Theory of Relativity – A Brief History

The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time.

Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion.

This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed.

For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth.

Einstein also derived the famous equation, E = mc2, which reveals the equivalence of mass and energy.

When Einstein applied his theory to gravitational fields, he derived the "curved space-time continuum" which depicts the dimensions of space and time as a two-dimensional surface where massive objects create valleys and dips in the surface.

This aspect of relativity explained the phenomena of light bending around the sun, predicted black holes as well as the Cosmic Microwave Background Radiation (CMB) -- a discovery rendering fundamental anomalies in the classic Steady-State hypothesis.

For his work on relativity, the photoelectric effect and blackbody radiation, Einstein received the Nobel Prize in 1921.

Theory of Relativity – The Basics
Physicists usually dichotomize the Theory of Relativity into two parts.

·     The first is the Special Theory of Relativity, which essentially deals with the question of whether rest and motion are relative or absolute, and with the consequences of Einstein’s conjecture that they are relative.

·     The second is the General Theory of Relativity, which primarily applies to particles as they accelerate, particularly due to gravitation, and acts as a radical revision of Newton’s theory, predicting important new results for fast-moving and/or very massive bodies.

The General Theory of Relativity correctly reproduces all validated predictions of Newton’s theory, but expands on our understanding of some of the key principles.

Newtonian physics had previously hypothesised that gravity operated through empty space, but the theory lacked explanatory power as far as how the distance and mass of a given object could be transmitted through space.

General relativity irons out this paradox, for it shows that objects continue to move in a straight line in space-time, but we observe the motion as acceleration because of the curved nature of space-time.

Einstein’s theories of both special and general relativity have been confirmed to be accurate to a very high degree over recent years, and the data has been shown to corroborate many key predictions; the most famous being the solar eclipse of 1919 bearing testimony that the light of stars is indeed deflected by the sun as the light passes near the sun on its way to earth.

The total solar eclipse allowed astronomers to -- for the first time -- analyse starlight near the edge of the sun, which had been previously inaccessible to observers due to the intense brightness of the sun.

It also predicted the rate at which two neutron stars orbiting one another will move toward each other.

When this phenomenon was first documented, general relativity proved itself accurate to better than a trillionth of a percent precision, thus making it one of the best confirmed principles in all of physics.

Applying the principle of general relativity to our cosmos reveals that it is not static.

Edwin Hubble (1889-1953) demonstrated in 1928 that the Universe is expanding, showing beyond reasonable doubt that the Universe sprang into being a finite time ago.

The most common contemporary interpretation of this expansion is that this began to exist from the moment of the Big Bang some 13.7 billion years ago.

However this is not the only plausible cosmological model which exists in academia, and many creation physicists such as Russell Humphreys and John Hartnett have devised models operating with a biblical framework, which -- to date -- have withstood the test of criticism from the most vehement of opponents.

Theory of Relativity – A Testament to Creation
Using the observed cosmic expansion conjunctively with the general theory of relativity, we can infer from the data that the further back into time one looks, the universe ought to diminish in size accordingly.

However, this cannot be extrapolated indefinitely. The universe’s expansion helps us to appreciate the direction in which time flows.

This is referred to as the Cosmological arrow of time, and implies that the future is -- by definition -- the direction towards which the universe increases in size.

The expansion of the universe also gives rise to the second law of thermodynamics, which states that the overall entropy (or disorder) in the Universe can only increase with time because the amount of energy available for work deteriorates with time.

If the universe was eternal, therefore, the amount of usable energy available for work would have already been exhausted.

Hence it follows that at one point the entropy value was at absolute 0 (most ordered state at the moment of creation) and the entropy has been increasing ever since -- that is, the universe at one point was fully “wound up” and has been winding down ever since.

This has profound theological implications, for it shows that time itself is necessarily finite.

If the universe were eternal, the thermal energy in the universe would have been evenly distributed throughout the cosmos, leaving each region of the cosmos at uniform temperature (at very close to absolute 0), rendering no further work possible.

The General Theory of Relativity demonstrates that time is linked, or related, to matter and space, and thus the dimensions of time, space, and matter constitute what we would call a continuum.

They must come into being at precisely the same instant. Time itself cannot exist in the absence of matter and space.

From this, we can infer that the uncaused first cause must exist outside of the four dimensions of space and time, and possess eternal, personal, and intelligent qualities in order to possess the capabilities of intentionally space, matter -- and indeed even time itself -- into being.

Moreover, the very physical nature of time and space also suggest a Creator, for infinity and eternity must necessarily exist from a logical perspective.

The existence of time implies eternity (as time has a beginning and an end), and the existence of space implies infinity.

The very concepts of infinity and eternity infer a Creator because they find their very state of being in God, who transcends both and simply is.

We desire to help Radiate Jesus everywhere

We write compelling websites that reach out to skeptics, seekers, believers, and a hurting world with powerful evidence for God and the Good News of Jesus.

We believe truth transforms lives. Therefore, we place our content on the first few pages of the most popular search engines in the world. That way, when people seek answers on the Web, we're there with the truth at the top!

We are followers of Jesus. Like Jesus, we reject many of the issues found in “organized religion” (man-made attempts to reach God through rules and rituals). We consider the personal pursuit of God as paramount in each of our personal life journeys. We also believe that ultimate, saving Truth is found only through God’s Son, Jesus Christ. (Read our Faith Statement here.) We believe that the authoritative and primary source of that truth is the Bible as illuminated by the power of the Holy Spirit. Further, we believe that spiritual growth occurs in combination with being in God’s Word consistently and dealing with the things we suffer in this fallen world while being in fellowship with other believers where there is an atmosphere of grace, love, and accountability.

Although we're not formally affiliated with any organization or denomination, we work with a number of credible ministries and churches. Read what some of them are saying here.

AllAboutScience.org is a service of All About GOD Ministries, Inc, a 501(c)(3) Non-profit organization located in Belen, NM. Currently, we have a very small team and a much larger number of volunteers. Formal governance is maintained by an outside Board of Directors.

FASTER THAN THE SPEED OF LIGHT - If we can produce a propulsion system based on gravitational principles rather than electromagnetic or chemical ones, we could travel at absolutely enormous speeds - we could hope to push a space craft anywhere in the universe at warp speeds beyond what even the Starship Enterprise could produce! Newtonian mechanics imposes no maximum upper limit to attainable velocities in the universe, but Einstein's relativity theory does. Yet with God there are invariably hidden truths waiting to be discovered that make the best that men can imagine seem like kindergarten - we followers of Jesus the Lord may find ourselves capable of doing when we don our new resurrection bodies - these bodies are "not of this creation" - but spiritual bodies - The speed of a bullet is no big deal in these days of supersonic aircraft and spacecraft. Yet our fastest space vehicles do no better than one one-hundred thousandth of the current speed of light. Overcoming gravity (the weakest of all the forces of physics) still takes lots of push and power. The moon remains many days away and the planets many months when traveling as fast as current chemical rocket technology allows. The nearest star is 4 x 1017 meters away, and the current estimated size for the entire universe is greater than that by ten orders of magnitude or so (about 1026 meters). For a long time, the hope of space travel has been left almost entirely in the hands of the science fiction writers. As charged particles are pushed up near the present speed of light they grow heavier, and more and more energy input is required to gain a smaller and smaller increment of increased velocity.

Superman was able to leap tall buildings in a single bound, he was more powerful than a locomotive, and he was said to be able to travel faster than a speeding bullet.
The speed of a bullet is no big deal in these days of supersonic aircraft and spacecraft. Yet our fastest space vehicles do no better than one one-hundred thousandth of the current speed of light.
Overcoming gravity (the weakest of all the forces of physics) still takes lots of push and power.
The moon remains many days away and the planets many months when traveling as fast as current chemical rocket technology allows.
The nearest star is 4 x 1017 meters away, and the current estimated size for the entire universe is greater than that by ten orders of magnitude or so (about 1026 meters).
For a long time, the hope of space travel has been left almost entirely in the hands of the science fiction writers.
Yet with God there are invariably hidden truths waiting to be discovered that make the best that men can imagine seem like kindergarten.
Speed of Light May Not Be Constant, Physicists Say | Live ScienceNewtonian mechanics imposes no maximum upper limit to attainable velocities in the universe, but Einstein's relativity theory does.
As charged particles are pushed up near the present speed of light they grow heavier, and more and more energy input is required to gain a smaller and smaller increment of increased velocity.
At the Stanford Linear Accelerator (SLAC), near where I live, electrons injected in the accelerator reach 99.999% of the velocity of light in the first few feet of travel, and then they ride, traveling radio waves for two miles down a long evacuated pipe, gaining virtually no additional speed, but mostly acquiring mass (and therefore energy).
There is no reason to doubt the highly successful and well-verified theory of relativity in this regard. One can point to countless examples of proven relativistic effects whenever charged particles are involved.
Physicist Hal Puthoff has recently suggested that the ability of a spacecraft to modify the properties of space in its immediate vicinity could allow it to travel faster than light.
This is because the speed of light is simply a measure of two properties of the medium of space, or the vacuum: permeability and permittivity.
It has been tacitly assumed by some theoreticians that the speed of light might be a measure not only of the electrical properties of space, but the mechanical properties of space as well.
It now turns out that this is probably not the case!
A very exciting possibility has now come into the light.
It has long been known that gravitational forces apparently act instantaneously over the entire universe.
Why this should be so is simply glossed over and ignored in every generation of physics classes and in countless technical papers.
One way to understand this is to consider what is called "the classical aberration of light" - which was discovered by Bradley in 1728.
In fact, aberration data became one of the early methods for measuring the speed of light.
Light from the sun requires 8.3 minutes to travel from the sun to the earth during which time the sun and the earth have moved as much as 20 arc seconds with respect to each other.
Similarly, light from the stars arrives at an angle which can be as much as 20 arc seconds because the earth is moving with respect to the stars.
It is by carefully measuring these aberration angles, and knowing the relative velocities involved, that Bradley made excellent and trustworthy measurements of the velocity of light 250 years ago.
However, during the time interval it takes light to travel from the sun to the earth, the sun and the earth have kept in touch with each other "instantaneously" - or at least very much faster than c!
In fact, every mass in the universe communicates with all other masses in the universe in a time frame that makes the present speed of light seem like the velocity of molasses on a cold day!
Astronomer Tom Van Flandern has recently detailed all the evidence that shows that gravitational forces, unlike light, operate with no measurable aberration!
But Van Flandern shows that there are sound reasons for believing that the "speed of gravity" is not infinite.
By carefully studying the observable data, Van Flandern now concludes that the speed of gravity is greater than or equal to the present speed of light by a factor of 2 x 1010.
This velocity (6 x 1018 meters per second) turns out to be just below Barry Setterfield's latest estimate of the speed of light everywhere in the universe on Day Two of creation week!
Setterfield arrives at this initial velocity of light on the basis of the maximum observed Hubble constant, which gives an initial value of c that turns out to be 2.54 x 1010 times the present value.
Since creation week, the diameter of the universe has been constant (a static universe) and the speed of light has dropped precipitously to its present value-following decay curves we can now piece together with some confidence based on
(a) measured values of c for the last 300 years,
(b) corrections to known radioactive decay dates which go back to approximately 2000 B.C., and
(c) the observed quantization of the red shift of light from distant galaxies for the time period from creation to about the time of Abraham.
As the universe aged, the free space permittivity and permeability increased and c decreased - but the velocity of gravity may not be tied to the permittivity and permeability of free space!
If this is the case, the velocity of gravity stayed at the original velocity of c.
If we can produce a propulsion system based on gravitational principles rather than electromagnetic or chemical ones, we could travel at absolutely enormous speeds - we could hope to push a space craft anywhere in the universe, very literally at warp speeds beyond what even the Starship Enterprise could produce!
By the way, this discussion solely relates to the physical part of the created universe.
For now, we must defer discussion about how angels travel and communicate - they are spiritual beings.
And we must postpone speculation about what we followers of Jesus the Lord may find ourselves capable of doing when we don our new resurrection bodies (these bodies are, after all, "not of this creation" - but spiritual bodies - see 1 Corinthians 15).
If Van Flandern and Setterfield are correct, space travel may indeed be just around the corner!
A fringe benefit is that we may at last have clues to help us begin to understand the well-documented behavior of countless UFOs, whose velocity and acceleration behavior has thus far defied explanation by conventional physics.
