These are the first moments ofthe universe. We know that it went from an incredibly small, hot, dense pointthat grew and spread out super fast. How fast did it just after the Big Bang,all of the universe would have fit inside a soccer ball that size small. Icould tell in less than...
(Link to David Jarvis' gallery.) Dense, heavy masses like the Sun cause very large amounts of curvature in very small spaces, significant enough tobend starlightby amounts significant enough you could notice it with1919's technology. But that'slocalcurvature, the same way mountains, valleys ...
A blue white star is very dense( 密集的)and hot. When a star becomes red, its energy has begun to fade(消失). Therefore, a star that is nearing the end of its life is called a red giant(红巨星). While humans grow smaller in old age, stars grow bigger until they die. In the ...

A star's color has a lot to do with its temperature. A blue-wbite star is very dense(密集的) and hot. When a star becomes red, its energy has begun to fade(消失). Therefore, a star that is nearing the end of its life is ...
“Ah, ah, ah” ecstatic moaning. Of course, these topics are worthy of thousands of pages of ‘unpacking’ from my dense and succinct overview. And, such an encyclopedic and detailed treatment would make thescientia sexualislook dramatically more ‘austere’ and more of a handicapping of a ...
1、观察宇宙首先用到的是光,可见光First there was light,visible light.然后我们用无线电和X射线观察宇宙Then, we viewed the universein radio waves and X-rays.自从天文学诞生以来Ever sincethere's been astronomy,我们一直在观测不同种类的光we've been looking atdifferent kinds of light并利用更长的曝光...
Well, this scientist has scheduled the end of the universe. Here's when and how it all goes down.
with the discovery of a faint background of microwaves throughout space. The only reasonable interpretation is that this “cosmic microwave background” is radiation left over from an early hot and dense state. As the universe expanded, the radiation cooled until it became just the remnant we ...
