How about a free prank email?

Hey There,

How has your day been? I am sure you are tired after all of the work you’ve done. Anyway, I was wondering if you could do me a favour and do an online survey for me. It should not take more than 10 minutes to complete and would mean a lot to me. I don't want to ask anyone else because they might think it's too much hassle or will not want to help me in any way.

It is completely free so please just help a fellow out and complete this survey for me: https://forms.gle/8pj5N3uqQW8r1AZXi9 .

Thank you very much for your time and I look forward to hearing from you soon!

Best,

Your Name

TED Talk: How to be in two places at once (or more) using quantum entanglement. [SOURCE] "Leonard Susskind explains the science of quantum entanglement and how it could make teleportation a reality. Theoretical physicist Leonard Susskind explains why information cannot pass faster than the speed of light, and shows how to use quantum entanglement to allow communication between widely separated partners." See also:  What is Quantum Entanglement? "Entangled atoms can share a single physical state, no matter how far apart they travel. This is called quantum entanglement, and it's a powerful form of communication." Entangled Photons (Quantum Entanglement) "What if two photons can be perfectly entangled? A new experiment demonstrates for the first time that it is possible for two photons to be entangled while travelling along different paths. The result may open the door to fundamental tests of quantum mechanical predictions in the realm of gravity." Quantum Entanglement Defined "Entanglement occurs when the particle states of two particles are correlated in a way that specify how they will react to each other. This feature allows measurement of quantities that cannot be measured on single particles, such as their position and momentum. It is a very powerful concept, which was first described by Einstein 100 years ago." Nonlocal Communication and Quantum Entanglement  (3 min video) "Consider a pair of entangled particles A and B. By sending the spin of particle B to particle A, you are able to transmit information from one place to another instantaneously. We call this communication non-local. The question is whether this type of instantaneous communication is possible in the usual realm, on a macroscopic scale. According to quantum mechanics it's not possible but in the last decade there's been convincing experimental evidence that it just happens in the micro world. There's a new chapter in the book of physics and it's called non-local communication. Let's rederive the probabilities of non-local communication. " [2:00] Collapse the Wave Function (2 min video) "I want to tell you about some weird stuff that is going on that I believe we could use for time travel, wormholes, teleportation, and a little bit less bizarre things like crystal healing. " [2:40] The Einstein PodCast (1 h 30 min audio podcast) "This week physicist and science communicator Lawrence Krauss talks with theoretical physicist Leonard Susskind about quantum mechanics, entanglement, black holes, and super colliders. " [1:40] Entanglement and Quantum Erasure (2 min video) "Entanglement is one of the most startling aspects of quantum theory. In this demonstration we use a truly entangled pair of red photons. One is sent through the interferometer and the other is measured in a polarisation analyser. The interferometric path has two polarisers which are set so that, if the original photon was vertically polarised, only a horizontally polarised photon could pass through both slits (this is called an 'entangled' state). This entangled state will be destroyed by passing it through an analyser which interferes with light in a different way to the interferometer. This is called 'quantum erasure'." [3:00] How to entangle two atoms (2 min video) "This video describes a method for entangling two atoms using a laser. The method is described by Didier Sornette in his paper "An atom entangled with another atom" and can be found in the arXiv version of the paper here . The method works for any type of atom." [4:00] Quantum Mechanics: A Brief History (7 min video) "My purpose for this video is to give you an introduction to some of the basics of quantum mechanics. If you are not sure where exactly you are on this path, it's a good time to pause and take stock. What I want to do is give you a glimpse of the story that we will cover, give you a sense of the most common misconceptions and some suggestions for where to learn more about it." [6:00] Quantum Mechanics is Easier Than You Think (5 min video) "There has been a lot of commotion about quantum mechanics recently. And not without reason. After all, when Nature forces us to think differently about our most fundamental bits of reality, this is bound to have profound consequences on our view of the world. But despite this uproar, quantum mechanics isn't actually that difficult. To prove it, I'm going to explain it to you using just high school physics. No math. No abstractions. No hand waving. Nothing more than we are all familiar with from our pre-university education." [5:00] Quantum Entanglement Under The Microscope (3 min video) "Entanglement is a property of the quantum world in which particles that have interacted in the past (even when very far apart) can share properties through Einstein's famous 'spooky action at a distance'. In this experiment, the entanglement between two individual entangled photons is measured using an interferometer. The result shows that the quantum state that describes each photon has been altered as a result of the interaction. This is one of the first demonstrations, to my knowledge at least, that evidence exists for entanglement between entangled atoms." Understanding Quantum Mechanics (2 min video) "This video provides an introduction to quantum mechanics. It covers the standard textbooks and you will learn about the rules of quantum mechanics used in experiments. The video also covers some of the concepts that are more difficult to understand, such as superposition and hidden variables." [5:00]

Quantum Entanglement and Einstein's Relativity (2 h 38 min 14 sec) "The Big Bang Theory predicts our universe is expanding.

Conclusion: Space is not boundless, but finite.

This is well-established by science. When we examine space as a whole, the galaxies appear to be moving away from each other - an understandable conclusion given that the entire universe is expanding. In this scenario, it is easy to logically believe in the fact that space has started out small, and has been ever-expanding since its creation - an idea known in physics as 'The Big Bang'.

However, there also seems to be a limitation to this 'boundless' expansion - for instance when two lights are shined on opposite ends of a room with an opaque wall in between.
