Zeroth Law of Thermodynamics

AI Thread Summary
The average temperature of the universe is approximately 4K, which is significant in discussions of the Zeroth Law of Thermodynamics. The habitable range for life as we know it is between 273K and 373K, corresponding to the liquid state of water. This range defines the "Goldilocks zone," where conditions are just right for life. The percentage of the universe that falls within this temperature range is minimal, highlighting the vastness of inhospitable environments. Understanding these concepts is crucial for discussions about the potential for life beyond Earth.

Is there a set average temperature for the universe? And taking into consideration our habitable temperature is x being closer to y than z. If so where does zeroth law of thermodynamics fit?

x='s Earth's surface average temperature
y='s absolute zero
z='s surface of the sun

What percentage of the universe would be habitable solely based on temperature. A link will do, I've been trolling around thermodynamic web forums and the like...-Beastcloud

Well, 4K is a pretty good answer.

By "habitable" I will assume "life as we know it". If you wish to change that, you'll need to be more specific.

And with that assumption, the answer is easy: the liquid range of water: 273K-373K. This is is known as the http://en.wikipedia.org/wiki/Goldilocks_zone#Goldilocks_phenomenon".



But I'm not sure those are the answers you were looking for...

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
