The Big Bang Theory
大爆炸理论
The Big Bang theory is a theory scientists use to explain the creation of the universe.
大爆炸理论是科学家用来解释宇宙产生的理论。
The theory states that all of the matter in the universe began to expand from one single point.
该理论指出，宇宙中的所有物质都是从一个点开始膨胀的。
This idea was first proposed by astronomer Georges Lemaitre in 1927.
这个想法最早是由天文学家乔治·勒梅特于1927年提出的。
He received evidence to support his theory when another astronomer named Edwin Hubble observed that galaxies seemed to be moving away from each other.
当另一位名叫埃德温·哈勃的天文学家观察到星系似乎在远离彼此时，他收到了支持他理论的证据。
This was an indication that the universe was expanding.
这是宇宙正在膨胀的迹象。
Because of this new information, Lemaitre concluded that the universe must have once been smaller and denser.
由于这一新信息，勒梅特得出结论：宇宙一定曾经更小、密度更大。
According to the theory, the universe began as something known as a singularity, which is an area where matter is infinitely dense.
根据该理论，宇宙起源于所谓的奇点，奇点是物质无限密集的区域。
Over 13 billion years ago, this singularity began to expand, and the matter inside it formed atoms that would later form stars and planets.
130多亿年前，这个奇点开始膨胀，它内部的物质形成了原子，后来又形成了恒星和行星。
Lemaitre’s idea received a lot of criticism, because most scientists at the time believed that the universe had existed forever.
勒梅特的想法受到了很多批评，因为当时大多数科学家都认为宇宙是永恒存在的。
However, throughout the 20th century, scientists continued to find proof that Lemaitre’s theory was accurate.
然而，在整个20世纪，科学家们继续寻找证据，证明勒梅特的理论是准确的。
Today, the Big Bang theory is the most widely accepted explanation for how the universe was created.
今天，大爆炸理论是关于宇宙如何产生这一问题最为广泛接受的解释。
