What is Quantum Gravity? | COSMOS in a minute #25

Quantum gravity is the hardest problem in physics. It's the attempt to unify the two pillars of modern physics: quantum mechanics and general relativity. It's the study of how gravity works at the quantum level, where the laws of physics are very different from what we experience in everyday life. One of the biggest challenges in quantum gravity is that gravity is the weakest force in nature. It's so weak that it's impossible to study for particles in the lab. We can only see its effects on very large objects, like planets and stars. Scientists have been working on quantum gravity for decades, but they haven't been able to come up with a complete theory. So it remains one of the biggest unsolved mysteries in physics, one that scientists are determined to solve.

I think this is because gravity isn't a force, it's just the curvature of spacetime (theory of relativity). If you fall in the vacuum, there ins't any force that acts on you. For example the astronauts on the ISS are just weightless, because the fall around the earth.

[@Bluzigo]

A quick correction: the astronauts on the ISS DEFINITELY experience gravity! The reason they are able to stay above the surface of the earth and “float” around is because they are in orbit. This means they are still falling towards the earth (astronauts experience about 90% the force of gravity we feel on earth) but they are moving SIDEWAYS so fast, that they move away from the curvature of the earth at the same time. Basically, if there was absolutely no gravity in a vacuum, there would be no need to travel horizontally. This is why rocket ships spend a majority of their fuel accelerating sideways, they need to go fast enough to go into orbit, or “fall forever”!

[@createfox]

@@Bluzigo Yes, they experience gravity, but not as a force, there is no force acting on them but they still orbit the earth, because of gravity. This has to mean that gravity isn't a force, because they are weightless and no force is acting on them, but there is still gravity "acting" on them (I think). Correct me if I misunderstood something.

[@Bluzigo]

@@createfox I totally see where you’re coming from! You’re not entirely wrong, but technically gravity is still a force acting on them. When in orbit, astronauts are essentially in free-fall. Since there is no “ground” that will stop them from falling (because orbit) they will basically fall forever! It’s similar to jumping on a trampoline. Whenever you are midair, it feels like you’re falling. You could even bring something on the trampoline with you, like a ball, and let go the moment you jump into the air. The ball will fall at the same speed as you, so it looks like it floats! Edit: also, since the earth is a HUGE sphere and curves away, you can imagine how fast you would need to move sideways to fall the same amount the earth curves away from you (for the ISS, over 4 miles per second!)

The problem of modern physics is they're trying to explain everything with particle physics and the physics is being cornered more and more to the dead end. The interaction between mass and space must be explained with quantum mechanics. But that doesn't mean gravity is the QM phenomena. That's because gravity is not a force. Gravity is just a joint effect of the expansion of the Universe and the curvature of spacetime. Details are given below. Alternative Explanation of Dark Matter and Dark Energy - Newly proposed model of Universe can explain both of Dark Matter and Dark Energy Einstein’s theory of General Relativity states that spacetime is curved by the presence of mass. This curvature influences the motion other objects with mass and gives rise to gravitation. Thus, gravity is a result of geometric features in spacetime. However, we also observe gravitational effects - curvature of spacetime - in areas without any detectable mass. This has given rise to the concept of dark matter, which is matter that does not interact in any detectable way with normal matter, except through gravity. So, there is some large quantity of dark matter scattered throughout the universe, which curves spacetime and causes gravitational effects just like normal matter, but we cannot see or detect it with any known method. An alternative theory to the identity of dark matter is proposed - it is not matter at all, but rather an intrinsic curvature of spacetime. In other words, spacetime is not naturally flat. Even in the absence of matter, we observe some inherent curvature of spacetime. So, the question is now - why is spacetime naturally curved? Why is it not flat in the absence of mass? The universe is 4-dimensional, with 3 spatial dimensions and one dimension in time. Rather than consider time as a linear dimension, we can consider it as a radial one. Therefore, rather than describing the universe with a Cartesian coordinate system, we describe it with a 4-dimensional spherical coordinate system - 3 angular coordinates, φ1, φ2, φ3, and one radial coordinate in time, t. We live on the 3-dimensional surface of a 4-dimensional bubble which is expanding radially in time. Thus, the Big Bang represents t=0, the beginning of time. The crucial point is that the expansion of the universe is not homogeneous in all directions. The expansion rate at one point on the bubble’s surface may differ slightly from another point near it. The universe is only roughly spherical in 4 dimensions, the same way that the Earth is only roughly spherical in 3 dimensions. The same way we observe local mountains and valleys on the surface of Earth, we observe local “mountains” and “valleys” on the surface of the universe bubble. The inhomogeneity of the expansion of the universe has given rise to natural curvature of spacetime. This natural curvature causes the phenomenon of “dark matter”. “Valleys” in spacetime pull matter in, similarly to the warping of spacetime of massive objects. So “dark matter” is really “valleys” in spacetime that are expanding slower than the regions surrounding it. These valleys tend to pull matter in and create planets, stars, and galaxies - regions of space with higher-than-average densities of mass. Conversely, “mountains” in spacetime will repel matter away, an “anti-gravitational” effect, which gives rise to cosmic voids in space where we observe no matter. Each point on the surface of the universe bubble traces out a time arrow in 4-dimensional space, perpendicular to the surface. These time arrows are not parallel to each other since the universe is not flat. This causes points to have nonzero relative velocity away from each other. It is generally accepted that the universe is expanding faster than observable energy can explain, and this is expansion is believe to be still accelerating. The “missing” energy required to explain these observations has given rise to the theory of dark energy. The time dilation caused by non-parallel time arrows can be proposed as an explanation for dark energy. Alternatively, dark energy is real energy coming from potential energy gradients caused by non-parallel time arrows. As a sanity check, we can calculate the expansion rate of the universe based on the universe bubble model. Since the radius of the universe bubble is expanding at the speed of light in the time direction, it increases at 1 light second per second. Therefore, the “circumference” of the 3-dimensional surface increases by 2π light seconds per second, or about 1.88*10^6 km/s. This expansion is distributed equally across the 3-dimensional surface, so the actual observed expansion rate is proportional to the distance from the observer. At present, the age of the universe is estimated to be 13.8 billion years, so the radius of the universe bubble is 13.8 billion light years, or about 4233 megaparsecs (3.26 million light years to 1 Mpc). Thus, we can calculate the expansion rate of the universe, per megaparsec from the observer, as: Expansion rate = ((d(circumference))/dt)/radiusofuniverse=(1.88*〖10〗^6 km⁄s)/(2π*4233Mpc)=(1.88*〖10〗^6 km⁄s)/26598Mpc=70.82(km⁄s)/Mpc The popularly accepted empirical expansion rate is 73.5 + 2.5 km/s/Mpc, so our calculated value is close. There may be some additional source of expansion (or observed red shift) to make up for the discrepancy. For example, if two adjacent points have some gravitational gradient due to non-parallel time arrows, then light passing through these points will be red-shifted. - Cited from www.academia.edu/82481487/Title_Alternative_Explanation_of_Dark_Matter_and_Dark_Energy

Quantum gravity is a theoretical framework that seeks to reconcile the principles of quantum mechanics, which govern the behavior of particles on very small scales, with the theory of general relativity, which describes gravity on cosmological scales. The challenge arises because traditional quantum mechanics and general relativity are formulated in ways that appear incompatible when applied to extremely strong gravitational fields, such as those near the center of black holes or during the early moments of the universe. Here are key aspects of quantum gravity: 1. **Quantum Mechanics and General Relativity Conflict:** - Quantum mechanics successfully describes the behavior of particles at the subatomic scale. - General relativity successfully describes gravity and the curvature of spacetime caused by mass and energy. 2. **Quantum Gravity Unification Attempts:** - Physicists are working on theories that aim to unify quantum mechanics and general relativity into a single, consistent framework. - String theory and loop quantum gravity are among the prominent approaches to quantum gravity. 3. **String Theory:** - In string theory, fundamental particles are not point-like but rather tiny, vibrating strings. - The theory incorporates gravity naturally and attempts to provide a unified description of all fundamental forces. 4. **Loop Quantum Gravity:** - Loop quantum gravity views spacetime as a network of interconnected loops. - Quantization is applied to the geometry of space, leading to discrete structures at the smallest scales. 5. **Challenges and Open Questions:** - Developing a complete and experimentally testable quantum theory of gravity remains a significant challenge. - The extreme conditions where quantum effects become crucial (e.g., near the singularity of a black hole) are difficult to observe and test. 6. **Cosmological Implications:** - Quantum gravity is essential for understanding the behavior of the universe at the earliest moments, such as during the Planck epoch. In summary, quantum gravity aims to extend our understanding of the fundamental forces by addressing the challenges that arise when combining quantum mechanics and general relativity, ultimately providing a unified description of

To create a standard linear regression model equation, you need to have the following components: 1. **Dependent Variable (Y):** This is the variable you are trying to predict. 2. **Independent Variable(s) (X):** These are the variables used to predict the dependent variable. 3. **Coefficients (β):** These are the values representing the slopes of the independent variables. 4. **Intercept (β₀):** This is the value of Y when all independent variables are set to zero. The equation for a simple linear regression with one independent variable would be: \[ Y = β₀ + β₁X + ε \] Where: - \( Y \) is the dependent variable. - \( X \) is the independent variable. - \( β₀ \) is the intercept. - \( β₁ \) is the coefficient for the independent variable. - \( ε \) is the error term. For multiple linear regression with more than one independent variable, the equation would be: \[ Y = β₀ + β₁X₁ + β₂X₂ + ... + βₖXₖ + ε \] Where: - \( Y \) is the dependent variable. - \( X₁, X₂, ..., Xₖ \) are the independent variables. - \( β₀ \) is the intercept. - \( β₁, β₂, ..., βₖ \) are the coefficients for the independent variables. - \( ε \) is the error term. You can find the values of the coefficients and intercept by fitting your data to the linear regression model using statistical software or programming languages like Python with libraries such as scikit-learn or statsmodels.

The Higgs Field is forced into each body, interacting (colliding) with the quantum fields of the stellar objects, pushing them toward the center of mass (but the mass of objects resist each other, giving the "gravity" appearance). Only light waves seem not to collide with the Higgs Field, but it does curve as it passes through the collapsing density of the Higgs Field around massive objects. No gravity. No curved space/time.

Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics. It deals with environments in which neither gravitational nor quantum effects can be ignored,[1] such as in the vicinity of black holes or similar compact astrophysical objects, such as neutron stars[2][3] as well as in the early stages of the universe moments after the Big Bang.[4] Three of the four fundamental forces of nature are described within the framework of quantum mechanics and quantum field theory: the electromagnetic interaction, the strong force, and the weak force; this leaves gravity as the only interaction that has not been fully accommodated. The current understanding of gravity is based on Albert Einstein's general theory of relativity, which incorporates his theory of special relativity and deeply modifies the understanding of concepts like time and space. Although general relativity is highly regarded for its elegance and accuracy it has limitations: the gravitational singularities inside of black holes, the ad hoc postulation of dark matter, as well as dark energy and its relation to the cosmological constant are among the current unsolved mysteries regarding gravity;[5] all of which signal the collapse of the general theory of relativity at different scales and highlight the need for a gravitational theory that goes into the quantum realm. At distances close to the Planck length, like those near the center of the black hole, quantum fluctuations of spacetime are expected to play an important role.[6] The breakdown of general relativity at galactic and cosmological scales also points out the necessity for a more robust theory. Finally the discrepancies between the predicted value for the vacuum energy and the observed values (which, depending on the considerations, can be of 60 or 120 orders of magnitude)[7] highlight the necessity for a quantum theory of gravity. The field of quantum gravity is actively developing, and theorists are exploring a variety of approaches to the problem of quantum gravity, the most popular being M-theory and loop quantum gravity.[8] All of these approaches aim to describe the quantum behavior of the gravitational field, which does not necessarily include unifying all fundamental interactions into a single mathematical framework. However, many approaches to quantum gravity, such as string theory, try to develop a framework that describes all fundamental forces. Such a theory is often referred to as a theory of everything. Some of the approaches, such as loop quantum gravity, make no such attempt; instead, they make an effort to quantize the gravitational field while it is kept separate from the other forces. Other lesser-known but no less important theories include Causal dynamical triangulation, Noncommutative geometry, and Twistor theory.[9] One of the difficulties of formulating a quantum gravity theory is that direct observation of quantum gravitational effects is thought to only appear at length scales near the Planck scale, around 10−35 meters, a scale far smaller, and hence only accessible with far higher energies, than those currently available in high energy particle accelerators. Therefore, physicists lack experimental data which could distinguish between the competing theories which have been proposed.[n.b. 1][n.b. 2] Thought experiment approaches have been suggested as a testing tool for quantum gravity theories.[10][11] In the field of quantum gravity there are several open questions - e.g., it is not known how spin of elementary particles sources gravity, and thought experiments could provide a pathway to explore possible resolutions to these questions,[12] even in the absence of lab experiments or physical observations. In the early 21st century, new experiment designs and technologies have arisen which suggest that indirect approaches to testing quantum gravity may be feasible over the next few decades.[13][14][15][16] This field of study is called phenomenological quantum gravity.

All mass are waveforms. Those waves don't disappear at some arbitrary distance from their source. The Earth's gravitational field (for instance) is the total of all the waves of all its mass. That is like the Earth is surrounded by concentric spheres. That is why space curves around mass. The wavelength (how close those concentric spheres are to each other) is given by de Broglie's equation: The wavelength of mass is equal to Planck's Constant divided by it's momentum. Time dilation is the inverse relation between Graviton density and the rate of physical processes. There must be gravitons because the inverse square law of gravitational strength sayas so.

Something is not adding up. This example represents space as a 2 dimensional sheet. But we live in 3dimensional space so if you drop a ball into jell it would just sink to the bottom and create space curviture around itself.
