What is the problem with general relativity today?

While relativity has a reputation for being intimidatingly difficult, it’s a peculiar kind of difficulty. Coming at the subject without any preparation, you hear all kinds of crazy things about time dilating and space stretching, and it seems all very recondite and baffling.

How do you solve special relativity problems?

  1. Draw a Picture. In Special Relativity problems, you relate the observations made by two observers in different reference frames measuring the same thing.
  2. Select the Relation. There are three key relations for Special Relativity.
  3. Solve the Problem.
  4. Understand the Results.

Why special relativity is a problem for the A theory?

Formally, described by the Minkowski metric: m = −dt2 + dx2 + dy2 + dz2. (Here, we assumed units with speed of light c = 1.) Mathematically, we take this geometric viewpoint: Special relativity ⇔ Minkowski geometry.

What are the flaws of theory of relativity?

Physics lore has it that Einstein later confessed that his introduction of the cosmological constant was perhaps his greatest blunder. In 1998, observations of distant supernovas showed the universe wasn’t just expanding, but the expansion was speeding up.

Is special relativity difficult?

Physics > Space and Time According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.

What math is used in special relativity?

Albert Einstein once wrote: People like us who believe in physics know that the distinction between past, present and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion. Many physicists since have shared this view, that true reality is timeless.

What was Einstein’s biggest problem?

No doubt: Einstein’s General Theory Of Relativity Was Wrong | by Gatot Soedarto | Medium. There are two kinds of Einstein’s theory of relativity. The first theory is special relativity announced in the year 1905 with the famous equation of E = mc2, that describes the propagation of matter and light at high speeds.

Is time the 4th Dimension?

At the center of a black hole, for instance, the theory’s equations no longer make sense, because they imply that matter density would become infinite. Traveling to the interior of a black hole to test general relativity would be a poor strategy, for many reasons.

Did Einstein say time is an illusion?

The drawback to Einstein’s Special Theory of Relativity, however, is that it is “special” in the respect that it only considers the effects of relativity to an observer moving at constant speed. Motion at constant speed is clearly a very special case, and in practice, bodies change their speed with time.

Who disproved the theory of relativity?

Over the past few decades well-known physicists like Kip Thorne and Stephen Hawking produced seminal work on models related to time machines. The general conclusion that has emerged from previous research, including Thorne’s and Hawking’s, is that nature forbids time loops.

Where does the theory of relativity fail?

Quantum mechanics is incompatible with general relativity because in quantum field theory, forces act locally through the exchange of well-defined quanta.

What is the biggest drawback to relativity?

General relativity has also been confirmed many times, the classic experiments being the perihelion precession of Mercury’s orbit, the deflection of light by the Sun, and the gravitational redshift of light. Other tests confirmed the equivalence principle and frame dragging.

Are time loops possible?

On paper at least, he showed that while E=mc2 always holds true for inertial mass, it doesn’t always for gravitational mass. “What this probably means is that gravitational mass is not the same as inertial,” he said. According to Einstein, gravitation is a result of a curvature in space itself.

Does quantum mechanics disprove relativity?

But how long exactly? The basic physical concepts of general relativity can be learned in as little as 30 minutes. However, for most people, building a solid understanding and learning the mathematics required for general relativity will take somewhere between 3-12 months depending on their previous knowledge.

Can the theory of relativity be proven?

No it is not possible to have space and matter without time. Space only has meaning within time. The reason why space is around us is because it takes a finite amount of time for light to reach each unique point in space from us and vice versa. Space is formed through time and only exists within the context of time.

Is E mc2 always true?

Differential geometry and in particular tensor calculus are absolutely essential prerequisites for general relativity. The obvious prerequisites are algebra, single- and multivariate calculus, coordinate geometry, vector algebra and calculus, matrices, linear algebra.

How long does it take to understand relativity?

Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared (2), or E=mc2. The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.

Is there space without time?

Albert Einstein Quotes We cannot solve our problems with the same thinking we used when we created them.

What should I learn before relativity?

One more bit of Einstein/questioning lore: From my understanding, Einstein’s theory of relativity began with an early “beautiful question” he posed, along the lines of “What if I rode a beam of light across the universe?” and then set out to answer. Anybody have more stories or insights on Einstein and questioning?

What is Einstein’s special relativity formula?

Einstein’s memory was notoriously poor. He was unable to remember dates and could not remember his own phone number. As a student, one of his teachers claimed that he had a memory like a sieve. Once when he was traveling on a train, the conductor approached to collect his ticket.

How do you explain special relativity to a child?

Did Einstein say we Cannot solve our problems?

We are actually four dimensional. We are comprised of 4 distinct but integrated parts. Three of which are related to our physical experience – the body, heart and mind. The fourth is the dimension of consciousness or spirit.

What is Einstein’s famous question?

Many are familiar with the 7th dimension as the Home of the Christ Consciousness. Here the essence of Unconditional Love combines with all the qualities we think of as God Consciousness in human form: Compassion, Empathy, Generosity, Truth, and especially Forgiveness.

What are Einstein’s weaknesses?

In the tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.

Are humans 4D?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
