Big Bang Bonanza with Neil deGrasse Tyson & Brian Keating - Cosmic Queries

What happened before The Big Bang? On this episode, Neil deGrasse Tyson and comic co-host Matt Kirshen answer questions about inflation theory, multiverses, the cosmic microwave background, the formation of our universe, and the possible end of the scientific method with cosmologist Brian Keating.
When did the need for inflation theory start? We travel back to the 1920s and the origins of our expanding universe. What’s the difference between inflation and expansion? Discover quantum fields, quantum fluctuations, the Heisenberg uncertainty principle, and dark energy. What sparked the Big Bang? What caused the irregularities in the cosmic microwave background?
What was Albert Einstein’s biggest blunder? What was the early universe like? We explore what plasma is and why it’s the cosmic microwave background and not other wavelengths. Find out about debates in cosmology about the impacts of inflation theory? Is it bad for society to accept inflation? We discuss the concept of the multiverse and how an article in Scientific American has led to a geek fight.
Does inflation theory spell the end of the scientific method? How much of the universe expanding will be factored into interstellar travel? What are some new discoveries from the BICEP project? Learn about efforts to prove inflation theory, cosmic acceleration, and the different versions of multiverse theory. Did our universe start and end with The Big Bounce? If the CMB is expanding outward, how can we see it if it's past us? Finally, will it ever be possible to see beyond our horizon?

[@georgeleos8219]

Thermal dynamics are the bonding of thermal energy being impacted by a alter element creating a calibrated or reactive effect. Example. Using nuclear power 2 run a sub. We did not make uranium. It was found and manipulated and harnessed based on our awareness of an element. So this means at some ol point in time. Blah blah years ago. Our earths core absorbed said element. And said element wanted 2 keep existing. So it bonded with materials 2 cover it. And said materials fed off these bonded mass acquired elements. Rocks soil water. Gold silver blah blah blah. And these elements that are expelled from the core are escaping and cooling in our planet 2 escape collapse and non existence.

[@georgeleos8219]

Ok 22:05 in just watched hawking theory and controversy with E=Mc2. Now if we take 2 bombs with sand. Fire the into space and impact one another. What happens. My theory comes into play. Leotheory. Does this controlled even in no gravity? Change the make up of sand? Given enough heat and quantified and time observed experiment happens on earth with gravity and known elemental absorption. What happens in space when a know small matter is destroyed at an observed level. Case in point does this change the bonding element of positive or negatively charged particles thrusted into dark matter? We cannot quantify and process elements that are microscopic. Happening at the speed of mili seconds resulting in the Leo theory decomposition and absorption of atoms and singular cells of organisms bonding? If proceed mass acquires gravity it can establish and manipulate the cellular breakdown of its mass. Depending on the situational and occupied space in now established time.

Hey Neil! I was watching one of your videos about earth being spherical, and you were talking about how most things in the universe favour that shape; ie other planets. I am not a flat earth guy but I was wondering if you could ever go into explaining what we know about why planets and stars are round, yet galaxies are disk like. As well if planets have general shapes is there a shape rule of thumb to stuff like nebulae?

[@jaschoudhury18]

[@Robbie_jojo]

Thanks Dr Neil and Brian

[@ZeroOskul]

29:50 Light is not gravitationally bounded and, unlike most other stuff, it stretches with the expansion of the universe. We can tell distance through space by measuring light and radiation from far-off objects and we gauge that distance not by how red-shifted the light is at source but by how much it has been stretched by its traversal through the expanding universe.

[@ZeroOskul]

@@ArienMasterpiece Oh? Please correct it.

[@ZeroOskul]

@Brandon Letzco Gravity is imaginary and it was replaced with General Relativity in 1919, thanks to the Einstein/Eddington Eclipse Experiment: EEEE 1919. Time and space are a substance which mass distorts. The closer to a center of mass, the slower time goes. Time is relative to the observer, and the only way to say that a body is in motion is to make the distinction relative to a second body through space. The closer to the speed of light you travel through space, the slower your passage through time. Time and space are a unified substance that is Spacetime, and traversal through one is contingent on traversal through the other. As light approaches the event horizon of a Black Hole it slows down and its passage through time slows down and at the event horizon the rate of time relative to space is equal to light's rate through space relative to time so escape velocity supercedes lightspeed. Speed being distance through space divided by elapsed time, as 60 miles per hour is sixty miles over sixty minutes but unless one is actually traveling sixty miles it is easier to say the exact distance at a rate of one mile per minute. So, anyway, things tumbling in space are effectively slowed down in time by more massive objects and not drawn to them but unable to escape their path based on trajectory. There are two clouds of space rocks called the Leonids and the Perseids and every year our planet crashes through them, and because Earth is rotating and tumbling and wobbling on a mostly even path around the Sun, and because the meteors are tumbling and bounding around each other they hit the Earth on all sides. We are traveling just over 100,000 miles per hour, about 2.5 million miles per day, around the Sun and with it as it moves along around the Milky Way with the Lanikea supercluster, at many relative speeds compared to other galaxies and extragalactic bodies.

[@Critical.J]

If the universe is expanding why do the star constellation's remain the same????

[@ZeroOskul]

@@Critical.J Star Constellations DO change over millions of years because Earth is riding the rotating Milky Way Galaxy around Sagittarius A*, our galaxy's Central Black Hole. Intergalactic space is expanding. Galaxies are NOT expanding. Stars are within galaxies. All the stars visible from Earth are within the Milky Way Galaxy. The Andromeda Galaxy is in the process of crashing into the Milky Way Galaxy but outside The Local Group of Galaxies everything is moving away from us because space, itself, is expanding between the galaxies.

[@ZeroOskul]

@Brandon Letzco Yes, gravity is imaginary. There is no force pulling you to the center of the Earth, you are being pushed through space by Planet Earth like a person in a car being pushed into their seat. According to Newtonian gravity there should be a planet between Mercury and The Sun. Before General Relativity, astronomers hunted for that planet, it was even named: "Vulcan" because it would be ridiculously hot. But no plane Vulcan was ever found because no such planet exists because "Newton was wrong."* He made a great guess bases on observations in his own time, but he did not have a full dataset to work from. Planet Vulcan, and all of Newtonian gravity, is imaginary. *Quoting Einstein.

[@XxTheAwokenOnexX]

The early universe was born out the previous universe, before the big bang event happened. Imo

[@Dyslexic-Artist-Theory-on-Time]

This theory explains how the big bang and the photons from the Cosmic Microwave Background Radiation can represent the beginning of our time line. And how the cosmological arrow of time with the Universe expanding from the big bang into the future is based on the same geometrical process that forms the concept of time that we have in our everyday life. The photons of the CMBR have a specific wavelength relative to the current temperature of the Universe. When the background radiation was formed, the temperature was higher and the wavelengths of the photons were much shorter. The wavelengths have grown a little over a thousand times in size; the Universe has expanded a thousand times in size in all direction over the same period of time. The volume has grown more than a billion times what it was then. In this theory only the interpretation changes, the physics remains the same! The process explained so far is relative to the photons. What I mean by this is that spherical photon oscillations or vibrations are forming the expansion of three-dimensional space forming a cosmological arrow of time, with an individual arrow of time for each object with their own reference frame. It is because this process is relative to temperature that we can have the same process on the very large scale in the form of plasma and at the very short scale relative to the atoms of the periodic table. Just as we have photon, energy levels cascading down from the big bang we also have photon energy continuously cascading down from the sun. This process is very beautiful and easy to understand. The photons convert potential energy of the electron into kinetic energy, the energy of motion. The main difference between potential energy and kinetic energy is that potential energy is the energy of what can happen, and kinetic energy is the energy of what is happening. By converting potential energy into kinetic energy, photons spherical oscillation form a probabilistic future in three dimensions with one variable in the form of time. This is a geometrical process, of spherical symmetry forming and breaking the spherical symmetry is broken forming dipoles that have a two dimensional aspect as in positive and negative charge. This process of energy exchange forms our ever-changing three-dimensional world with a two-dimensional aspect in the form of a past and uncertain future. A process of spherical symmetry forming and breaking would form the potential for entropy or disorganization with a built-in potential forever-greater symmetry formation that we see in the complexity of cell life and in the potential forever more abstract mathematics.

I'm no expert, but effectively no. The heat energy from those stars are so many thousands of lightyears away that any energy that is brought to us would be incredibly miniscule.

[@ManorexicPanda]

I do not believe so. The sun is the main source of energy, besides the energy we generate on earth via wind, electric. Sun stays Burning by reactions of nuclear fusion to stay glowing hot. Akin to metal being heated up and getting that “glow” effect. Most stars are sooooo far away that the light we see , that goes into our eye, could be years old! The light from stars most likely had been traveling for years . So you are seeing what the star looks like in the past

18:59 As a fan of AXP I love it when Big Bang apologists acknowledge their presuppositions. It puts cosmology in terms that theological apologists can grapple with, which makes it a useful tool in teaching religious people about a universe many orders of magnitude greater than their gods; even greater than the gods of Spinoza and Einstein. That being said, I suspect that Brian meant to say that the null hypothesis is that there was no inflation, and their experiments attempt to disprove the null.

I have an out-of-the box idea about dark energy. Keep in mind, I’m not an astrophysicist, I have a degree in Computer Engineering. Has the possibility been tested, that empty space may behave differently than space containing particulate matter? My idea is that empty space might clump together in a bubble and take on repulsive (anti-gravity) properties. Would an astrophysicist think about that, and tell me why it’s dumb? I’d appreciate it.

[@redonk1740]

To suggest that scientists have a moral obligation to give an explanation to the public implies that it would be immoral not to. Although I believe that it would be morally virtuous to share knowledge, I don't believe that withholding knowledge is immoral by default. Inaction is amoral by default. Sure, there may be specific situations/circumstances where it would be immoral to withhold knowledge, but nobody is under any kind of moral obligation to explain themselves. That's why you get to pat yourself on the back for what you do. We don't praise people for not doing immoral things - that's to be expected. We do however respect/support/praise people for taking morally virtuous actions, such as sharing knowledge with the public.

A slightly better answer to why we can see the cmb... When the universe cooled and the cmb happened. This happened basically everywhere (not all at once). Every point in space if you will. We can see it because there hasn't been enough time for the furthest reaches that could have sent a signal to pass us by.

Neil and Chuck, have you done a star talk about light/electromagnetic spectrum? Like a broad overview? I have so many questions. If a photon is massless why does it have a speed limit or why does it react to gravity or why does it knock around quantum particles? How does a being in the 4th dimension perceive the electromagnetic spectrum with respect to time? What can I do to join the podcast to ask these questions? I don't really have any credentials except that I went to college for engineering and have done open mic stand up. I am like a combo of the two of you except significantly less knowledgeable than Neil and half as funny as chuck. Although I do think Chuck and I would have some good laughs.

7:09 The job of a scientist is not to prove why ideas are right but to "find the flaws" and show why ideas are wrong. ONLY when an idea cannot be proved wrong it is presumed to be right.

The Japanese word is “tsundoku”. It means to “pile up books” that are unread.
