mass isn't fascinated in mass otherwise mild that's massless would not be tormented via super gadgets like stars. because of the fact of this Einstein formulated his concept of popular relativity. Gravity isn't approximately allure, its approximately bending area. one thank you to think of roughly it relatively is to play around with the common definition of acceleration on the earth. You status on the floor or shifting at a consistent velocity interior of a automobile is oftentimes an occasion of you no longer accelerating, even though that may no longer authentic. you're accelerating, the floor is pushing you up. you're accelerating upward. it relatively is purely like in case you have been in a spaceship accelerating in any course at 9.8m/s^2. it relatively is purely once you're in loose fall which you're no longer accelerating. So once you drop an apple, that apple isn't accelerating downward, you're accelerating upward. PLEASE be conscious: do no longer take that final occasion to the financial corporation. i'm no longer an authority many times relativity, i've got purely studied slightly of the plenty much less confusing concept of specific relativity which does no longer have plenty to do with this. the point of the occasion is purely to hit domicile the version between captivating forces like that of electromagnetism and the non captivating stress of gravity.

Answer 7

According to Al Gore (the smartest man alive that didn't win his own state in 2000), fossil fuels from cars, and people farting, blocks this important starlight from reaching our planet. The sun is all deflected which causes global cooling and a new coming ice age, which is what all the nutzo-scientists told us in the 70s.

So between the farting, cooling, fossil gases, polluting oil companies who avoid paying taxes and ruin our environment, people using hair spray with CFC, and Al Gore burning hundreds of tons of jet fuel to tell everyone to save the planet by not using..........what's the question again?

Answer 8

According to Einstein,a massive object will have enormous gravity and it will attract light also.So, it would get deflected by the sun.

The photons will be affected by the gravity

Answer 9

Albert Einstein used his famous thought experiment to justify his "Principle of Eqivalence" postulate that asserts; Inertia (acceleration) and Gravity are equivalent. (Although he used a room size chest and a rope I am substituting a rocket instead).

"An astronaut in an accelerating rocket will feel the same effect as if he were standing on earth." This is true but it is not because gravity and inertia are equivalent, it because these two conditions produce the same effect, WEIGHT. Acceleration does not create gravity, it creates weight, under certain conditions.

Inertia is the law of nature that requires a force be exerted on a body to accelerate the body, relative to other bodies (momentum), or to rise it to a higher space energy level, relative to absolute space (inertial mass).

Gravity, a "primary force", is just one the laws of nature that fulfills this requirement.

Actually, in both cases the accelerating rocket and the room resting on the ground, weight, not gravity, is created! The weight created in the accelerating rocket,(or Einstein's chest being pulled by a rope) is just as real as weight created on the surface of the Earth. The effect of "weight" is created in both cases because a Secondary Force is being exerted on the body, altering the body's primary inertial or gravitational acceleration, not because Gravity and Inertia are equivalent.

Weight is created simply because:

1. Inertia requires a force be exerted a body to accelerate the body.

2. The unique manner that a Secondary (Ordinary) Force exerts its force on a body. Secondary force exerts its force in succession, one body pushes against the next body which pushes against the next etc. etc.. A molecule pushes against the next molecule, an atom pushes against the next atom (even though, at this level they may not actually touching each other), the floor of a rocket pushes against the feet of an astronaut which pushes against his/her ankles which push against his/her legs etc. etc. It does not matter whether you are standing on the surface of earth or if you are accelerating in a rocket. The effect is the same - weight is created.

Gravity, a Primary Force, exerts its force on all the atoms of a body simultaneously, not in succession. That is the big difference! A body accelerating under Gravity's influence alone is weightless. Only when a Secondary Force alters the body's gravitational acceleration, in some manner, is the effect of weight created (such as preventing a body "resting" on the surface of earth to accelerate toward the center of earth). All bodies "resting" on earth's surface are actually in a state of restrained acceleration.

In both cases of Einstein's thought experiment (Accelerating room and the room "resting" on the ground) a Secondary Force is creating the effect of weight. When a Primary Force such as Gravity is exerted on a body alone, (falling body) the body accelerates but the body is weightless!

Gravity is exerting exactly the same amount of force on each atomic particle of the body, simultaneously. This causes the feeling of weightlessness. This lack of weight sensation fooled Einstein into thinking that no force was being exerted on the body - that gravity is not a force! He said that falling bodies simply follow geodesic lines of curved space.

Actually the falling body is completely under the influence of gravitational force. It is being accelerated by gravity alone and therefore no weight sensation is created. Weight itself is not a force, it is the unique effect created - when a Secondary Force is exerted against a body and can be used as an accurate measurement (weight) to indicate the amount of Secondary Force that is being exerted. On Earth, weight is the measure of Secondary Force required to prevent a body from accelerating 32.2 ft./sec.2 toward the center of Earth.

Weight is created only when a Secondary Force is exerted against a body, thereby altering the body's original inertial acceleration caused by a Primary Force. It could be Gravity or another Primary Force such as those that arise from the chemical reactions which produce the gases that propel a rocket or the electromagnetic force of the elevator's motors, it makes no difference.

The important thing is that a Secondary Force must be exerted to STOP OR ALTER the body's acceleration for the effect of weight to be created. If a body is "resting" on the surface of the Earth, the surface prevents (stops) it from continuing its fall toward the center of the Earth.

It is Secondary Force that creates the effect of weight in both cases. Therefore, Einstein's postulate, "The Principle of Equivalence", has not been proven by his thought experiment. The idea that a light beam will be influenced by Gravity being exerted on it, also has not been proven.

The star's light beam that was supposedly deflected by the Sun’s gravity to add credibility to Einstein’s theory, was probably optically deflected by the Sun’s atmosphere as it passed through its extended corona.
