Of course,energy forms like Light,sound do not have any connection with gravity.
Weight would not exist without gravity.
only when there is gravity present
The Earth continues to exist because of MATTER CYCLING, ENERGY AND GRAVITY
It can, and it does. There's no connection between the two.
Planet Earth, the Sun and stars, galaxies, ...
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
Without energy you cannot move,think or even exist, the sun wouldnt exist, nothing would exist.
In a star a balance exist between gravity shrinking and expansion due to fusion energy released.
Yes - there are many different types of energy.
There would be nothing to pull them together. Without gravity, we'd just be a bunch of atoms stuck in time. Or possibly not even that.
A biotic community can not exist without producers. This is because producers are the only source of energy from the sun.
Gravity is one of the 4 fundamental forces of the universe. Without gravity, nothing would exist. Nothing made gravity, and nothing can destroy gravity. So one answer to this intriguing question is: Before the first speck of matter.
