    Friction
AI Thread Summary
Meteors are not heated by friction in the traditional sense but rather through fluid drag as they interact with the atmosphere. The concept of air friction involves the "stickiness" of the airstream to the meteor's surface, which contributes to heating. Additionally, ram air pressure, caused by the meteor's high-speed entry, plays a role in this process. The discussion emphasizes the importance of understanding the physics behind meteors rather than relying on misconceptions. Accurate scientific explanations clarify the mechanisms involved in meteor heating.

It's a more correct statement
Air friction is strictly fluid drag where there is an interaction between the air and the surface of the body - and so the 'stickiness' of the airstream to the body matters.
Ram air pressure is just hitting the air molecules in front of you at high speed - it's still what you would think of as 'friction' in common terms.
 
That claim is absurd, Try science, not fiction. The physics behind meteors is sound. No need for 'spooky' physics.
 
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.
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.
