  1. I accept that timedilation happened in a field of gravity. But to a conscious astronaut, he/she will experience his clock ticking at a normal rate. There will be no difference in time perception for him. Take the following thought experiment from special relativity: on a ship travelling near the speed of light relative to Earth, the observers on that ship don't experience a dilation of time, nor a shrink of their ship. To them, everything on the ship is perceived 'normal'. To them: Earth is shrinking in one direction and the clocks on Earth do have strange effects. To the conscious obser
  2. My claim is that conscious observers have their own particular clock and their own particular ruler. A reference for time and a reference for a straight uncurved, unstretched ruler. Wherever we are, as conscious observers, we experience the same time rate passage. And we have our local idea of what's an uncurved and straight ruler. Time So, far above the Earth, scientists say: the time rate passage goes faster, due to gravitational timedilation here on Earth. Gravity slows down time. But what's actually happening is: relative to an observer high above th
  3. What's wrong with the following reasoning? - The past is gone (doesn't exist (anymore)) - The future isn't there yet (doesn't exist) - The actual moment is all there is. - The actual moment can't have a duration, because in that case it could be divided into a past, present and a future. So, the duration of the actual moment must be 0 sec. Conclusion: time is an illusion.
  4. But, the past is gone and the future isn't there yet, in our experience. Only the actual moment exists and is real. We observe the past, but we are in the present moment, and that's all there is to our conscious experience. Even when you remember something from the past, it pops up in the present. Because the present is all there is (to minds).
  5. In philosophy of time, you have eternalism and presentism. Eternalism says: there is the block universe where past, present and future co-exist as one block universe. Presentism says: there is only the present moment. My idea is: to a conscious mind, there is only the present (presentism), but a universe without minds is a block universe (eternalism). So presentism and eternalism are both true, depending on the perspective you are using. The perspective of a mind/observer = presentism. The perspective of a universe without minds (even animals, although they could experience time diff
  6. We only experience a 3D-universe, in the actual moment. We only experience the present. (philosophical presentism) (we observe the past, but we observe it in our present moment). The present moment is all there exist for an observer. But without observers, the universe in itself, is eternalism. The block universe where past, present and maybe future co-exist. This video explains the difference between our human experience and spacetime very well: The philosophical aspect would be 'consciousness' or 'mind' that's added to physics. Our experience of a 3D spa
  7. Why do we only experience a 3D-world, while it's actually a 4D spacetime universe (Einstein) where past, present and maybe future co-exist simultaniously as some block universe? Due to the interaction of consciousness with this 4D-spacetime- block universe, we only experience a 3D world.
  8. Ask yourself these questions: What is a straight line for observers in different, curved spacetime environements? Is it the same straight line for all observers? Or do we disagree about our ruler? For every observer, his particular idea of straight uncurved ruler (a straight line) is an individual idea of space, like he has an individual clock (time rate passage). Whatever an observer will see as a straight line, in his own referenceframe, will be curved somewhere else by heavier masses. Whatever an observer will see as a straight line in his own reference frame, will be
  9. So, you see the universe through the lens of your clock. An observer near a black hole, who will think that time on Earth is stretched (according to his idea of time), will observe Earth differently then we (here on Earth) do. We have the same clock then Earth has. (same time rate passage, same timeflow). So Earth stands still, relative to us here on Earth. Because we have the same clocks and rulers. (please reply with the analogy of observers and their clocks and rulers)
  10. Please, explain this in terms of observers and their clocks and rulers. An observer near a black hole will have a different idea of 'the stretch of time' here on Earth. To the observer near the black hole, time is not curved here on Earth, but stretched. (according to his idea of time near that black hole). To the observer here above Earth, time is contracted on Earth. (very small, but contracted). Both observers (near the black hole and an observer above Earth) have their own clock and their own ruler to determine the 'curvature of spacetime' on Earth. They have their own idea of st
  11. I should say that the influence of curvature by masses on a clock is not knowable. Because there is no zeropoint to compare too. I mean, there is no zero gravity environment where we can put a clock or a ruler and compare it with our clock and ruler in our gravitational field. There is no objective standard for time and space. We can only compare the influence of Earth's gravity on our clock with another clock in another gravitational field. Small is therefore relative. Depending on with wich clock you compare it too. All the environements are curved somehow. So, to us, obser
  12. But small is relative, isn't it? The influence of the black hole in the centre of our galaxy and the whole system we are part of (the galaxy) and the cluster of galaxies on our clock and ruler is very big, isn't it? The influence of a system of clusters of galaxies on our clock and ruler is big, isn't it? But to us, our clock ticks 'normal'. We use our clock and ruler as a standard, to state: that galaxy we observe over there has this space-timeproperties. It totally depends on our ruler and our clock. On our telescope in our field. In my theory there is no zero gravity condit
