The discovery of the fundamental particles of the Universe allowed physicists to gain a new insight on what the conditions during the Big Bang was like. Using particle accelerators, physicists are able to imitate the extreme conditions that occurred a fraction of the nanosecond after the Big Bang. Particle accelerators such as SLAC and the Large Hadron Collider (LHC) in particular are specialised at testing the different theories of particle physics.
(Close to) 50 years after the death of Albert Einstein, I was hunched over my computer looking for a way to pass time, when I decided to acknowledge the crazy notions of a super genius. So here we go:
- Moving objects gain weight, shrink in size and experience time more slowly than a stationary object. Crazy, but follows logically from Einstein’s Special Theory of Relativity (STR). Not only have the three ideas above been proven mathematically, but also experimentally. Although, quite sadly, we can’t experience the effects of STR in our day-to-day lives, NASA needed Einstein’s wisdom to get to the moon.
- There is no way to know whether you are moving or simply stationary. This was enough to elicit the fury of physicists around the world. Silly as it sounds, it is again a logical idea. Ever look out the window of a moving train and ask yourself whether you are actually moving, or whether the background you observe is moving? Einstein did. And as a result of that nonsensical question, Einstein went on to assert that motion is relative. Only B can determine whether A is stationary or not. Moving on . . .
- Light is affected by gravity and can be bent. Or rather distorted by gravitational attraction. It was a solar eclipse that made Albert Einstein a scientific celebrity in less than 24 hours. His General Theory of Relativity (GTR) was proved when a very determined Englishman trekked to Africa to photograph and prove that during the solar eclipse light was distorted by 1.7 arcseconds, the precise predictions of GTR.
- We can make portals through space and time. No, it isn’t just science fiction. Einstein proved for the first time that we can in fact time travel if we produce a wormhole. This gave the inspiration for Christopher Nolan to make his film Interstellar. Wormholes can also be used for teleportation. It is believed to be a wormhole that Coraline crawled through to reach the “Other Universe”.
- The most famous equation ever. Also easily the most misinterpreted equation ever. Annoyingly, the mathematics used to obtain this equation is, according to the Heinemann Physics Textbook “outside the scope of this course”, but the equation itself is very simple. The total energy of an object is equal to the mass of the object when moving multiplied by the speed of light squared. When the object isn’t moving, the equation changes very slightly to , where is the “rest mass”.
However, as much as we can praise Einstein, he also made a widely publicised mistake. And then made another one. In fact, Einstein publicly rejected and completely abased a whole new branch of mind-bogglingly theoretical physics.
Have you ever wondered whether or not parallel universes exist? And if they do, how is it possible? To answer this question, let’s take a look at the notion of dimensions. Dimensions are simply the different facets of what we perceive to be real. We live in a three dimensional world and are familiar with the components that make up the three dimensions – that is we see objects in our immediate world as having a length, width and depth.
However, it seems that the three dimensional world is not the limit. In the light of string theory, scientists now believe that there may be many more dimensions beyond the three we are familiar with. In fact, the string theory postulates that it could be possible that 10 dimensions exist in the universe.
