Imaginary Engine: Dark Matter & Super Symmetry Needed

AI Thread Summary
The discussion centers around the concept of an imaginary engine that requires a dark matter governor and a supersymmetric generator, both of which are currently non-existent. This engine is theorized to produce dark energy and gravitational radiation, although the implications of such radiation on the environment remain unknown. Additionally, Louis Crane's research on small black holes, funded by a grant from the Foundational Questions Institute, aims to explore their potential as energy sources for propulsion. The conversation also touches on the complexities and paradoxes associated with singularities in theoretical physics. Overall, the thread highlights the intersection of speculative engineering and advanced theoretical concepts in physics.

My dream engine, needs a dark matter governor to prevent it exceeding its designed rpm limit, unfortunately no one makes them yet.
It will produce dark energy as the motive power, but alas the formula for
its production, or its existence is not known.
It will, hypothetically, if it runs, produce gravitational radiation, as a by product, but as no one has identified it yet, it is not known if it will be damaging to the environment.
It also needs a supersymmetric generator, just to hold it all together, another yet to be designed component.
As my engine is imaginary, there is no way it will blow a gasket, so i hope
none of the possible buyers will :smile:

The University of Kansas quantum gravity theorist Louis Crane got a grant for a couple of million from the Foundational Questions Institute (a private outfit with Templeton money)

Can you guess what for?

I guess you know about black holes radiating. the smaller they are the hotter and the more they radiate. If you could make small enough black holes they would be glowing red hot, or even white hot.
Louis Crane has proposed to find out more about very little BH which he says could ultimately be used as a source of energy to propel spaceships and do other useful stuff like that:biggrin:

I wouldn't trade one Louis Crane for a million Brian Greenes.

Marcus, i refuse to think about the singularity any more, it throws up to many
paradoxes, if it/they are physical, then there could be no end to the complexity, of what should be a beautiful theory in the making.
 
Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Title: Can something exist without a cause? If the universe has a cause, what caused that cause? Post Content: Many theories suggest that everything must have a cause, but if that's true, then what caused the first cause? Does something need a cause to exist, or is it possible for existence to be uncaused? I’m exploring this from both a scientific and philosophical perspective and would love to hear insights from physics, cosmology, and philosophy. Are there any theories that explain this?
