Public Lecture: Dark Energy

Welcome to 'Discover Our Universe' at KIPAC! This is a series of free, public lectures in astrophysics. The lectures are designed with the general public in mind, and are fun, easy to understand, and engaging.
Dark Energy was initially suggested as an explanation for the accelerated expansion of the cosmos, yet its true nature remains unknown. In this lecture, Dr. Sandy Yuan will guide us to explore this mysterious aspect of the Universe alongside the human stories of discovery. He will begin by revisiting the discovery of the expanding Universe and the rise of the Big Bang and the cosmic inflation. Dr. Yuan will then discuss the motivation for dark energy and its current state of study, including emerging inconsistencies in our measurement of the expansion rate of the Universe from different probes. Finally, we will look ahead to future experiments and theoretical considerations that can help refine our understanding of the Universe.

The MTS equation relates Dark Energy to Dark Matter, as well as Black Holes, the Standard Model and so on.

Great video! Thank you! I Love Dark Energy! If you are interested, see CIG Theory and the comments section. Dark Energy is the far end of the MTS equation. The wavelength is longer than Dark Matter. The near end of the MTS equation is pure matter or Black Holes. Try learning CIG Theory today - no math and easy to comprehend. Enjoy knowledge - be friendly.

Could your data confirm that the stellar entities that are releasing the most ENERGY are also the entities that have the greatest RED SHIFT? Normalized one to the other to an even spatial background field (i.e. isolated and corrected to remove RED SHIFT expansions from other foreground and background "OTHER RED SHIFTS", such that one is only seeing the Red Shift of that specific stellar entity alone. And that the isolated RED SHIFT correlates to the greatest energy release (released from the entity into Space, not contained and not released) (actually not into Space but a creation of Matter to Space) is proportional to the greatest expansion. And this correlates to an expansion (creation of Space from Matter) ENERGY to SPACE based on ENERGY. And does this align in any way with the CUPI as calculated in the book "I Have Become Space" ? In other words, please use your data to confirm CIG Theory. It's right there. CIG Theory is the fundamental explanation for the data you are seeing. Please investigate. In CIG Theory, E=MC2 interprets "E" as new Volumes (SPACE ITSELF). Thank you kindly.
Excellent -thank you so so much. Maybe, and a theoretical maybe at that , with of curse CIG Theory in mind, and to further vindicate Halton Arp, and with the Cosmological Non-constant in mind, and to offer that Albert E. has gotten a final word over Neil's B., the following could be considered:
According to CIG Theory, the most Dark Energy will be created at a time when the most Energy (light motion of matter) is being released, actually the creation of Space from Matter (not Space from Space as is the current discussions among Cosmologists). So, a slowing over time of Dark Energy will be evident when that light in the Universe has already become Space and as such there is little light leftover to become more Space. This will be gradual. I am trying to explain in the context of CIG Theory why you are seeing the slowing promulgation of Dark Energy over time, since there is less light Matter to turn into Dark Energy (Space). In the EMS the Dark Energy wavelength will be very very long, shorter for Dark Matter, still shorter for Visible Light, and shortest for Black Holes, the full curvature of Spacetime. Please look at CIG Theory in the context of your and Adam Reiss' & team new findings of a weaker Dark Energy , of Mariangela Lisanti's Dark Matter waves, of Halton Arp's Red Shift Anomalies, of the Measurement Problem, and of the Vacuum Catastrophe. So, the greatest expansion (Hubble Non-Constant) will take place when there exists the most light in the Universe and when there is no light left, the expansion of Space will stop. The Hubble Tension can be explained away as in the early Universe there existed a propensity for less light to escape and become the long long longest wavelength Dark Energy. Then at a later time, the light was much more pronounced, and the fast moving matter unfolded to become the Dark Energy. that Energy is weakening as the light fades.
A comment I left on my TH-cam website:
The intent herein is to provide a new definition of space consistent with the CIG Theory, which has already offered a new definition of Matter. That new definition of Matter is: That which has mass, consists of the curvature of space-time and has an element of motion. While the current definition of space in its simplest form customarily is: "a boundless three-dimensional extent in which objects and events occur and have relative position and direction" As can be seen, since we have redefined Matter in the context of the curvature of space-time, we must also redefine "Space" as well, herein and as best I can, as follows: Space is that three dimensional extent in which objects and their events occur, wherein those objects of Matter are they themselves curved space-time, wherein the aforementioned space consists of and emerges via the unfolding of that Matter into various volumes and densities of Space by way of opportunistic rates of motion of Matter. In it's simpler form, Space is unfolded Matter, emergent from rates of motion. That's it and if I come up with a better definition or if someone else would like a try in the context of CIG Theory, please have a go at it. In this manner, a particle can become spatial and go through both slits in the double slit experiment.
And so much more.
OK - With great Scientific fanfare, I am going on record that CIG Theory explains and resolves the Hubble Tension issue, this, without even fully understanding it yet. Tossing out the Scientific Method, relegating actual knowledge to the Kindergarten Room - perhaps even Romper Room, I have so much FAITH in CIG Theory that I just BELIEVE it is the solution. Approach the TENSION from recognizing that the Red Shift Anomalies of Halton Arp introduce their own expansion rates as each star (Galaxy and/or even ATOM) is its own BIG BANG, and this through the history of the BANG BANG BURRITO up until now . MTS is the basic equation. Please learn CIG Theory. I will learn the Hubble Tension and further provide structural support for the solution.
A quick note concerning the Core-Cusp problem. Though not mentioned in the book "I Have Become Space" or Parts I and II of this presentation, nonetheless it can be seen that CIG Theory predicts the observation curve in:
th-cam.com/video/Xe7unoW0C6g/w-d-xo.html&ab_channel=AslanT
Therefore and whatnot CIG Theory resolves the Core - Cusp problem in my opinion. That's just my opinion.
From recollection, I think the book "I Have Become Space" briefly mentions the vacuum catastrophe. Here are some supplemental support comments:
As we know, CIG Theory reinterprets Einstein's Field Equation in terms of the "=" sign, as opposed to a proportionality only.
Matter is curved spacetime and space is unfolded matter.
And, as regards the worst prediction in the history of Physics, perhaps some mathematician could learn CIG Theory and calculate that the value obtained via the Standard Model Quantum mechanical version as represented by the 10 to the 93rd g/cm3 Zero Point Ground State Matter that has not yet fully reached its spatial dimension. How much faster would that matter have to travel to reach the full spatiality of the vacuum density of 10 to the minus 29 g/cm3 ? Then, this difference in the rates of motion of the entities will renormalize the values.
One may see that the Ground State responsible for the so called Standard Model Zero Point is actually the slowest state, and therefore the most massive. Then it is no wonder that the 10 to the 93rd g/cm3 value is so much more massive, as the mass has not yet turned into the vacuum.
In the graph at 3:17, and the accompanying comments, it is stated that Zero Point Energy or Vacuum Energy is the lowest possible energy that a quantum system can have, and 3:41 states that the ground state (1/137) is the lowest Energy. But the lowest energy (rate of motion) is the most massive per CIG Theory. Therefore, the 10 to the 93rd g/cm3 exists as the unit area is so much more massive as it has not turned to space. The space exists as 10 to the minus 29 g/cm3 - so much more diluted density. The Ground State is actually the greatest density mass since it is the slowest. CIG Theory explains the Vacuum catastrophe in this manner.
The times above are taken from:

QM & GR as regards the Cosmological Constant or Vacuum Catastrophe Problems are looking at two different spatial densities. The fist Bohr orbit of 1/137 "c" is still very massive. You cannot compare this with the open vacuum. The lowest energy level has nothing to do with the vacuum of space.
