How Did The Universe Began?
The Origin Of The Universe Einstein's general theory of relativity, on its own, predicted that space-time began at the big bang singularity and would come to an end either at the big crunch singularity (if the whole universe recollapsed), or at a singularity inside a black hole (if a local region, such as a star, were to collapse). Any matter that fell into the h…

Black Holes Explained
Black Hole Introduction It is said that fact is sometimes stranger than fiction, and nowhere is that more true than in the case of black holes. Black holes are stranger than anything dreamed up by science-fiction writers, but they are firmly matters of science fact. The scientific com munity was slow to realize that massive stars could collapse in on themselves, unde…

Multiverse And Many World Theory Explained
Introduction The multiverse idea states that there are an arbitrarily large number of Universes like our own out... [+] It's possible, but not necessary, for other pockets within the Multiverse to exist where the laws of physics are different. Let's us understand in detail what actually is mutiverse and many world theory. The Many World Theory Schrodinger'…

Heisenberg Uncertainty Principle Explained
Introduction Heisenberg's Uncertainly Principle holds good for the quantum world irrespective of the challenge posed by the EPR Paradox. Thus, the Uncertainty Principle puts a severe limitation on our ability to measure accurately the true position and speed of a sub-atomic particle, simultaneously. This remains one of the fundamental truths of the microscopic wo…

The Causality Effect Explained
Introduction What is the effect of something moving faster than the speed of light? This is an interesting question we will answer in a while, but before that, let's look at one more aspect of our microscopic world. Werner Heisenberg (1901-1976), a German physicist who is regarded as the creator of Quantum Mechanics, contributed immensely to its development. The …

Schrodinger's Cat Experiment Explained
Introduction Let's take a look at one of the Quantum Mechanics' most talked about and undisputed mother of all thought experiments, Schrodinger's Cat. Erwin Schrodinger (1887-1961), an Austrian physicist and theoretical biologist, is considered one of the founding fathers of Quantum Theory and the creator of the Schrodinger Equation, for which he won the …

Double Slit Experiment Explained!
Introduction In order to truly grasp quantum queerness, we must quickly do a real experiment called Double-Slit Experiment (this is not a thought experiment but actually performed in the physics lab). It is a famous starting point to understanding the intriguing nature of the QM phenomenon. This experiment is based on the original concept devised by Thomas Young (177…

Can A Particle Be At Two Different Places At Same Time?
Introduction Before we move on, let us make this quantum concept clearer. The wave function is a true representation of the way we all exist, although it is difficult to imagine. It is really a mathematical way of representing the waviness of matter or a particle. The wave function of an electron or a car may be spread all over the universe but each of them has a ver…

Is Space Time Real?
What Is SpaceTime? In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. The fabric of space-time is a conceptual model combining the three dimensions of space with the fourth dimension of time. Spacetime diagrams can be used to visualize relativistic effects, s…

Can We Travel Faster Than Light?
Can We Travel Faster Than Light? Introduction The speed of light is 299,792,458 m/s. The speed of light is kind of very close to the speed limit of the universe, which is exactly 300,000 km/s which is 300,000,000 m/s. So, traveling faster than light requires us special equipments and spacecraft to make it possible and also some of the weirdest ways of traveling in sp…
