THE BIG BANG THEORY - PART 2

 The mystery of our expanding universe

🌏🌎🌍

  

The expansion of the early universe is adequately explained by the big bang theory. That the explosion started it all from a single point of singularity, Until everything that exists now Because of the big bang theory, it is thought that the expansion of the universe will eventually slow down. Due to the attracting aspect of gravity, The gravitational attention from the stars and galaxies So, until recently, all evidence supported this accelerated expansion without any exception. This theory was supported by observations such as the CMBR (cosmic microwave background) and red shift galaxies. However, in 1998, two research groups from the Berkeley Lab and the Supernova Cosmology Project found something strange. As expansion can't be observed directly, they look for other effects caused by expansion and deduce the expansion speed based on the observations. Both teams independently discovered that a distant supernova appeared to be dimmer than expected by using reliable data from all over the skill. Keep in mind that the farther away an object is, the longer it takes its light to reach us. So that means the supernovas are further away from that expansion and have travelled a longer distance before reaching us. The researchers claimed that when they look at their objects, they look further into the past to about 7-9 billion years ago.

The funding shattered the previous theories of slowed expansion. Which would mean that the universe's expansion is accelerating instead of slowing down. And just recently, in May 2018. A reacher team from the DARK ENERGY survey has released the largest map. So far, it looks something like this. This discovery continued to support the change in expansion rate with a rather surprising twist: 

Their charges are accelerating over time. Yes. It was all happening regardless of the effects of gravity. We can see it accelerating in physics before according to what we know. All of this rumination and theorising .

Why is the universe expanding ?

It's critical to first understand what caused the expansion. The scientific consensus so far is due to the mysterious  DARK ENERGY

that permeates nearly all of space. Of course, the term "dark" doesn't really imply that it's dark at all. It's just called "dark energy" because no one knows what it is or where it comes from. We can't ever see it directly, since light can't travel through such a dense and pervasive field. Unlike normal matter, it just doesn't behave like anything physicists know about. Also, the name implies this, like gravity or radiation, but in reality, there isn't any physical evidence for this.

When you really dig deep into the theories, there's no way dark energy can interact with matter or radiation. It just operates in a completely different manner.

That's why some researchers are calling it "Phantom Energy". Dark energy was created further apart from each other as time passed following the movement of the big bang theory. The expansion of dark energy is constant, but it happens much faster than other
