在天文学领域中,至今仍有很多经典问题困扰着天文学家,这些问题中的有些问题也许会在某一天被解开,有些问题或许永远都是一个谜。暗能量是什么19世纪20年代,天文学家埃德温·哈勃发现宇宙是在膨胀的。1998年,哈勃望远镜发现宇宙正在加速膨胀。这引起了科学家们对暗能量的讨论。暗能量被认为是一种神秘的力量,它让宇宙以不断增长的速度膨胀。暗能量被认为大约占宇宙的73%,但这种东西难以捉摸,还有待检测。
In the field of astronomy, there are still many classic problems plaguing astronomers. Some of these problems may be solved someday, and some of the problems may always be a mystery. What is dark energy In the 1820s, astronomer Edwin Hubble discovered that the universe is expanding. In 1998, the Hubble Space Telescope discovered that the universe is accelerating expansion. This has caused scientists to discuss dark energy. Dark energy is considered a mysterious force that expands the universe at an ever-increasing rate. Dark energy is thought to account for about 73% of the universe, but such things are elusive and yet to be tested.
