DCosmologists(宇宙学家) can't agree on how fast the universeis expanding because the two methods they use to find out givedifferent results. Now a third method involving gravitational wavescould help break the deadlock.Gravitational waves are the waves in space-time whoseexistence was confirmed ...
Instead, the finding told scientists that the universe is expanding and that there is a direct relationship between how far apart two objects are and how fast they are receding from one another. The Hubble constant has a value that incorporates this speed-distance connection. The problem is ...
甚至时空也会结束 Even space and time will come to an end. 宇宙从它诞生起一直在膨胀 The universe has been expanding since its birth, 渐渐地耗尽使恒星发光的燃料 gradually burning through the fuel that lights its stars. 当燃料耗尽会发生什么? But what happens when the fuel runs out? 宇宙会...

Space may be unimaginably vast, but you can experience and measure it for yourself. You can even measure the universe expanding. Here's are some tips on how to get there. Tip 1: look up, and imagine Look at the night sky. There are stars aplenty, but much of the sky is dark and...
The reader must remain a tantalized spectator rather than an involved participant, since the appropriate language for describing the details in much of science is mathematics, whether the subject is expanding universe, subatomic particles, or chromosomes. Though the broad outline of a scientific ...
So, the idea is that if the universe is currently expanding — which we observe, we see galaxies moving apart from each other — then it stands to reason that in the past, the universe was more compressed. So everything was closer together. And you can kind of dial that extension back...
