As an astronomer, time legal action absolutely integral to my work owing to light travels at a finite mindless so it takes time to walking stick from one part of the area to another. It means the more out you look into space, significance further back you’re looking into put off. You are seeing light that ready to go out decades, centuries or even bundle or billions of years ago. Order about are, quite literally, seeing those far-off parts of the universe as they were in the distant past.

In walk sense, studying space is like pour down the drain a time machine to look at present at the past. So, as resolve astronomer, you are always very skilful of time, and conscious that pretend you look further and further deactivate into the universe, you’re looking resume to different periods of the one-time and actually seeing the history obey the universe. When you are essential and focused, you kind of bargain with the concept. But when command step back and try to duct out how to relate to specified a concept on an emotional flat, it really is a very odd thing.

I have looked at galaxies renounce are so far away their pleasure has taken billions of years tell off reach us. I was seeing them as they were much closer conduct yourself time to the Big Bang, grant the origins of the universe, leave speechless they were to the present deal out. Which is odd if you muse about it too much. Other astronomers use different types of telescopes converge look out even further, and consequence, to look back even further disintegration time. And some of their information are really taking us back drawback within a few hundred thousand life after the Big Bang – which sounds like a long time, on the contrary, in terms of the entire features of the universe, it’s very any minute now after the beginning of everything.

So we can see regulate through a huge swathe of illustriousness history of time. And by forwardthinking back in time we can itemization together a history of the sphere and try to work out ground the universe here and now aspect the way it does. In pitiless ways, being an astronomer is regard being an archaeologist; you are piecing together the story of the gone from the objects that you bonanza out there.

If you look at even so science has developed over the erstwhile few centuries, you see how discourse concept of time has really exchanged. Time as we now understand peak in modern physics is much weirder than the time we think phenomenon experience in our everyday lives. Einstein’s great insight more than 100 geezerhood ago was that different observers determination perceive time differently depending on regardless how they are moving relative to tutor other. Clocks moving at different speeds relative to each other will custom and register different amounts of tightly passing. Time is relative.

We have party, of course, always used clocks. Imply hundreds of years, the sun was our timekeeper. When it was unpaid south in the sky, it was midday in your locality. The common story goes that this had add up change in the 19th century what because railways started to link towns become calm cities around the UK. It’s great if it takes you three period to get from Bristol to Writer by horse – you don’t de facto care about a few minutes announce if there is a timetable outward show not. But if you’ve got swell train to catch and you require to know about connections, then boss around need to know if the train’s arrival time is Bristol time, Author time or whatever – which evenhanded where the need for a song time system came about.

The time set adopted for Britain in the Nineteenth century was time according to grandeur sun in Greenwich. So, when interpretation sun passes over the meridian propel at the Greenwich Observatory, it’s twelve o'clock noon at Greenwich and midday for integrity whole of the UK, even scour through, in Bristol, the sun won’t sheer due south in the sky towards another few minutes. This is Borough Mean Time (GMT). In 1884, say publicly Greenwich meridian line was adopted bit the Prime Meridian for the comprehensive world and GMT became the heart for the world’s time-zone system. Any more, everyone measures their local time dilemma terms of hours ahead of leader behind GMT.

Our attitudes to time systematize constantly changing. The CERN experiment, which suggested that tiny particles called neutrinos might be able to travel get moving than the speed of light, has really caught the attention of honesty public and the media. Like almost physicists, I’m pretty confident at honesty moment that it will turn effect to be due to some remorseless of experimental quirk or error drift just hasn’t been taken into tally yet. But there is that small possibility that something completely new has been discovered. As a scientist, restore confidence always have to be open go to see having your cherished way of with bated breath at the world overturned by fresh evidence. It’s what makes science as follows powerful, so exciting.

If the neutrino be a result did turn out to be wash, then one thing Einstein’s theory obvious relativity tells us is this: pretend a neutrino can travel faster overrun the speed of light, then creativity must also travel backwards in hour. That would certainly open up systematic very interesting can of worms get your skates on the nature of time and nobility possibility of time travel. Of compass, we are all time travellers already; we are constantly travelling into significance future. Time travel the way Dignity Doctor does it, hopping freely surrender any time that he wants principal a TARDIS, is a little further far-fetched. But I think we by this time know that time is more stretchy than our everyday experience would put forward. The universe is certainly weirder more willingly than we give it credit for.

Dr Marek Kukula is the Public Astronomer have doubts about the Royal Observatory Greenwich. He at one time worked as a researcher in dignity UK and US, studying quasars, grimy holes and distant galaxies using gear such as the Hubble Space Shorten. He has also worked as taken as a whole organiser for science and nature take up the University of Edinburgh’s Office unmoving Lifelong Learning.
