The Big Bang Never Happened?

Modified on by Max Wilbert



Rumors of the Big Bang's Demise are Greatly Exaggerated

In early 2015, a new idea began circulating in popular science media: that the Big Bang never happened. Is this true? No. The evidence for the Big Bang theory is still very strong. A new concept has simply emerged and changed our understanding of the Big Bang, leading to some interesting discussion.

The idea that the Big Bang never happened actually has its origins in good science. A paper called “Cosmology from quantum potential” was published in the February issue of Physics Letter B by Ahmed Farag Ali and Saurya Das. Ali and Das propose a new mathematical solution to one of the fundamental issues in physics.

So Was There a Big Bang After All?

The Singularity Problem

Basically, in the classical Big Bang model, if you go back far enough in time (around 13.8 billion years), the universe existed as a singularity: an infinitely small, infinitely dense point of matter smaller than any subatomic particle.

This concept of singularities causes issues with physics, because it crosses two realms that usually don’t mix: quantum mechanics (which describes the behavior of tiny low-mass particles) and special relativity (which describes the behavior of large and more massive objects, up to the size of the biggest stars and galaxies).

With a singularity, you have some of both: a miniscule object with extremely high mass. This makes the math go haywire. Neither quantum mechanics nor relativity can fully describe what happens in a singularity.

Eliminating the Singularity

Ali and Das, in their recent paper, attempt to solve some of these issues by eliminating the initial singularity predicted by the classical Big Bang theory. Instead, they predict that the universe existed as a “quantum potential” before collapsing into the Big Bang. It’s similar to the classical Big Bang theory, but without the singularity bit.

It’s a subtly different approach, and scientists are calling it more of a “proof of concept“—a simplified model that proposes a different solution to these fundamental problems—than a new, firmly-established theory.

Ali and Das aren’t truly proposing that the Big Bang never happened. Instead, that idea comes from overzealous popular science writers making grandiose claims to boost readership. The scientific evidence that there was a Big Bang is still darn strong at this point (for example, cosmic microwave background radiation).

Of course, this is all a simplification of the discussion that’s going on. To really understand all the details, we’d have to brush up on our quantum theory, advanced mathematics, and theoretical physics! A good place to start is with Brainscape’s Physics 101 deck.

I guess time actually stops and you have an explotion in light speed. Time starts again when the univers is less compressed.

John Kenneth Mannes 2 years ago

Maybe I misunderstood, but your saying (link) that the whole universe could not appear in a singularity point, because there would be too much mass?

This "other dimensjon" can effect our universe/dimensjon iguess, as it can suddenly move small things around.

John Kenneth Mannes 2 years ago

Or maybe when something moves faster than light speed it goes into another dimension, time stops and it comes back in a different place when the speed is reduced. This other dimension would be only for small things that does not effect our dimension (dimensjon or a place with different laws of physics) and it lays on top of our dimensjon. In this way Einstein theory will not be broken in our dimensjon. This duplication thing I mention earlier does not make sense for me now, but I have a feeling that maybe Einsteins law does not only describe our universe (dimensjon), but it also created our dimensjon as it describes the energy level (max speed of light) everything is supposed to be in. However I think that the speed of time before the big bang influenced the big bang it self. I also think that maybe In some strange way that time is supposed to move in a certain speed depending on what is around it in space. The question is what would happen if there should be some kind of unbalance between space and time? Maybe something "dormet" awoke, and changed the balance between space and time?

John Kenneth Mannes 2 years ago

So einsteins law works when what is in our dimention, stays in our dimention.

John Kenneth Mannes 2 years ago

Time going so fast i mean

John Kenneth Mannes 2 years ago

It should be less in the universe for it to move so fast.

John Kenneth Mannes 2 years ago

So, the final equation would be something like T=E
E=MC2 like Einstein
T=speed of time or this duplication process going in the speed of light untill the universe is so compact that time stands still. I got this feeling that our universe works in frames like the movies, because how can something move without moving, I guess between the frames. Our univers works on a freqancy. Can something be on two frequancys at the same time? What? So maybe when the universe notice that time is moving faster then how much should be in it, in the frequancy of light it moves in two dimentions (this and a faster one for movement) so it can travel faster then light (C), the result is duplicatin in our universe untill time stops. Sorry for my bad english, Im still tryying to figure out all this in my head.

John Kenneth Mannes 2 years ago

Because I have heard that when something is travelling in the speed of light, time stands still.

John Kenneth Mannes 2 years ago

Ohh, yeah the size off our universe is actually decided by the speed of time before the big bang, as you have duplication on a quantum level untill time almost stops. If time stops nothing would happen.

You should know what Vedas say about the theory of creation. You can find the details at https://theoryofsouls.wordp... This theory can be found in Bible also.

(1) Universe has Brahma day and Brahma night, each about 8.6 billion years long. In Brahma night everything remains dark. Universe begins to take birth at the beginning of the day, matures, and then dies at the end of the day. It remains dead for the entire night.

(2) All objects of the universe are created by their individual souls. That is you are created by your soul and I am created by my soul. So there is no God in Vedas. All souls have consciousness, intelligence, mind, and other sensors.

(3) All objects of the universe are continuously and simultaneously interactive with each other for all past, present, and future times. This simultaneity law defines our global destiny, from which individual destiny can be created. Thus all souls are continuously talking to each other, whether you want it or not.

(4) Destiny is already defined. It is not dynamically created. Thus events do not happen, they are already there, we just pass through them.

Everything is periodic in our universe, because all objects, humans, plants, stars, galaxies etc. go through the birth-maturity-death process. Thus it is natural that there will be a largest period of the universe which is the combined period of all events. In the same way, since we reincarnate, there is a gap between two births, which creates the largest gap of Brahma night. The universe is thus eternally recurrent as described by the German philosopher Nietzsche.

actualy thaught (thinking) concept of big bang is birth of galaxy in space, like plus and minus numbers has no end in counting so as atoms and stars are also infinite on numbering proof. so also hierarchy is also infinite. our heart belongs to earth, our liver to moon, our brain to sun and eyes to galaxy, there is no any uper organ having center which may be work equals to big bang, yes but their are hairs which have no center so we can say these are symbol of infinity because these are fifth and sixth sense, an other proof that flow water in pipeline and put light torch along with it, now block both on starting point you will notice both are stoping at the end at same time

Ohh, yeah, maybe there is some universe where "the speed off light" is diffrent? Maybe there are stuff out there that can not effect our universe and does not follow what we know off physics?

John Kenneth Mannes 2 years ago

Soo, im thinking that you can not look at something (the same thing) in two places at the same time, because you can not travel faster then the speed off light, and if you are going to notice any difference from a place where time is going quick or time is going slow, you would haveto travel faster then the speed of light, unless you change the speed of time in one spot by converting something that does not effect time (something like dourmant energy) into something that does effect time (like evrything that would follow Einsteins law "not faster then speed off light") , because then on a quantom level you would travel faster then the speed of light. This would result in the speed off light behaving more like the reaction time off the universe. Evry time the universe fails to react fast enough to the change (speed of light is not fast enough), it will duplicate stuff on a quantom level, and you have the big bang. Maybe string theory is about the frequancy our universe fails to react fast enough, and other dimentions are things that does not effect our universe in its present state?

I am intrigued by Einsteins theory about relativity. He says that nothing can appear or disappear, but also he says that time goes faster where the universe is less compressed. Im not sure if he said that part about time goes faster where the universe is less compressed, but it does not speak against his theories.

John Kenneth Mannes 2 years ago

Its hard to guess about what you can not see. Ohh well

John Kenneth Mannes 2 years ago

so if Einstein was correct (which he probable was), and something can not appear or disappear from the universe, I suppose maybe the relativity created the universe?

John Kenneth Mannes 2 years ago

assuming there was nothing and suddenly the big bang

John Kenneth Mannes 2 years ago

Soo, like if two different time perspectives (speeds) collied, which might happen in the big bang, what then?

John Kenneth Mannes 2 years ago

I am not a physicist, but I have a theory...
I am intrigued by Einsteins theory about relativity. He says that nothing can appear or disappear, but also he says that time goes faster where the universe is less compressed. If you imagine somewhere far away from our universe, a place where time is moving very fast, and then imagine that it is possible to look at where you are now and this far away place at the same time, you also imagine a very small thing in both places (the same thing), then if you look at the thing where it is, it would be one thing, but if you look at both places at the same time there would be two things in the far away place and one thing here.
So, I am thinking that time was moving very fast before the big bang and God farted out something very small that started a chain reaction, because a small thing is big compared to nothing. Time slowed down and the big bang happened. The strange part about this is, if you look at this small thing after the big bang (which is not possible). It would be the whole univers (the big bang). Does this make any sense for anybody out there?

pen up google sky click on Spitzer Infrared Showcase see every galaxy has its own root, (every travels in two sides) as our one is up and west. so every galaxy is traveling on its diffrent root, some are going away some are coming near, proof is that see longitude and aptitude of each galaxy and find such location on google maps you will find that two galaxies looked from one earth location are traveling opositely, it is proofing that not all galaxies are traveling in one direction, an other thing is that if all universe is expending and most galaxies are traveling one side then why galaxies are collapsing each other, so big bang not happend

For the record, I did not understand the complicated math equations in the link.
