THE BIG BANG THEORY -[the EXPANSION]......

 THE BIG BANG THEORY -[the EXPANSION🌍🌎🌏].....

When expansion seems to be much higher than expected for gravity and the density of the object, we call this effect "gravity enhancement ".The phenomenon was first discovered by NOBEL Laecreate, Sal Perlmutter astrophysicist Adam Riess and the supernova cosmology project. They found out that expansion is constant everywhere. These observations helped us understand the phenomenon of universe expansion as well as the nature of dark energy. But this finding still doesn't answer why expansion occurred in the first place. One popular speculation is that expansion happens due to a mechanism called vacuum metastability. It is an idea that expansion might be due to a universe being in a quantum fluctuation from nothing, our universe spontaneously popping out of nothingness. Perhaps expansion is an in-tolerance result of expansion itself that feeds on DARK ENERGY TENSION at this point.

THE IDEA OF AN ENDLESS UNIVERSE?

The concept of this accelerating expansion ultimately leads to  a new frame of reference in how we view the cosmos. And this idea is nothing less than the expansion of our universe without end. Consider the universe expanding indefinitely, with smaller and smaller galaxies moving apart from one another. Maybe the expansion will become weaker at some point. But in this case, it will never stop.

What would happen then if the expansion wouldn't pull everything back together?

We have no idea yet because our physical theories are not able to explain this phenomenon so far, but there are some possible outcomes, of course, with each through their case in detail

The case:-1 THE EXPANSION HALTS AT A POINT

It's possible that expansion will stop at a certain point because it becomes weaker over time as gravity becomes stronger. Gravity attracts, and expansion, of course, repels. It's like yin and yang. a cycle that is inextricably linked to one another one way, as gravity grows stronger, this could lead to everything falling back together into a MASSIVE BLACK HOLE from which no light could escape for eternity. And, even before that, what is left of our universe may collapse under its own weight as a result of all matter being crushed together so densely.

-2 EXPANSION IS SLOWED DOWN UNTIL GRAVITY OVERCOMES THE POWER OF EXPANSION

In this second case the expansion would become weaker and weaker until it was slowed down by gravity. At this point, the expansion would take over again, pulling everything back together only to be halted by gravity again. The cycle could continue forever until expansion becomes so slow that it can not overcome the strong pull of gravity. Both are constantly changing each other's power as cycles repeat themselves endlessly. In this case, there will never be an end to the universe from nothing as the old one becomes weaker. And this brings us back to the beginning of the expansion with no end.

Case 3: EXPAND FOREVER FASTER UNTIL ALL MATTER IS RIPPED AWAY INTO NOTHINGNESS.

Expansion is so powerful that it would simply overcome the pull of gravity no matter how hard gravity tries. This would result in the BIG RIP, a hypothetical future scenario in which the expansion would be so great that everything from atoms themselves would be ripe for oblivion. Nothing would stop expansion from taking over again and again. All matter and even space itself wouldn't survive beyond that point . Everything is moving away from each other at an even increasing speed until everything is ripped out of existence. This is truly the darkest time for us all.

Expansion that has no end
