Particles, life, etc.
so does everything has mass?
Chronos said:... No gravity, no soup.
So I guess I'm saying that its unlikely to be able to have particles without some equivalent of gravity
Naty1 said:not likely so... because the very early universe was a charged particle soup, a plasma early on...so as things cooled, electromagnetic attraction and,say the strong force, would pull ions together to form particles...but after that not much would happen...hydrogen and helium might form,just a few simple particles, but gravity is needed to pull such inert gases together and provide the potential energy to get nucler reactions (fission/fusion) started... a few basic particles drifting far apart would seem to be rather inhospitable to the beginnings of life...
Thank you -- a very interesting point.malawi_glenn said:No gravitational attraction is not needed for Big Bang Nucleosynthesis. However, gravity is needed to stellar formation.
And God said -- Let there be General Relativity.Chronos said:Gravity is a given, life is not.

(sorry couldn't resist upon reading -- after the Douglas Adams quote.)
No, objects cannot exist without gravity. Gravity is a fundamental force of nature that is responsible for holding objects together and keeping them in motion.
While gravity is necessary for the development of objects on a large scale, there are other forces at play such as electromagnetism and the strong and weak nuclear forces. These forces can cause particles to come together and form larger objects, even in the absence of gravity.
If there was no gravity, objects would not be held together and would disperse into space. The Earth would not have formed and life as we know it would not exist.
It is unlikely that life, as we know it, could exist without gravity. Gravity plays a crucial role in the formation and maintenance of ecosystems, from keeping the Earth in its orbit around the sun to providing a stable environment for organisms to evolve and thrive.
No, gravity cannot be created or destroyed. It is a fundamental force that exists throughout the universe and cannot be altered or eliminated.
