The Force Fields

There are four types of forces in the entire universe known to man: the gravitational force, the electromagnetic force, the strong and the weak nuclear forces. Imagine a fifth type of force, much stronger than the rest. It is called the force field. It is a thin sheet but invisible barrier that prevents any rockets or lasers to penetrate it. It is not that simple that someone scientist will announce that the force fields have been created. If we could build one then the army would have an impenetrable sheet or a barrier that will prevent any kind of missiles or bullets to penetrate. We could build skyscrapers taller than ever using this. The buildings built would be unharmed by the natural forces like the wind, storm and the rain. It could replace every building material. We could build huge architectural structure like flyovers, bridges, huge buildings in just a click of a button. We can even create cities under oceans, in deserts, or in any place we like. The force fields can create an absolute vacuum. It could be used to build the tunnel of the gravity train (refer to previous article) and keep the hot magma out.

Yet it is one of the most difficult things to create in a laboratory, some scientists say that it is almost impossible.

In 1995 a plasma window was created, something like the force fields. When we heat a solid we get a liquid, then a gas. If we superheat the gas what we get is plasma. A particular gas can be heated to create plasma then by using magnetic field t can be shaped according to our need. For example, a sheet or like a window. The plasma can keep out the air to create a complete vacuum. The plasma window created was no bigger than 3ft in diameter. Thus creating it in larger volume is quite difficult. The plasma window can keep down the pressure from all directions, in this case the air from the outside. Nowadays wielding is done by using acetylene gas which melts the wielding rods to join metals. But electron wielding is done in vacuum by firing electrons. It is a much cheaper and more efficient way. But it requires a vacuum. That is where force fields and plasma windows come in handy.

But why aren’t we building a plasma window when it’s already create in the lab?

Because it requires a lot of electricity to keep the temperature of the plasma to a certain degree. The electrical energy cost outruns the savings or the benefit we get from it. Thus it does not find any its place in practice. If we can somehow manage to get free electricity from a renewable source or in a very cheap price we can overcome architectural challenges in just a click of a button.

Creating a force field would make us invincible. It would make us much safer from the inter-galactic radiations. We can also be saved from the meteorites. No one ever imagined hundred years back that we could land on the moon…may be a few decades or a century later we can make nature dance to our tunes.

The Gravity Train

It takes twenty hours from Los Angeles to Beijing, eighteen hours from India to Australia, twenty one hours from Canada to Malaysia. But imagine going from any part of the earth to the other in just under an hour.

Is it really possible?

Well, on paper, very much. But in practice it has certain difficulties to overcome.

Imagine a train without fuel and travels much faster than anything in the planet. Imagine a gravity train. Let a tunnel dug through the core of the earth joining any two antipodal points on its surface. Let somehow we can suck out all the air to a complete vacuum to avoid any kind of friction by the air. If a body, in this case a transport is built which will travel through that tunnel, then it will take just over 42mins to get to any other point on the earth. The body will freefall due to gravity. It will accelerate till the centre of the earth. Just after crossing the core it will travel against the force of gravity so it will decelerate and stop just at the surface of the earth reaching its other surface. To make it a little bit simple let us suppose that we throw a ball upwards. The ball attains a certain height before falling to our hands. It will reach the ground with the same velocity we threw it. The same happens with the gravity train but let straighten out the path followed by the ball...and that is what we get as a gravity train.

But there are certain difficulties in building a gravity train. Firstly, digging through the earths mass will get more difficult as we move towards the core as the rocks will harden and will rise in temperature. To overcome this problem, we have come with a solution, if the tunnel be built, not through the core but like a chord in the circle. Then the travel distance would shorten but the time will remain exactly the same. Longer the distance faster we go. Ultimately it will take 42mins and 12secs. Secondly, at the core in melting heat and enormous pressure it is extremely difficult to keep the heat out and the pressure down. Very little construction material is available for these purposes which are too expensive to be used. Thirdly, making the whole tunnel vacuum is almost impossible. Due to less pressure in the inside and crushing force outside the tunnel will be crushed.

If some how with some special method or with some ingenious ideas we can make this possible……may be we would be having our breakfast in LA and lunch in Tokyo.

   The nearer we move towards the core the faster we will get.

The Big Bang and its after effects

Everything on the universe has to be born to live on it. Babies are born cute, pleasant and soft. But our universe was born in a little different way. It was the largest explosion ever recorded in all time. Just like the babies the universe was small, smaller than even a proton (a sub-atomic particle).

Time began with the beginning of the universe. If someone says that what was there before the Big Bang? Time started from it. The whole mass of the entire universe was concentrated in a mass no bigger than a proton. It was in a temperature of 10^{32 o}C. In one (trillion trillion trillion trillion)^th of a second the universe expanded rapidly with a huge explosion. The temperature dropped rapidly to 10^{27 o}C. Now the quarks (sub atomic particles) were formed. After a minute the light nuclei hydrogen, helium atoms were born. Time passed and newer atoms started to form. After 397,000 years the temperature stabilized to 2390K.The Universe was now somewhat stable. Shattering into a trillion pieces it made the galaxies (cluster of billion stars). Slowly and slowly the stars in the galaxies cooled and in a few million years formed planets. These planets took some another million years to solidify from a burning gas ball to a solid mass.

But in all the destructive explosions and vaporizing heat how was the delicate life created?

It is predicted that when the planets cooled down various protons, neutrons, electrons fused together to form different atoms. Nitrogen, hydrogen and oxygen, carbon etc. by random collisions formed different molecules. Amino acids were created: the carriers of life. That is the way some life like algae and some bacteria were created. Time to time the smaller species evolved and with mutations gave rise to the newer ones.

….this is the way we stand here. Our lives are hanging in a balance. A little change in our surrounding atmosphere may result in the loss of a billion lives.

In this destructive universe we are not alone…we are not the only one. It’s not we who are exploring it…

What will happen if we travel at the speed of light?

Is it really possible to travel at ht e speed of light?

How can we travel at the velocity of light?
Well, it requires a lot of energy and a constant force to keep a body accelerating. It has been found that the only possible source of this kind of energy may be the gravitational field of the Black Hole. It has the highest density ever known in the universe. It is so dense that even light cannot escape from it. That is why it is called 'Black'. The minimum velocity for a particle to break the earth's gravitational field is around 12km/sec. But for a black hole it is more than that of the velocity of light. Imagine you are standing on the black hole (which is not possible, as you would be vaporised) and you light a candle, you could see the light from the candle radiating out and coming down like a projectile. If a spaceship be built that can circle the black hole, then by using its cenrifeugal force one can slingshot at the velocity of light.

What will happen if we travel at the velocity of light?
Light, the fastest thing in the universe travels at a velocity of 186,000miles/sec or 3*10^8m/s. Time and velocity are very much related. Nature prevents us to travel faster than the speed of light. But if some kind of transport (for eg: a train) be built that will travel nearly at the speed of light we will be able to slow down time. It has been calculated, if one can travel at 90% velocity of light, one hour on earth will seen to be 2 in that transport. That is time will be halved. So we are travelling in time somehow. But let us consider this situation: a train that travels at 99.9999% velocity of light (if so, it would circle the earth 7 times a second) let a person run at a certain velocity on that train. Then the velocity of the person will add up. Then also the person cannot cross the light speed. In fact that person will slow down or will run in slow motion (to the observer only) which will prevent him from crossing the light barrier. The faster he wants to travel the slower he gets. If one can equal the velocity of light then time will stop for that person. If someone travels on that transport for a year, then he/she will go into the future without ageing. This is how time travel is possible.

Human being have broken the sound barrier much earlier. But can they overcome the light velocity?

Will time travel be possible?

Can we meet the people 500 years from now?

How space and time is related

This is approximately what you will see if you travel at light's speed
