Time is Relative

 Is time moving faster we've all heard the cliche phrase but according to physics time is actually moving slower 100 years ago we believed that time was the same for everyone and everything we were all participating in the same ticks of the clock every interval of time was the same as the one before and it moved forward in a linear uniform progression however in 1919 Albert Einstein demonstrated that time is relative with a theory of special relativity he discovered that time slows down or speeds up depending on how fast you move relative to something else we know that when you travel faster for instance time moves slower this is something NASA has had to account for in their satellites which move around the Earth at 29,000 km/h the clocks onboard each satellite ticked slower than identical clocks o  the ground by about 38 microseconds per day each microsecond is one-millionth of a second this sounds small but the high the precision of the GPS system requires nanosecond accuracy and 38 microseconds is 38,000 nanoseconds if these effects were not properly taken into account a navigational fix based on the GPS constellation would be false after only two minutes and errors in global positions would continue to  accumulate at a rate of about 10 kilometers per day the whole system would be utterly worthless for navigation if we were not able to adjust to relativity the closer you travel to the speed of light the slower time travels according to the theory of relativity if two identical twin babies were part of an experiment where one baby goes into a spaceship that blasts off at 99.99999% speed of light and the other baby stays on earth the babies would experience time in very different ways 80 years later the baby on earth would be an old man and the baby in the spaceship would have only aged one day as it turns out we are moving faster the universe is expanding and this expansion is happening at an accelerated rate the farther something is from our galaxy the faster it is accelerating away from eventually, these distant objects move so far away that they fall off the visual cliff and are no longer part of the observable universe at least from our perspective the light from the galaxies beyond the visual edge will never reach our telescopes here on earth so you might be wondering if our galaxy reaches the speed of light could time freeze perhaps this is why time feelslike it's accelerating if time were slowing down more events could happen in shorter intervals of time and we are witnessing a rapid rise in technology knowledge understanding evolution and extinction which is all accumulating at an exponential rate could this acceleration of events be evidence that time is actually slowing down if so then what is this acceleration leading to now this is a complicated idea for another  Article.

Do you really understand Einstein’s theory of relativity?

  Albert Einstein's theory of general relativity completely changed the notion of the Universe.  It shed light on the birth of the universe, planetary orbits, and black holes.  It also has very practical uses, like GPS navigation.  But what exactly is this theory and why was it so revolutionary?  Until the early 20th Century, physics was mostly explained in terms of Isaac Newton's  laws. For Newton, gravity was a force generated  by the mass of an object causing them to attract each other,  heavier objects pulling others more intensely. This is why we stand on the ground on Earth,  said Newton… it attracts us to its center.  And it’s why planets move around the Sun. But imagine if the Sun disappeared completely.  According to Newton's theory, the planets of the Solar System would instantly  abandon their orbits, as there would be no gravity attracting them to the Sun.  For Newton, gravity is a force with immediate action ...

Black Holes Explained – From Birth to Death.

 Black holes are one of the strangest things in existence.  They don't seem to make any sense at all.  Where do they come from...  ...and what happens if you fall into one?  Stars are incredibly massive collections of mostly hydrogen atoms  that collapsed from enormous gas clouds under their own gravity.  In their core, nuclear fusion crushes hydrogen atoms into helium  releasing a tremendous amount of energy  This energy, in the form of radiation,  pushes against gravity,  maintaining a delicate balance between the two forces.  As long as there is fusion in the core,  a star remains stable enough.  But for stars with way more mass than our own sun,  the heat and pressure at the core allow them to fuse heavier elements  until they reach iron.  Unlike all the elements that went before,  the fusion process that creates iron  doesn't generate any energy.  Iron builds up at the center of the ...
