i wanna start everything from basic so just wanna know does this series cover the basic part of general relativity

Mr Vazovski 12/10/2021 - 3:35 PM

Judging by the title I thought it was an economic class

Taiyeef Sadman 12/10/2021 - 3:35 PM

What is he talking?
Is this not economics ?

Unlike my Physian he has a very good hand writing ✍.

The answer is obvious. We are in Euclidean space inside an elliptic plane. It's just light is red-shifted by elliptic gravity.

Thanks to prof. Guth and MIT for the wonderful lecture course.

Brilliant, kind of sad these came to an end.

I was researching about Higgs field and the origin of mass, I developed a research paper proposing that the mass of any particle is not its own property and hence it states that the particle is gaining its mass from external interactions. I want to know if should continue working on this research paper or my ideas and interpretations are not realistic?

Here are my views in a detail,

The standard model of particles describes the different particles based on their properties, in which Higgs boson was not yet discovered. On 4 July 2012, the Large Hadron Collider found the remaining particle “the Higgs Boson.” Following the existence of Higgs boson, the proof for the existence of Higgs field was also found. The theory of Higgs field defines mass as the result of the interaction of fundamental particles with the Higgs field. The interaction resists the fundamental particles from traveling at the speed of light. The process of encountering resistance due to Higgs field is when an object gains mass. The mass due to Higgs field is not its own mass. All the particles of the universe are massless by themselves. The mass known currently is due to Higgs field as Higgs field is present universally.

Today in the 21st century, we measure something in two forms “Mass and Weight.” Mass is the amount of matter in the substance. Whereas Weight is the effect of gravitation force on the mass of an object. We have studied that anything that has mass and occupies space is matter. According to our current understanding of particle physics, a proton is made up of 2 up quarks, and 1 down quark and these quarks are bound together by gluons. The mass when combined with 2 up quarks and 1 down quarks should be equal to the mass of the proton, as gluons are massless. But this combined mass is only 1 % of the total mass of the proton. The remaining 99% mass of the proton is due to the energy of the gluons known as quantum chromodynamics binding energy. Through the mass composition, we can conclude that the energy is equal to mass as mass is due to the energy of gluons. Because the mass is due to the quantum chromodynamics binding energy of gluons they should be considered the matter. Contrast to these mathematical calculations, the current theory of particle physics describes gluons as massless. Due to the inconsistency of data, I conclude that the definition of matter is wrong. Thus, proving the currently known mass of proton wrong according to E=Mc2 as the energy and mass are interchangeable in certain conditions but not equal. As the definition of mater was crafted when the Higgs field was not yet discovered, the definition becomes invalid after the L.H.C discovered the Higgs boson on 4 July 2012. Following the discovery of Higgs boson the Higgs field was proven to have existed, as Higgs boson is an excitation in the Higgs field. After the Higgs field was confirmed to exist, its properties hold true after that. The most important property of the Higgs field is that it gives mass to fundamental particles when interacting with the Higgs field. For example, proton’s mass was measured when the Higgs field was not yet then discovered, so the mass of proton measured was in the presence of Higgs field. This implies that the mass measured was due to the interaction with the Higgs field and not the own respective mass of the proton. This theory holds true for everything which has mass according to our current understanding of measurement of mass.
As all particles are made up of fundamental particles, so when the particle for example proton interacts with the Higgs field, the fundamental particles that make up the proton also interact as a proton is a name given to the composition of 2 up quarks and 1 down quark held together by gluons. The properties of Higgs field states that any fundamental particle when interacts with the Higgs field, it generates mass. Thus, concluding that the mass of a proton is due to Higgs field.

I'm a little confused about something. Around 9:43 prof. Guth says that d(rho)/dt = 0 because the scalar field is stuck at the false vaccum value. But rho represents the mass density of the Universe, not the energy density of the false vaccum, V(phi). I get that V(phi) is constant, but why does that implies that the mass density rho is constant as well ?

EDIT : Maybe he is ignoring the relatively small mass density from matter ? So that rho is here only the masse density of the false vaccum energy density ?

excellent lecture!!who would be better than "Guth" to explain inflationary universe, afterall he is the creator of Inflationary theory!!!

Antonio Lewis 12/10/2021 - 3:35 PM

An excellent course. Thank you to MIT OCW and to Professor Guth for sharing this with the internet!

Gavin Cawley 12/10/2021 - 3:35 PM

Excellent series of lectures, I feel I now have some idea where the science in the documentaries comes from (even though my maths was creaking a bit by lecture 14 ;o)

at@ 14:00 Professor Guth states that the change in energy equals the original energy density times the change in volume. This could only be true if the increase in volume were incremental. Otherwise, the energy density would be lower with increased volume. 

Ahan Raina 12/10/2021 - 3:35 PM

At around 5:53, Prof. Guth says that there is no way that a particle here would tunnel at the same time as a particle over there. But couldn't they be entangled?
