Time is a funny old thing , it's been around for years. In fact it might be the oldest thing in the whole universe and it's still getting older and dragging us along. Time is a pure wonderful thing that zooms through eternity as an arrow of time. While our version of time is a thing called aging!....Time and space are fantastical effects in the physics of the universe ,whereas ,for us it's not the physics ,but the physical....Or the decay and decline of our physical being due to a nice little thing called the LAW OF ENTROPY!....This is quite simply the 'Falling apart of everything over time. Listen to the cracking and clicking of your bones and feel your aches and pains as you get up in the morning, You thought that was old age ,which it is ,but it is much more it is one of the basic laws of physics one of a couple of laws of thermodynamics!....There ,y'go, sounds a little better than arthritus or lumbago!
We think of time as that pain in the arse thing that causes the alarm clock to ring in the morning and makes us rush as we are late for work ,etc and is the reason for rushing and cramming onto busse,trains, the tube and the gridlocked motorway system as we all rush to get to wherever 'ON TIME!'....Times physical form seems to be traditionally bells, from the start of the day with the alarm clock to the vastly more dreaded bell that signifies "LAST ORDERS!" in the local boozer.
What is TIME?....How long does it last?...Is it a second, an hour, a day, a week , a year?????....We have atomic clocks that measure billionths of a second, However we can measure it in either direction ,the small or the large time fills that measurement. We have watches to measure seconds hours ,days and months; We have diaries covering days to years; Doctor Who has his 500-year diary!
A lot happens over time ,we are used to stuff happening instantly ,with computers and the rush of day to day life and living, but major 'stuff' is going on a lot slower and mainly unoticed. Through time the universe was formed ,the Earth was formed; Life formed and slimey stuff climbed out of strange oceanic soups and crawled over that dry stuff which in later years we called 'The Land'. These little 'yukky' thingies eventually developed, or evolved in a thing called EVOLUTION ,ask a certain MR DARWIN about all that, but something daft happened and tiny crustacheans became 200 foot dinosaurs. Which in millions of years would evolve into a thing called 'SUMMER BLOCKBUSTER MOVIES' for the lazy movie buffs that the dinosaurs ,etc would be replaced by over time.
Nothing stays still as time passes , mountains grew and disappeared ,oceans came and went; continents ground against each other and formed new mountain ranges ;continents split and stuff like a lump of rock which would evolve into America over the other side of the developing planet....There may've been volcanoes and eartquakes destroying and shaping the planet, but at least America is 'over the 'pond' which was also formed.
A lot has happened the planet was shaped by comets destroying the dinosaurs , Man evolved ,invented fire n' wheels n' soap operas and even there was a time England won the world cup ,a lot has happened through time.
But things happen over time which may not be epoch lasting ,world-changing, but defy the laws of living and life. When i was a younger lad and we'd go out on 'the razzle' on the weekend, we'd be looking for something to wear to impress 'the chicks' at the Liverpool nightclubs. At the beginning of the week i'd dump my dirty ,highly pungent socks n' 'Bills' ( Bill grundies....Undies!)....Into the laundry basket like workers in radioactive labs carefully inserting the radioactive core rods into the reactor core. At the end of the week you were looking for socks n' 'Bills', but couldn't find any ,so you'd root around in the laundry basket and!......Your SOCKS N' BILLS DIDN'T SMELL...Quite as bad!.....They could be worn, go on , you know what i'm talkin' about!.....This is a real example of Times effect on organic (sort of ) life forms.....As sometimes i was sure the socks n' Bills moved themselves. My socks n' bills evolved over time and cleaned themselves!?
Time does have it's mysteries which will never be solved ,but affect us in our daily lives. Most of us wear a watch and many of those watches have a little square hole with a number signifying the day of the month by the number 3 (quarter past). The date hole is normally quite small so they put a thick block of glass to cover it and magnify the date number. The unbreakable law of physics is that whenever you want to look at the date ,IT IS ALWAYS QUARTER PAST!!!?...So whenever you need the date you cant as the finger of time is pointing to 3 ,covering the date, So you have to hang on for a few minutes into the next day to get todays date.
What is time ? Is it the point when Doctor Who starts on a Saturday night, or the kick off for the football ....( or Rugby!) ?......Or is it old black n' white telly or films, so you know its old , or does time exist in the real world outside of the telly screen? The guy who 'sorted it' was a well known ,now scruffy pipe smoking patent clerk who would one day have possibly the most famous moustaches in history. Yep!..You guessed it ALBERT EINSTEIN.
Einstein must've been a funny bloke as he sat and conducted his 'THOUGHT EXPERIMENTS' imaging why things happened ,like "What would it be like to sit on a beam of light!"....Usual stuff like that. Must've been great fun to go to the boozer with him. He developed to amazing theories that even todays smartarses want to prove wrong can't! He did the SPECIAL(Involving high speed travel) and GENERAL( Gravity n' stuff!) THEORIES OF RELATIVITY. And all together now!!!....E=MC2!!!
It's all clever complicated stuff, but he basically said that SPACE N' TIME are linked into a thing called SPACETIME. Basically there is no time as such ,the forces of energy n' mass distort space and time which is gravity and all the stars and planets spinning through space under the influence of distorted spacetime. And just to make it a bit more interesting if you fly through space at great speeds and distances say from Earth Time is totally shot!....A ship leaving the Earth would seem ok on board, but time would slow for them as it would speed up in relative terms, so on return ,possibly hundreds of years could have passed on the Earth for a few years on a very high speed ship.
An airplane flying overhead exists on a different ,albeit a tiny bit of a different time , they will be aging slower than us on the floor. Your sat navs have to be tuned into the satellites, but allowance has to be made for relative changes in the passage of time to get it to tell ,accuratly where you are.....roughly....That field 5 miles from where you want. But although time is a variable time travel will never happen as the universes speed limit is the speed of light. Light has little ,if any mass ,so you could carry a lot without straining yourself, but as it flashes through space Mass is negligable so it's virtually Energy =C-speed of light 2, so thats a lot of energy ,almost a universe full ,theoretically it could manage 9.999999999999999999999999999999999999% recurring the speed of light! If you could overtake that maybe the universe would seem to go backwards. They theorise Tachyons actually live on the other side of the light limit, so they exist in a backward universe.
So theres no going back to kill your grandad....So you wont exist ,so you can't kill your grandad, so you can exist and go back to kill your grandad ,so you wont exist, etc, etc ,as the 'good Doctor would say you 've created a 'time loop'. What would happen if you went back , met your grandparents to be and fell in love with your grandmother ,to be and 'you got together!'......So your seed was planted back 'in the day!'....What kind of time loop would that form?.....Maybe a time coil would've been better!
