what if before the big bang there wasn't nothing but everything was in perfect balance like a huge cloud of matter spread evenly throughout the universe and with little movement and something disrupted the balance or changed the energy keeping it in balance and matter started clumping together in a snowball effect and it spun out of control causing a massive influx of all the matter in a short period of time to get pulled in by gravity and then when the force was too great it exploded in what we call the big bang.
