dark matter

She used galaxies’ rotations to discover the first direct evidence of dark matter in the 1970s while working at the Carnegie Institution in Washington.
While BURST is not the first computer code to simulate conditions during the first few minutes of cosmological evolution, it can achieve better precision by a few orders of magnitude compared to its predecessors.
Though both dark matter and dinosaurs are independently fascinating, you might reasonably assume that this unseen physical substance and this popular biological icon are entirely unrelated. And this might well be the case. But the Universe is by definition a single entity and in principle its components interact.
Most people mistake their own perspective, shaped by their subjective and limited perception, for the absolute reality of the external world. Questioning this assumption is what advanced our research on dark matter. It is also the only thing that has ever advanced human empathy.
We can't see it or feel it. But as Lisa Randall says, dark matter may explain a lot about our universe--including the dinos' demise.
If our Galaxy truly contains many intelligent civilizations, some of which may be ahead of us by a billion years, how is it possible that we have not seen any sign of them yet? Nobody knows the answer to this so-called "Fermi Paradox," but one of the speculations is that there exists some bottleneck to the emergence of intelligent civilizations, and that this bottleneck could have either been in our past, or we will hit upon it in the future.
Three great unsolved mysteries remain, and they are the same riddles asked by ancient Greek philosophers: What is the universe made of? Where did the universe come from? How do we know what's real?
But in the last half century or so, a great many theories either cannot be proven through gathering evidence or barely can be.
Would a small change in even one of the fundamental constants cause the whole edifice to crumble? This question, while fundamental, may also seem completely inaccessible.
Using a very sophisticated camera containing 570 million pixels, scientists imaged distant galaxies, looking for tiny distortions in the galaxies' shapes. This distortion is caused by a phenomenon called gravitational lensing.
As a creative project, Dark Matter is rooted in the pair's early days of becoming politicized together, as well as their
"This tiny (several hundred extra photons) excess has been interpreted as originating from very rare decays of dark matter
Dark matter continues to live up to its name. The most recent results from the European Space Agency's Planck spacecraft appear to cast serious doubt on previous claims of potential detections of the elusive dark matter particles.
Scientists have assigned the role of Mister Answer to science, the source of knowledge on every subject. This is peculiar because science does not accept a complete body of knowledge at any one time as final, therefore no answer can be final. This is how science progresses. Scientists, though, often forget that.
