Loop Quantum Gravity?

I have taken a look at loop quantum gravity, and have pondered whether or not that this theory might be better than string theory because it defines the quantum composition of gravity and time. As the geometry of space-time is the manifestation of gravity which is thought to be caused by the graviton which is only hypothetical, and if it does exist is thought to be massless. In order to detect a graviton it is hypothesized that you would need the best possible detector with a mass the size of Jupiter placed in close orbit around a neutron star, and maybe under the most favorable conditions once every ten years would you be able to detect a few gravitons. Though loop quantum gravity does present a major unanswered question in physics. So let me know what you think is better loop quantum gravity or string theory?

Nuclear Fusion

This is one of my topics in nuclear physics which is an active area of research called nuclear fusion. Nuclear fusion it could supply humanity with virtually unlimited energy yet for over half a century it has eluded us. The mathematics for fusion is rather complex. I encourage viewers to do research on ITER or International Thermonuclear Experimental Reactor. This is going to be turned on in 2019 which is when the first plasma is expected. The plasma will be confined in the tokamak which is a device that magnetically confines plasma, and inside the plasma is heated to over 160 million degrees. If the ITER is successful then mankind has successfully achieved Nuclear Fusion. Using only lithium from seawater we would have enough energy to last humanity for 60 million years. Then using a more complicated fusion process using only deuterium from seawater then humanity would have enough energy to last humanity for 150 billion years. So fusion is the energy source for the future.

Quantum Field Theory

Quantum field theory is an active area of research within theoretical physics. It is provides a framework for constructing systems that involve the use of quantum mechanics. Though quantum field theory currently is completely incomprehensible because the numbers come out as infinite decimal percentages when it's supposed to explain natural phenomenon. Though some argue that nature has an infinite number of layers we now know that nature has a finite amount of layers. Some principles of quantum field theory are Newtonian gravitation, and Lagrangian Mechanics. It involes complex mathematical problems, and requires a thorough understanding of quantum mechanics to understand the basics of quantum field theory.

The Multiverse Theory

The Multiverse theory is a rather complex one as it deals with the notion of multiple universes outside of our own. Though this theory is completely contradictorial to Occam's Razor because Occam's Razor would state that the mutliverse makes to many assumptions by trying to explain our own universe with the concept of multiple universes. The multivers holds many different universes, and universes are continuously are created, and destroyed. The mutliverse contains the metaverse which holds the branes which are attached to the universe, and holds them together therefore it is the glue of the multiverse. Another part of the mutliverse theory is the concept of the xenoverse which are the alien elements completely unknown to us that exist outside the whole multiverse. Then it goes on to the hyperverse which are multiple xenoverses. Then finally it gets to the omniverse which is an infinite number of universes with an infinite number of different laws of physics. The theory is rather complex though I find it more believable than the many worlds interpretation of quantum mechanics.

Zero-Energy Universe Hypothesis

Hello there, and today I am going to talk about the Zero Energy-Universe Hypothesis which is rather strange, and complex. alright to start off the zero-energy universe hypothesis states that the total amount of energy in the universe is exactly zero. This is the case when view from the point of view of a pseudo-tensor which incorporates the energy momentum of gravity. So the positive energy in the form of matter is canceled out by the negative energy in the form of gravity. Therefore hypothetically speaking this type of universe would last forever, and would have been able to build itself from nothing. Though the nothing which science speaks of is probably the quantum vacuum because the human mind cannot comprehend absolute nothingness just like the human mind cannot comprehend infinity. Virtual particles continually pop into, and out of existence in the quantum vacuum which gives scientific credence to the notion of a whole universe coming from the quantum vacuum. Note that this hypothesis does not state where the quantum vacuum comes from so any theories on that are as of yet open to speculation. So in this hypothesis the zero-energy universe was born from quantum fluctuations described by the quantum uncertainty principle. So I would like to ask if anyone has any theories on the zero-energy universe hypothesis?

String Theory

Hello, and today I am going to be talking about String Theory which is an active area of research in particle physics. String Theory is also a potential candidate for a theory of everything (ToE) which aims to explain all natural phenomenon, and predict the outcomes of any scientific experiment. To start it off String Theory posits that the quarks, and electrons inside of an atome are not 0-dimensional objects, but that the electrons and quarks are actually composed of 1-dimensional strings. These strings oscillate causing particles to have their mass, charge, and spin. String Theory also predicts a massless state known as the graviton. This makes String Theory a quantum theory of gravity. String Theory also includes branes which are endpoints for Strings. Along with branes String Theory also includes 11 dimensions in the universe instead of the known 4. All of these theories are what makes string theory a potential candidate for a theory of everything. This is it for today on String Theory we will discuss more about it later.

Black Holes

Hello there and welcome back to topics in theoretical physics today I am going to be talking about black holes, and their structure and relation to the universe, and other celestial objects. Black holes are formed by the gravitational collapse of stars. This happens because the star exhausts all of it's energy. Then it collapses back into itself, and becomes a black hole. The gravitational pull of black holes are so strong that not even light can escape it if an object crosses the event horizon of a black hole there is no known way for it to come back it will move closer, and closer to the black hole until it is pulled in the. When objects are pulled into a black hole they undergo a process called spaghettification also called the noodle effect because the gravitational pull from the black hole is so strong that it rips, and pulls matter into noodle like strands. Then once inside the black hole the matter is compressed to infinite density in the gravitational singularity. This region is where the laws of physics breaks down, and time and space are stretched to the breaking point. No one has ever observed the gravitational singularity, and the conditions there are completely unknown, and left to speculation. Some theories about black holes, and their relation to the universe and other celestial objects is that some theories posit that the matter pulled into the black holes actually comes out in a white hole which is a hypothetical region of space where matter, and light cannot enter, but can leave which makes it the opposite of a black hole. When the matter comes here some theories posit that the matter that was compressed in the singularity to infinite density has fluctuations to where another big bang occurs, and therefore another universe created. Then another theory states that the matter pulled into a black hole does not go out of existence instead it posits that matter is composed of information, and that information is stored across the surface of the black hole instead of that information going out of existence. This concludes todays discussion on black holes.

Theoretical Physics Subjects

 

Hello my name is Rusty Burton, and I am going to be blogging about topics in theoretical physics. I will talk about such topics as string theory, and superstring theory along with quantum mechanics. I would also gladly accept any ideas or suggestions on what to blog about. I hope to delve into heavy detail the complex structure of quantum mechanics, and discuss possible candidates for a theory of everything ToE. Other fascinating topics I will delve into will be things like the multiverse, and the xenoverse. I hope this blog is intellectually stimulating, and that the viewers may gain greater knowledge in physics along with the hope that I myself will gain a great amount of knowledge from the viewers.
