13 FACTS ABOUT TIME THAT WILL HURT YOUR BRAIN


Passage of time is quicker for your face than for your feet (supposing you’re status up). Einstein’s theory of relativity states that the earlier you are to the center of the Earth, the slower time passes – and this has been previously measured. For an example, at the top of Mount Everest, a year would be about 15 microseconds shorter than at sea height.   
A second isn’t what presently you consider it is. Technically, it’s not distinct as 1/60th of a minute, but as “the period of 9,192,631,770 periods of the radiation reliable to the transition between the two hyperfine levels of the earth state of the caesium 133 atom”.


When the dinosaur ruled the Earth, there were nearly 370 days in a year. The Earth’s turning round is getting slower because the moon’s seriousness is acting as a drag, so days are receiving lengthier, by about 1.7 milliseconds per century.                                                                                                                      


This one is good quality. On Mercury, a day is two years long.                                            
The least normal scientific amount of time is the “Planck time”. It only take you about five hundred and fifty thousand trillion trillion trillion Planck times to blink one time, fast.                                                                     
There’s not anything as “now” according to physics. Space and time are like fluid, exaggerated by gravity and still your speed. Albert Einstein put it like this: “For us physicists, the difference between past, present and future is only an illusion, though persistent.”                                                                           

Since light take time to arrive at us, whatever we see is in the past. The sun you can see in the sky is 8 minutes and 20 seconds old. The glow from our nearby star, Proxima Centauri, is about 4 years old.                                                     
New experiences certainly do come into view to be longer in the memory than recognizable ones. It’s known as the “oddball effect”, and it appear to be why time feels like it’s going quicker as you get older – since more stuff is familiar to you.   The majority precise clock ever construct is the strontium clock, which is precise to within a second over 15 billion years.                                                     
The oldest acknowledged thing in the space is a galaxy called z8_GND_5296. It’s 13.1 billion years old – only 700 million years younger than the cosmos itself.                                                                                                

The cause at the back why clocks show the same time crossways entire countries is that it make train timetables easier to run. Till the 19th century, towns set their clocks by the local time or noon, so clocks in Bristol would be 11 minutes behind London. That destined people kept absent their trains, so railway firms begin using standard, London-based UK time, initiating with the Great Western Railway in 1840. 
                                                                
Time might be crunch to a pause. Distant galaxies seem to be moving earlier than close ones, signifying that the cosmos is accelerate as it expands. The normal theory to elucidate that is a mysterious force in the cosmos known as “dark power”.


But a Spanish physicist has suggested an option prospect that the further-away, older galaxies only come into view to be moving faster since in the past, time was faster. If he’s correct, in a few billion years, “all will be frozen, like a photo of one instant, endlessly”.         

                                                       Next week, your watch will be one second behind. The detail that the Earth’s spin is decelerating, and consequently the days are receiving longer, means that our 24-hour day is very to some extent off. Every so frequently, the global Earth Rotation Service, the bodywhich standardizes astronomical time, has to add a second – called a “leap second” – to the clock to retain things steady. The recent leap second was on June 30, 2015.

  2. Could the writer of this article please learn English? Terribly difficult to follow the multiple syntax and grammar errors.

  3. Glad it's not just me. The concepts are not what gave me a headache.
