Quantum mechanics is one of the best-tested theories in science, and it's one of the few where physicists get to do experiments proving that Einstein was wrong.
That's what a team at Griffith University and the University of Tokyo in Japan did this week, showing that a weird phenomenon — in which the measurement of a particle actually affects its location — is real. Back in the 1920s and 1930s, Albert Einstein said he couldn't support this idea, which he called "spooky action at a distance," in which a particle can be in two places at once and it's not until one measures the state of that particle that it takes a definite position, seemingly with no signal transmitted to it and at a speed faster than light.
When the particle takes its definite position, physicists refer to this as its wave function collapsing. Alice and Bob The phenomenon is demonstrated with a thought experiment in which a light beam is split, with one half going to Alice and the other to Bob. Splitting photons.

Why Big Bang Theory is a Misnomer. By Michio Kaku First of all, the Big Bang wasn't very big.
Second of all, there was no bang. Third, Big Bang Theory doesn't tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer. We need a theory that goes before the Big Bang, and that's String Theory. Think of two bubbles with a tube connecting these two bubbles and as one bubble fissions from the other bubble, there is this umbilical cord connecting these two universes. Your Body is a Time Machine. The Origin of Intelligence. By Michio Kaku Michio Kaku: In the entire universe the two greatest scientific mysteries are first of all the origin of the universe itself.
And second of all the origin of intelligence. Believe it or not, sitting on our shoulders is the most complex object that Mother Nature has created in the known universe. You have to go at least 24 trillion miles to the nearest star to find a planet that may have life and may have intelligence. And yet our brain only consumes about 20-30 watts of power and yet it performs calculations better than any large supercomputer. Michio Kaku on the Alien Mind. Transcript Michio Kaku: I love to watch science fiction movies but I cringe – I cringe whenever I see a depiction of the aliens.
First of all the aliens speak perfect English. Not just British English. They speak perfect American English. And obviously they’re a human inside some kind of monkey suit. For example, if we take a look at a bat or a dog, the dog’s brain is mainly interested in smells. So a cat sees the universe totally different than we do and yet we impose our thinking on an alien. Michio Kaku on the Science of Dreams. Transcript Michio Kaku: There’s a whole lore about dreaming.
In fact, Sigmund Freud wrote a book called The Interpretation of Dreams which many people think is the foundation of psychoanalysis. Well scientists now have looked at Freudian psychology and the brain using all these modern techniques. And first of all we realize that perhaps Sigmund Freud wasn’t totally wrong. There are many textbooks which simply dismiss Freudian psychology calling it nuts. And Freud also said there is the ego, the id and the superego, that we are in a constant battle with our desires and our conscious. If you were to see a chocolate cake you would see these three parts of the brain going zippity back and forth like a ping pong ball because you’re constantly debating the pleasure of eating a chocolate cake versus how fat you’re gonna become and all the sugar and the calories that you don’t really need. What is active when you dream is your amygdala. What Travels Faster Than the Speed of Light? By Michio Kaku One frequent question I get is whether we can break the light barrier—because unless we can break the light barrier, the distant stars will always be unreachable.
Most textbooks say that nothing can go faster than light, but that statement actually should be qualified: The answer is yes, you can break the light barrier, but not in the way we see in the movies. There are, in fact, several ways to travel faster than light: 1. Secret of Quantum Gravity, Singularity, Big Bang and Ekpyrotic Scenario explored in two pages. Alan H. Guth. Cosmology michio kaku.
