His ideas would be further refined by 16th/17th century mathematicians, astronomer and inventor Galileo Galilei. Using a telescope of his own creation, Galileo would make recorded observations of the Moon, the Sun, and Jupiter which demonstrated flaws in the geocentric model of the Universe while also showcasing the internal consistency of the Copernican model.

It turns out that atoms only make up 4.6 percent of the universe. Of the remainder, 23 percent is made up of dark matter, which is likely composed of one or more species of subatomic particles that interact very weakly with ordinary matter, and 72 percent is made of dark energy, which apparently is driving the accelerating expansion of the universe.

A few minutes into the expansion, the period known as Big Bang nucleosynthesis also began. Siegfried, Tom (17 September 2019).

"In some worlds there is no sun and moon, in others they are larger than in our world, and in others more numerous. The intervals between the worlds are unequal; in some parts there are more worlds, in others fewer; some are increasing, some at their height, some decreasing; in some parts they are arising, in others falling. They are destroyed by collision one with another. There are some worlds devoid of living creatures or plants or any moisture." ... Only an infinite number of atoms could have created the complexity of the known world by their random motions... In this sense, the atomist-multiverse theory of antiquity presents a striking parallel to the situation in science today. The Greek atomists' theory of the ultimate nature of matter on the smallest scales implied the existence of multiple universes on cosmic scales. Modern science's most popular attempt to describe the fundamental nature of matter—superstring theory—also turns out (much to the theorists' surprise) to imply a vast multiplicity of vacuum states, essentially the same thing as predicting the existence of a multiverse. Think of it this way, we might see the Universe as being big now, but in the far future, who knows how future generations would view it. Our ancestors didn’t have cars or planes, and they would traverse the world in many months, even years. For them, traveling from point a to b seemed incredibly difficult, and they themselves might have thought, why is the Earth so big? The first to whom we can definitively attribute the concept of innumerable worlds are the Ancient Greek Atomists, beginning with Leucippus and Democritus in the 5th century BCE, followed by Epicurus (341–270 BCE) and Lucretius (1st century BCE). [7] [8] [6] [9] [10] [11] In the third century BCE, the philosopher Chrysippus suggested that the world eternally expired and regenerated, effectively suggesting the existence of multiple universes across time. [10] The concept of multiple universes became more defined in the Middle Ages. [ citation needed]
The term was first used in fiction in September 1961 in the DC comic book titled Flash of Two Worlds (Flash Volume 1 #123) by Carmine Infantino and Gardner Fox. In the story, Flash meets with his duplicate version of another Earth (Earth-2) and another Flash (Flash-2). [ original research?] Steinhardt, Paul (9 March 2014).

The concept of other universes has been proposed to explain how our own universe appears to be fine-tuned for conscious life as we experience it. In terms of its shape, spacetime may exist in one of three possible configurations – positively-curved, negatively-curved and flat. These possibilities are based on the existence of at least four dimensions of space-time (an x-coordinate, a y-coordinate, a z-coordinate, and time), and depend upon the nature of cosmic expansion and whether or not the Universe is finite or infinite.In his 1930 autobiography My Early Life, Winston Churchill cited the theory when explaining his preference for "believing whatever I want to believe": [ original research?] Today, this term is often to used to refer to all things that exist within the known Universe – the Solar System, the Milky Way, and all known galaxies and superstructures. In the context of modern science, astronomy and astrophysics, it also refers to all spacetime, all forms of energy (i.e. electromagnetic radiation and matter) and the physical laws that bind them. Origin of the Universe: The globular cluster NGC 6397 contains around 400,000 stars and is located about 7,200 light years away in the southern constellation Ara. With an estimated age of 13.5 billion years, it is likely among the first objects of the Galaxy to form after the Big Bang. (Image credit: NASA/Francesco Ferraro/Bologna Observatory) Many physicists who talk about the multiverse, especially advocates of the string landscape, do not care much about parallel universes per se. For them, objections to the multiverse as a concept are unimportant. Their theories live or die based on internal consistency and, one hopes, eventual laboratory testing.
The universe is currently estimated at roughly 13.8 billion years old, give or take 130 million years. In comparison, the solar system is only about 4.6 billion years old. The Sun is one astronomical unit (AU) away from us. One astronomical unit is 149,598,000 km / 92,955,887 miles, and in our top shape, we could reach it in 25 days. Now, the Universe is 93 billion light-years across, and one, just one light-year, is equivalent to 63,000 astronomical units.

For example, scientists believe that about 10 -11 seconds after the Big Bang, particle energies dropped considerably. At about 10 -6 seconds, quarks and gluons combined to form baryons such as protons and neutrons, and a small excess of quarks over antiquarks led to a small excess of baryons over antibaryons. What is the Universe? That is one immensely loaded question! No matter what angle one took to answer that question, one could spend years answering that question and still barely scratch the surface. In terms of time and space, it is unfathomably large (and possibly even infinite) and incredibly old by human standards. Describing it in detail is therefore a monumental task. But we here at Universe Today are determined to try! For each day and the week ahead. The texts are the ones used in the UK: the Jerusalem Bible and the Grail psalms.

Philosopher Philip Goff argues that the inference of a multiverse to explain the apparent fine-tuning of the universe is an example of Inverse Gambler's Fallacy. [59] This began at 10 -37 seconds, where the phase transition that caused for the separation of forces also led to a period where the Universe grew exponentially. It was also at this point in time that baryogenesis occurred, which refers to a hypothetical event where temperatures were so high that the random motions of particles occurred at relativistic speeds. The vector sum of the external forces ( F) on an object is equal to the mass ( m) of that object multiplied by the acceleration vector ( a) of the object. In mathematical form, this is expressed as: F= ma In the 1920s, astronomer Edwin Hubble discovered the universe was not static. Rather, it was expanding; a find that revealed the universe was apparently born in a Big Bang. If the density of the universe exactly equals the critical density, then the geometry of the universe is "flat" with zero curvature like a sheet of paper, according to NASA. If so, the universe has no bounds and will expand forever, but the rate of expansion will gradually approach zeroafter an infinite amount of time. Recent measurements suggest that the universe is flat with only a 0.4 percent margin of error, according to NASA.
