How would you communicate your actions to others without a PowerPoint file? Can you imagine attending a meeting where PowerPoint is banned? As a matter of fact, PowerPoint took power over your…
Whenever you set out to solve a problem, there are a series of steps you have to take in order to arrive at the answer. Assuming your methods are sound and you don’t make any major errors, the answer you get should be correct. It might be a little higher or a little lower that the “true” value, as measurement (and other) uncertainties are real and cannot be eliminated, but the answer you obtain should be independent of the method you use.
For more than a decade, a conundrum has been building in the field of astrophysics: although there are many different ways of measuring the rate at which the Universe is expanding, they fall into two different classes.
A slew of new studies show that the mystery is now deepening even further.
Above, you can see an illustration of a great many measurements — from different methods, experiments and data sets — of the present rate at which the Universe is expanding. On the one side, you can see results of the early signal method, which includes the imprint of the Universe’s expansion in the cosmic microwave background (from both Planck and WMAP), in the cosmic microwave background’s polarization data (an entirely independent data set), and from baryon acoustic oscillations which imprint themselves in the way galaxies cluster on distance scales of a few billion light-years.
On the other side, you can see results from the distance ladder method, which includes a myriad of independent methods using perhaps a dozen different distance indicators in various combinations. As you can clearly see, there’s a severe…
Buying Bitcoin will not make you rich — unless you are already rich. Not only does the math support this claim but also contemporary world events shaping bitcoin’s value. Despite the fanboys, the…
Something is waiting to be conjured every time I start to create something out of paint or words. My wife makes magic with objects, somehow setting the stage for an atmosphere of enchantment, beauty…
