Faster then the Speed of Light "The Dark Energy"

The Dark Energy

According to Albert Einstein "Nothing can surpass the speed of light" but as you know  is full of exceptions there is one thing which have surpass the speed of light and which is The Dark Energy.

so basically the Dark Energy is  the energy which is responsible for the expansion of the universe.

let me give you an example our universe is about 13.7 billion years old suppose if the rate of expansion of universe was even equal to the speed of light the universe will be about 13.7 billion light years in size but the real size of universe is about 28 billion parsecs or 93 billion light years which clearly shows that the rate of expansion of universe was even faster then the speed of light at a particular time.By this concepts the scientist are believing on a technique of "Warp Drive" which can be a way to travel faster then light.well now the rate is about 68 km/sec.so lets take a close look at the topic "Expansion of universe".

Expansion of universe:

The expansion of the universe is an increase in the distance between the two remote parts of the universe over time. It is an internal detail that changes the level of space. The universe does not "extend" in anything and does not need to be "out" in existence. Technically, neither the space nor the objects in space space. Instead it is a metric that controls the size and geometry of spacetime, which changes on a scale. Although light and objects within spacetime can not travel faster than the speed of light, this limit does not limit the metric. The observer feels that space is increasing and nearby galaxies are decreasing at all distances.

During the Big Bang, during the 10-32 of a second during the inflationary period, the universe suddenly expanded, and its volume grew at least by 1078 (the distance of the distance by at least 1026 factors in each of the three dimensions ), An object is equal to extending 1 nanometer (10-9 m, approximately half the width of the DNA molecule), approximately 10.6 light years (approximately 1017 meters or 62 trillion miles) long. After about 9.8 billion years of the Big Bang (4 billion years ago), the space continued to slow and slowly, it gradually began to grow, and it continues to do so today.

The metric expansion of space is completely different from the expansion and explosions seen in the daily life. It appears to be entirely a property of the universe rather than a property of the universe, which applies only to one part of the universe or it can be seen from "outside".

Metric expansion is a major feature of the Big Bang universe, which is mathematically modeled with the Friedman-Lemière-Robertson-Walker metric, and it is a common property of the universe in which we live. However, the model is only valid on a large scale (almost on galaxy clusters and above scale), because gravitational attraction strongly connects the fact that metric expansion can not be seen at a small scale at this time. Thus, the only galaxies emerging from each other as a result of metric expansion are largely different from the scale related to the universe relative to the length associated with the possible gravity collapse in the age of the universe, which see the case density and the average expansion rate. .

Physicists have given rise to the existence of dark energy seen in the form of cosmic stability in the simplest gravitational model as a way to explain acceleration. According to the most recent extrapolation of the currently preferred universe model, Lambda-CDM model, this acceleration becomes more effective in the future. In June 2016, NASA and ESA scientists reported that on the basis of studies using the Hubble Space Telescope, the universe was accelerating from 5% to 9% with first thought.

While special relativity prevents objects from moving faster than light in relation to the local reference frame, where space time can be considered flat and irreversible, it does not apply to situations where space-time curvature or development becomes important at times is. These conditions are described by general relativity, which allow for separation between two remote objects to grow faster at the speed of light, although the definition of "separation" is used in a root frame. This can be seen by looking at galaxies far away from the Hubble radius (about 4.5 gigapars or 14.7 billion light-years); These galaxies have a slowdown speed which is faster than the speed of light. The light emitted today from galaxies beyond the cosmic event horizon, about 5 gigapars or 16 billion light-years, will never reach us, although we can still see the light that these galaxies were emitted in the past. Due to the high rate of expansion, multiplying the speed of light from the age of the universe is also possible for the distance between two times the calculated value. These details are a frequent source of confusion between amateur and even professional physicists. The non-intuitive nature of this subject and some people have been described as "carefree" choices of words, some details of the metric expansion of space and misconceptions for which such details can lead, discussion within education Is a continuous topic and communication of scientific concepts.

Warp Drive:

A Warp Drive is the most famous fast-to-light (FTL) spacecraft propulsion system in the works of many science fiction, especially Star Trek. A spacecraft equipped with a warp drive can travel more speed than light with many orders of magnitude. Unlike some other fictional FTL technologies, such as jump drive or hyperdriver, the warp drive does not permit immediate travel between two points, but it includes a scalable path of time according to the concept. On the vapor velocity, the space shuttle will continue to interact with objects in "normal space". The general concept of "Warp Drive" was introduced by John Wood Campbell in the 1931.

The principle of Einstein's special relativity states that energy and mass can change between each other, and the speed of light objects is impossible for physical objects that weigh more than the photon. The problem of material object more than the speed of light is that in order to travel at the speed of light, infinite quantities of dynamic energy will be required. It can theoretically be solved by moving the space to move the object instead of increasing the dynamic energy of the object. For the speed of light travel, such a solution leads to two straight opposite approaches to light motion travel in science fiction: First, the space shuttle itself is brought to light speed and further; Secondly, for the arrival of the ship, the local place itself is made to come in the ship itself, while the ship runs on the sub-light speed.

There are even more ways to travel faster then light but we will talk about them later in another blog.but till then let us know do you believe in FTZ in the comment section below and if you like this topic do follow my blog for more amazing topics till then have a great day ahead.

Peace:-)
