**The answer is a clear NO**. The base of all physics are phenomena. If two theories contradict each other there will be an experiment to resolve this contradiction i.e. a phenomenon that falsifies one of the theories.

## What does consistent mean in physics?

The semantic definition states that **a theory is consistent if it has a model**, i.e., there exists an interpretation under which all formulas in the theory are true.

## Why quantum mechanics is an inconsistent theory?

*Now you see current quantum mechanics strictly speaking is an inconsistent theory that's rather brutal way of saying what einstein and schrodinger. And even dirac.*

## How do you know if its consistent or inconsistent?

To see if the pair of linear equations is consistent or inconsistent, we try to gain values for x and y. **If both x and y have the same value, the system is consistent**. The system becomes inconsistent when there are no x and y values that satisfy both equations.

## Is no solution inconsistent?

**If a system has no solution, it is said to be inconsistent** . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

## Is quantum physics consistent?

**The agents’ conclusions, although all derived within quantum theory, are thus inconsistent**. This indicates that quantum theory cannot be extrapolated to complex systems, at least not in a straightforward manner.

## Who proved black holes exist?

‘” **Roger Penrose** (left) proved black holes are real objects. Andrea Ghez (center) and Reinhard Genzel (right) showed that one weighing 4 million times as much as the Sun lurks in the heart of our galaxy. Since Penrose’s advances, astronomers have found a wealth of evidence for black holes.

## What did Penrose win the Nobel Prize for?

black hole formation

The Nobel Prize in Physics 2020 was divided, one half awarded to Roger Penrose “for **the discovery that black hole formation is a robust prediction of the general theory of relativity**“, the other half jointly to Reinhard Genzel and Andrea Ghez “for the discovery of a supermassive compact object at the centre of our …

## What is Penrose theory?

The Penrose interpretation is **a speculation by Roger Penrose about the relationship between quantum mechanics and general relativity**. Penrose proposes that a quantum state remains in superposition until the difference of space-time curvature attains a significant level.

## Why is string theory wrong?

The internal problems of the theory are even more serious after another decade of research. These include the **complexity, ugliness and lack of explanatory power of models designed to connect string theory with known phenomena, as well as the continuing failure to come up with a consistent formulation of the theory**.

## What did Roger Penrose and Stephen Hawking do?

Penrose **shared the Wolf Prize for physics with Stephen Hawking for this work on the Penrose-Hawking singularity theorems**. Penrose is also known as the founding father of quantum gravity through his work on twistor theory, which addresses the geometry of space-time.

## What is cyclic universe theory?

The cyclic universe theory is **a model of cosmic evolution according to which the universe undergoes endless cycles of expansion and cooling, each beginning with a “big bang” and ending in a “big crunch”**.

## Is an oscillating universe possible?

At the end of the collapse phase, with the universe packed into a small volume of great density, **it is possible that a ‘bounce’ would occur**. The universe would thus oscillate between Big Bang and ‘Big Crunch’ episodes, and so be infinite in age.

## What is the black hole theory?

The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by **Einstein’s theory of general relativity**, which showed that when a massive star dies, it leaves behind a small, dense remnant core.

## Is time linear or cyclical?

2. **Time is cyclical**. Time is marked by repetition — the sun rises and sets, seasons change, and living things go through the biological cycle of birth, life, death.

## Why did Einstein say time is an illusion?

As For Einstein

As we saw from Einstein’s quote, he believed that time is an illusion, that **both the future and the past are unchangeable, and will play out exactly the way they were meant to**.

## Is time a illusion?

According to theoretical physicist Carlo Rovelli, **time is an illusion**: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock.

## Is time an illusion Einstein?

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.

## Does the past still exist?

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.**

## Does the present exist?

In fact, mathematically, we define the now as a single point in time. This point is an abstraction and, believe it or not, it has no duration. Ergo, mathematically, the present is a point in time with no duration: **the present doesn’t exist**!

## Is time finite or infinite?

As a universe, a vast collection of animate and inanimate objects, **time is infinite**. Even if there was a beginning, and there might be a big bang end, it won’t really be an end. The energy left behind will become something else; the end will be a beginning.

## Did Einstein think the universe was infinite?

In contrast to this model, **Albert Einstein proposed a temporally infinite but spatially finite model** as his preferred cosmology during 1917, in his paper Cosmological Considerations in the General Theory of Relativity.

## Are stars infinite?

Answer A : **No, the number of stars cannot be infinite**.

This number may be very big, but it has a definite value. The same goes for stars. Each of all the stars at the instant t has her own size, and we can give her a name.

## Is a flat universe infinite?

Because space isn’t curved they will never meet or drift away from each other. **A flat universe could be infinite**: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.

## Does space have a bottom?

**The universe has a bottom**. That bottom extends infinitely outward and has an infinite sky above it, with an infinite number of stars and galaxies. The bottom is remarkably terrestrial, with gravity, mountains, lakes, forests, and sunshine, each of which deserves additional discussion.

## Is time Travelling possible?

**Yes, time travel is indeed a real thing**. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
