velocity Archives - DOES GOD EXIST? TODAY

Being Timeless Being outside of time or timeless is a new concept to science. In classical physics, time is perhaps the most fundamental standard against which everything else is based. When we measure velocity, it’s basic unit is length per second or hour. Feet per second or miles per hour are familiar to most of us. When we measure acceleration, the units are meters per second squared. Newton’s Second Law defines force as mass multiplied by acceleration, so time even becomes involved in parameters that don’t directly include motion.

One of the equations that Einstein gave us which high school students like to play with is the equation for time at very high speeds. For a given frame of reference, time is defined by the equation T = T’/the square root of 1 – V² over C². In the equation, T = the time you experience. T’ is the time you would experience at rest relative to a given frame of reference. V is the speed at which you move, and C is the speed of light. Notice that as your speed reaches the speed of light, the fraction V²/C² become 1, and since it is subtracted from 1, the value of the denominator becomes zero. Time ceases to exist. It becomes undefined.

If you could exceed the speed of light, the denominator would become the square root of a negative number which is said to be imaginary. Einstein gave us a similar equation for mass in which the mass is the undefined factor. Nuclear physics and quantum mechanics verify these equations.

This is an over-simplified explanation, but the point I am making is that there is physical evidence that there are dimensions beyond the three in which we exist. Being timeless is something science has begun to comprehend because these equations show that time is a variable that can be changed. The creation is far grander and far more mysterious than we can imagine.

For Christians, this is no surprise. The Bible is full of descriptions that embrace the idea that time is a created entity and that creations exist outside of time. The whole concept of there being a beginning to the cosmos in Genesis 1:1 recognizes that there was an existence before time. Proverbs 8:22-23 indicates that time was a designed and fashioned quantity. Revelation 22:13 repeats this concept. Second Timothy 1:9 refers to it, and the whole idea of eternity relies upon it.

When we reach the end of life, time ceases to exist for us. That has interesting implications. If there is no time, there is no death because death depends upon aging, and without time, nothing ages. There is no physical pain if time doesn’t exist. That’s because physical pain depends upon the time it takes for the pain signal to go from what gets hurt (like a finger) to what registers the hurt – your brain.

“No more tears, no more sorrows.” Revelation 21:4 Describes this change saying that “the former things have all passed away.” Second Peter 3:8-13 speaks of the elements dissolving at the end of time. Science has given us some reinforcement for these promises recognizing that the physical world will be done away with when time ends. Let us live in such a way that we can look forward to the timeless new order God has in store for us.

As an old physics teacher, I find it interesting to watch people on both sides of the argument about the existence of God pick and choose various parts of Einstein’s work to support their positions. Picking and choosing Einstein to prove your point is not an option.

Recently I had an atheist and a Christian dispensationalist both use Einstein’s time dilation equation to support their position. That equation says that your time in motion is determined by your time at rest divided by the square root of one minus your velocity (v) squared divided by the speed of light (c) squared.

This formula indicates that the higher the velocity of motion, the smaller the value of the denominator of that equation becomes. Therefore, time expands. This is a fact. Neutrons in nuclear accelerators might live 18 minutes at rest before decaying into protons and electrons. When accelerated to 80% of the speed of light, they last much longer before decaying.

My atheist friend maintains that since the cosmos is accelerating in its expansion, it will eventually reach the speed of light and time will stop. He then proposes that time will reverse since the value of the denominator in Einstein’s equation would become negative. He then suggests that this process will be repeated in an eternal universe. Therefore, no beginning and no God.

My dispensationalist friend is one of several authors who propose that the universe started out expanding at a much higher velocity with time passing at a different rate than we experience today. This would mean that the evidence for the cosmos being very old is an illusion. In the beginning, time passed more slowly because of the much higher velocity of expansion. Since we move more slowly today, time is passing faster. Therefore, the universe is much younger than it would appear.

Both of these people were picking and choosing Einstein to support a personal religious opinion. Both of them are ignoring much of Einstein’s work. When the neutron referred to earlier is accelerated to 80% of the speed of light, not only does its time frame change but its relativistic mass changes too. Another one of Einstein’s equations looks just like the time equation but deals with mass. The change in the relativistic mass of a particle is equal to its mass at rest divided by the square root of one minus its velocity squared divided by the speed of light squared.

Experimentally this calculation works and can be verified. Perhaps the most well-known equation of Issac Newton is F = MA. This tells us that the force (F) needed to accelerate a mass (M) is equal to its mass multiplied by the acceleration (A). We all know from experience that the greater the mass of an object, the harder it is to speed it up when we push it, and the faster we want it to go the harder we have to push. If the relativistic mass increases as you get near the speed of light, what happens to the force you have to exert? Obviously, It increases too. At the speed of light, you would have infinite mass, and it would take an infinite force to move it.

Another fascinating equation from Einstein is that the length of an object changes as it approaches the speed of light. In the reverse of the change in time and mass, the length contracts in the direction of motion as the object gets closer the speed of light. At the speed of light, the length would be zero, and the object would cease to exist.

These are simplifications of Einstein’s work, but the point is that picking and choosing Einstein to prove your point is not honest. Relativistic effects cannot be picked and chosen while ignoring other effects. God created the cosmos with certain constants and relationships. These choices allow us to exist, but they also put a limit on what is possible. We struggle to comprehend all that is involved in the simple phrase, “In the beginning, God created the heavens and the earth.”
