The Bubble Theory arises from the nature of cosmic inflation, which views the universe having expanded exponentially in the first tiny fraction of a second after the Big Bang. In this scenario of the ‘multiverse’ concept, some parts of space-time expanded faster than others. This created ‘bubbles’ of space-time.

What happens when bubble universes collide?
An ancient collision with a bubble universe would have altered the temperature of the cosmic microwave background (left), creating a faint disk in the sky (right) that could potentially be observed.
Can multiverse collide?
However, we can only observe the Universe where we exist within it, and that’s where a hot Big Bang occurred some 13.8 billion years ago. And to no one’s surprise, there’s no evidence of a bubble collision having occurred in the early Universe, as the imprint such an event would have left is nowhere to be seen.
Who found multiverse?
The term multiverse was coined by American philosopher William James in 1895 to refer to the confusing moral meaning of natural phenomena and not to other possible universes.
Is our universe in a bubble?
What lies beyond all we can see? The question may seem unanswerable. Nevertheless, some cosmologists have a response: Our universe is a swelling bubble. Outside it, more bubble universes exist, all immersed in an eternally expanding and energized sea — the multiverse.
Who made the bubble theory?
One of those theories is known informally as the “bubble model,” and it was proposed by Louis Lerman in 1992. The Prebiotic Origin of Organic Molecules, or “Pre-BOOM,” hypothesis proposes that bubbles in the sea were the key to helping create complex organic matter that eventually became life.
What is beyond the universe?
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
What is beyond the multiverse?
The Beyond is an unobservable space outside the Multiverse. It is the remnants of the Second Cosmos and is inhabited by the Beyonders.
Is the universe a true vacuum?
Our universe is not a true vacuum, it is a false vacuum according to Higgs mass. This paper claims that the universe was created out of nothing. But this nothing is really something – “false vacuum”.
Are black holes baby universes?
The theory of baby universes During inflation, baby universes could have branched from our Universe. According to Kavli IPMU researchers, a small daughter universe would eventually collapse, but the large amount of energy released in the small volume causes a black hole to form.
Is the universe eternal?
While the universe is evolving, there is no beginning and no end – the universe exists forever. The early state of inflation is described in two different, but equivalent pictures. In the freeze frame the universe emerges from an almost static state with flat geometry.
What is daughter universe?
Daughter Universes or Many Worlds Theory, proposed by Hugh Everett, is an idea that is based on the theory of quantum mechanics. Everett proposed that the universe creates a copy of itself for every possible outcome of a situation to occur.
Do parallel universes exist?
There are far more particles in the universe than 1,000, so the chances for another Earth are not in our favour. Unfortunately, we don’t know if these parallel universes exist. Or at least, we don’t at the moment. Physicists are trying to find ways to test these theories, but it is very difficult.
How many universes exist?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Do we live in multiverse?
We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.
What are Quantum bubbles?
Quantum foam (also known as spacetime foam or spacetime bubble) is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics. Matter and antimatter are constantly created and destroyed. These subatomic objects are called virtual particles. The idea was devised by John Wheeler in 1955.
Is the universe a balloon?
The balloon is the universe, and as more air is blown into it, you would see the space or surface area of the universe expanding and every point on its surface getting further and further away from one other.
Should I worry about vacuum decay?
How worried should we be about vacuum decay? If the Higgs field is metastable, and it yet may not be, then it is predicted that a vacuum decay event would occur within the next 20 to 30 billion years, so it’s probably not an imminent threat.
What causes a bubble?
Typically, a bubble is created by a surge in asset prices that is driven by exuberant market behavior. During a bubble, assets typically trade at a price, or within a price range, that greatly exceeds the asset’s intrinsic value (the price does not align with the fundamentals of the asset).
Can bubbles be rational?
Simply stated, a rational bubble is present whenever an asset price deviates progressively more quickly from the path dictated by its economic fundamentals. The growth of rational bubbles reflects the presence of arbitrary and self-confirming expectations about future increases in an asset’s price.
What does human bubble mean?
Is space infinite or finite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
How cold is space?
The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops.
What was there before the universe?
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that’s what we’ve been told by physicists for the past several decades.
How long will universe last?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if the Higgs field is metastable.
