As stated by the relativity laws we are able to understand the relative motion of matter at higher velocities and the phenomena of length contraction and time dilation.
We have arguments stating these irregular behavior at incredible speeds. The theories put forward by many scientists just satisfy the particular need but it fails at some place and a new theory was laid to make up the gap.
Do you know the real thing? Our ancestors have made the background of Physics. It is really hard to imagine if they have made a little blunder that can collapse the entire World's scientific situation.
Remember the threat we felt when it was said the speed of light is decreasing. If so the things which we have developed with the help of light, by optics will be wrong. This change will affect the future to a great extent.
Our aim is try to find out the things behind each process. We are generally engaged in simplification of the process by reducing the constraints and approximating it to achieve at the result. Is it right to dedicate and neglect something as unwanted? You are ready to dedicate the size of an atom in the manufacturing of a steel rule. By Physics we are now in the position to measure the size of unknown things which are believed to be present in an atom. With this principle anyone is ready to build a scale by arranging those metal atoms one by one so as to achieve the right dimension.
This will be totally absurd thing to think of. Do you?
Once upon a time it is very difficult to throw a stone to a few hundred meters. But now we have developed instruments that have the capability to throw tonnes of weight into the outer space.
The background is the growth of Physics.
By going to observe the things of nature wh...

It is not possible for us to control the green house gas emissions and to stop the drastic changes that we are making to Earth then it is a waste to think about the "Great Future."
Human is generally not concerned about the numbers(which is used as dollars, Dinars, etc) and length, mass very much. Everything which we describe as science is the thing for existence. You can feel the worth of water when you are in deadly dry desert. At the greater heights of Everest pure water will be available in the form of ice. But it is not the fact that you can travel without water.
The things in the right form will work. Everyone is not ready to lead an adventurous life. So we are in the situation to form Physics with fourth dimension "human behavior" as the base and not alone with numerals.
Natural gas, Priuses, LEDs, hydropower, solar power, burning trash, or improving traffic is not the answer to becoming a green nation. People need to change their behavior in order to change their actions; everyone must take a stand and use cars less, use less electricity, and use less of everything, because less is enough. If we wish to discourage society from using excess energy there needs to be an increase in: prices of oil, electricity, worsened traffic, and denser city populations. There is a way to do this without having the populace revolt: increase the prices of these services or goods nevertheless offering a modest stipend for those who decrease usage. If we truly want to live on Earth for a prolonged period of time, then we need to take care of her but are we willing to change our consumer mentality for the future of our
Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought resistant crops.
Einstein’s Special Theory of Relativity has had a colossal impact on the world and is the accepted physical theory reg...
It is possible that this technology will be explored and improved further with the growing emphasis on energy efficiency. In 1915, he introduced his general theory of relativity, expanding on the special theory of relativity. This theory proved certain relationships between masses, space, and time, significantly influencing the later development of the GPS system, which is now a staple of everyday life.
Since the beginning of time itself, man has been dreaming of time travel. The current model of physics shows no obvious doubts towards the possibility of time travel, which leaves many questions (“Quantum Time Travel”). If the quarrel for time travel holds any truth, how will man manifest the means of going about it? Before the theories set forth by the men and women in the scientific community can be understood, one must have at least a general knowledge of the basics behind quantum mechanics, as well as the estimable; Einstein’s, theory of space-time. Also, in a world where time travel occurs, there is the possibility of a paradox, or impossible situation caused by the travelers’ actions. Many answers to the paradoxes have been set forth by notable people. Possibly the most widely accepted theory of time travel, Einstein’s black hole theory, still holds prevalence to this day. Some other theories have come to light recently, and most are yet to be disproved.
Finally, length contraction is apparent whenever an object is in motion. For instance, an observer on the Earth would measure the length of the rocket to be shorter when it is moving at its high speed as compared to its length at rest.
This numbness is natural, stemming from the fact that humans simply do not deal with such numbers very often, and even when they are dealt with, they are seen as words, not rational concepts. The fact that absolutely everyone suffers from this difficulty could prove to be harmful in the future, as population grows at the seemingly infinitesimal rate of 2% per year, an amount that is actually quite large when the current number of people on Earth i...
People are familiar with measuring things in the macroscopic world around them. Someone pulls out a tape measure and determines the length of a table. A state trooper aims his radar gun at a car and knows what direction the car is traveling, as well as how fast. They get the information they want and don't worry whether the measurement itself has changed what they were measuring. After all, what would be the sense in determining that a table is 80 cm long if the very act of measuring it changed its length!
Particle Physics plays an important role in attempting to answer many modern cosmological theories, notably: dark matter, structure formation, baryogenesis and nucleosynthesis. I am going to discuss some of connections between particle physics and cosmology and investigate how experimental particle physics and cosmology can complement each other and how dependable the connections are.
In The Quantum Enigma, Rosenblum and Kuttner address the impact of the “Newtonian worldview” on our ability to understand and explain the phenomena of the physical world. Science has been able to greatly advance our knowledge of the natural world over the last several centuries largely due to this worldview. In this paper, five tenets of the Newtonian worldview will be summarized; two of these points—those found to be the most and least defensible—will be discussed in greater detail. As a final point, a discussion will be laid out regarding which of the five precepts, if rejected by modern physics, would be the most disturbing to give up.
...pecial relativity has caused profound changes in the way we view our universe at its most fundamental level. The theory has had an effect on many areas of science, especially physics. Even though many people did not think that special relativity was anything more than a theoretical idea, it has been tested numerous times. In every case, the predictions of special relativity are upheld. Special relativity is a cornerstone upon which modern physics has been built, and it is one of the greatest discoveries of the twentieth century.
Don’t you want the trash cleaned up to enjoy nature? Don’t you want the water clean for you to drink? And don’t you want to see the skies clear and blue all the time? If we don’t act now, there might not be a world to save. Go green for the sake of the future.
I am not saying that Newton’s and other theories like it are wrong, I am saying that we put too much faith in something that is not absolute, unfortunately we have no other choice.
One of the most talked about subjects on the future is climate. At this very moment the Earth is warming up and we are the cause. The warming of the Earth is known more commonly as global warming. Maybe this subject is going to be fought over for centuries while we squander the time we have left away, but even if we did stop doing the things that cause global warming it will not bring it to a standstill. The main cause is pollution, and although scientists say that crude oil will be a thing of the past, alternatives to it will be created.
Since the days of Newton, the ideas of classical mechanics prevailed in the scientific community. The ideas of absolute velocity and absolute time were accepted phenomenon and were not at all challenged. However, as the nineteenth century drew to a close, new observations were being made, observations which contradicted the current theory of the time.
