The nature of the 'dark energy' that is I causing the apparent accelerated I expansion of the Universe is, without doubt, the biggest mystery in physics and astronomy. Although it was astrophysical observations
Dark energy is one of the great mysteries of the universe. For decades, scientists have theorized about our expanding universe. Now, for the first time ever, we have tools powerful enough to put these theories to the test and really investigate the big question: “what is dark energy?” NA...
D. A force that makes the universe contract. 相关知识点: 试题来源: 解析 C。解析:文中提到“Dark energy, on the other hand, is even more mysterious. It is a force that is causing the expansion of the universe to accelerate.”,即暗能量是一种导致宇宙加速膨胀的力。反馈 收藏 ...
The total content of the universe without dark energy is only around 30% of what is needed for a flat universe, which is the type of geometry the universe should have if created by the Big Bang. This is because early inflation should have "smoothed out" the universe geometrically like a ...
Shedding light on dark energy has been a bit of a challenge for today's astronomers. What dark energy actually is goes beyond our present scientific understanding. We know with some certainty that dark energy exists; we know how much of the universe is made up of it; we know the influence...

Dark energy and dark matter account for most of the universe, but what are these elusive phenomena? NASA/JPL/Hubble NASA's Wilkinson Microwave Anisotropy Probe (WMAP) provided a true watershed moment in humanity's quest to understand the cosmos when it calculated the age of the universe ...
This discovery posed a new question that scientists continue to explore today: what is the “dark energy” that is overcoming the effect of gravity and pulling our universe apart? Dark energy may be an inherent feature of the universe, or it could be something related to new and unknown part...
Scientists Discover Galaxy That Is 99% Dark Matter Leane points out that the internet was created in part because particle physicists at CERN wanted to find new ways to share data with each other. GPS, meanwhile, relies in some measure on Einstein’s theory of general relativity, which explain...
Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. The Dark Energy Spectroscopic Instrument uses a telescope to create a three-dimensional map of the universe over 11 billion years....
