By using Bayesian model averaging, which focuses on how likely a model is to be correct given the data, rather than asking how well the model itself fits the data. They found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across.

Because each galaxy has a center the Universe would also have a center as well. Astronomy isn't able to pinpoint the center of the Universe because, well 3.5 trillion light years is a really big distance to have to peer through all of the objects creating light that would obscure even the most powerful telescopes ability to accurately detail the observable night sky at such a distance.
But we can see apply relative associations between the Universe and life.
First lets look at minerals. Minerals will never consume energy and then expand and reproduce. Water will never consume energy and then expand and reproduce. All of the elements on the Periodic Table of elements are inanimate, meaning that they do not have their own thought processes but merely interact and react with each other based on chemical attributes that combines the atoms into molecular strands. Granted a mineral contains millions of molecular combination strands but regardless of how big the mineral composition builds up it will never actively consume energy and reproduce.
Every aspect of life, however small or great, consumes energy and rearranges the various atoms from the Periodic Table of Elements for its own need which has created the diversity of life.
The key factor that is present between life in general and the Big Bang is that life consumes energy, then expands and reproduces.
The Big Bang also had to have consumed energy then expanded and produced life as well. The Universe is thought to be constantly expanding much like the stomach of a pregnant woman expands during her pregnancy. As the fetus inside intake more energy through its mother it grows or expands and is then born in a tumult of excitement for the both the doctors, the parents and the infant itself.
After the Big Bang the tumultuous excitement of quarks raced outwards combining together to form the basis of atoms that then formed the basis of the Universe and the celestial objects within the Universe.
The chemical compounds that then existed like I said above have no reason to want to consume energy or expand into something larger. They are merely energy that combines to create other forms of energy. Energy reacts to other forms of energy based on its composition. Take for instance a lightning bolt striking a rock. A random act of energy transferring between the lightning bolt and the energy of the rock. There was never any direct manipulation of the energy between the two states of energy directing their interaction.
But for life to exist energy needs to be directed precisely and exacting or life doesn't exist.
Like I stated before in order for both life and the Big Bang to have existed, the elements that created the Big Bang had to be directed precisely and exacting in order to create the elements of the Periodic Table of Elements that life is comprised of and needs to exist. If the Big Bang is merely like the lightning strike and the rock, a transfer of energy between two states, then neither the lightning strike nor the rock would exist because they are energy. Energy does not have a need to do anything.
Life on the other hand has the need to transfer energy between two states in order for life to exist. Without life needing energy to transfer between two different states there is no existence of to the Universe.
Another interesting relative association is that in order for life of all forms to be life it must consume energy and expand and then produce. Such a blue print or a model could only have existed before the Big Bang in some Quantum storage device of the Universe. Every single aspect of life in the Universe begins at least 100,000 times smaller than its eventual size. Humans start out as microscopic cells that consume energy and then grow and expand into a full grown human being. Lions and tigers and bears.....dolphins, ants, trees, flowers and even the virus all come from cells that small. The Big Bang also came from a smaller cell as well that then expanded into a 7 trillion light-years across entity.
Science has stated that life came after the Big Bang. But how would life know how to consume energy, expand and reproduce if it came after the initial event that created life? If you follow the belief that life came after the Big Bang then the Universe is the womb of the mother that we are consuming energy and expanding in.
But just like the fetus in the mother's womb is to life in the womb of the Universe where is the umbilical cord or the transfer of the set of directions from the Big Bang traveling through the Universe to instruct DNA and RNA to use the elements of the Periodic Table to build life? There would have to be a connection to the Big Bang and life on Earth much the same as there is a connection between the mother and developing fetus.
If we roll back the connection above to the point at which the Big Bang took place there has to be an umbilical cord between the Big Bang and the Mother of our Universe in order for the transfer of instructions that directed the energy of the Big Bang to expand outwards in such a manner that allowed humans and other life to exist in the Universe.
The premise above folds over on itself into the infinite paradox but would confirm at least that in order for life to have existed a specific set of instructions would have been necessary to create the Big Bang.
Therefore life created the Universe in order to consume energy, expand and reproduce. Only life would have the ability or need to accurately direct specific sets of instructions to create an energy transfer between two states. Such a specific set of instructions would include the Big Bang.
Two rocks however will never transfer energy between their two states nor do they have a need to do so.
