29 wrz 2020 · The observable Universe is 93 billion light-years in diameter. Some scientists believe its true size is even scarier than that. By using the Bayesian model averaging, scientists estimated that the Universe is at least 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.
The observable universe is isotropic on scales significantly larger than superclusters, meaning that the statistical properties of the universe are the same in all directions as observed from Earth. The universe is bathed in highly isotropic microwave radiation that corresponds to a thermal equilibrium blackbody spectrum of roughly 2.72548 ...

Let's start by saying the Universe is big. When we look in any direction, the furthest visible regions of the Universe are estimated to be around 46 billion light years away. That's a...
26 wrz 2023 · The best current estimate is that the universe’s diameter is at least 93 billion light-years. And if cosmic inflation is correct (a long story, but a likelihood), then the visible...
4 dni temu · The estimated age of the universe since the big bang is 13.8 billion years, so the light emitted by objects in space that humans can see has been traveling toward Earth for no more than 13.8 billion years.
