AI Thread Summary
If Earth stopped spinning, the gravitational force would feel only slightly stronger, approximately 1.0035 times the current strength at the equator, which is negligible. The centripetal force from Earth's rotation is minor compared to gravitational force, calculated to be about 0.034 meters/second^2. However, the sudden halt of rotation would create significant inertial forces, potentially causing catastrophic impacts. The discussion humorously notes the dangers of such an event, likening it to slamming into a mountain at high speed. Overall, while gravity would increase slightly, the immediate effects of inertia would be far more concerning.

What would be the gravitational effects on people if this happened? I figure gravitational force - centripetal force = 9.8m/s^2... so is the gravitational force much stronger then 9.8?

You can see here that the formula for the centripetal force is F = mv^2 / r, so the centripetal acceleration would be v^2 /r. Here, v is the circumference of the Earth divided by the rotation period of the Earth (assuming you're standing at the equator), or 2*pi*r/(86400 seconds) , so squaring this and dividing by r gives 4*pi^2*r/(7.46496*10^9 s^2) = 0.034 meters/second^2. So, if the Earth wasn't rotating gravity would only feel about 1.0035 times as strong as it does now at the equator, not a noticeable difference.
 
Oh pff... guess i was wrong :D thanks!
 
Jesse has it right. The centripetal force due to Earth's rotation is minor compared to gravity. The inertial force, on the other hand, might be worrisome were the Earth to suddenly stop rotating. Buckle up. According to the Surgeon General, slamming into a mountain at ~1000 miles per hour can be hazardous to your health.
 

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...
