2 Physics Theory That Don’t Work

January 12th, 2010

You might think physics is so useful, actually it’s not in real life situation. It is heavily researched but not as much as before, because lots of the findings just can’t be applied in real.


Theory #1 Force = Mass X Acceleration

It’s one of the most famous physics formula. Though it actually doesn’t mean anything. Friction just shatters this formula and makes it completely useless. It’s just impossible to calculate friction. If there was a variable for it, it would never be constant and nearly impossible to calculate. That’s why this formula is inaccurate and not used much in physics. Physicists do research on very small objects, such as atoms, in that scale friction doesn’t exist or is very small.

Theory #2 Light Speed

The speed of light is calculated to be 186,284 miles per second. Though this formula/ calculation has another variable to it. But normally there is something called air on it’s path. Einstein said that we should look at this theory assuming it’s in a vacuum. So basically the light that is traveling around you right now is not moving, exactly at the speed of light, probably a few miles slower.

What Makes Black Holes Exciting that Makes them Controversial?

March 16th, 2009

Black holes have been the subject of controversy over a long period of time dating back to history.  Black holes have been a part of Physics and the first person who predicted them was Laplace.  It was he who said that it may be possible that the biggest luminous object in the universe is invisible.

Black holes are luminous stars that have the same weight as the earth having the size of 250 times bigger than the sun.  Theoriticians have been trying to use mathematics of Black Holes to formulate solutions to a lot of mysteries on earth which remain a question until now such as the beginning of earth existence and the end of the universe, travel in time, etc.

What causes Black Holes to form?  The pressure created inside a star because its hydrogen fusion balances its gravitational attraction to its core, forms a star.  The amazing feature of a star is that it has its own system to exist and control all its powers and properties.  Since the hydrogen fusion and the gravitational pull balance each other, the star is able to maintain its size while hydrogen is active.

However, when the hydrogen has been transformed to helium, the existing pressure inside the star will lose its ability to balance with the gravitational attraction resulting to the decrease in its size.  This decrease in the size of the star causes its temperature to rise which results to the existence of the Fusion of Helium and the development of too much pressure.

In this case, the pressure becomes more than the gravitational attraction and this causes the star to expand.  This stage when the star has expanded is known as Red Giant stage.  This stage is followed by the depletion in the amount of helium that causes the star to contract.  Thus, it becomes a cycle.

There are 2 theories that may be involved in this cycle.  First, if the mass of the star is not enough to make another fusion, the star appears to be a white tiny star that radiates to release its internal energy.  Second, if the mass of the star dominates the whole body, then, the star turns into a contracted star.

In this process, a very powerful gravitational field is created that can control everything inside the star including its reflection of light outside its body.  This is the reason why its light cannot be fully seen on earth.  The process that the star impedes the ability of the light to travel outside is called Schwarzschild radius where kinetic energy of light is equal to gravitational potential energy of the contracted star.

Therefore above the radius, the gravitational field of the contracted star occurs and below the radius, light cannot escape the star.  This process where the light cannot go out from the interior of the star due to its strong gravity makes it invisible outside.  This is why we cannot fully see the lights of the stars, and this is the reason why they are called Black Holes.

The Amazing Invention of a Car Powered by Water

March 16th, 2009

Do you believe that a car will run if it is powered by ordinary water?  Your first impression will be negative because on a layman’s point of view, you know fully well that there has to be combustion to take place in the engine in order to make a car run and this is impossible for water to become an accessory to burning because in fact, it stops burning.

But of course if it is possible why not, it can be a great remedy for the world to substitute the high cost of using gasoline.

A car fueled by water was invented by a Filipino inventor, Daniel Dingel back in 1969.  A video presentation was shown in 2006 showing a car running filled with water which draws a huge crowd of stunned spectators who were amazed about the invention.

When asked how his invention works, Daniel Dingel revealed that the engine of the car has a compartment that induces water molecules to produce hydrogen.  He explained that electricity was utilized thru a 12-volt car battery to obtain hydrogen and oxygen by means of breaking up the water molecules.

The outcome of separating the water molecules produced hydrogen which is used to power the engine.  In his video presentation, Dingel failed to show a patent as proof of his invention.  This caused many experts in Science to raise doubts about the veracity of his invention.  Dingel also failed to show any technical paper in his video presentation, or offered an explanation to back-up his claim that a car powered by water will run.

Instead of explaining only the mechanics of his invention, Daniel Dingel should have also presented a technical paper outlining the theory behind his amazing invention.  What the public needed was transparency of proof thru a technical paper that can vouch for truth in his invention.

Scientists and experts who viewed his video presentation question the lack of scientific data to convince them that the invention is authentic.  Because of this, they come to believe that it is not water that powers the car but hydrogen.  Being the lightest form of chemical known on earth, hydrogen burns the same way as LPG and gasoline do that fuels the car to run.

In this process, hydrogen can be separated from water.  If you separate water into hydrogen and oxygen, you can produce hydrogen.  In this process, 2 water molecules can create 4 hydrogen atoms and 1 oxygen atom.  You can put water in the tank which will split into oxygen and hydrogen.

Then, the engine will be filled with hydrogen as in the case of gasoline.  The engine will make the car run by burning the hydrogen.  The waste emitted by the hydrogen-powered car is totally water vapor that is 100% sanitized.  The experts believed that Dingel used electrolysis procedure to separate the water into oxygen and hydrogen.

This becomes more doubtful because the stored energy in the car battery is very negligible to propel a car.  Hydrogen is not impossible to be used as car fuel, but it raises the doubts on practicality and safety in using it due to its very flammable condition.
