The observable universe is a ball-shaped region of the universe we live in comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time. In visible light, the farthest we can see comes from the cosmic microwave background, a time 13.8 billion years ago when the universe was opaque like thick fog. Some neutrinos and gravitational waves that surround us cme from even farther out, but humanity does not yet have the technology to detect them.
According to calculations, the radius of the visible universe, represented by the cosmic microwave background radiation (CMBR), is approximately 14.0 billion parsecs (or 45.7 billion light-years) in size, while the comoving distance to the edge of the observable universe is approximately 14.3 billion parsecs (or 45.7 billion light-years), taking into account the expansion of the universe since light was first emitted (about 46.6 billion light-years). THIS IS OUR REAL WORLD. Which contains all known fictions. Anything bigger is a higher existence.
Multiverses[]
Our universe is contained in a multiverse along with other multiple (and probably alternate) universes - perhaps an immeasurable number - which may or may not contain humans or life at all. In fact, some of them may be so hostile, and chemistry or physics as we know them, may not function properly. The possible total number of universes in our multiverse, based on the probability law, reach as high as 10^10^10^122 megaparsecs, as implied by a suggested resolution of the No-Boundary Proposal.
Our universe was involved in a collision 13,786,620,000 ± 21,000 years ago. In the southern southeast universe, in an oval stretching across 1,800,000,000 light-years, there is a spot slightly colder than the regular universe, that is devoid of what should be an area of about 10,000 galaxies. It is only 0.00015°C colder than the rest of the universe, but that is much colder on a scale of space temperature. Why does this spot exist? It is due to this universal collision! All the galaxies were sucked up from that area into the other universe, and the area gradually grew colder over time. The laws of physics were somewhat changed, and into what they are today. The collision would look like an extremely cold mirror coming towards you, and then that mirror suddenly catching on fire and burning. Everything in the area would be sucked into the other universe, and everything in the other universe’s area of collision would be sent into ours. The universe could have been much colder or older than ours, causing the area to be frozen. Thermodynamic equilibrium would most likely have started making the area warmer, turning it into what it is today.
Other Information[]
Most universes, including ours, shall eventually "die" as the second law of thermodynamics ensures that energy becomes less and less usable over time. This universe is also the least confusing to understand, as it is the only one that we know exists so far.
