I discovered Einstein said the same thing about his celebrated theories of relativity that writers say about their work when he said he didn't have any feelings of personal possession of these ideas. Once they were out there, they came from somewhere else. And that's exactly the feeling when you write. You don't feel possessive about it.

Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this.

American Physicist

Brian Greene

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.

Stephen Hawking

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

Pulsars are in an ideal part of the universe to test Einstein's theory of relativity - so far, it's holding up well. They may even one day act as navigational beacons for spacecraft. I'll never tire of them; they really are the most extraordinary objects.

Douglas Sirk

And it really began with Einstein. We attended his lectures. Now the theory of relativity remained - and still remains - only a theory. It has not been proven. But it suggested a completely different picture of the physical world.

What you can show using physics, forces this universe to continue to exist. As long as you're using general relativity and quantum mechanics you are forced to conclude that God exists.

Physicist

Alan Guth

Relativity can, for instance, explain that the universe had once been clumped into a dense fireball. But it can never explain how matter actually behaved.

Albert Einstein

When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.

German Physicist

Leonard Susskind

Einstein, in the special theory of relativity, proved that different observers, in different states of motion, see different realities.

The term is strongly associated with Einstein's theories and often implies complex physics concepts.

Einsteinian Origin

It's often used in scientific contexts to discuss the fabric of space-time continuum and gravity.

Highly Scientific

Relativity implies that measurements of various quantities are relative to the velocities of the observers.

Space-Time Dynamics

Emphasizes that some beliefs and behaviors can only be understood relative to cultural context.

Contextual Values

Conveys that certain ideas or values exist only in relation to something else, not in isolation.

Interdependent Concepts

Relativity can suggest that perspectives or opinions are not universal but vary from person to person.

Subjective Perspectives

 A hundred years ago, Albert Einstein first published his theory of general relativity. In the years since then, scientists have provided a lot of evidence in support of it. But one thing predicted from this theory, black holes, still have not been directly observed. Although we have some idea as to what a black hole might look like,

How to take a picture of...

 But from having studied special relativity, the twins know it’s not that simple. First of all, the faster an object moves through space, the slower it moves through time compared to an unmoving observer. This relationship can be quantified with something called the Lorentz factor, which is defined by this equation.

Einstein's twin paradox...

 And it was his conclusions, formulated in the theory of special relativity, that opened the door into the world of time travel. Imagine a man named Jack, standing in the middle of a train carriage, traveling at a steady speed. Jack's bored and starts bouncing a ball up and down.

Is time travel possible?...

 beautiful woman and as we started talking I managed to get a conversation going with her and I talked about typical things that guys do like pie and relativity and drawing and somehow managed to get her interested in talking to me and as we talked she said what a

 if it was the speed of light that remained constant, regardless of reference frame, while both time and space were relative to the observer. It took Einstein only a few weeks to work out the details and formulate what came to be known as special relativity.

 describing the universe, right? We currently have two sets of equations that govern physics. General relativity describes the behavior of very large things, while quantum physics explains the very small. One of the biggest goals in theoretical physics

Does time exist? -...

 The universe began its cosmic life in a big bang nearly fourteen billion years ago, and has been expanding ever since. But what is it expanding into? That's a complicated question. Here's Einstein's equations of general relativity

What is the universe...

 I should've seen it before. This is so simple, so beautiful. Acceleration and gravity are the same thing. This is the idea I've been missing to complete relativity. This may just be one of the happiest thoughts of my life.

Elevator Thought...

 prevents science fiction scenarios, like using entangled particles to send messages faster than light. So relativity is safe, for now. But the quantum universe is far stranger than Einstein wanted to believe.

Einstein's brilliant...

 We used to think that the theory of the universe could be divided into two parts. First, there were the laws like Maxwell's equations and general relativity that determined the evolution of the universe,
