Albert Einstein's special theory relativity. Ligh speed velocity time


Albert Einstein's special theory relativity projects points of view we observe time on a light speed scale. For example arithmetic  tells us from our point of view light travels 7 times round the entire circumference of earth the same time we walk a meter equivalent to 300,000km ( 299, 792km and 458 meters to be exact or 186,000 miles if you like ).

It is the time we take a couple of strides saying one thousand and one. It is the same amount of time we finish half this sentence, the same amount of time analogue clocks and watch second hands move a division and the same amount time digital time pieces take to change each second. All a second of time equals a light second the distance light travels in a second. You do the math's.

Text books tell us light takes 8 minuets to reach earth from the sun. If we do the math's on this sunlight from the sun right now is an nothing more than an image of the the sun as it was eight minutes ago every second. We won't observe the sunlight leaving the sun in real time moment until eight minutes into the future. This tells us the sunlight we see every second of real time to us is only relative to the time it left the sun in a factor of minutes.

Since light travels at a 300,000km/s velocity mathematics tells us it travels a distance of 300,000km increments every second. Our mathematical instinct agrees if we add up all the seconds in 8 minutes multiplied by the speed of light in km or miles gives us the distance earth is from the sun equal to the distance light travels in eight minutes. Light is  300,000km above the sun's surface by the time you finish this sentence. 

Consequently when the light reaches our eyes in eight minutes time the sunlight will equally by 300,000km away away from earth. Consequently we are observing sunlight eight minutes old from the sun 300,000km away every second getting father and further away by every 300,000km increments every second. The math's tells us light is a continues uninterrupted flow.

From our point of view light reflects off the moon's surface to our eyes in less than couple of seconds. The same can be true from the moon's point of view of light reflected from earth. Taking 8 minutes to reach our eyes from the sun, the sun is the nearest star only a mere 8 light minutes away. If we go by the numbers on this tells tells us each planet is mere light hours, and light days from earth.

The end of the solar system pans out to be light some weeks away. The arithmetic tells us the sunlight we saw in real time on earth a year ago is now the distance light had traveled in that time away from us in some distant corner of the universe continuing to add 300,000km every second of our lives.

Our mathematical instinct agrees it is only a mater of multiplying sixty seconds in a minute, by sixty seconds in an hour ( in other words sixty squared ) multiplied by the 24 hours of our day, multiplied by 365 days of the year equals adding up all the seconds of year every second 300,000km equals the distance light traveled in that time.  Of course compensating for a leap year is 257.

Einstein tells us traveling at any velocity is the same amount of time, For example if we were at light speed time to us will be normal seconds, minutes, hours and days of travel to the end of the solar system. But we view the universe slowed down by the equal amount light as fast panning out to be 300,000 times as slow relative to our time at light speed. The mathematical model of viewing the universe 300.000 as slow in km is a tricky miss lead.

If anybody is curious enough will ask if light travels a distance of 300,000km in a second how much time does it travel a meter?. Going to the trouble to do the arithmetic pans out to 300 millionth of a second. It is only a matter of comparing the number of meters in 300,000km .

The standard metric system tells us there is a thousand meters in a kilometer that tallies up to a thousand thousand meters where 300,000km equals to a distance of 300 million meters. Math's tells us the reciprocal of 300 million is 300 millionth witch is always one divide a million respectively.  Thus a mathematical formulae tells us we walk a meter light speed travels equals one over, 300,000km times a 1,000.

Thus light travels a meter 300,000,000th of a second. If we use the standard metric  system prefix micro for a millionth, 300 microseconds equals a fraction over quarter millisecond. ( milli- for a thousandth ).

From our point of view it is all relative by the time we walk a meter light had travel 300 million meters. Our mathematical instinct agrees if we do some number crunching tells us since light travels 7  times round the earth equals the circumference 7 times in a second. In other words the math's tell us when we walk a meter in a second  is equal to 7 times round the earth ratio in the same amount of time equal to the circumference of the earth opened out to a 300,000km straight line.

Our mathematical instinct agrees it is only a matter of comparing 7 with 300,000 asking ourselves how many 7's go into 300,000 giving us the circumference of the earth. Our instinct with numbers agrees whole heartily the circumference of earth multiplied by 7 equals to the speed of light that travels in a straight line. Of course the numbers will be different worked out in km or miles.

The reciprocal tells us from light speeds point of view we walk a meter 300 million seconds. Anybody curious enough will be able to pull their mathematical peraleis to calculate how long that is equivalent time in years. From our point of view light is 300 million times as fast we can walk a meter but from light speeds point of view in the fleeting visit to earth time would be equivalent to 300 million times as slow.

By the time light was 300,000km away from earth a person would have walked a whole meter. In other words it pans pout by the time we walk a meter light is a light second away from earth adding a light second every second.

The math's shows time at light speed doesn't stop because time cannot be any slower from light speed's point of view any more than from our point of view light speed isn't any faster than we we observe it. You do the math's.

Some of us actually believe it is not necessarily true we cannot travel faster then light. If this is true our mathematical instinct agrees we can see the implications traveling round the circumference of  earth more than 7 times in a second. There is no reason why not our arithmetic can calculate the velocity 8,  9, 10 or a 100, even a 1,000  a million, a billion, or a trillion times or more round the earth in a second. 

When we accelerate to a velocity the mathematics tells us constant velocity doesn't exist during the acceleration. When we start of stationary reach a constant velocity and to return to stationery we slow down to stop. Einstein's special theory says in acceleration the faster we go the slower time show to stop the opposite should be true, the slower we go the faster time goes.

Einstein's special theory projects time would be observed speeding back up if we slow down from a velocity. Think distance of a distance of a 160km ( 100 miles if you like ) to a stop in a second. Going by the numbers tells us this is not a constant velocity because it is only the time it takes to accelerate and stop in a 160km in a second. You try to calculate the acceleration and deceleration in a kmph equivalent.

The numbers  tells as us take off is 0km to a distance of 80km in 1/2 second then to a stop we decelerate another 80km in another 1/2 second. The math's tells there is no kmph. Einstein's has somthing to say about that about that observing the environment's time. Think of the Marvel comic book hero the flash dashing a 160km to a stop in a second. From an observers point of view would either see him disappear and reappear a 160km away in a second or witness stretch like a rubber band a 160km snapping back to normal a 160km away in the same second.

Einstein's special theory tells us as he takes off he would observe his world slow down, because his acceleration constantly changes faster and faster. The environment's second gets slower and slower, slowly at first slowing down faster and faster as he gets faster and faster. There is a point when the environment's time will seem to stop. It is a illusion because it is only to slow to observe moving.

As he brakes the environment's time should start to speed up again, slowly at first getting faster and faster as he gets slower and slower till finally he finds himself a second into the future when he was a 160km away. Imagine this on a light speed scale. According to Einstein's special theory  projects  the environment's point of view of the flash and from his point of view of the environment round him racing round the circumference of earth the 7 times to a stop in a second.

As he accelerated from his point of view every environment second would get longer and longer. He would view a person walking a meter take longer and longer until the person seems so slow they seem frozen in time. Then as he brakes to come to a stop the person would start to move again getting faster and faster to walk a meter because the second is getting shorter and shorter until the person had walked the entire meter in a second into the future compared to when  he took off. 

The special theory also tells us we cannot travel at light speed because our mass becomes far to heavy on a light speed scale. The next time you are at a supermarket weigh somthing a 1kg ( butter, cheese bag of sugar ect ) in your hand. You will be feeling the force of the earth's mass pulling it to the floor expressed in Newton's, -9,8  to be exact. It is the numerical unit of the earth's gravity. The earth's mass pulls on the 1kg mass equally 9,8N as the mass of your body. When you weigh yourself the scale testifies to this,

Isaac Newtown's third law of force and motion says where there is a force there is an equal and opposite force that defines the property of accelerating bodies resisting acceleration called inertia. Einstein's special theory tells us is relative to gravity expressed as a gravitational equivalence. We feel it in accelerating Rolla Coaster trucks pulling us back into our seats we expresses as G's.

It is a acceleration force of the tucks that terminates the acceleration to a constant velocity where it can't  go any faster called terminal velocity. We only feel the inertia of the tucks during their acceleration. Once  terminated to a constant velocity we don't feel it any more. In truth everything at terminal velocity is than when stationary.

If we let rip a kg mass from the top floor of a tall sky scrapper the earth's mass snatches it instantly accelerating it despite the air resistance where the resisting mass causes the earth's mass to no longer be able to accelerate it any faster has reached terminal velocity. It will tumble all the way down the side of the building until impact with the immovable mass of the street bellow.

All that energy transferred though the kg mass and street in a sudden stop at terminal velocity is testimony of terminal velocity impacts bodies have are much heavier during constant velocity than at rest. If we do the math's on this the impact force at terminal velocity of our 1kg mass is equal to a 1kg, 3.6kmph impact

Einstein's special theory tells us the inertia stored in the free fall terminal velocity of our object at impact has all the hall marks of the equivalent of being in a heavier gravitational field then earth in the sudden stop for second. Density resists bouncing. A basket ball full of air will bounce high in the air. Filled with solid material the force will damage thought the pathement of the street.

We all use the term G's to represent the pull we feel in any acceleration. One G is equal to 9.8N equal to a kilogram per centimeter of the earth's pull or our body mass weighs. The instant a body falls from the top floor of building is a 0 to a sudden acceleration expressed as torque. Two G's of torque is the equivalent of feeling twice our weight in time. Three G's, three times and so on. The maximum we can barely  tolerate is a pull of a 4G's in a second Rolla Coaster take off. Any more is potentially fatal black outs and stopping hearts.

Isaac Newtown's second law says bodies only travel in straight lines. They only change is directed by a force changing the momentum into another straight line direction. We feel the change of direction in Rolla coasters when they hit those tight twist and bends without slowing down at maximum G. For a split second we feel  as if we are going to shoot off the rails straight ahead sensation just before the turn. It is the inertia of the trucks obeying Newton's laws of motion.

When Einstein's wrote the special theory had predicted what NASA has been using for the past sixty years training austronuaghts in weightlessness. We know  when a plane nose dives fast enough austronuaghts lift of the fuselage floor frolicking about in weightless fun. The effect of the dropping motion effectively cancels the earth gravity in the fuselage. In effect the plane has become an antigravity device.

If a plane climbs fast enough austronuaghts can walk upside down on the roof as normal in the earth's gravity. The special theory expresses this a gravitational equivalence. Once Roller coasters are at their maximum speed limits the tucks are at their maximum G. The mere fact we don't feel it at the trucks terminal velocity in straight line straight always is testimony we don't feel any G's at any constant velocity. 

When the trucks slow down we feel the G's pulling us forward resisting slowing down getting weaker and weaker till it comes to a stop. Imagine the G's the flash dashing a 160km to a stop in a second. if you think that's incredible, think of accelerating to a stop in a distance of 300,000km in a second of 7 times round the circumference of the earth. The numbers tells us equal to  0 to a 150,000km in 1/2 second and deescalating another 150,000k in another 1/2 second.

It is relatively arbitrary on the the earth's surface because of the air friction less than a second at take off. Light will do the same even in a vacuum like out of space. The reason-, bicycle pumps getting hot when we pump air into a tire is not from friction you know. It is from compression. In other words compression heats. The G's of light speed in out of space not only crushes a body inward in all  directions reviling black holes but heats it incinerates it. 

Even a tiny amount of matter like a microgram ( millions of times lighter than a kg ) of mass accelerated to light speed is accelerated to a speed only light can travel.

Even if possible less than a second the G's at take off would be so powerful  the molecule of the body would weigh as much as a super tanker and millions of degrees hot. The body would disappear into pure heat called plasma generating light particles called photons. In other words at light speed pressures matter at light speed disappears energy in the form of heat in  line with Einstein's famous e equals m c squared formula.

If we muiltiply the speed of light by itself ( squared, in this case in km, 300,000km/s times 300,000 ) multiplied by a milligram of matter ( commonly expressed as 0.001kg ) equal to a temperature of millions of degrees. Matter is converted to energy. This is what happens when a milligram of properly processed uranium bombed at close to the speed of light by particles splitting the atoms releasing all the powerful heat and energy of a nuclear blast.
