If You Stop Time, God Dies

A conversation that started with gold mining and ended somewhere else entirely.


My oldest son sent me a slide. It was part of something he'd been working through — a philosophical framework about the relationship between time, space, and matter. Clean, logical, structured. His mind works that way.

The slide argued that time is codependent on matter and energy, not on space. That without change there is no time, and without matter and energy there is no change. Therefore time only exists where matter and energy exist. Space without matter is timeless. Time without matter is impossible.

I read it. And then I got stuck. We laughed about that on the phone. 

Not on what the slide said. On what it implied if you pushed it one step further.

Was it because I'm 70? Learned about this stuff in the way of absolutes in the 1960s and 70s? And 80s when I graduated university after the USAF? Did I just need time to assimilate it all?


What If You Stopped Time Everywhere?

The slide stops at a logical but comfortable place. I couldn't.

If time requires matter and energy, and space is essentially a container for matter and energy — what happens to the container if you freeze everything inside it? Not locally. Not in one corner of the universe. Everywhere. Completely.

Space isn't what most people think it is.

We picture it as an empty stage, pre-existing, waiting for matter to show up and perform. But that's not what general relativity describes. Space — spacetime — is dynamic. It curves and bends and responds to matter and energy. It is in some fundamental sense defined by matter and energy, not separate from them.

So if you freeze time everywhere, you don't get an empty universe. You get an undefined one. The relationships that constitute space dissolve. The container doesn't empty. It ceases to be a container at all.

Space doesn't go dark. It goes undefined.


The Restart Problem

Here's where it gets truly unresolvable.

If time stops completely and space collapses with it — can it restart? Not like in movies or sci fi, but really.

No. And not for a complicated reason. For a devastatingly simple one.

Restarting requires a before and an after. That's time. To restart time you need time to already be running. You cannot bootstrap sequence from a state of perfect frozen stillness. There is no edge to grab. No outside mechanism still ticking. No unpause button that exists anywhere, because "anywhere" no longer exists either.

A universe with time stopped everywhere is not a universe on pause. It is indistinguishable from a universe that never existed. Not darkness. Not cold. Not silence. The complete and permanent absence of the category of anything happening.

That is the most honest description of true nothingness I've been able to arrive at.


Could Time Exist Without Space?

Before we get to God, there's one more turn.

If you freeze time and space collapses — could time still exist somehow, outside of space? Untethered from the container it apparently requires?

Maybe. If time is fundamentally about sequence — about A preceding B — then it doesn't strictly require a where for that sequence to occur. Some physicists, Lee Smolin among them, have argued that time is the most primitive thing in the universe. More primitive than space. That space itself emerges from relationships between things over time.

If that's true, time without space isn't impossible. 

It's just incomprehensible to minds built inside space. Pure sequence. Pure before-and-after with no here-and-there. Causality running in a void that isn't even a void because void implies extension.

I can't quite visualize it. But I've stopped confusing my inability to visualize something with its impossibility.


Now Consider God

If God exists — and I'm not arguing either way here — then God exists somewhere in relation to time. Either within it, alongside it, above it, or as its creator.

Genesis says God created time. 

But Genesis was written by people doing something deeply human and deeply necessary — building a frame for existence to replace far worse frames. The void is terrifying. 

"In the beginning God created" is a psychologically brilliant answer to that terror. It says there is an author. Therefore meaning. Therefore your life is not an accident in a cold indifferent dark.

That's not nothing. It held civilizations together for millennia.

But it was never built to survive the question we're asking now. And the sadness in that construct is that it was a placeholder for the lack of something, that turned out to be -- Science. Once science arrived on the stage, religion should have bowed out. But it did not. Instead, religion (or those who support it and the power and wealth they maintained FROM it) murdered people to maintain and retain its existence, far beyond, even unto today, its need to exist.

If time stops everywhere — if the terminal condition I described above occurs — God stops. Not sleeps. Not waits. Stops, in every meaningful sense. And if time cannot restart, God cannot restart. The same logic that traps everything else traps God too.

Which means one of two things:

God is time itself. 

Not a being who created time or lives within time, but the process — change, sequence, causality — that is the divine. 

Spinoza circled this. 

Process theology circles it. 

Most mystics across most traditions have sensed it without quite having the vocabulary. If this is true, God doesn't stop when time stops. God is the stopping. God is the running. God is the before and after, not a thing that exists between them.

Or God is subject to time like everything else, which means time is the more primitive thing. Time doesn't need God. God needs time. And Genesis, whatever its beauty and utility, has the causality exactly backward.

Neither option is comfortable. The first makes God so abstract as to be unrecognizable to most believers. The second subordinates the divine to a process that has no author and no purpose. 

But perhaps "God" is just anthropomorphized constructs to begin with.


Where That Leaves Us

Here is what I think the honest position is, arrived at through a conversation that started with a slide on a phone screen:

If time is the most primitive thing in existence — more fundamental than space, than matter, than energy, than any being however vast — then existence itself is stranger and more vertiginous than any creation story can hold.

Genesis isn't wrong because it's stupid. It's insufficient because it's human. It was built from fear, not from physics. For comfort, not for rigor. And there is no shame in that. Humans needed it. At the time.

But if you follow the logic without the safety net — no author, no frame, no reassuring beginning — you end up somewhere that most creation stories can't follow you.

Time may be the only thing that was never created.

Which means it may be the only thing that was always, in whatever sense "always" can mean when time itself is what you're talking about, simply there.

Not God. Not nothing. Just the irreducible fact of sequence itself, from which everything — space, matter, energy, life, thought, this sentence — eventually and improbably emerged.

That's either the most terrifying thing imaginable.

Or the most interesting.

I know which one my son would say. I think I know which one I'd say too.

This wasn't meant to be a perfect consideration here, but a consideration nonetheless, to evoke thought. 

Something religion refused to do for millennia. 

And we now have the freedom to...

Why is SpaceX using giant arms to catch returning landing spacecraft?

I've been talking to ChatGPT again, kicking around how to make it useful for me. For some things, it IS very useful, for others, it's utterly useless. It just takes getting used to it, playing with it, and maybe finding one you feel comfortable using. So today I got onto this topic, about the big SpaceX grab. I was interested to hear what it had to say.

If you were wondering what the big deal is about SpaceX catching a landing rocket, so was I. I got it, but I wanted to know more.

I think I only wrote one spaceship story, "Expedition of the Arcturus", about Earth's first 75-year-long journey, generational spaceship. Told in reverse timeline. First published in PerihelionSF hard sci fi magazine. I got "Arcturus" from David Lindsay's A Voyage to Arcturus (1920).

I asked:

SpaceX recently caught a very large rocket on reentry at the platform it arrived at which caught it with two arms. Why catch it? Considering they already have proven they can land boosters on water barges how is this an advancement?

Republic TV (India)


ChatGPT said:

SpaceX's recent achievement of catching a large rocket during reentry using a platform equipped with two arms represents a significant advancement in several ways:

  1. Precision Landing: While SpaceX has successfully landed its Falcon 9 boosters on drone ships at sea, capturing a rocket using a platform with mechanical arms demonstrates a new level of precision in landing. This capability could potentially allow for more accurate and controlled landings on solid ground, which could be crucial for future missions.

  2. Resource Efficiency: Landing on a platform on land can reduce costs associated with using drone ships. It minimizes the need for extensive maritime operations, reduces wear and tear on the drones, and can shorten turnaround times for rocket reusability.

  3. Increased Payload Capacity: By catching rockets at a platform, SpaceX may be able to develop larger rockets with increased payload capacities. This is essential for ambitious missions like Mars colonization or larger satellite deployments.

  4. Safety and Reliability: Catching a rocket with arms could provide a more secure method of retrieval than landing on a moving drone ship in the ocean, which is subject to variable sea conditions. This method could enhance the reliability of the landing process and further improve rocket reusability.

  5. Future Innovations: This achievement may pave the way for new designs and technologies in rocket recovery and landing systems, potentially leading to innovations that could be applied to other aerospace endeavors.

Overall, while SpaceX has already demonstrated impressive capabilities with drone ship landings, this new method of catching rockets on land represents a progressive step toward even more efficient, reliable, and ambitious space operations.

I said:

It seems a bizarre and kludgy process rather than simply landing not on a barge but on solid land, as Russia does.

ChatGPT said:

You raise a valid point. From an outsider's perspective, the use of mechanical arms to catch rockets in mid-air can seem overly complex compared to traditional landing methods. Here are a few reasons why SpaceX might pursue this approach, despite the apparent simplicity of landing on solid ground like Russia does:

  1. Complexity of Rocket Design: SpaceX's rockets, particularly the Starship, are designed for high-performance reusability, which includes the capability to be recovered in a controlled manner. Catching the rocket with arms can minimize the stresses and potential damage that might occur during a hard landing, especially if landing gear is not designed for solid ground recovery.

  2. Versatility: The arm-catching method allows for flexibility in landing zones. SpaceX often launches from sites where solid ground landings might not be feasible due to surrounding infrastructure or geographical constraints. This method could potentially allow recovery in diverse environments.

  3. Controlled Environment: Landing on a barge allows for a controlled environment in terms of timing and conditions, which can be more predictable than solid ground recovery, where factors like wind and weather can affect precision.

  4. Safety and Recovery: Landing on a barge at sea has the added benefit of reducing risks associated with populated areas. By utilizing barges, SpaceX can mitigate safety concerns related to rocket recovery and avoid the possibility of rocket debris impacting residential or commercial areas.

  5. Research and Development: This approach could be part of SpaceX's broader R&D strategy, allowing them to experiment with different recovery techniques. Innovations in rocket recovery may lead to more effective methods in the long run, even if they seem bizarre now.

While it may appear more cumbersome than conventional methods, SpaceX's catch system aligns with its vision of maximizing rocket reusability and efficiency. Ultimately, the effectiveness of this approach will become clearer as SpaceX continues to refine and deploy its technology.

Atomic Rockets

I said:

Yes, but as a rocket that can take off and land, and take off again as has always been exemplified in science fiction, as in using a plane or a car, in the air or on the ground, seems perhaps a more expensive and longer-term and reasonable path to follow. To get it over with, until a vehicle is fully compatible with space travel, otherwise having barges to land on, or arms to catch rockets, is delaying the inevitable need.

ChatGPT said:

You make an insightful observation about the potential benefits of developing fully reusable space vehicles that can seamlessly operate in both atmospheric and space environments, much like planes or cars. The concept of a rocket that can take off, land, and take off again without the need for complex recovery systems aligns with the long-term vision of many in the aerospace industry. Here are a few considerations regarding your points:
  1. Ultimate Goal of Reusability: The ideal scenario is to create spacecraft that can operate more like conventional aircraft, allowing for frequent and economical access to space. This would reduce reliance on complex recovery systems like barges and mechanical arms, ultimately streamlining operations.

  2. Technological Maturity: Achieving a fully reusable space vehicle that can operate like an airplane requires significant advancements in materials, propulsion, and control systems. SpaceX, for instance, is making strides with Starship, which is designed to be fully reusable for various missions. However, such technology is still in development and may take time to mature.

  3. Current Practicalities: While the long-term vision is clear, the current technology landscape necessitates incremental advancements. SpaceX's methods, including barge landings and catch arms, may be interim solutions to achieve reusability and cost-effectiveness as the technology evolves. These methods allow SpaceX to test and refine their systems in real-world conditions.

  4. Lessons Learned: Each step taken by companies like SpaceX informs future designs and methods. The experience gained from using recovery barges and arms could contribute to developing better landing technologies that can ultimately lead to the fully integrated systems you envision.

  5. Investment in Research: Funding and time dedicated to developing fully reusable vehicles are significant. The complexity and expense associated with designing a rocket that can perform as a multi-environment vehicle may deter some companies from pursuing this route initially, especially if they are still trying to demonstrate basic reusability.

In summary, while the concept of a fully integrated spacecraft that can take off and land like an aircraft is appealing and seems more efficient, the current path of using recovery systems allows for iterative progress toward that goal. Over time, as technology matures and lessons are learned, we may see developments that align more closely with the vision of seamless space travel you describe.

I asked:

But aren't the Russians already doing this?

ChatGPT said:

Yes, the Russians have developed and operated vehicles that exemplify the concept of reusability and multi-environment operation, particularly with their Soyuz spacecraft and the space shuttle-like Buran program. Here are some key points about their approach:
  1. Soyuz Spacecraft: The Soyuz has been used for decades to transport astronauts to and from the International Space Station (ISS). While it doesn't operate like an airplane, it is designed to be reusable. The spacecraft descends through the atmosphere, using parachutes to land safely on solid ground. Its design allows for relatively quick turnaround times for subsequent missions.

  2. Buran Shuttle Program: The Soviet Union developed the Buran shuttle as a response to NASA's Space Shuttle. Although it only flew once in 1988, the Buran was designed for fully autonomous flight and landing, demonstrating the capability for reusable spacecraft. However, the program was ultimately canceled due to funding issues and the dissolution of the Soviet Union.

  3. Multi-Environment Capability: The Russian approach emphasizes simplicity and reliability. While they may not have a fully reusable rocket that can launch and land like a plane, their vehicles are designed for effective operations in both space and atmospheric conditions, focusing on mission success and crew safety.

  4. Current Developments: Russia has been working on new spacecraft, such as the Oryol (Eagle) crew vehicle, which aims to enhance their capabilities for future missions to the Moon and beyond. The focus remains on developing systems that can operate reliably in a variety of environments.

While Russia's approach may differ from SpaceX's innovative methods, they have certainly made strides in the direction of reusability and adaptability in space travel. However, SpaceX's emphasis on rapid reusability and cost reduction has pushed the boundaries of what is currently possible, aiming for a more commercialized and frequent access to space. Each nation's methods reflect different technological priorities and capabilities, shaping their unique paths in the space race.

OK then. So there it is...

Expedition of the Arcturus - SF World Premiere on PerihelionSF.com

Today will see the world premiere of my short Science Fiction story, "Expedition of the Arcturus" (free) on the great new little Internet magazine, PerihelionSF.com.

I wrote this story just shortly prior to the meteorite and asteroid events of early 2013. When the meteorite struck Russia, I had already submitted my story to the editor, Sam Bellotto. PerihelionSF.com already has published a two part review I wrote on the fascinating documentary, "Chasing Ice" from when I attended its Seattle premiere. It was an amazing night and I invite you to read the review if you already haven't. The review has slipped off the magazine site as there is a more current issue online now. However, I'm looking forward to it being made available again soon as there are plans to bring archives of these writings back to the public:

"Some older stories are already archived by their respective authors. There are plans to also have a "Perihelion" archive of selected stories and articles. Stay tuned." - The Editors March 1, 2013

In "Expedition of the Arcturus", I had wanted to tell the story of a group of individuals who leave Earth on a mission with the highest of concepts, to assure the reach of Human Beings out into the Universe. While having made the decision for their as yet unborn descendants, who will become the first true Earth Citizens of Space, how will they handle their situation? What choice would they have? Will they ever make it to their final destination?

I also liked exploring the juxtaposition of truth and compassion, against that of political expediency and ethical genetic concerns. I played with the chronology of the story in a way that seemed to be the most effective method to bring the central theme of the story  to the forefront and with the greatest impact.

I hope you like it.
