General and Special Relativity
Relativity is the theory stating that all measurements depend on the relative motions of the observer and the observed. The theories of general and specific relativity were both proposed by Albert Einstein.

How did relativity change the world?
Relativity, proposed by Albert Einstein, revolutionized our understanding of space, time, and gravity. It led to new developments in physics, technology, and communication, such as GPS systems and nuclear energy. Relativity also inspired new ways of thinking about the universe and our place within it.
Where did Albert Einstein create the general theory of relativity?
The development of the General Theory of Relativity was not just a single effort. It was the combination of several things Einstein worked on. Einstein published his first paper on Special Relativity while working in the Swiss patent office. It may be assumed that he created much the theory while working there although he undoubtedly spent a great deal of time outside of work pondering on it and probably had been thinking of parts of it even before he took the patent examiner job.
His work on General Relativity occured between 1907 and 1915 so he started it while working in Bern, continued his work while working as a lecturer at the University of Bern in 1908, then physics docent at the University of Zurich in 1909, then full professor at Karl-Ferdinand University in Prague in 1911, then he returned to Germany after being appointed director of the Kaiser Wilhelm Institute for Physics and a professor at the Humboldt University of Berlin.
It can therefore be said that he created the General Theory of Relativity step by step in Bern, Zurich, Prauge, and Berlin.

Is there a constant for time at the center of mass of a planetoid and blackhole formation threshold?
Maksim A. Burakhovich absolute time: since time is relative where on Earth time goes slower than in space since gravitational field slows time down, i guess we could designate absolute time as time at the center of mass of the heaviest object in the Universe that's not a black hole or where the difference in mass between that object and the litest black hole in terms of mass in the Universe is infinitesimal.
What causes gravity according to the Einstein's theory of general relativity?
Gravity, according to Einstein, is caused by matter and energy which bends spacetime. This deformed spacetime then gives the appearance of gravity even though objects are traveling in straight lines in a curved space.
Time dilation is tied into Einstein's theories of Relativity. It is the the difference of elapsed time as measured by two different observers. This means that Time Dilation is basically how two people perceive the passing of time-based on the conditions they are traveling in. These "differences" in time are mosty tied to An increase in gravity and fast travel. For speed, traveling at the speed of light (hypothetical) would cause your time to slow down because you are moving at the same speed as the light around you. This causes the time for you to slow down relative to an observer not traveling at that speed. In theory, if they looked at you in a ship you are traveling in, they would see you moving in slow motion. FAST=SLOW. For gravity, the closer you are to a high source of gravity such as a black hole, the slower your time moves. The reasons for this are hard to explain and are past my abilities to put into words (I'm 17 and never taken a physics class, I just have a passion for this sort of topic). But in general, Time dialation revolves around Einsteins theories of special relativity and is caused by the your interation with light in the case of time dialation during speed, and your interaction with bending of spacetime in the case of time dialation with gravity. Now these "time changes" take extreme velocity and gravity change to cause any real difference so it does not effect everyday life on earth. Sorry in simple terms, time dilation is the changing of the a persons "time" based off the a relative observer. The movie "Interstellar" has great examples of time Dilation. Hope this helps.
Who is the scientist who translated Einstein's general theory of relativity from German to English?
Satyendra Nath Bose
What job did Einstein when he developed the Theory of Relativity?
"Scentist oviuosly" <---- I just had to keep this answer, because this person is an absolute idiot.
Einstein was a patent clerk when he developed the theory of special relativity.
When is cousins day celebrated?
There is no such day as cousins day.
-------------
I have heard it is July 24th.
Why is albert Einstein's math important?
Einsteins math was deplorable he barely staggered through it with help from many of his peers. His derived equations are the foundation of our current knowledge of the universe and the basis for modern computing theory.
How did Albert Einstein's theory of relativity make a difference?
Development of GPS Technology (Satellites at high altitude moving at high velocities)
Atomic Clocks (adjust for lost nanoseconds)
Radio telescopes
What are the advantages and disadvantages of ppt?
ADVANTAGES:
The points can be easily summarised.
Quickly summarised.
easily illustrated.
DISADVANTAGE
Easily not understandable.
The points are not sufficient.
Data insufficiency.
What is the difference between Galilean relativity and Einsteinian relativity?
Galilean relativity asserts that the passage of time is the same for all observers. Einsteinian relativity does not claim universal time for all observers. Instead, it asserts that the speed of light and the fundamental laws of physics are the same for all observers.
What are the first and second postulates of special relativity?
First Postulate:
All the laws of nature are the same in all uniformly moving frames of reference.
Second Postulate:
The speed of light in empty space will always have the same value regardless of the motion of the source or motion of the observer.
Is gravity a wave or a particle?
Neither. It's a force. A force of space that acts similar the the pressure of water exerted on an object when in deep waters. Space is the ultimate of deep waters.
What did Einstein mean when he said gravity warps space?
He meant that the gravitational pull of a mass is just the curvature of spacetime caused by a mass. You can think of spacetime as a blanket pulled tight on all corners. If you place a large object in the center, things on the outside of the blanket will go towards the larger object in the center.
Why did Albert Ainstein get a compass?
I hope I am not missing a joke.
He needed it to navigate his sailing boat.
Can people pull themselves up by their bootstraps?
No they cannot. This is because while you are applying an upward force on your boots, you apply an equal downward force on your back (and by extension also on your feet and boots). Thus everything cancels each other out.
This is a direct consequence of the law of conservation of momentum; if you could pull yourself up by your bootstraps you could generate momentum from nothing.

What predictions of general relativity have been verified if any?
General relativity has been verified through several key predictions. Notably, the bending of light around massive objects, as observed during solar eclipses, confirmed the theory. Additionally, the detection of gravitational waves in 2015 provided strong evidence for the existence of these ripples in spacetime, predicted by Einstein. The precise measurements of time dilation effects, such as those seen in GPS satellite technology, further validate the theory's predictions.
To determine the value of g acceleration due to gravity by means of an angular pendulum?
The period (time) of one swing of a pendulum is
(2 pi) times the square root of (pendulum length / acceleration of gravity). There are three variables in this formula ... the length of the pendulum, the period of its
swing, and the acceleration of gravity. If you know any two of them, you can calculate the
third one. You want to use this method to measure gravity ? Fine ! Massage the formula
around to this form Acceleration of gravity = (length of the pendulum) times (2 pi/period)2 then start measuring and swinging.
The more accurately you can measure the length of your pendulum, from the pivot
to the center of mass of everything that swings, and the period of its swing, and the
more completely you can isolate everything from outside influences, like air currents,
the more accurately you can calculate the acceleration of gravity, in the exact place where
you run the experiment.
Why do some people not like sports?
some people just arent into that. in my opinion most people feel intimidated by all the athletic people at school oron tv. it makes them feel week.
