Theories of the Universe

Image
The Universe is ever expanding, and its accelerating. But what could possibly imply that the universe could collapse into a single atom? Studies by astrophysicists shows that the universe is approximately 13.8 billion years old. So, the universe has a beginning and an end? Or is it possible that the universe is a repeating cycle? String theory was proposed in the 1960’s. It was developed to be a unity between Quantum mechanics and Albert Einstein’s Theory of Relativity. This theory explained most of the events that occurred around the time of young universe. The theory is that all matter are complex strings whose vibrations can determine the properties. Then came the Big Bang Cosmology, along with the idea of Inflation. These theories state that at the time of birth of the universe, it became very large in such a small time, when the universe was less that a second old. This sudden inflation, with huge gravitational differences, caused the formation of huge splotches found in the unive...

Security in the Future

Researchers from the University of Tsukaba in Japan designed a pattern that cannot be duplicated in any way. How is this helpful? Patterns play an important role in many fields of mathematics. Patterns helped many physicists and mathematicians to solve many problems which would’ve otherwise been unsolvable. Many discoveries were possible because of patterns. Some of them are demonstrated using mathematical graphs, and some with natural phenomenon. Scientists recently designed a pattern, that cannot be duplicated or forged by any means. This means that this pattern could be very helpful to eliminate counterfeits and forgery, which affected the economy a lot.  Before we get into the working, let’s see what is a Whispering Gallery. Whispering Galleries are huge places, that are shaped in order to reflect sound waves in an abnormal way. Some galleries are designed so that the sound waves travel to every part of the place, despite there being any obstructions. They are mostly spherical ...
