If gravity is a function of mass, how can it exist before the big bang

hi dipayankar, well my thought is that gravity just before the big bang in a compressed state holds all the key ellements to creat a universe . compressed gravity comes to a point when all it can do is repulse its self. this force creats energy, matter , mass and then creats our laws of physics and time.

the hole universe compressed = gravity hmm or maybe antigravity
