Between the 2nd millennium BCE and the 2nd century CE, astronomy and astrology continued to develop and evolve. In addition to monitoring the proper motions of the planets and the movement of the constellations through the Zodiac, Greek astronomers also articulated the geocentric model of the Universe, where the Sun, planets and stars revolve around the Earth. Next-generation telescopes like the James Webb Space Telescope (JWST) and ground-based telescopes like the Extremely Large Telescope (ELT) are also expected to allow for additional breakthroughs in our understanding of the Universe in the coming years and decades. In this amount of time, with speed greater than the speed of light, the Universe gradually grew, and it still expands even to this day. There isn’t actually an answer to why the Universe is this big.

Thanks to temperatures dropping to 1 billion kelvin and energy densities dropping to about the equivalent of air, neutrons and protons began to combine to form the Universe’s first deuterium (a stable isotope of hydrogen) and helium atoms. However, most of the Universe’s protons remained uncombined as hydrogen nuclei. He argues that this "implies that any conceivable parallel universe theory can be described at Level IV" and "subsumes all other ensembles, therefore brings closure to the hierarchy of multiverses, and there cannot be, say, a Level V." [29] In 1915, a few months after Einstein had published his Theory of General Relativity, German physicist and astronomer Karl Schwarzschild found a solution to the Einstein field equations that described the gravitational field of a point and spherical mass. This solution, now called the Schwarzschild radius, describes a point where the mass of a sphere is so compressed that the escape velocity from the surface would equal the speed of light.

Retrieved 18 September 2020. It does not follow that the universe is being perceived in full here. We’re may just be seeing ourselves at the heart of a bubble somewhere inside of and made by infinity. Its that we could be ‘the infinitesimals’, looking at ‘the first 1’ rolled out in time, what the word and meaning anchor for me. Cyr-Racine, Francis-Yan; Ge, Fei; Knox, Lloyd (18 May 2022).

Fate of the Universe:

Everything in the Universe is in motion, and it appears that many celestial objects, such as galaxies , are moving away from us. Perhaps, this is the true end of the Universe, when things will be so far apart that nothing could be reached anymore, and nothing could be concluded as being the Universe anymore since everything will be so far apart, we wouldn’t even know its there. Did you Know? There is a debate about whether the other worlds are real in the many-worlds interpretation (MWI) of quantum mechanics. In Quantum Darwinism one does not need to adopt a MWI in which all of the branches are equally real. [93] Modal realism [ edit ]
