  1. Thanks. I am trying to wrap by brain around this in practical terms, from the point of view of two separate observers. So let's say this thing we call 'TIME' only comes into existence at the point of creation. We both agree that we are viewing the same event. You say that thing we call TIME, that only came into existence at the Big Bang, can be different for the two of us - RELATIVE TO US. For me the event could have happened 15 billion years ago and for you only 13.75 billion years ago. I'm using smaller differences based on replies. But assume any difference, even slight. If we are on different galaxies, let's say you are on earth, I'm in a different galaxy on a different planet. What does 13.75 billion years even mean to me? I would have my own units of time based on my planets rotation, etc……If I never knew about earth I would have no idea of your concept of TIME. I can only compare TIME relative to you based on your measurement of time. Right? Maybe what I call 15 billion years on my planet could be exactly 13.75 years on your planet. Or maybe what I call 1 billion years is only a million years to you. I can only compare TIME relative to someone else. So now the concept of 'TIME' becomes something based on you. Time is not 'external'. Time is what you experience and can only be different when compared to someone else. That's logical right? Let me give you a better example. Say I build a time machine and I travel forward in time by a 100 years, but during the trip I lose my memory. How will I know that I have traveled forward in time? I won't know it unless I have some point to compare it to. I will simply be in the present, not in the future. Now let's go back to the Big bang. We are on different planets. We both observe the same event - The Big Bang. If we never ever meet each other to compare experiences. Time for each of us will be whatever we say it is. I can say the universe is 15 billion years old based on what I call a year. And you on earth can say the universe is 13.75 billion earth years old based on earth time. If we do meet, or contact each other somehow, and want to compare our notes on the age of the universe. One of us will have to convert their units of TIME to achieve anything. If we do this. I can only conclude that my 15 billion years is exactly equal to your 13.75 billion years. Because TIME is only what each one of us says it is. You could of course use my measurements and agree that the universe is in fact 15 billion Spagoolars old (that’s what we call a year on my planet). In either case we are using the same measure of TIME. A UNIVERSAL notion of time. If TIME indeed has a creation point at the moment of the Big Bang. Lol. I am getting lost in all of this. But thanks for taking the time to engage. I love this topic. I can't help but feel there is something very important here. If you get into a spaceship and travel at twice the speed of time. Or close to a black hole as per your example. How will you know that you are experiencing TIME different to me? You can only know if you compare it to me and convert your units of time to mine. If you come back to earth from your trip to the event horizon and find that I have aged 60 years and you have only aged by 6 years. Then your 60 years must be equal to my 6 years. Right? If its equal it must be the same. Right? This only matters if we have a "start point" or "big bang", lets say you left for the event horizon when we were both 20 years old. That's our reference point. If you have no reference point, you could go to the edge of a black hole and come back and never know that you traveled faster or slower because you have nothing to compare it to.
  2. "It is the same event, but different amounts of time have elapsed since then as measured by different observers. " Hhhhmm. This is what I wanted to hear. So you saying that the universe could be, say 30 billion years old, for some observers? So the age of the universe is only relative to us then? P.S. I am not really claiming that there is a "UNIVERSAL TIME" or 'ABSOLUTE TIME', I think there is in fact no absolute time and the universe could be eternal, but only 13.75 billion years old relative to us.
  3. But do you agree that if TIME itself only came into existence at the moment of the Big Bang, that time must be the same for everyone inside the universe? You can call that 'TIME' whatever you like. It must be universal. The universe cannot come into existence relative to us (at different points in TIME), if we are in different galaxies for example, because TIME itself never existed before the Big Bang. So before this we had no different points in TIME. Time did not exist (according to Big Bang). So if TIME only came into existence at the point of the Big Bang, that TIME must be 'THE SAME' to everyone inside the universe. It must be UNIVERSAL and not relative. You say "NO", please elaborate. Explain how that TIME can be different for beings living in two separate galaxies for example. How can the universe come into existence at two different points in TIME, if TIME itself never existed before the Big Bang? How can that 'TIME' be relative. It must be universal. Or the Big Bang must be wrong. Thanks for taking the time to ponder this.
  4. If the Universe started approximately 13.75 billion years ago as theorized by the 'Big Bang' and TIME itself only came into existence at the moment of the Big Bang, then surely this must be 'Universal Time'. Yet Einstein and special relativity shows us that TIME is relative. There is no such thing as universal TIME. This has been experimentally proven. So then how could TIME only have come into existence with the Big Bang, as accepted by many supporters of the Big Bang. If TIME only came into existence with the Big Bang then that time would be universal. The universe would be 13.75 billion years old for us. And if there are aliens living in another galaxy the universe would have to be 13.75 billion years old for them as well. That Time would not be relative to either of us because the universe would have come into existence at the same moment for everyone in the universe. We would now have an entity that has been missing from physics - Universal Time. A concept of TIME that is not relative and cannot be relative because the same universe could not come into existence at different points in TIME for beings living in separate galaxies, if TIME itself only came into existence with the Big Bang. If that is the case then the universe is only 13.75 billion years old, relative to us here on earth but could be any age. Thoughts?
