Is Big Bang theory false or real? Did the origin of universe come from the biggest Explosion ever? Check facts

‘Where did we come from?' It is one of the oldest questions in human history that every discipline of knowledge from philosophy to theology to science has tried answering. Today, the Big Bang theory is the most accepted explanation for the origin of the universe. However, some have called the Big Bang theory false. Sadly, theories are all we have since it is not possible to travel back in time and see how the universe actually originated. And since it cannot be proven, many have been led to question whether Big Bang theory is real or not. And if the universe did not really explode into existence, then how did it?

Scientific community is not very bothered with these questions. The major reason is that we already have seen evidence that is in sync with the Big Bang theory. And as we increasingly explore the far corner of the universe, we come across more such evidence. Recently, the NASA James Webb Space Telescope observed the oldest galaxy — GLASS-z13, that existed just 300 million years after the Big Bang — which points towards the red shift, another evidence of the Big Bang theory.

So, what is this evidence and what is the red shift? Let us break down the technobabble and explain these in simple terms.

According to the Big Bang theory, around 13.8 billion years ago, a the mother-of-all explosions took place in the dense structure of gasses and dust and that's how the first star formed and it started a chain reaction through which all the present stars, planets and galaxies were formed and that in itself created life somehow. The second part of the theory suggests that ever since the explosion took place, the universe is in motion and is expanding outwards — like how particles behave in an explosion.

Now, this is something
