The Big Bang Theory is the leading explanation of the slotxo เวอร์ชั่นล่าสุด beginning of the universe. Simplestly, it says that the universe, as we know it, began with a small universe and then swelled over the next 13.8 billion years to the universe as we know it today.Since today's instruments do not allow astronomers to look back at the birth of the universe, much of what we understand about the Big Bang theory comes from mathematical formulas and models. However, astronomers can see The "resonance" of expansion through a phenomenon known as the cosmic microwave background.While most of the astronomy community accepts theories But there are also some theorists who have explanations other than the Big Bang, such as eternal inflation or a shaking universe.The phrase "The Big Bang Theory" has been popular with astrophysicists for decades. But it became very popular in 2007 when the comedy show of the same name was released on CBS. Home-based performances and the educational lives of many researchers. (Including astrophysicists) and ending in 2019


The first seconds and the birth of light

In the first seconds after the universe started, its ambient temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius), according to NASA data.The universe contains many fundamental particles, such as neutrons, electrons, and protons. These disintegrate or combine as the universe cools.This early soup was probably impossible to look at because the light couldn't shine inside. "Free electrons cause light (photons) to scatter the way sunlight falls from water droplets in the cloud," NASA said. However, over time, free electrons meet the nucleus and form neutral atoms. This light was allowed to shine through approximately 380,000 years after the Big Bang.Sometimes referred to as the Big Bang's "halo",

this light is better known as the Cosmic Microwave Background (CMB), first predicted by Ralph Alpher and other scientists in 2009. In 1948, it was discovered almost 20 years later.Arno Penzias and Robert Wilson, both of Bell Telephone Laboratories in Murray Hill, New Jersey, are building radio receivers in 2009. Fri 1965 and received a higher temperature than expected. At first they thought the anomaly was caused by pigeons and their droppings. But even then, they cleaned up and killed the pigeons trying to perch their antennae. But the anomaly remains.Meanwhile, the Princeton University team (led by Robert Dicke) sought to find evidence of the CMB and realized Penzias and Wilson stumbled together. Both groups published papers in each group. Astrophysical Journal in 1965


Age of the universe

The cosmic microwave background has been observed in a number of missions. One of the most famous space exploration missions is NASA's Cosmic Background Explorer (COBE) satellite, which mapped the sky in the 1990s.Several other missions followed in the footsteps of COBE, such as the BOOMERanG Experiment (Millimetric Extragalactic Radiation and Geophysical Balloon Observation), the European Space Agency's Wilkinson Microwave Anisotropy Probe (WMAP) and the European Space Agency's Planck satellite.Planck's observations, first published in 2013, map the background in unprecedented detail and reveal that the universe is older than previously thought: 13.82 billion years, or more than 13.7 billion. Year The Observatory Research Mission is underway and new maps of the CMB are published periodically.The map, however, gave rise to new mysteries, such as why the Southern Hemisphere is slightly redder (warmer) than the Northern Hemisphere. The Big Bang Theory says most CMBs are the same no matter where you look.The CMB investigation also helps astronomers know the composition of the universe. Researchers think that the universe is largely composed of matter and energy that cannot be "perceived" with our conventional tools, leading to the names "dark matter" and "dark energy". Matter such as planets, stars and galaxies


The faint signal of cosmic inflation

While astronomers can see the beginning of the universe But they also find proof of the rapid inflation using gravitational waves, the slightest perturbation in space-time rippled by massive disturbances such as two colliding black holes or the birth of the universe.The theory states that in the first seconds after the universe is born, our cosmos flies faster than the speed of light. (This does not violate Albert Einstein's speed limit. He once said that the speed of light is the fastest that can be traveled within the universe - but that statement does not apply to Expansion of the universe)
