Newtonian Gravity v/s Einstein's Gravity
INTRODUCTION
This is just a factual blog of basic differences between newton's theory and einstein's theory about gravitation and it will give you a basic idea of both the theories
Newton's Gravitational theory
In the 17th century, Sir Issac Newton gave his law of gravitation suggesting that gravitation is a force that holds two objects together like the earth's gravitational field holds the moon in its position, and similarly, the sun holds the planets in their respective positions as we see them and he said that the gravitational force is directly proportional to the product of the masses of the two bodies and inversely proportional to the square of the distance between them and gave the famous formula for calculating the gravitational force between two bodies, i.e., F= GMm/r^2 where G is a proportionality constant and its value is 6.67*10^(-11) Nm^2/kg^2 as given by Sir Henry Cavendish by his experiment which he performed in 1798, he used a torsion balance to determine the value of G. So, this was all about the gravitation theory given by Sir Issac Newton.
Einstein's Gravitational Theory
Now, moving on to the next gravitational force theory that is given by Sir Albert Einstein. He gave his theory 218 years after newton's theory. He said that gravitation is not a force but it is rather a curvature in the space-time fiber. This thing is explained by his famous theory of relativity which explains gravity as a distortion of spacetime caused by the presence of matter and energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime. Einstein’s theory explained a famous observation that Newtonian gravity could not: a subtlety in the orbit of the planet Mercury. And his equations implied further slight deviations from Newtonian calculations. Over the last century, general relativity’s predictions have been repeatedly verified by modern precision measurements.
CONCLUSION
So, this was all for today's topic, will continue posting content on more interesting topics like these in upcoming blogs.
Share your views about whose theory you would like to follow and which one is better...
Not sure about who is correct & If I am too Nub to give the judgement But, it should be 3 centuries instead of 2 😁😁
ReplyDeletethe exact time was actually 218 years, so, it will be considered 2 centuries only
DeleteEinstein gave the theory in 1905 and general theory in 1915 which is 20th century and Newton gave in 17th century.
DeleteYeah, you are correct, ofcourse, but the time period can be rounded off to 2 centuries only
DeleteIf we consider with centuries it will 3. But, if we consider the exact years the diff. would be 218 it would be rounded off to 200 years. And, that's the diff. between centuries and exact years, I hope U understand well @Mr. Astrophysicist
ReplyDeleteYeah, you can say so, but we will consider 2 centuries na coz we are more focused towards exact number of years, also, this thing is not something to be debated, if you have any other doubt, you can ask for that
DeleteTry to prove ur point more precisely else I will stick to my point😎
Deleteok brother/sister
DeleteI just wanna say that while writing scientific imformations, we stick to writing the exact imformation and facts,, wrong facts and imformation can lead to disagreement between members, so, that's all I want to say, if you still have any doubt, you can just google the fact
Thank you!!
ohh EXACT what a joke We had taken many values as estimation or approx and U are talking about exact Lol ! THE SPEED OF LIGHT as an example is rounded off the valur of PI and the Plank's constant
Deleteumm.... maybe you are trying to change the topic, we are talking about number of years and not constants
Deleteand also if you want to pull them in between, I must say
speed of light can be very precisely calculated, yeah of course not exactly but yeah upto some extent as it is directly given by the formula that c=1/sqrt(μ0*ε0) and putting these values, you can calculate
Yeah lemme send you proof via ss
Delete" He gave his theory two centuries " Your words in ur blog , the Silliness is that u're arguing on exact values but U urself had written in centuries which is 3 & U also agree on this in the previous message
DeleteBefore Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, flowed at its own pace, oblivious to the clocks that measured it. But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted, generating sound and fury, signifying gravity.
DeleteFAKE
DeleteOk, I have changed the thing, is it fine now?
DeleteYa, now it's fine now it is exact and not the centuries🙂🙂
