Question

How could the absence of gravity affect the formation of planets

Answer 1

It would be very chaotic... For example anything that was not attached to the Earth will probably go flying off into space in the straight linear line. if you're already disappeared the Earth's atmosphere would float in space so other planet's atmospheres would also float into space... planets will break apart into pieces and go off in space and planets are held together by gravity period. Imagine gravity is a string, once you look over that string or quote unquote "turn off" gravity, everything will go flying into linear lines on to the vastness of the cosmos. I hope this helps if you need any more examples for any other questions please let me know have a blessed day. :-)
