AI Thread Summary
Gravity has minimal impact on nuclear reactions, including fission and fusion, as gravitational forces are significantly weaker than the nuclear and electrostatic forces involved. Historical nuclear tests in space, such as Starfish Prime, demonstrate that nuclear reactions can occur without the influence of gravity. The process of a chain reaction in fission relies on neutrons colliding with atomic nuclei, while fusion depends on high temperatures for nuclei to collide and fuse. Therefore, zero gravity does not hinder these nuclear processes. In conclusion, gravity does not affect the feasibility of nuclear reactions in space.

Will zero gravity effect the fission and fusion of the atoms making a chain reaction impossibile
 
Astronomy news on Phys.org
No.

Nukes have been tested in space before:

There were also fears by the United States that the Soviet Union would try to hide nuclear tests on the far side of the Moon.

The presence or absence of a gravitational potential field has virtually no effect on the progress of nuclear reactions, because the gravitational force is so many times weaker than nuclear forces that cause an explosion and the electrostatic forces that hold the device together.
 
chain reaction (fission) is dependent on the neutrons hitting the nucleus of the atoms then producing more neutrons, nothing 2 do with gravity...

chain reaction in fusion is dependent on high temperature (high kinetic energy) of the nucleus so they collide so hard that they fuse together... so also nothing 2 do with gravity...
 
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...
