Beginning of the universe:
So many videos and write-ups on this subject. I don’t know where to start. How an ordinary person like me can write on this subject? So I tried to satisfy my obsession with just thinking. What is going to my mind I am writing below:-
Can this universe come from nothing? No, just as a baby can’t be born without the existence of the baby’s parent, or in vitro with the parents’ sperm and egg. So we have to ignore the concept of nothingness.
I am not a medical doctor but I know that conception needs a perfect pre-condition, similarly, the birth of a universe needs a perfect condition of gravity and fusion to the end of a universe (old one?) and the beginning of a new one (our universe).
Nothing comes from nothing. Then for something to exist, there must be something else available. Where did the material come from that created the Big Bang, and what happened in the first instance to create that material?
I just reiterate that statement. This is a perennial question. I realize that we just keep expanding our knowledge to get a better answer. There is no other alternative. I have looked at many videos and other resources for trustworthy answers from the angle of science and spirituality. I find a glimmer of faint hope from the cosmologist for better understanding and leaning more toward spirituality.
Death of the universe:
Is the death of a universe can bring the beginning of a new universe?
“The last star will slowly cool and fade away. With its passing, the Universe will become once more void, without light or life or meaning.” So warned the physicist Brian Cox in the BBC series Universe.
Is it that the fading of that last star is the beginning of an infinitely long, dark epoch? The last piece of matter, quark, and tiniest gravitation field will eventually be consumed by monstrous black holes, the last piece of photon gone and left with a void of dark space and dark energy. A fetus of a new universe taking shape for a perfect condition for a new baby universe. Embryo stages for a new universe could take trillions of years. Analogous to human death and rebirth we may accept it with a grain (cosmological error) of salt.
Death and rebirth could have been the source of another Big Bang like ours and the beginning of a new universe. Finally, a baby universe is born,
Frankly speaking, even if we believe in the rebirth of humans, there is no proof of the transitory long epoch, and similarly no proof of the death of the universe and its matter and rebirth of the new universe and its new matter. However, we must bestow trust in spiritual power for human birth, death, and rebirth. Modern astrophysics opened a clear horizon for a better understanding of the origin of the universe and powerful telescopes are proving philosophical thinking.
So let us fall back to the present understanding of physics.
The first real matter – let’s take a look at how the first matter came about. Origins of stable matter made of atoms or molecules were not around at the Big Bang instant, even not around hundreds of thousands of years afterward. Physics has a proven pretty detailed understanding of how the first atoms formed out of simpler particles. The temperature cooled down enough for complex matter to be stable, and these atoms were later fused into heavier elements. So let’s think further back to the instant of the Big Bang. The physics laboratories simulate the condition to the tenth of a second after the Big Bang. It found the existence of short-lived unstable particles made of protons and neutrons. Before that point, there was no material. The 2023 Nobel Prize winner simulated the condition almost close to zero time of the Big Bang by analyzing from electron.
A plausible hypothesis is that the physical world was made up of short-lived elementary particles, like quarks, the building blocks of protons and neutrons. There were both matter and “antimatter” in roughly equal quantities. Each type of matter particle, such as the quark, has an antimatter “mirror image” companion, which is nearly identical to itself. Matter and antimatter annihilate in a flash of energy, these particles are constantly created and destroyed. So we can argue the concept of death and life is valid both from science and spiritually.
Our astronomical advancement of seeing stages of the death of a star is a reasonable starting point for the stage of the dying star.
to be continued.
Message
Like Debu I am also an amateur cosmologist. I have no formal education about this subject. i have not done any serious reading but always read any articles I happen to find. Here is my theory about birth and death of this universe.
Science tells us the Universe is still expanding. I presume that is due to the energy from the Big Bang. My theory is eventually that force will lose out to the force of gravity. Things will come to a standstill and then gradually fall back into a giant mass of energy, just like before the Big Bang. As it is we are more than 13.5 billion years. Who knows how long it will expand? Then again initially it will take long time to collapse because everything will be so far apart that the force of gravity also will be very small. Of course at the end everything will collapse rapidly (relatively).
