AI Thread Summary
Inflationary Theory was initially proposed to resolve the Smoothness Problem of the universe. Recent observations of the Cosmic Background Radiation (CBR) suggest that the universe may not have been as smooth in its early moments as previously thought. The original model by Alan Guth has been challenged due to the "graceful exit" problem, which led to predictions of an inhomogeneous universe. Alternative models such as chaotic inflation, hybrid inflation, and supernatural inflation are now being considered. The ongoing debate highlights the complexities of understanding the universe's early conditions.

It was my understanding that one of the reasons for Inflationary Theory was to address The Smoothness Problem.

Haven't recent detailed surveys of the CBR shown that the universe wasn't smooth in it's first few moments?

Thanks,
Glenn

The original theory of Alan Guth is not longer valid because suffered of a problem called "graceful exit", and it predicted an inhomogeneous universe, rather that the homogeneous universe that we observe. Actually chaotic inflation, hybrid inflation or supernatural inflation are the references

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
