Brian Greene is my favorite science communicator up there with Carl Sagan. He is so articulate and easy to understand while possessing such a rich vocabulary. The way he layers his sentences is so poetic and entertaining that it's impossible to be distracted.

[@dzenacs2011]

Dont like how hes think that humans is not that important just byproduct of "great universe".thats not encouraging way to life Greene .

[@prophetofthesingularity]

@@dzenacs2011 He is not saying that humans are not important, he is saying we are not important to the universe. He is saying our importance does not come from an external source because there is not one. What we do is important to us. If life is a video game we are in sandbox mode not an RPG where we have pre-destined quests to do. If anything that makes us more important because the achievements of humanity to get this far was done without aid and by us alone.

[@inglestopia]

The main difference is that Sagan was more of an intolerant atheist.

[@prophetofthesingularity]

@@inglestopia understandable considering the lack of tolerance religion has had for science for 1,000s of years. Such as insisting the universe revolves around the Earth and Placing Galileo on trial for heresy for stating so and imprisoning him for stating this truth. Religion has never tolerated the truth so why should Atheists tolerate religion which is based on ancient myths and retold legends and not facts?

[@inglestopia]

@@prophetofthesingularity I prefer the mindset that Greene has, he doesn't need to disqualify people for believing something or hating other beliefs like if religion as a whole is completely bad when it's not, it has also positive things. Of course, many people have died unjustly, just as religious people have died because of secular atheists, they reacted in the same way because they wanted to impose their atheistic thought, how did religions react? Religious fundamentalisms were formed, including Islamic terrorism. Both extremes are indefensible and unfortunate, but it is not good to add fuel to the fire and seek revenge on one side, so intolerance will never end. I have to read more of Sagan to be honest to have better understanding but I remember like he hated religion a lot, same case as Richard Dawkins.

[@pcproffy]

Brian Greene is great because he seems socially competent with great intelligence. Not just a science/math savant who can't communicate with everyday people.

[@2fast2block]

He loves to remain blind to science. The 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LoT shows that the universe is winding down, usable energy is becoming less usable.

Brian Greene is the best. I really wish somebody like him was teaching Physics in my highschool, maybe I would have been more interested back then. His series on Nova, "fabric of the cosmos" is incredible.

[@chrisruskai9341]

I agree with the sentiment that he is the best, but explaining things at the high level on a TV documentary is a lot more entertaining then spending hours writing out equations over and over again. I think in the classroom setting, your interest level would have been the same

The theory of everything according to humans that believe their intellect evolved from a monkey's brain. If the light waves from the sun were 8 minutes and 20 seconds in a past dimension of Einstein's space-time then people on Earth are just imagining the infrared warmth of the sun coming up on the horizon. The communications delay between Earth and Mars is approximately 20 minutes. We're either viewing the light from Mars in the future, Einstein's past dimensions of space-time or in real time, which do you think is more logical? Einstein's relativity is wrong light has no limitation of speed; it cannot be slowed down because it isn't moving. From every vantage point in the universe light is omnidirectional-instantaneously traveling in both directions. Light and electromagnetic waves are independent of each other. According to Einstein's relativity-time dilation's, photos taken of the Earth from the Discovery Space station traveled from the past to the future violating the laws of physics, conservation of energy and common sense. According to Einstein's projectile light particle proton light has a (constant speed) of 186,000 miles per second moving through spacetime, but if light has a (constant speed) then moving clocks cannot run slow through spacetime! :-) The speed of light according to Einstein's relativity is 186,000 miles per second, but according to physics if two mechanical watches were synchronized on earth and one traveled across the universe and back, there would be no difference in time between the mechanical watches proving the speed of light is instantaneous as the only way a mechanical watch will run slow is if you tighten the main spring. Big Bang, Einstein's relativity-time dilation and nearly all of science debunked. Using optical clocks, lasers and GPS to prove Einstein's time dilation-space-time curvature is like using a metal detector to find gold at Fort Knox. The closer you are to the electromagnetic fields, mass and gravity of the earth the more light bends aka gravitational lensing. The closer you are to the electromagnetic fields, mass and gravity of the earth the more light bends aka gravitational lensing. If the speed of light is constant then past and future dimensions of spacetime and an expanding universe would not be possible, obviously destroying the twins paradox as each twin cannot move faster or slower than the other. Einstein would have made a great used car salesman :-) Light waves can stretch, bend-curve and occupy a state of superposition, whereas the hypothetical Einstein projectile light particle (photon), a particle that has never been observed cannot. Unlike a TV or computer monitor the images we are viewing in the universe are in real time, not a series of frames that create the appearance of a moving image. There are no DCU digital convergence circuits in space yet Einstein's disciples believe the light and moving images they see in the universe aren't really there, they're just video recorded images of the past 13.8 billion years. You could lead a cult to water, but you can't make them think. Neither time, energy nor mass can create itself into nothing, reside in nothing or expand into nothing simply because nothing has no properties. Time and space are independent of each other, not material bodies or fantasy unions that magically stretch Time, energy, and matter like a rubber band into space-time dimensions. Monkey see monkey do, the science of monkeys have brainwashed you. Will the James Webb Telescope view the birth of the first galaxies? Nope, the universe goes on to infinity. Neither time, the atom, energy nor mass can create itself into nothing, reside in nothing or expand into nothing simply because nothing has no properties. The James Webb Space Telescope is not a time machine, you can’t travel back in time to view the beginning of the universe with telescopes that were made in the future :-). Light and electromagnetic waves are independent of each other. If science uses Einstein's wrongly theorized speed of light like an odometer to calculate past dimensions of distance and time, then using that same method to calculate forward dimensions of distance and time would mean the Big Bang was created and expanded in the future before time existed. Unlike a television or computer monitor the images we are viewing in the universe are in real time, not a series of still image frames that hypothetical Einstein projectile light particles photons create to give us the appearance of a moving image :-). The speed of electromagnetic wave is 186,282 miles per second vs Einstein's projectile light particle proton at 186,000 miles per second. Is this a coincidence or did Einstein plagiarize yet another phenomenon to fit the math of relativity? Electromagnetic waves in space can neither slow down or speed up, this is consistent with the law of conservation of energy. If light slowed down, its energy would decrease, thereby violating the law of conservation of energy so the speed of light is instantaneous and cannot travel slower than it does. If Einstein's projectile light (particle photon) had mass it's light could not travel across the universe, high speed particles traveling at 186,000 miles per second would break the Hubble and James Webb telescope mirrors, debunking the speed of light, Big Bang, Einstein's relativity and any science that uses relativity in their theories. Everyone knows cell phone electromagnetic radio waves travel both ways, yet Einstein's disciples believe time energy, mass and light can only travel one way back in time. If you simply run the Big Bang theory in reverse you reveal the insanity of Einstein's relativity and Big Bang theory. If the expansion of the Big Bang were true, time, energy, mass and light would be in the future from the vantage point of an expanding singularity-Big Bang and planet Earth would now reside in a past dimension of Einstein's time dilation (moving clocks run slow) space-time 13.8 billion years ago :-). It's truly amazing how the science and politics of the left are able to keep people denying reality, there are no DCU digital convergence circuits in space, yet Einstein's disciples believe the light and moving images they see in the universe aren't really there, they're just recorded images of the past 13.8 billion years. Pretending not to notice the gross contradictions-pseudoscience in Relativity is typical of Einstein's disciples, devaluing the source of any information that's in contradiction with their beliefs-theories. You could lead a cult to water, but you can't make them think. If the light from the universe travels to past dimensions of time then it's light is also traveling into future dimensions of time (instantaneously). “And God said, Let there be light: and there was light.” a state of superposition where time and gravity run inwardly, outwardly, in all directions in the same time frame, similar to the electromagnetic field having no beginning and no end. "I am the Alpha and the Omega, the First and the Last, the Beginning and the End" Revelation 22:13. Disciples, remember thy 1st commandment, thou shalt not question thy lawgiver of relativity for blasphemers are the devil's pawn. Let thee not dwell in dissension of our Lord Albert, shun them, drive them back to their jungle lair amen.

Light and images travel both ways, aliens in distant galaxies using similar James Webb telescopes would also see the light and images from our Milky Way galaxy but if they believe we're in the past dimension of big bang space-time they'll never bother to contact us. According to time dilation there is no universal time in the universe so all the stars galaxies and planets have different coordinates in space-time, if that were true astronomy software wouldn't work, light-speed and space travel couldn't be calculated. Explain how the James Webb space telescope can time travel into the past to view the physical properties of matter as it was 14 billion years ago with the simple technology of a telescope :-). Explain how you can see and feel the infrared warmth of the Sun coming up on Earths horizon when light-speed (Einstein's space-time) tells us the Sun is supposedly 8 minutes and 20 seconds in a past dimension of space-time . If the speed of gravity and light are 186,000 miles per second and the Sun is 8 minutes and 20 seconds in Earth's past dimension of space-time, explain how Earth and planets in our solar system can maintain orbits without gravity? :-) Relativity debunked with celestial mechanics. The time traveling Voyager 1 space probe launched in 1977 is still communicating with Earth having left our solar system, even if it traveled another 14 billion years provided the circuitry held up it would still communicate back to Earth. Light and images travel both ways, aliens in distant galaxies using similar James Webb telescopes would also see the light and images from our Milky Way galaxy. Just because the light and images from planet Mars are assumed to take 20 minutes to reach earth does not mean the Martians have traveled into another space-time dimension where the stars, planets and galaxies are in different locations from Earth. Time and distance cannot be relative to other objects in space-time as that would violate the law of conservation of energy. To travel distance requires potential energy, an observer can have no effect on a moving objects kinetic energy-Relativity debunked. If there is no universal time in time dilation then there are no universal coordinates so time couldn't exist. Explain how moving clocks can run slow without having a universal time :-). Traveling at a different speed from the stationary clock having no universal time, all the stars, planets and galaxies would be in a different place in the universe so distance for the observer could never be calculated. When certain frequencies of light are shined onto metal electrons are ejected instantaneously without delay according to the photoelectric effect yet Einstein's disciples tell us the speed of light is limited to 186,000 miles per second. Doublethink is the act of accepting two conflicting beliefs as truth. Time and distance cannot be relative to other objects in space-time as that would violate the law of conservation of energy. Light travels in both directions, anyone having a conversation with their friends understands this simple phenomenon yet Einstein's disciples believe people on earth are time traveling backwards and forwards in space-time relative to one another. Testing the speed light on Earth is like riding a bicycle up hill, gravity will show you down. The biggest threat to humanity is human stupidity. Explain how you can see and feel the infrared warmth of the Sun coming up on Earths horizon when light-speed (Einstein's space-time) tells us the Sun is supposedly 8 minutes and 20 seconds in a past dimension of space-time.

A mirror is a wave reflector that flips images from left to right, but according to Einstein the images you see are the result of projectile light particle photons being transported into past and future dimensions of space-time. Explain how particle light photons can re-converge their molecular structures in mirrors and how this is done without violating the law of conservation of energy. From every vantage point in the universe light is omnidirectional-instantaneously traveling in all directions (forwards and backwards through Einstein's space-time) while violating the law of conservation of energy. Explain how Einstein's projectile light particle proton can travel all directions having a (constant speed) of 186,000 miles per second. Einstein would have made a great used car salesman :-).

Einstein's projectile light particle proton has a (constant speed) of 186,000 miles per second moving through spacetime and because so wavelengths of light cannot stretch through spacetime! Red-shifts are simply the result of decelerating electrons, as moving electrons of charged electromagnetic waves-light travel through the plasma of the universe each lump (or "quanta") of energy in the electromagnetic waves are charged then discharged to the next lump, eventually the energy dissipates causing the delay in radio communications giving the appearance of time dilation - longer wavelengths in red shift. Will the James Webb Telescope view the birth of the first galaxies? Nope, the universe goes on to infinity. Neither time, the atom, energy nor mass can create itself into nothing, reside in nothing or expand into nothing simply because nothing has no properties.

The faintest stars and galaxies are neither in a past or future dimension of Einstein's space-time, they're in real-time.

The Doppler effect is wrongly conflated with cosmological Redshift. As one approaches a blowing horn the perceived pitch is higher until the horn is reached, then becomes lower as the horn is passed. This phenomenon is caused by the physical movement of a mechanical soundwave traveling through the medium of air, similar to throwing a rock in a pond, the rock creates physical movement in the medium of water. Cosmological Redshifts are merely the GoPro fisheye effect where wavelengths appear to lengthen-stretch from the phenomenon of gravitational lensing. "I am the Alpha and the Omega, the First and the Last, the Beginning and the End" . According to general relativity ie gravitational lensing (a warped field of vision in telescopes) is due to (mass) between a distant light source and the observer. If that were true earths huge mass would distort the light of the observer as well making telescopes unusable. So only other planets in the universe are affected by gravitational waves? In 1916 before it was known that man could travel in space Albert Einstein based his gravitational wave theory on relativity. In 2021 most of us realize if gravitational waves existed in space astronauts would be crushed like an underwater diver traveling to the bottom of the sea. Einstein's disciples defend relativity by saying gravity is a weak force, yeah so weak it affects planets and galaxies just not astronauts, the discovery space station or droplets of water in space?

"Time is the most essential quality of experience while simultaneously being the most mysterious" - Thought provoking and brilliant. I have lost count of time trying to digest that statement.

[@SG937.]

Loosing count at that digestion for some reason makes me think of a litebrite board and the pegs. Although by themselves they remain the same physically... When they come together in the process of a being "digesting" by the "user", that makes an experience and an expression. Also meant to be taken apart. Not be be stuck in one particular pattern. As is the life cycle of the digestion process.

[@jackgreenway4646]

I love it, this makes my mind feel at ease with everything especially death and nothingness. the concept of space and time itself really fills me with joy, I used to get really anxious about it all but listening to these kind of podcasts puts me at such ease, I don't believe in god, never have and never will but I do believe in such a great force of energy, somewhere everything, every being, everyone came from together.

[@Junglebtc]

@@mathewgladden8914 I think your wrong .

Or its pantheism of sorts

[@exploration4]

Well stated, friend.

[@DavidMartin-qt1fx]

Higher level Christian consciousness knows that God is Spirit. Not a father in heaven with genitals. Jesus spoke in parables for a reason. The positive use of energy is Agape Love, introduced to the world 🌎 by Jesus. What was once called the Holy Ghost, then called the Holy Spirit, could now be referred to as Energy. Positive Loving Energy. That can neither be created nor destroyed...

He doesn't know what he's talking about. The 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LoT shows that the universe is winding down, usable energy is becoming less usable. It is clear creation had to be done supernaturally yet it is still denied because people are just too proud to accept that, among other things.

How long does one have to exist to begin to feel a faint understanding of life, the universe, the ultimate destination of we silly humanoids.

[@vindis79]

I like this idea of fear of death that was discussed. I believe we got it all wrong. One can never stop existing at least from ones' own perspective. Remember when you went to sleep and then you woke up? Do you know how much time has passed while you slept? Your experience might tell you it was approximately 8 hours but you don't really know. Might have been 10 years. For you it's only the momement just before you lost conciousness and then regained it again. So when you die there may have trillions of years passed before your conciousness reappears again but from your own perspective it's a continuous experience. You may not remember what happened before but it is still YOU.
