The most used hypothesis of formation of the universe is totally INCORRECT .
Why ??
This is is because if there was no matter, material , enegy and time before big bang theory how did the Big Bang Happen .
A alternate theory by myself .
GalaxCollider
As we. all know that Earth is 4.5 billion years old.And in the coming 4.5 billion years Andromeda and Milky Way are going to collide which mean a super black hole would be created. And there would be a nee formation of the planets
So if we look in the past there are chances two galaxies would have collided to create a black hole which in itself corrupted and formed the milky way ( Lets name the Galaxies

You're looking at the situation from the point of view of classical physics. The big bang event was quantum mechanical in nature and involved Heisenberg's Uncertainty Principle: measurements such as position and momentum can never be determined to an arbitrary degree of certainty. Perfect vacuums can never be created. Volumes of space with zero energy can never exist. You can never have a temperature of absolute zero. There is always an uncertainty in the value of these measurements and the uncertainty of the value has absolutely nothing to do with how accurate the measurements were or if better instruments could be created. It is built into the fabric of reality. Thus the big bang event could occur. Neither time nor space existed prior to that particular roll of the quantum dice. There it was; spacetime and mass popped into existence. There is no classical explanation for this. It is entirely quantum mechanical in nature.
In this "quantum dice" analogy there's nothing that eliminates the possibility that god plays quantum dice with a 10^100 (a google) sided die. Every billionth of a second he rolls the dice and with every roll a new universe pops into existence. However, the laws of physics aren't quite right in this new universe and a billionth of a second later it collapses back into nothingness. Over and over he rolls the die until he finally rolls 00. 00 is the one and only roll that creates a stable universe - the one we live in. How long did this take? Forever. It took forever. The idea of time when there is no spacetime fabric is meaningless.
The Uncertainty Principle is real, not just a theoretical construct. If it were not real we would not be here to contemplate its merits because the stars themselves would not exist. No stars, no elements other than hydrogen. The center of stars, hot thought they might seem at tens of millions of degrees, are far too cold to fuse hydrogen to helium. The uncertainty of position when protons (hydrogen nuclei) approach each other allows them to occasionally "go around" (quantum tunnel) the repulsive Coulomb Force and fuse into helium-2, deuterium and helium-4 and release positrons, neutrinos and a huge amount of energy.
How big is the universe "really"? We don't know and never will. For a somewhat short period of time after the big bang the universe expanded at greater than the speed of light. No mass was moving at FTL. Spacetime itself was expanding - the "squares on the grid" got bigger, things embedded into the grid got farther apart but they didn't move faster. So now there is an event horizon some 16 to 19.5 billion light years distance beyond which the light from the outer region that experienced the super expansion will never reach us. It is traveling toward us at light speed but the spacetime in which it was created is expanding and moving away from us at many times the speed of light.
Excuse the use of the present tense "is expanding". It's awkward to use the past tense and still convey the message because this event occurred 16 to 19.5 billion years ago but we are seeing evidence of it today. The light from the visible edge of the event horizon is just now reaching us.
BTW: How does the ultimate collision of Andromeda and Milky Way become an alternate to the Big Bang? We already have a supermassive black hole at the center of the Milky Way that has about 4 million solar masses. It is believed that most if not all galaxies have a supermassive black hole at the center. It's still theoretical but the physical evidence is mounting through direct observation.
When we merge with Andromeda the two galaxies won't explode. Sure, lots of stars will form new binary, but binary star systems are the rule, not the exception. Astronomers estimate that single star systems like ours comprise only 1% to 15% of all star systems.
Anyway, the mean free path for the stars as the two galaxies merge means head on collisions will be very rare. We will probably have two supermassive black holes that could form a supermassive black hole binary and over time merge as the new super galaxy is formed. If you read some articles about what is going on at the center of Milky Way, you find that even there, where the stars are under the extreme influence of the gravitational field of the supermassive black hole in an area where stars appear to be packed like sardines in a can (they aren't really) as they go literally whipping around the black hole they are orbiting - they don't collide.
"Mean free path" in physics is the statistical average distance particles can move through a substance before they collide with another particle.
