Most Amazing Concepts in Physics

By: Nikhil Malankar

 

Science deals with many aspects of our daily life. You start your day with the application of Science. Just take an example of the toothpaste you are using or the motion of a wave or even respiration. Everything relates directly or indirectly with Science. Science can be divided in the following parts.

  1. Physics
  2. Chemistry
  3. Math
  4. Biology

From the topic you must have understood that I am going to talk about Physics. OK Then, What concept do you find the most amazing? If you don’t find it on this list then you are welcome to say about it in the comments column. Let me start off with the list.

1. E=mc^2

We all know about this formula. It was introduced by one of the greatest scientists of all time .i.e. Mr. Albert Einstein. This concept is really interesting one and the debate about its correctness is still going on. It gave rise to other concepts like warped space and space time which are also very interesting and deep. It is a very controversial topic and I had also written an article related to this one. The link to it is:

2.Gravity

The most important concept given by Physics to mankind is the Gravity concept without which it would have been impossible to make rockets and other studies related to it. The most famous example to explain gravity was given by Sir Isaac Newton with his Apple Tree example. It is said that Newton was not the first one to observe the phenomenon of gravity but it was Galileo who first discovered it. Anyways, this concept caused a revolution and modern day physics is heavily dependent on this concept.

 

3. Space Travel

Few centuries ago it was impossible for mankind to think of such a concept. At that time we would have also not thought of travelling through Airplane but in today’s time everything is possible. Space Travel is a wonderful concept which has given rise to the discoveries of our solar system. Now it is also possible for humans to send computers in space to study our universe. Landing on the moon was possible due to this. It was history created and a new step made by man. So, Space Travel is also an amazing concept turned reality in Physics.

 

4. Time Travel

This has not yet turned into reality but I think that in the near future it will be possible to travel through time too. Many scientists think that time travel will make humans lazy or will cause some disturbance but one thing is sure that time travel will be possible and no one can stop such a great concept to turn into reality. Stephen Hawking also has given so many concepts related to time travel. You can read his book ‘A Brief History of Time’ or even watch his ‘Into The Universe’ which frequently comes on Discovery Channel.

 

5. The Black Hole

I think this is one of the most wonderful concepts in Physics. It is a perfect example of a Perfectly Black Body. The compression caused creates a high gravitational field around the dead star so that light also cannot escape from it. Light has a tremendous speed of 3 X 10^8 m/s and if it can’t escape from a black hole then imagine about the power it has! I personally think that light is not the fastest. I have thought over it for quite a while now and I think I am right about my previous statement. Using the concept of black hole it is possible to time travel but only in the future. So, Black hole is also an amazing concept.

These are 5 of my favorite and amazing concepts in Physics. Do you have anything more to share?

Is speed of light the maximum one can achieve?

By: Nikhil Malankar

 

What is the first scientific thought in your mind whenever you see a light source or a light beam from any source? Whenever I see a light beam the first thought or question arises in my mind is how can light have such a tremendous speed? The second thought which usually comes in my mind is that if light has such a tremendous speed, then can anyone travel more than the speed of light? The whole article is based on the same concept. I always wanted to clarify this doubt about light. I may go wrong somewhere while writing some concepts. If you find any mistake then do let me know about the same through your comments. Let’s start with the discussion.

We all know that the speed of light is 670616629mph to be precise enough. Take a simple example to understand my concept. The example goes as follows: Suppose you are travelling in a car with a speed of 5m/s. Now you want to travel at 6m/s. So, you pump in more fuel to go a little faster with a speed of 6m/s. But is this possible if you were travelling in a shuttle which is able to travel at the speed of light? Take a simple example again. Example is: Suppose you are travelling in a shuttle which is travelling at 670616628mph. Now you pump in more fuel to travel at 670616629mph which is the speed of light. Now you are travelling at the speed of light. But now is it possible to go further than this speed? Or is the speed of light is just ‘THE’ ultimate speed in the universe? As the speed of light is a ‘physical thing’ we also can’t see of increasing or decreasing it. But is there anything else which can travel with a further speed? If it is then what is it? Let’s go into some further details.

Suppose if we are able to travel at a speed greater than 1mph than that of light. Now the question is that will it affect the shuttle? If the shuttle does not get affected then is there a possibility to go at a further speed? If the shuttle does not get affected then what is the maximum speed one can achieve? If light is the upper limit then why is it so? How does it charge the particles at such a fast rate? And if we are able to travel at a greater speed than that of light than what should we call it? Here I would also like to bring one of the existing concepts of ‘Black-hole’. Black hole is such a powerful thing that it can also attract light which is supposed to have maximum speed. So, if Black-hole can attract at such a great speed then can’t we artificially create such a great speed? If the concept of Black hole actually exists then it is also possible to create such a speed which is also able to attract light. According to the theory of relativity, a Black hole is a region of space from which nothing, even light, can escape.  It is called black because it absorbs the entire light incident on it and it reflects nothing. It is a perfectly black body. The life span of a Black hole is infinitesimal but it keeps on multiplying itself at a very high pace. Black hole is also very small in size. But as it keeps on multiplying itself it turns out into a huge mass which attracts anything and everything. So, can’t we use this concept to create an artificial speed which is actually greater than that of light? It would be an ultra speed to travel. How can we use this in day-to-day life? Let’s see further.

If we are able to get a speed higher than that of light then a whole new dimension would open up. We would be able to discover the universe and those hidden mysteries about so many things. So many unanswered questions would have a justified answer. It would also help for advancements in technology and we can also find out if aliens exist or not. If anyone arrives on any conclusions using this piece of information please do let me know. Thanks for reading this article.
