The ICTP South American Institute for Fundamental Research (ICTP-SAIFR) is a new South American regional center for theoretical physics created in a collaboration of the International Centre for Theoretical Physics (ICTP) with the São Paulo State University (UNESP) and the São Paulo Research Funding Agency (FAPESP). The ICTP-SAIFR is located at the campus of the Instituto de Física Teórica (IFT-UNESP) in the city of São Paulo and activities include seminars, minicourses, schools and workshops. The center has funding for short-term and long-term visitors as well as for postdoctoral and permanent researcher

He's not 400 lbs, he's maybe 320 or so. If he was 400 lbs lean like that he'd be much larger. Look at a bodybuilder like Aaron Reed who is 6' 7" & 320 lbs, very similar physique to Tom Haviland.

This guy is my favorite physicist of his generation….i understand exactly NOTHING, but I’m still here. I am not a physicist and merely a worm with a BA…I am 48 years old, a combat veteran who missed her chance to go to medical school when I graduated with a biology degree but was forced to take a BA and not a BS as I was under a full scholarship with the.US Army and it was right after 9/11…I was ordered to immediate active duty. and today I was accepted into UC of Colo Springs Engineering school. Guess I better start working on starting my brain back up! My 19 year old son is uncertain what to think- he’s proud of me but we may end up in the same class together 😂

Hello. Is it possible at your university to create a working group involving students to work on a new❤ ❤experiment? You understand that one mind and a person are not enough? (for 119 years) By determining the constancy of speed of light, all experiments and Michelson-Morley experiments are indirect and incomplete. If the Michelson-Morley experiment was carried out on a bus or airplane and was used to determine speed. only then will this experience be direct. Therefore, Einstein does not rely on the Michelson-Morley experiment. Question. Do you have an example of such direct experience? New technologies, new research tools Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure *+reference distance* 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where - the light travels 500000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 94/94/94 cm, and the weight is 64 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions. Einstein dreamed of measuring the speed of a train, an airplane - through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven: Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,... (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

The fundamental phenomenon of dilation explains dark matter/galaxy rotation curves. Mass does that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal rotation rates. All binary stars have normal rotation rates for the same reason.

Novel Dark Matter Hypothesis Dark Matter is simply unaccounted for gravity. GR states that gravity is the consequence of the curvature of spacetime. Is it possible that the structure of spacetime itself could be warped without the presence of matter? Spacetime has been shown to react like a fabric by warping, twisting, and propagating independently of mass, and all have been proven with observations from gravitational lensing, frame dragging, and now gravitational waves! Fabrics can also be stretched, pressured, and/or heated to the point of causing a deformation and losing its elastic nature. All of these conditions were extreme during inflation, so it is plausible that the “fabric” of spacetime analog could extend having its elastic property have hit a yield point leaving pockets of inelastic spacetime geodesic that cause gravity without the presence of matter? Therefore, if gravity is strictly the consequence of the warped of spacetime, and fabrics can be permanently overstretched, then those empty warped geodesics would create gravitational wells independent of mass. My hypothesis of DM is subatomic black hole imprints of the quantum fluctuations that popped in at the moment of inflation. The CMB shows where the hot dense regions were they created the galaxies. They would have been the initial cause and location of the warping. These imprints would be clouds of quantum sized floating fixed geodesics, so they couldn’t expand or evaporate. Perhaps nothing has been detected because there is nothing to detect. GR wouldn’t require modification because DM would just be an extension of how spacetime behaves at extreme conditions. No MOND, no WIMPs, and no parallel universes, just empty spacetime deformations that produce gravitational wells to help jump start galaxy accretion processes. Zwicky may have named is Missing Mass correctly since he detected some gravity without mass present

Para calcular a estimativa de ordem de grandeza de quantas supernovas explodem por segundo no universo observável, que ela perguntou, precisamos estimar alguns valores Estima-se que haja aproximadamente 100 bilhões a 200 bilhões de galáxias no universo observável. E em média, ocorre uma supernova por cada galáxia a cada século (100 anos). Com esses dados, será até possível calcular a frequência de supernovas no universo. Quantidade de supernovas por galáxia ao ano: 1 supernova / 100 anos = 0,01 Supernova por galáxia por ano Número de supernovas por galáxia por segundos: 0.01supernovas por galáxia por ano / 365 X 24 X 60 X 60 segundos por ano = 3,17 X 10-10 supernovas por galáxia por segundo Total de supernovas por segundo no universo observável: (1011 galáxias) X (3,17 X 10-10 supernovas por galáxia por segundo) = 31,7 supernovas por segundo E se usarmos o número de 100 bilhões de galáxias: (1011 galáxias) X (3,17 X 10-10 supernovas por galáxia por segundo) = 31,7 supernovas por segundo.
