Everything keeps changing whether it’s the smallest thing or the largest thing you can ever imagine.
A 6 year old asking me a question “What is time?” I didn’t understand his actual question and answered its 5.30pm but then I paid attention and realized his question isn’t as easy as it may appear.
Give it a try….
How will you define TIME?
If you ask me my answer would be something like this……
Time is what keeps everything from happening all at once, and so time is that part of the world that orders events in a certain way so they happen sequentially, from beginning to end.
It’s one of the most challenging topics in science, questioning our most basic assumptions about reality.
Is time a fundamental part of the Universe, or could it be that time doesn’t really exist?
It’s an interesting dimension (by far the most intriguing dimension I’ve ever encountered) to consider and the ways of interpreting time lead to enormous implications. Einstein was the first to state time as a dimension and it made a whole lot of sense and in came the time-space saga. The best part of adding time as a dimension was that it made life easier for human beings to understand what’s going on in the universe. But there is a twist to this….
Sometimes it is worth a thought that “Did we create time?” Well, there are people on either side when it comes to this question and both of them are right logically and sensibly in their own way but ultimately there is just one answer.
How did time come into existence??
Well according to Newton ‘God’ kick started time which we call Absolute Time and Einstein thought it was relative ergo Relative Time. Of course now we all that Newton was wrong and time is relative. Or is it?? If you ask me, the simplest example I can give you with respect to relative time is a stopwatch. The moment you start it’s the beginning of that time and when you stop it’s the end of that time. It’s all just stopwatches some run for a couple of seconds and some run for billions of years. The stopwatch in which we live was started 13.7 billion years ago. Don’t ask me who started it. The relativity of time causes a lot of strange effects, such as time running faster for astronauts than people on Earth. But Einstein’s solution to the mystery of time opens up an even more challenging notion. If we look around, we see that all of space exists right here, right now. So, doesn’t it follow that all of time — past, present, and future — already exists, as well? Could it be that the future is already here?
Is time an ILLUSION or a REALITY????
Physicists who deal with mathematics and numbers all their life trying to find a perfect synchronization between mathematical equations and existing reality. These are the group of people who think time is indeed an illusion. In their defense we should consider that the numbers they deal with, the parameters, the equations are static in nature they don’t change. Whereas Time is the most dynamic thing we know. The value of π in the morning is same that in the evening. Some Physicists can convincingly prove us that they can remove time out of all the mathematical equations and still justify everything right from the Big Bang. They are neither wrong nor they looking it the wrong way, it is a dimension which is worth considering this.
This was the illusion side of time but there many infact most of the people think time is real and it is very much a part of human life. Physics says that all the moments of time are equally real, and that tempts us into saying that they all exist simultaneously, they all exist now, but that’s not what it’s like. Different moments of time are really like different places in space. They’re not here. They exist, but they’re somewhere else. The difference is that, unlike space, we can’t help but experience time one moment after the other. We can’t go back to moments in the past, and we can’t, right now, talk to moments in the future.
This sort of temporal dislocation seems to contradict the laws of physics and human experience. Or does it? Maybe not.
Eventually time may just be in our heads. That’s a bold statement to make but the relationship we humans share with time changes with time. Eh?
Let me try again….
The older we get, the faster the currents of time seem to carry us along. Our relationship to time changes as we age. Studies show that the passage of time seems to increase by the square root of your age. So, if at 10 years old, it’s 1:1, when you’re 20, its 1:1.4. And by the time you’re 60, its 1:2.44, about 2½ times faster. We all experience time at one second per second, but it doesn’t feel that way.
Our brain can also lead us to see time differently…
It takes a few millionths of a second for our brain to put together information and serve it up to your consciousness, which means that we’re all living a tiny bit in the past. This time delay is the tradeoff our brains make to give us the best story of what happened. But when the brain doesn’t get the story right, it can change your relationship with time.
I think that time might be the most stubborn psychological filter that we have, and that when we start really reaching down below that, when we start really figuring out how time is constructed by the brain, we’re going to have to go back to physics and rejig all of the equations there. As I said before there are scientists who have realized all the Einstein’s equations without time in blunt terms eliminated time from the physical description of our universe.
It’s always a great sight to see some of the top scientists and theoretical physicists having a go with so diverse ideas and following their own quest in an absolutely different way to find an answer for the same question for the sake of mankind.
What matters is how objects relate to each other in freeze frames of space. My view of the Universe — it’s just like a huge collection of snapshots which are immensely, richly structured. They’re not in any communication with each other. They’re worlds unto themselves. But each world is so rich that it’s, so to speak, part of this world. It’s snapshots within snapshots. This is really what our life is about. Our brains assemble these frozen moments and play them in our minds the same way that still photographs played at 24 frames per second make the images you’re watching now seem to move. But nothing is moving. What we call “time” is an illusion. In some very deep sense, the Universe, the quantum universe, is just static. Nothing changes. All of these snapshots of the Universe exist simultaneously. If I were to say that my yesterday no longer exists, it would be like the number 13 saying that 11 has died. Mathematicians would regard that as ridiculous. This instant is so vital and so alive, but in a way, it’s eternal. This when you translate that into mathematics, it’s eternal.

We can make space not fundamental, but time remains fundamental. There doesn’t have to be anything more than time, and you can’t do it the other way around. You have to start with space and then get time. So, time is at the very bottom level. I think even this is what the physics is telling us, although we haven’t been paying enough attention to it.
– Tim Maudlin
There are a lot of people in physics and philosophies who think that time is an illusion, that what’s really true at the deepest, deepest level is timeless, is outside of time. And I don’t believe that. I used to believe that, but I’ve come to believe that time is really, really real.
– Lee Smolin
Time may be real or it may be an illusion. But from our perspective, the past is gone forever, and the future is yet to be written. Whether or not we discover there are physical aspects of time we can’t perceive, our human experience of the endless cycle of life and death won’t change.
The instant is not in time. Time is in the instant.
