  1. It doesn't, indeed. It was related to the question of contemplating the present and the individual experience of it. Off topic.
  2. I love both farting unicorns and leprechauns. I was referring to a period of classic physics period where this idea of absolute value concerning time reigned (thus my subtle reference to Renaissance) ..too subtle ?! As I was saying the experience of time at individual level is highly subjective and to a large extent, yes, we are subjects of processes that operate on timescales so short they feel instantaneous. These processes are essential for navigating the world, allowing us to react to immediate dangers, make quick decisions, and process sensory information at speeds that support fluid interaction with our environment. Having that in mind there is a difference between the perception of instantaneity and the actual temporal dynamics involved. From a neuropsychological standpoint, what is perceived as instantaneous is the result of highly efficient, but not temporally zero, processing times. It was clumsy from my side to write that thought without further explanations, as remarked by another participant.
  3. Some of our processes are instantaneous. I am particular thinking at driving experience, for example. And I agree with the idea of building a "virtual present" The experience of time at individual level is highly subjective. Coming back to the question : "Could we observe the present ?". The speculative answer would be yes. if we have a fixed point in the univers, an absolute clock somewhere …(but it sounds so...Renaissance )
  4. Must be some species preservation mechanisms. Joggling between "past" experiences and "predicting on the go" the present?
  5. a bit off topic: at individual level, the way the consciousness is "awake" and building the reality is already altering the process of understanding the present or it has something to do with it. I am referring at "time slices" of consciousness every 400 millisecondes. The present is the prisoner of the law of synchronicity/simultaneity (two events occurring at the same time are perceived differently depending on the observer's frame of reference). To grasp the present, Time would need to be absolute in value.
  6. I apologize. It mainly tries to solve AMPS paradox by EPR approach: 1. Entanglement of "space" in vacuum 2. Entangled Black holes (so it implies "un" entangled black holes) 3. Entanglement as a phenomenon generating/ creating spacetime 4. Entanglement quantum phenomenon bridging GR and QFT I suppose the scientist needs no introduction. He's part of the team working/starting string theory.
  7. This was somewhat expected, an inevitable trajectory for General Relativity (GR) when considering very small scales and gravity. There are no surprises there. From this conversation, I am taking some points: Philosophers must follow compulsory courses in physics, and physicists must follow courses in philosophy! GR is effective on large scales but overlooks the quantum scale, which can lead to a metaphorical 'stiff neck' from trying to reconcile its implications. QFT becomes essential when dealing with massive black holes. At the quantum level, uncertainty reigns supreme, guiding the behavior of nature. Though, in the eyes of a profane, it looks like you can't have a piece of knowledge if you don't trade their piece of knowledge... 'Singularity' might just be a term for our current lack of understanding. No bridge yet (except string theory ? ) between big things and small things. Intuitively, this sheds some light on my initial question: the singularity at r=0 isn't a location; it's a moment in time, or more precisely, many locations along a time-like curve. I'm assuming that space in this scenario could resemble crumpled paper. Yet, I would like to know if this 'crumpled paper' has a breaking point, despite knowing that any analogy is inadequate when facing such counterintuitive levels and forces at play. Thank you all! @Moderators: feel free to close the subject, though unsolved. I have seen my mistakes of conception and methodology.
  8. This was the initial question. And this is the answer I was looking for.
  9. I am indeed a fan of 'Star Trek'! However, I'm not sure I understand; I thought it was generally accepted that nothing escapes from black holes, except for Hawking radiation. How do you relate it to Heisenberg's principle?
  10. I agree and understand. This is a forced, and probably inacceptable “trickery”. My reference to the electron was intended as a measure to conceptualize extreme density, a point-like mass in the Schwarzschild solution, rather than a literal size reference. I see how my initial thought may have strayed from the accurate mathematical framework and approach. I'm interested in whether it's theoretically possible for the geodesic paths around such a dense point (conceptualized as extremely dense but point-like for mathematical purposes) to be altered to an extent where the angular movement approaches a 'zero degree', or close to it. Essentially, could such extreme density lead to a spacetime configuration where the paths taken by objects or light become radically different ? As space and time are connected I am assuming that if one is affected the other one will be as well. (I belive it might be over my head these concepts and scientific work...I am seeing my own "event horizon" )
  11. In considering Quantum Field Theory (QFT) in relation to my ideas, two key aspects come to the forefront. Firstly, there's the matter of scale. QFT deals with the extremely small, like electrons, and it's this microscopic scale that's central to my thoughts. Regarding the nature of time, its treatment in quantum mechanics presents a complex picture. Time in the quantum realm doesn't always conform to our everyday understanding. The role of the observer, a fundamental aspect of quantum theory, adds another layer of complexity to how we perceive time in these scenarios. For the moment, it looks more “manageable” to focus on a basic yet fundamental aspect of time: its unidirectional flow. While the deeper essence of time remains elusive in quantum contexts, acknowledging its consistent forward progression provides me a practical framework for further exploration (l am aware that simplifying it has its own dangers) I have read the post “Does time exist? “ (https://www.scienceforums.net/topic/125382-does-the-time-exist/#comments) and I have to admit it sometimes eludes my understanding and my intellectual tools. But it looks fundamental as, in my perspective, it connects it to the question of “Existence”. Poetically – if it is, it flows! Additionally, the concept of matter decaying over time, a well-established phenomenon, prompts a thought: could this be an example of an interaction between matter and time?
  12. I'm approaching this topic with a sense of curiosity and exploration, fully aware of my non-scientist status and the speculative nature of these concepts. My thoughts are grounded in an opportunistic use of established theories, in ways that deviate from their standard applications. In my hypothesis, I imagine a scenario where an object with a mass 20 times that of the Sun is compressed to the scale of an electron. This extreme condition, I speculate, might lead to a significant alteration in spacetime curvature, potentially reaching what I am thinking of as a 'zero degree' in the geodesic path. At this point, I wonder if spacetime could experience something akin to a rupture. The observer in this scenario is posited within a unique frame of reference, influenced directly by these extreme conditions. This is a departure from the relative frames typically discussed in physics. As such, this observer's experience of time might differ radically from our conventional understanding, potentially displaying properties like bidirectionality. As for the mathematics underpinning these ideas, I'm drawing inspiration from the Schwarzschild and Kerr metrics, which describe the gravitational field around black holes. While my understanding is limited, I'm intrigued by how these metrics might behave under the hypothetical conditions I've described. The negative time dilation values, which emerged from my rudimentary calculations, suggest to me a departure from traditional interpretations, possibly indicating a breakdown or unusual behavior in spacetime. I recognize that my approach is highly theoretical and not based on the rigorous mathematical frameworks that professional physicists would employ. It's more a thought experiment, a way to imagine what might happen under extreme conditions and how that could possibly relate to our understanding of the universe's beginnings. Defining a Unique Frame of Reference: Is it theoretically possible to define a unique frame of reference that is influenced directly by extreme gravitational conditions, such as those created by compressing a massive object to the scale of an electron? This frame would be distinct from standard frames in relativity, perhaps isolated or uniquely affected by these conditions. How might we approach defining and understanding such a frame, and what implications could this have for our understanding of spacetime and gravity? (Overlooking Synchronicity and Relativity: very unscientific/unhealthy approach) :I am wondering if it is possible to explore the idea for 'a Unique Frame of Reference'. This concept would revolve around the development of an 'Existence Function'. This function would emphasize the fundamental existence of entities over their synchronous events in spacetime. Instead of focusing on when and where events like the classic train-lightning scenario occur relative to each other, this function would prioritize the very existence of these entities or events as its primary attribute. The aim here would be to shift the focus from the relative timing and positioning of events to a more foundational level of their existence. Could this offer a new perspective in understanding the nature of reality, especially under extreme conditions like those in my hypothesis? Is it possible to reconcile such a concept with the established principles of quantum mechanics and relativity?" Spacetime Curvature at the Electron Scale: Considering the immense gravitational forces at play in my scenario, how might we conceptualize the curvature of spacetime at the scale of an electron? This question delves into the realm of quantum gravity – a territory where the classical laws of physics meet the probabilistic nature of quantum mechanics. Are there existing theories or models that could help us explore the behavior of spacetime curvature at such minute scales, particularly under extreme gravitational conditions?
  13. Nota Bene: I am not a mathematician or a scientist by profession. Instead, I am someone driven by curiosity, using various tools to experiment with speculative ideas and applying them to established equations in physics. My primary interest lies in the philosophical implications of these explorations and the thought process. I find that the realm of physics provides a fascinating and rich landscape to go into these ideas and to explore the deeper questions about existence and the nature of reality. I hypothesize that if space and time are intrinsically linked (as general relativity suggests), then any extreme effects on time, such as negative time dilation (?!), could imply a 'rupture' or dramatic change in spacetime structure. This speculation extends to consider the impact of such a rupture on the space component of spacetime as well. PS: Again, I didn't do the calculations.
  14. I am reaching out as a passionate enthusiast of theoretical physics with a deep curiosity about the fabric of our universe. Premise: My hypothesis is centered around the possibility that spacetime could undergo dramatic ruptures under conditions where an immense mass is concentrated into a scale as small as the classical electron radius, similar to singularity points in black holes. I am particularly fascinated by the idea that such spacetime ruptures could potentially trigger localized big bang-like events on the 'other side' of these singularities. Exploratory Thoughts: - Using the Schwarzschild and Kerr metrics, I've theorized how spacetime might react when an object with a mass 20 times that of the Sun is compressed into the scale of an electron. - This led to intriguing results, including negative time dilation values, which open the door to speculating about unconventional spacetime behaviors under these extreme conditions. - Could these spacetime ruptures be a gateway to understanding the initial conditions of our universe? Might the remnants or 'echoes' from such explosive events provide clues, suggesting that time could have behaved bidirectionally at the Planck moment? Speculation: While I am fully aware that these ideas are highly speculative and extend beyond the current empirical frameworks of physics, they represent a conceptual exploration into the mysteries of the cosmos. The notion that bidirectional time at the Planck moment could be linked to remnants of past cosmic events is particularly fascinating and something I am eager to explore further. Seeking Expert Insights: - With the Schwarzschild and Kerr metrics applied to an object of such immense mass at the scale of an electron, my calculations led to negative values in time dilation. How would you interpret these negative values in the context of these metrics and the given extreme conditions? - Does this theoretical approach to understanding spacetime at quantum scales resonate with current scientific thought, or does it conflict with established principles? - Regarding the possibility of spacetime ruptures leading to localized big bangs and the implication of bidirectional time at the Planck moment, what are your thoughts on these speculative ideas and their potential impact on our understanding of the universe?
