AI Thread Summary
Gravity is described as a distortion of spacetime caused by mass, with both the Earth and the Sun influencing this "fabric." The Earth pulls on spacetime just like the Sun, which is why people remain anchored to the Earth's surface. The strength of gravity is determined by the mass of an object, meaning all mass affects spacetime. This leads to the conclusion that spacetime is indeed a property of mass. Understanding these interactions clarifies how gravity operates on Earth and throughout the universe.

Ok, so according to Einstein, the Earth is held in by a "fabric" due the the Sun pulling on said "fabric." So my question, what holds people on Earth if gravity is this "spacetime fabric?"

Hi Nickriener! :smile:

the Earth also pulls on the fabric. :wink:
 
not only Sun, every objects will pull on the fabric...Earth also unexceptional..so it depends on the size of the object to determine the strength of the gravity..
 
All mass distorts what you call “ space-time fabric”

So that means space-time is also a property of mass?
 
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.

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...
