Like.
It would have been nice if the article had described how contrails increase temperatures on the surface. There seem to be a lot of... -
Helio replied to the thread A Critical Examination of Cosmic Expansion and the Present-Day Origin of the CMB.Perhaps it helps to picture oneself at a time when all the emissions first took place. Prior to abut 380k years after the Bang, all...

Helio reacted to billslugg's post in the thread A Critical Examination of Cosmic Expansion and the Present-Day Origin of the CMB with Like.
The AI response is correct, except it does not address the amount of nonuniformity or the dipole non-uniformity. The CMBR is highly...

Helio replied to the thread Metaphysics..Yes, though is it more what science fiction does -- using the artistic license in assuming a future scientific answer -- thus avoiding...

Helio replied to the thread Metaphysics..Hmmm. "Why" questions are usually considered to be philosophical, or religious, questions. Metaphysics, IMO, still avoids such...

Helio replied to the thread Are we alone? Intelligent aliens may be rare, new study suggests.The clarify, there is a big difference between knowledge and truth. Knowledge is fact-based, it doesn't require a moral interpretation...

Helio replied to the thread A Critical Examination of Cosmic Expansion and the Present-Day Origin of the CMB.If DM is the source of the relic radiation, and because all radiation propagates through space, then only the local DM would give us...
