Einstein's General Relativity and Einstein's Special Relativity
Not many understand the vast and important implications of Einstein's General Relativity and Special Relativity. Nor do many know that these two theories should be called laws, as they have been tested and proven beyond any reasonable doubt to be 100% true. Both are the most tested and proven theories.
Einstein's General Relativity: Einstein's General Relativity is the theory of gravity that describes gravity not as a force, but as a curvature of spacetime (the fabric of space and time) caused by mass and energy, dictating how objects move. Tests have proven the theory. It shows that objects—from planets to light—follow curved paths in this distorted spacetime, providing a more accurate description of gravity than Newtonian physics. It also shows that gravity is locally equivalent to acceleration. A person in a rocket accelerating at 9.8 m/s^2 feels the same force as someone standing on Earth. Gravity bends the path of light (gravitational lensing) and slows the passage of time (gravitational time dilation).
Einstein's Special Relativity: Einstein's theory of special relativity united space and time, stating that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum is constant for everyone. This includes: E = mc^2, Energy = Mass × Speed of Light squared. Also, time and space are relative, not absolute, resulting in time dilation, length contraction, (Time passes more slowly for an object moving at high speed compared to a stationary observer). The laws of physics are identical for all observers in inertial frames of reference (moving at a constant velocity, not accelerating). No particle with mass (or object) can reach the speed of light because it would require infinite energy.
E = mc^2 shows that the speed of light is a constant in the universe; if C, the speed of light, changed at all from its 186,000 miles per second speed, stars would not burn the same. This would mean there would be no possibility of life anywhere in the universe at any time in the universe.
The proven Space-time theorem uses the theory of general relativity.
Space-time theorem establishes that a Causal Agent beyond space and time created the space-time dimensions of the universe. This statement is true if:
If the universe has mass (it does) and
The universe is expanding (it is) and
The theory of general relativity is true. (it has been proven beyond any reasonable doubt.
One of the authors of these theorems, Alexander Vilenkin, wrote: “With the proof now in place, cosmologists can no longer hide behind the possibility of a past eternal universe. There is no escape, they have to face the problem of a cosmic beginning.”
The "problem" Alexander Vilenkin is writing about is only a problem for those who do not like that study of the universe as us to the same place that the Bible stated 3,500 years ago. Gen 1:1 In the beginning God created the heavens and the earth. Biblical Hebrew always uses the phrase " heaven and earth" to describe the entire universe: all space, time, and matter. This includes the Sun, which was not created later. The Bible has more to say about the beginning of the universe, Titus 1:2, and 2 Timothy 1:9, (2,000 years ago) tells us that Time had a beginning, just as the Space-time theorem states. The mathematics has been done, the Space-time theorem has passed the test. Only the God of the Bible is described as being extra-dimensional.
The Bible:
1) Gen 1, Psalm 148:5; Isaiah 40:26; 42:5; 45:18, Titus 1:2, and 2 Timothy 1:9, the universe (time, space, and matter) had a beginning; this is correct.
2) The universe has been expanding since its creation. See verses: Job 9:8; Psalm 104:2; Isaiah 40:22; 42:5; 44:24; 45:12; 48:13; 51:13; Jeremiah 10:12; 51:15; and Zechariah 12:1. These five different Bible authors all stated that the "stretched out" of the "heavens" or "skies" meaning outer space, is ongoing. Job 9:8; Isaiah 44:24; and 45:12 state that God alone is responsible for the cosmic stretching.
3) One of Christianity’s foundational creeds. Creation ex nihilo (Latin for “creation from nothing”) refers to the moment God created the universe from nothing (that which lacks matter, energy, space, and time). The Bible states that creation ex nihilo in Genesis, but Hebrews 11:3 states it explicitly, “The universe was framed by God’s command, so that what is seen was not made out of what was visible.”
The above is why you will still find some people foolishly attacking Einstein's General Relativity and Special Relativity.
