Is all that exists just whatever exists right now? Is the past erased and the future a void yet to be filled? Well, the answer lies in between the past and the future – in the elusive, ever-moving eye-blink that we call the present.

@homergee3381
03/08/2025 - 1:13 PMIs the measurement of a moving object an actual thing or is it just a measurement? If like me, length or weight or temperature are just measurements like time and don't actually exist outside of the mind then past and future don't exist outside the mind either. The flow of time for an object is the opposite definition of the fixed time of an object but with careless disregard scientists continue to use the terms interchangeably, time is either fixed for each object or flowing for each object, it can't be both so whenever a scientist talks about a fixed moment in a flow of time they make you dumber.

@DonCarlos590
03/08/2025 - 1:13 PMDoesn't mass or affect time? In other words your very existence in the universe helps move time and therefore creates a larger universe. If you was the famous illusionist David Copperfield and make a planet disappear the total mass of the universe would shift. Probably not much given it's size in relation to space
@alexcunhapinto
03/08/2025 - 1:13 PMHelp me out. Matt said 'observed', but did he mean 'interacted'? Quantum physics had a long time before being 'observed' by any species. Or do we fall into solypsism and could argue that the only reality is nmy head? Or yours? Or all at the same time? Arrrrgghhhh!!!

@rigisrs7506
03/08/2025 - 1:13 PMIf somebody can watch our earth planet full off moving dinosaurs from 100mln light years away that means past still exist. From their perspective future exist becouse off the observer . If I watching you with binoculars from a distance you exist?- yes!
Sorry for my grammar and childish view

03/08/2025 - 1:13 PMThe Block Universe, UAP Disclosure and Time travel:
1. They've been here for a really long time, reportedly around 145,000 years, but they don’t reckon to be our creators.
2. They come from the constellation Libra. Their home star system is older than Earth (7.21 billion years old), and is located ca. 74 light–years away. The identity of their home star isn’t confirmed, but it's suspected to be a G-type, Sun-like star such as KU Librae or possibly 23 Librae.
3. "The Greys" are artificial bio-robots assigned to do the dirty work. If needed, they can be sacrificed to draw humans' attention, allowing the real extraterrestrials to remain hidden.
4. Their physical appearance resembles that of a demonic figure, and is similar to the main "Uber-Morlock" character in the 2002 movie The Time Machine. They also have vertical pupils, much like a cat’s.
5. It's speculated that they consume human flesh.
6. They "have control" over the CIA, whatever that means.
7. MK-Ultra was inspired by these beings, and is still active today. One of its hallmarks is a sound similar to a buzzing bee. Everyone is advised to check the area behind their right or left earlobe for any foreign objects.
8. The communication through MK-Ultra works like this: You ask a question (telepathically) in your own language, they understand it in theirs, and you receive the answer in a way you can understand (such as text or drawing appearing on your skin, usually on your hands).
9. The 47th and 49th TAC Bases.
10. Time travel to the past is possible, and the Block Universe theory holds true. We're living in time-looped reality, with evidence that’s been apparent for over 40 years (K. Wilde, Hollywood, S. Vega and Poland due to the Polish-American time traveler). The past and future interact with each other, functioning simultaneously as both cause and effect. The technology enabling time travel originates from these beings.
11. The 1980s trilogy Back to the Future is a coded description of the real Polish-American time traveler, born in the 1990s, and his life within the closed timelike curve in the 21st century.
12. The real Kyle R(i)eese:
91.7.09 – 79.26.10 (12).
He probably arrived in May 1977 and died on 26th October 1979 in UK (the original love story between the British singer K. Wilde and the Polish-American time traveler).
13. The oldest known civilization in the Milky Way is said to have existed ca. 7 billion years ago, over 800 light–years away in the constellation Capricornus (or possibly Aquila). The distance is reportedly as much as 989 light–years. This civilization no longer exists, but the cause of its extinction hasn’t been disclosed.
14. The explosion of Betelgeuse as a supernova is reportedly to occur in 203 years.
The above information comes from communication with several of them via MK-Ultra.

Free will in the Block Universe within closed timelike curves (CTCs):
The idea that the universe functions as a Block Universe, where time exists as a unified, predetermined structure, and the possibility of closed timelike curves (CTCs), carries not only fascinating theoretical implications, but also profound consequences for how humans perceive reality. Below is an expanded exploration of these effects on individuals and society.
1. Perception of time and reality:
a. Reality as a frozen whole:
If time isn't linear, but exists in its entirety (like frames in a movie that can be viewed at any moment), our intuitive understanding of reality would undergo a complete transformation. Instead of experiencing the present as the only "real" moment, people might learn to think of the past and future as equally existent. This could alter the emotional experience of life – potentially reducing fear of loss, but also challenging the significance of the "here and now."
b. CTCs and cyclicality:
If the universe operates through time loops, not only individual events but entire lives might repeat endlessly. This could lead to extreme reactions, from fatalism to acceptance, or even fascination with eternal recurrence. People might also focus more on the quality of their lives, knowing they will live them repeatedly.
2. Free will and sense of agency:
a. Illusion of free will:
In a deterministic universe, every choice would be less a "free" decision and more a consequence of prior conditions. For many, this might be liberating – removing the burden of responsibility for decisions – but others might feel deeply disheartened, perceiving themselves as "puppets" in a grand cosmic theater.
b. Free will within constraints:
However, if within a closed timelike curve we can make decisions that must align with future events, free will might be reinterpreted. It would be a constrained will; something that seems free at first glance, but ultimately adheres to the rules of temporal consistency.
3. Morality and ethics in a deterministic world:
a. Reevaluating responsibility:
If everything is predetermined, the concepts of guilt and merit might need to be reconsidered. For instance, can someone be blamed for a crime if it was destined to happen? New ethical frameworks might emerge, focusing more on understanding human actions than on judging them.
b. Morality in a loop:
In a scenario of eternal recurrence, people might question whether their actions hold universal significance or merely local relevance in a given cycle. This could lead to a heightened sense of responsibility, emphasizing the value of every decision as potentially eternal.
4. Impact on psychology and everyday life:
a. Existential crisis:
For some, the vision of having no real influence on the course of events could provoke a profound existential crisis. Questions about the meaning of life, actions, and emotions might become even more pressing.
b. Sense of reassurance:
On the other hand, knowing that everything happens according to a "preordained plan" might be comforting. People might find solace in the stability and unchangeability of their place in the universe, reducing fear of the unknown.
c. Increased mindfulness:
In a deterministic world, individuals might learn to appreciate the present moment more, understanding it as an integral part of a greater whole that cannot be altered.
5. Education, science, and culture:
a. New understanding of time:
In a society aware of the Block Universe, education might shift towards teaching about the non-linear nature of time. Science could focus on exploring temporal structures and the possibilities of utilizing them.
b. Time travel technologies:
If CTCs were practical, it could lead to a societal revolution. The ability to return to the past or travel to the future could affect every aspect of life. On the other hand, if CTCs assume a deterministic nature of the universe, time travel wouldn't involve changing the past, but fulfilling events already set in motion. In such a model, travelers to the past wouldn't alter the course of events in a way that contradicts what has already happened, as their actions would inherently be part of the same timeline.
○ No time paradoxes:
This approach resolves classic paradoxes, such as the "grandfather paradox," because the actions of the time traveler must align with events that have already occurred.
○ Fulfilling a role in history:
Time travelers could become witnesses or participants in past events, but only in ways that are already accounted for in the temporal structure. For example, they might turn out to be "unidentified figures" in historical incidents but wouldn't alter the outcomes.
○ Limited social impact:
In terms of personal choices and historical events, time travel would be more about observing and understanding what happened rather than actively reshaping reality. This might limit the scope of potential societal revolutions, as time travel wouldn't be used to manipulate events, but rather to "experience" them in a predetermined way.
c. A new perspective on society:
Despite these limitations, practical CTCs could still influence society by introducing new possibilities:
○ Revolutionizing historical studies:
The ability to travel to the past could transform history and archaeology, allowing for precise verification and documentation of events.
○ Enhanced self-understanding:
Traveling to one’s own past could provide insights into personal decisions and the context in which they were made.
○ Technological challenges:
The development of the technology to enable such travel could lead to massive scientific and technical breakthroughs, regardless of deterministic constraints.
7. Impact on religion and spirituality:
a. A deterministic divine plan:
Religions might adapt their teachings, viewing the deterministic universe as a manifestation of divine will. "God as the architect" could take on new meaning, and questions about free will could be integrated into theology as mysteries to be accepted.
b. Reinterpreting death:
If time is cyclical or exists as a unified block, death might lose its traditional meaning. Instead of being an end, it could be seen as a transition to another point within the never-ending structure.
The acceptance of the Block Universe theory and the concept of CTCs could change our understanding of life as profoundly as the Copernican or Darwinian revolutions. This worldview wouldn't only require new philosophical frameworks, but also psychological adaptation. It could lead to greater acceptance of reality while raising fundamental questions about the meaning of existence that we are only beginning to explore today.

@Sebastiaan_Y
03/08/2025 - 1:13 PMI wonder if we can calculate what percentage of reality is simulation.
@JayDeePLUS-BEATZ
03/08/2025 - 1:13 PMLet's take it deeper. The faster you go the slower time moves. So, it's possible that at the rate of speed we are moving compared to other objects , that the future has already happened we're just moving to fast to observe the future. The past is currently happening it's just happening slowly because of the rate of our speed the earth is traveling in. The past, present and future is all happening at the same time , the big bang is currently happening and the end of the universe at the same time we are just trapped in gravity wells while traveling some percentage of the speed of light
@richardmannarino9379
03/08/2025 - 1:13 PMI agree. Lol…
@celiogouvea
03/08/2025 - 1:13 PMFrom what I understand, based on the theory of relativity, everything we see exists in another dimension, with light and the fundamental forces shaping the reality around us. This could mean that our spacetime originated from the collision of two energy fields that blend at different rates at each point in the universe, thereby stabilizing matter. I propose that the interaction of these two energy fields surpasses the speed of light, making the past and future inaccessible. This is because our reality transcends faster than the speed of light in relation to the past, just as the future transcends our present. Therefore, light becomes reality as dimensions split, transcending all dimensions, and it becomes real to us only when it reaches our eyes.
@brassj67
03/08/2025 - 1:13 PMRemember, tomorrow never comes.
I personally can't imagine that the past and future don't already exit. It doesn't make sense to me that they wouldn't.

03/08/2025 - 1:13 PMYes. Yes it does.
@subculture-records
03/08/2025 - 1:13 PMWould time exist if humans didn't? Time is a human unit of measurement, that's all. We feel the need to measure the reality which surrounds us. A better question would, perhaps, be… is reality real?

03/08/2025 - 1:13 PMHey, wrong question! Of course the past exists. I mean, I can show you the books. And, of course the future by definition does not exist, yet. The pertinent question is, “Does the present exist?” If it does, I’d sure like someone to point it out to me.
