In the suit I wear, the mythology, the movie is made of energy, so it's not something I can physically wear, so we were wearing these motion capture suits which we are wear this gray suits with these tracking dots, we look soft of like these crash te
The Color Of The Universe 宇宙的颜色 When we look up into the night sky it seems black, but scientists have observed something different. In this Moment of Science we discuss the color of the universe. 当我们仰望夜空的时候,它看上去
In either case, get ready for a really big bang. 无论哪种情况,准备好来一次真正的大爆炸。 Naturally, you will wish to retire to a safe place to observe the spectacle. 很自然,你希望退避到一个安全的地方来观察这个
Because from trillions of miles away, these small planets get lost in the blinding glare of their stars brightness. The sad truth of the matter is that earth-like planets are near cosmic specks of dust. And therefore detecting them is really quite ha
To make sure Kepler's truely found a planet, scientists are using one of the largest earth-based telescopes for conformation. This telescope will also determine the planet's mass and distance from its star. Scientists are most interested in the small
When massive stars explode, they can produce gamma-ray bursts. The burst, reported in two papers in Nature, is the earliest descriptive event seen so far in our universe. When I received the text message about the gamma-ray burst, it came ultimately
Scientists are likening the new images from a large asteroid to discovery of a new world. Asteroid 21 Lutetia is located between Jupiter and Mars and the European Space Agency's probe Rosetta passed within about 2,000 miles of it, its onboard camera
Are we alone ?And it ties into all the big questions: how do we get here ? where are we going ?Are we a part of a bigger picture? But for the longest time ,the question was taboo to science . Before the Mid-1990s ,it was considered somewhat embarassi
Those planets are all going to be so hot, and you cant develop something as complex as life. Scientists have gone back to the drawing board, looking to find worlds capable of supporting life, small rocky planets like earth. We dont know that life has
Water allows the sand grains to flow to gather and intermingle and form more complex structures. In the same way, water acts like a cocktail mixer, allowing the atoms and molecules to come together, and also may form the building blocks of life. All
It was he who coined the term Big Bang, in a moment of facetiousness, for a radio broadcast in 1952. He pointed out that nothing in our understanding of physics could account for why everything, gathered to a point, would suddenly and dramatically be
The reason we can be reasonably confident that such an event won't happen in our corner of the galaxy, Thorstensen said, is that it takes a particular kind of star to make a supernova in the first place. 索尔斯坦森说,有理由相信,这种事
What is extraordinary from our point of view is how well it turned out for us. If the universe had formed just a tiny bit differentlyif gravity were fractionally stronger or weaker, if the expansion had proceeded just a little more slowly or swiftlyt
I should say that everything is just right so far. In the long term, gravity may turn out to be a little too strong, and one day it may halt the expansion of the universe and bring it collapsing in upon itself, till it crushes itself down into anothe
The analogy that is usually given for explaining the curvature of space is to try to imagine someone from a universe of flat surfaces, who had never seen a sphere, being brought to Earth. No matter how far he roamed across the planet's surface, he wo

Every object that has mass creates a little depression in the fabric of the cosmos. 凡有质量的物体在宇宙的底垫上都能造成一个小小的凹坑。 Thus the universe, as Dennis Overbye has put it, is the ultimate sagging mattress. 因此
Combining Leavitt's cosmic yardstick with Vesto Slipher's handy red shifts, Edwin Hubble now began to measure selected points in space with a fresh eye. In 1923 he showed that a puff of distant gossamer in the Andromeda constellation known as M31 was
