There’s new research being touted in the press about a possible solution to the dark energy mystery. The results, published in the peer-reviewed journal PLOS ONE argues that a radical modification of relativity can account for dark energy. The work is so abysmally awful that it makes you wonder just how such a paper got accepted for publication.
I’ve been thinking of ideas for a podcast, and one idea I have is a give and take between myself and other experts outside my field. So here is a first try at that format. It is an exchange with Grant Gutheil, who is a developmental psychology professor. This is just a raw recording to try the format, so it is …
One of the interesting aspects of science is the fact that what we observe is often not what we measure. The data gathered from a particular experiment is just one aspect of scientific study. To really make progress you need to put that data within the context of scientific models. As a result, most of what we study in astronomy and other sciences is deeply dependent upon the models we use to understand the universe.
Everything you experience is experienced from your personal perspective. That seems like a rather obvious statement, but it also applies to humanity as a whole. Everything we experience in the universe is from our point of view. Cosmologically that view is a very narrow window. Humanity has only been around for a moment of cosmic time. We see the heavens …
The European Space Agency has released a short film titled “Ambition.” A mix of science fiction and science, it is visually stunning and captures much of the awe and wonder of space exploration. It’s also part of a growing intersection of science and visual storytelling.
If you ever happen to meet someone who does this kind of orbital logistics, shake their hand and say thanks. Without their work our spacecraft wouldn’t arrive at their destination, and we wouldn’t have the opportunity to do some awesome science.
There is no real evidence to support the idea that a natural fission reactor occurred on Mars. None.
If you have a smartphone, you are carrying around a supercomputing sensor array. Modern phones don’t just make calls, they are also constantly aware of their environment. They know where they are using GPS and mobile telemetry. They know their orientation and motion using gyroscopes and accelerometers. Many measure barometric pressure. They can record images and sound, and can communicate with the global internet. And there are about 1.5 billion of them.
Often in astronomy and astrophysics we talk about the big breakthroughs. Galileo’s discovery of the moons of Jupiter that showed not everything moves about the Sun, Henrietta Leavitt’s discovery of the cepheid luminosity relation which allowed us to measure the distance to galaxies, Eddington’s observation of light deflection that verified Einstein’s theory of general relativity. But much of the field is based upon lesser findings.
