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.

The Universe according to Me

:Posted by Gaurav

All the theoretical physicists around the world are looking for the Grand Unification Theory. A theory that incorporates everything in the universe including the universe itself. The four forces in nature are all that make up this universe or rather I should say that universe which can be observed. Definitely we haven’t seen the edge. Neither we have found any center. On the other hand our universe is so big that by laws of mathematics, which we have devised, we are at the center.

Thus all the theories and the calculations we have done cannot be imposed on that part of the universe that we haven’t observed. We may ourselves be an exceptional part in the universe where the value of Planck’s constant is what it is. This is pure imagination but, according to quantum physics, a valid one. The constant will have multiple Eigen value states until and unless it is actually observed. So there is always a possibility that we would not be able to imagine what is beyond the observable boundaries like the experiment with Schrodinger’s cat.

So here’s, what I should say, an extended version of what you all know.

The Universe according to me is designed in three basic simple steps. These are :

1) Initiation

2) Chaos

3) Re-Order

Everything that we see is a result of some kind of initiation. This may be somewhat opposite thought to those who believe in coincidences. But actually, if observed carefully, coincidences are merely the happening of two or more events simultaneously. It is the nature of human mind to find the relation between two events that it observes simultaneously.

Consider a small accident happening. A car hits a truck and loses its rear view mirror. Obviously, the two drivers first come out to check the damage, if any done, to their respective vehicles. The car driver sees that he has lost a rear view mirror and starts yelling at the truck driver. The truck driver doesn’t thinks that it was his mistake. The observers around see the broken mirror and start creating their views about the accident. Each of them has a different theory. Some would say that the truck should have stopped because there was traffic. Some would say the car was speeding and they thank God that no one is hurt. Some would say the car driver is drunk and that’s why he is wasting his time and energy for such a small damage what could have been a big one. Some would say it was just a coincidence.

There can be a correct theory. But the coincidence is that the car and the truck came in contact with each other. So the observers make their theories and name them as coincidences. For eg. An observer who observed the car before collision would say that the car driver is to blame that he was speeding. It was a coincidence that the truck took the car’s rear view mirror.

Hence, everything has an initiation, we just name it coincidence.

Then comes Chaos.

The world has been chaotic in some or the other point in time. Consider the above example again. The car hits the truck. So everything around it changes. If the car had not hit the truck, everyone would continue their work as planned. The truck would have safely crossed a road. The drivers would not have got out of their vehicles. All the observing people would not be observers at all. Of course I am taking the collision as the initiation. The initiation was followed by the chaos by the immediately above assumptions not happening. Everyone came out of the order they were meant to remain in.

And then comes Re-Order.

In the same example, eventually everyone has to go to work or home or any place they want to. So they move away from the site of accident. The two drivers take their vehicles out of the way due to honking of oncoming traffic and the road becomes busy again. But here the order is created due to initiation of some other kind(like the honking).

Hence if observed carefully, everything in the world has an initiation and then go into chaos and then reorder. This was also happening at the time the ‘ Time ‘ started. And it is happening to this very day. The chaos and the reorder become the initiation of other processes thus making the nested cycle of themselves.

My views on the Universe : Part 3

This article is the 3rd part of the series ‘My views on the Universe’. The first part was.  My Views on the Universe : Part One and the second was My Views on The Universe : Part Two. So, I recommend you to first read the 1st part and 2nd part and then come to this 3rd part. Let me introduce you again to this series. This series is my imagination about how the universe actually is. So, without wasting much time let me start off with the topic.

This 3rd article is based on an assumption that the Universe is just a sheet of paper. Paper? How? Okay! Let me express myself. Read on.

Imagine that the Universe is just a paper. Paper has many uses and mostly it is used for writing and drawing. So, imagine that the Universe is sketched on a piece of paper. All the planets, meteoroids, stars, etc. are just drawings! This piece of paper is not too big but is very detailed. It has been sketched using a very fine pencil. Or should I say a rainbow pencil which adds a mixture of all the beautiful seven colors and their shades into this Universe. So, why does the Universe appear to be black? The answer is because most of the part is not colored yet J. It takes a lot of time to detail everything and so the artist of our Universe has decided to give colors only to the part which are important. The specialty of His art is that this paper turns its drawings to life within itself! And that’s why we have various life forms. But only those life forms exist which the artist has written at the back of the paper.

So, there is a 100% possibility that aliens exist. This artist has created only our Universe. There are many other artists who have sketched their imagination into their papers and created many Universes which can also be termed as parallel universes. One more thing is that this artist is never satisfied with is work and so he is always creating a new imagination and adding it to our Universe. So, our Universe is ever expanding.

We should praise the intellect of this artist who has created such a wonderful world! And we can learn an important lesson from his artist that ‘Never be satisfied! Satisfaction leads to rest and rest will never fetch you rewards’. So, keep on working and adding new feathers to your hat. And one day you will have your world as the Universe itself!

So, this was my 3rd part. Hope you liked it. In case you did not read my first 2 parts then their links are:

My views on the Universe : Part 2

By: Nikhil Malankar

 

This article is the 2nd part of the series ‘My views on the Universe’. The first part was.  My Views on the Universe : Part One. So, I recommend you to first read the 1st part and then come to this 2nd part. Let me introduce you again to this series. This series is my imagination about how the universe actually is. So, without wasting much time let me start off with the topic.

My 2nd part of this series is based on an assumption that the Universe is The Internet! Interesting imagination, isn’t it? Now let’s correlate both of them.

Nobody of us knows that how big the Universe actually is. Whereas we do know how big the Internet is but still we can’t say definitely how big it is. The internet goes on expanding every hour, every minute, every second and every nanosecond because it is being continuously used by people worldwide. Many scientists say that the Universe also goes on expanding continuously. Just imagine that the Universe is The Internet.

Based on these assumptions we can say that the Universe has a definite size at a particular instant of time. But the size goes on increasing every moment. The same is with the Internet. Now here I would like to make a very bold statement. It is said that the Internet’s size doubles every 5.32 years and so the size of the Universe also doubles after a particular time. The time cannot be determined by us because we ourselves are a part of this big, wide network of Internet. Our Internet is comprised of many other things too! You can call them void spaces, trash, asteroids, etc. They are Flash programs. And as we know that the Internet is an open source of information so anyone can edit a part of the Internet. So, the story of our planet Earth is published on some website and accordingly everything is happening. The story is minutely detailed by a very good writer. So, you can imagine that the story of Earth is only a single webpage which has a finite start and a finite end. Every single detail from the formation of Earth to the last second of destruction of Earth is written in a detailed way with stories of our lives, etc. And now just imagine that if the story of our Earth is only a single webpage then what about the other planets, asteroids, black holes, etc.? Now you have to realize that the Universe is really very big and ever expanding and so we can say that if the Universe is The Internet then the information goes on increasing. That is, a new story is published every second! The story of other planets, aliens and every other thing in the Universe is written and published with all the details. If the link to this information is added to our Earth’s website then we come to know about them otherwise the story goes on.

And then as we know that there is no end for the Internet as it is ever-increasing. The information posted on the Internet (i.e. The Universe) cannot be changed! This means that the past cannot be changed. The only thing that can be done is to create a future. And I hope that whoever is the writer of Earth’s story has given it a beautiful future. Whatever has happened let it be. We can only hope for the future to be as good as possible.

So, this is the 2nd part of my imagination. Read more in the 3rd part or just have a look at the 1st part in case you have not read it yet. Click here to read the first part My Views on The Universe : Part One

My views on The Universe : Part 1

By: Nikhil Malankar

 

‘Universe’ is indeed very big and nobody knows exactly how big it is. I was just thinking about the same and then came across some amazing and interesting theories. So, I present you the ‘My views on The Universe’ series where I will tell you what I thought. Here is the first part of the same.

Okay! So, my first part is based on an assumption that the whole Universe is a game controlled by a computer. And there are many such games, i.e. there are many universes. So, if there is a computer then naturally someone has to control it. And that controller is the user of the computer. Now you can call that user ‘God’, super power, Supreme Intelligence or anything you want. This user has designed our universe and is controlling it on every step.

The Universe is very big for us but to the user it is finite. All the solar systems, galaxies, stars, etc. are small-small programs. You can consider them as mini games created by the user. And then we have the planets as the main part of the game where everything takes place from evolution of life to destruction of the same. The main part lies here! The user has programmed the life on planets in a very interesting way. He has also designed so-called ‘Aliens’. And to us Aliens are out of reach because the user has not given us enough privileges to discover them yet. May be if he desires to change our attributes then we will be able to reach the aliens. Each and everything is minutely detailed using the most complex physics calculations and the best game engine with the best computer processor. There are yet many things for us to discover which are given ‘hidden’ attributes. When the user will remove the attribute we will discover those facts and things.

The best creation of that user is ‘human’. He has given humans the most important and beautiful gift of intelligence with speech. Now you have to realize that speech without intelligence and intelligence without speech are useless! So, it is a plus point for humans.

The most interesting part comes now! Okay! So, we are a part of this game called The Universe. It is obvious that the characters in any game don’t know who their user is because they are designed to only think about the story of the game and they only do the work for which they are programmed. The same applies to us. If we are a part of this game then we, too, don’t know who is using us. But there is some user who is sitting there and controlling us. He is even updating, upgrading, fixing glitches of the game. The programming of the game is so good that it does not crash and if it does then it can cause havoc in the entire Universe.

The story of Universe is already decided and it is up to the user of the computer to lead it. So, the end of the Sun, Earth and various other planets can be a mission for the user. Sounds interesting, right? And then discovery of life of other planets also are missions.

Actually the game never ends. There is a lot of customization involved in it and can last till infinity if the user wants or he can simply delete the game. This can be related to the GTA series. The GTA series also does not end after all missions are complete. Instead we are free to roam around and do whatever we want. Same is with this Universe. It is up to the user.

So, this is the 1st part of my imagination. There is more to this series and I will post more parts soon. Till then just keep imagining what the next part will be about. Have a nice day!
