StarTalk Podcast: Cosmic Queries – Proving Einstein Right
Albert Einstein is, well, Albert Einstein. But, was he right? It seems like a silly question, but, in fact, there’s some history behind it. On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are investigating what it took to prove Einstein right, with Dr. Jim Gates, theoretical physicist and Professor and Center Director of the Brown University Theoretical Physics Center. Jim is also the co-author of Proving Einstein Right: The Daring Expeditions that Changed How We Look at the Universe. We start with some history. Jim tells us about Einstein’s discoveries about space and time in 1905. You’ll learn about the “happiest thought” of Einstein’s life. We discuss how he came to his theory of general relativity and theory of special relativity. You’ll also learn why, even though he first started working on the ideas in 1905, it took him over a decade to get them right. Find out what it takes to provide evidence for mathematical theories in the real world. We discuss Einstein’s exposure to the real world and how that informed his thought process. Jim explains why being a scientist involves swimming in a sea of information. We ponder if Einstein ever thought his theories were incorrect, and Jim tells us why math is magical. Then, we answer fan-submitted Cosmic Queries! Is general relativity incompatible with quantum mechanics? If so, why? Is there a bigger idea that encompasses both ideas? We dive into String theory and how that might play into the equation. We investigate “gravitons” and how their existence would re-shape science. Are the strings in String theory made of something? We explore the cosmic microwave background and debate if a cosmic gravitational background could also exist. Lastly, you’ll hear why some stars in the night sky might be duplicated due to the bending of light. All that, plus, we answer the most important question of all – who has a better mustache? Neil deGrasse Tyson or Albert Einstein? Thanks to our Patrons Beverly Bellows, Christopher Mank, Darrell R.

Hubblecast 110 Light: New test of Einstein’s general relativity
An international team of astronomers using Hubble has made the most precise test of general relativity yet outside our Milky Way. A nearby galaxy acts as a strong gravitational lens, distorting light from a distant galaxy behind it to create an Einstein ring around its centre. By comparing the mass of the lensing galaxy with the curvature of space around it, the astronomers found that gravity on these astronomical length-scales behaves as predicted by general relativity.

Theory that challenges Einstein's physics could soon be put to the test
"Scientists behind a theory that the speed of light is variable - and not constant as Einstein suggested - have made a prediction that could be tested. Einstein observed that the speed of light remains the same in any situation, and this meant that space and time could be different in different situations." Putting the Brakes on Light
"The atoms, now one big atom, act in unison. They are analogous to the photons in a laser, all lined up the same way, producing what physicists call a coherent beam of light. On the quantum mechanical level, atoms have dual personalities, just like photons of light." What is the Inflation Theory?
"The Inflation Theory proposes a period of extremely rapid (exponential) expansion of the universe during its first few moments. It was developed around 1980 to explain several puzzles with the standard Big Bang theory, in which the universe expands relatively gradually throughout its history." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

https://www.youtube.com/watch?v=4tcoZNrSveE The sign of a truly great scientific theory is by the outcomes it predicts when you run experiments or perform observations. And one of the greatest theories ever proposed was the concept of Relativity, described by Albert Einstein in the beginning of the 20th century. In addition to helping us understand that light is the ultimate speed limit of the Universe, Einstein described gravity itself as a warping of spacetime. He did more than just provide a bunch of elaborate new explanations for the Universe, he proposed a series of tests that could be done to find out if his theories were correct. One test, for example, completely explained why Mercury’s orbit didn’t match the predictions made by Einstein. Other predictions could be tested with the scientific instruments of the day, like measuring time dilation with fast moving clocks. Since gravity is actually a distortion of spacetime, Einstein predicted that massive objects moving through spacetime should generate ripples, like waves moving through the ocean. Just by walking around, you leave a wake of gravitational waves that compress and expand space around you. However, these waves are incredibly tiny. Only the most energetic events in the entire Universe can produce waves we can detect. It took over 100 years to finally be proven true, the direct detection of gravitational waves. In February, 2016, physicists with the Laser Interferometer Gravitational Wave Observatory, or LIGO announced the collision of two massive black holes more than a billion light-years away. Any size of black hole can collide. Plain old stellar mass black holes or supermassive black holes. Same process, just on a completely different scale. Let’s start with the stellar mass black holes. These, of course, form when a star with many times the mass of our Sun dies in a supernova. Just like regular stars, these massive stars can be in binary systems. Imagine a stellar nebula where a pair of binary stars form. But unlike the Sun, each of these are monsters with many times the mass of the Sun, putting out thousands of times as much energy. The two stars will orbit one another for just a few million years, and then one will detonate as a supernova. Now you’ll have a massive star orbiting a black hole. And then the second star explodes, and now you have two black holes orbiting around each other. As the black holes zip around one another, they radiate gravitational waves which causes their orbit to decay. This is kind of mind-bending, actually. The black holes convert their momentum into gravitational waves. As their angular momentum decreases, they spiral inward until they actually collide. What should be one of the most energetic explosions in the known Universe is completely dark and silent, because nothing can escape a black hole. No radiation, no light, no particles, no screams, nothing. And if you mash two black holes together, you just get a more massive black hole. The gravitational waves ripple out from this momentous collision like waves through the ocean, and it’s detectable across more than a billion light-years. This is exactly what happened earlier this year with the announcement from LIGO. This sensitive instrument detected the gravitational waves generated when two black holes with 30 solar masses collided about 1.3 billion light-years away. This wasn’t a one-time event either, they detected another collision with two other stellar mass black holes. Regular stellar mass black holes aren’t the only ones that can collide. Supermassive black holes can collide too. From what we can tell, there’s a supermassive black hole at the heart of pretty much every galaxy in the Universe. The one in the Milky Way is more than 4.1 million times the mass of the Sun, and the one at the heart of Andromeda is thought to be 110 to 230 million times the mass of the Sun. In a few billion years, the Milky Way and Andromeda are going to collide, and begin the process of merging together. Unless the Milky Way’s black hole gets kicked off into deep space, the two black holes are going to end up orbiting one another.

Einstein, Black Holes and Cosmic Chirps - A Lecture by Barry Barish
Albert Einstein’s theory of general relativity, developed 100 years ago, predicts the existence of gravitational waves. In February 2016, the Laser Interferometer Gravitational-wave Observatory (LIGO) became the first experiment to observe gravitational waves, created by two black holes spiraling into each other. The discovery became known as the chirp heard around the world. Four month later, a few hours before this public lecture, LIGO announced the discovery of a second signal. This lecture, given by Dr. Barry Barish, LIGO director from 1997 to 2006, explains the physics of gravitational waves, the detection technique used by LIGO, the observations made and the implications these discoveries have on our understanding of the cosmos.
