The Roblox Universe, also known as Robloxverse or The Robloxxy Universe, is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The theory that spaces and time emerged together is the prevailing cosmological description of the development of the Roblox Universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago, and the Roblox Universe has been expanding ever since the emergence of space and time. While the spatial size of the robloxian universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
The Roblox Universe has over six trillion galaxies; a billion black holes are in it. The universes that are connected to Roblox Universe could be the Minecrafter Universe and the Fortnite Universe. It is known that matter in the Roblox Universe is unable to transported to other universes as the universe's foundations of matter, energy, and spacetime would destroy the matter.
It is also known that the Roblox Universe is spherical; the sum of the angles of a triangle exceeds π radians and there are no parallel lines; all lines eventually meet. The geometry of the Roblox Universe is, at least on a very large scale, elliptic. It has been calculated that gravity will become so powerful that the expansion of the universe would grind to a halt 600 trillion years from now, during which it would start to contract until all matter in the Roblox Universe collapses to a point, a final singularity termed the "Big Crunch", the opposite of the Big Bang.
It is also known that the Roblox Universe has not enough dark energy to create a repulsive force that would be sufficient to cause the expansion of the universe to continue forever.
Fun facts
Robloxians know how many stars are present within Robloxxy Way (about 400 billion) and how many galaxies are present throughout the visible Roblox Universe (about 6 trillion).
One of these "bubbles," where inflation ended, gave birth to the Roblox Universe some 13.787±0.020 billion years ago, where our entire visible Universe is just a tiny portion of that bubble's volume.
Most astronomers think that the Roblox Universe was formed during the emergence of space and time which occurred 13.787±0.020 billion years ago.
