# Life in a random universe: Sciama's argument reconsidered

@inproceedings{Wang2021LifeIA, title={Life in a random universe: Sciama's argument reconsidered}, author={Zhi-Wei Wang and Samuel L. Braunstein}, year={2021} }

Random sampling in high dimensions has successfully been applied to phenomena as diverse as nuclear resonances, neural networks and black hole evaporation. Here we revisit an elegant argument by the British physicist Dennis Sciama, which demonstrated that were our universe random, it would almost certainly have a negligible chance for life. Under plausible assumptions, we show that a random universe can masquerade as ‘intelligently designed,’ with the fundamental constants instead appearing to…

### Cosmic Explosions, Life in the Universe, and the Cosmological Constant.

It is found that the authors seem to live in a favorable point in this parameter space that minimizes the exposure to cosmic explosions, yet maximizes the number of main sequence (hydrogen-burning) stars around which advanced life forms can exist.

### Anthropic bound on the cosmological constant.

- PhysicsPhysical review letters
- 1987

It is argued here that in universes that do not recollapse, the only bound on the cosmological constantlambda is that it should not be so large as to prevent the formation of gravitationally bound states, and it turns out that the bound is quite large.

It is suggested that the Fermi paradox is not a real problem or research subject and should not be used in debates about SETI projects, and it makes no sense either theoretically or empirically to separate the two.
