And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]

It might seem puzzling, in a Universe bound by the speed of light, that this could be true. Here’s the science behind it. If you look out into the distant Universe, […]
The ICARUS Initiative aims to track migratory animals from space using special transmitters and antennae. The data retrieved from the project will help us conserve biodiversity but has the potential to promote human well-being and prosperity, too.
Is gravitational repulsion a real thing? “For the first time, astronomers have outlined and named the network of galaxies that includes the Milky Way, adding a line to our cosmic address […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
It might not be an actual supernova remnant, but thanks to 3D printing, it’s the next best thing! This article was written by Kim Kowal Arcand. Kim is the Visualization Lead […]
And what it means if we don’t see gravitational waves from inflation in the next 5–10 years. “The paradigm of physics — with its interplay of data, theory and prediction — is the most powerful […]
There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]
And because of it, we can learn about quantum entanglement across a black hole’s event horizon. This article was contributed to Starts With A Bang by Sabine Hossenfelder, whose blog, Backreaction, […]
According to relativity, there’s no universal frame of reference. But the Big Bang gave us one anyway. “The slow philosophy is not about doing everything in tortoise mode. It’s less […]
A “speculative” theory no more; it’s had four of them confirmed. “Scientific ideas should be simple, explanatory, predictive. The inflationary multiverse as currently understood appears to have none of those […]
Is it possible that our problems indicate a flaw in the theory of gravity? “I soon became convinced… that all the theorizing would be empty brain exercise and therefore a […]
How do we know that the fluctuations in the cosmic microwave background aren’t polluted by everything Hubble reveals? “Silently, one by one, in the infinite meadows of heaven,Blossomed the lovely […]
If String Theory has nothing to do with reality, what are our options? “I just think too many nice things have happened in string theory for it to be all […]
Why “letting there be light” in the Universe isn’t enough. “Dwell on the beauty of life. Watch the stars, and see yourself running with them.” –Marcus Aurelius I want you […]
The Universe is full of surprises. These are the biggest, plus what they mean. “Surprise is the greatest gift which life can grant us.” –Boris Pasternak So it is in […]
If everything began with a Big Bang and is expanding, is there a center? “I want to stand as close to the edge as I can without going over. Out […]
Forget nine lives; if one interpretation of quantum mechanics is right, the cat might have an infinite number of them. Observers are the necessary, but unliked, bouncers in the elegant […]
Encounters in the fourth dimension. We all have an intuitive sense of what a dimension is. There are only three perpendicular directions in which we might move, which we might […]
How new developments in measuring the highest-energy particles and earliest signals from the Universe are teaching us what all this is. Big questions in the field of Cosmology are often […]
What the first signs of life beyond our Solar System will look like. Image credit: Tanga et al., 2012. “Language… has created the word ‘loneliness’ to express the pain of […]
If you’ve been wondering what B-mode polarization is, or how it tells us about gravitational waves from inflation, wonder no more! In part 1 of this story we talked about […]
How the Cosmic Microwave Background — the Big Bang’s leftover radiation glow — continues to shed light on the birth of our Universe. Image credit: ESA and the Planck Collaboration. The announcement of the […]
The scariest of all possible fates results in the ultimate destruction of everything that ever was or will be. Image credit: Boren-Simon 2.8–8 ED POWERNEWT Astrograph Image Gallery. “Why do […]
With all the matter-and-energy so close together and so dense at the moment of the Big Bang, why didn’t it recollapse? Image credit: Mark A. Garlick / University of Warwick. […]
Is there a way to see past the barrier the Universe puts up before it became transparent to light? Image credit: Mark Kamionkowski, of gravitational waves. “From earliest times, humans — explorers […]
Even at the speed of light, you’ll never reach these galaxies. “I realise now that I wanted to disappear. To get so lost that nobody ever found me. To go […]
There have been many supernovae in the Milky Way seen over the past 2,000 years, but nobody ever saw the most recent ones! Image credit: NASA/CXC/NCSU/K.Borkowski et al. “When I […]
Every element found on Earth was made in either the Big Bang or the cores of stars… except these three. “We cannot conceive of matter being formed of nothing, since things […]
It’s the greatest cosmic masquerade of all: a star that fakes its own death! “If you are a dreamer come inIf you are a dreamer a wisher a liarA hoper a […]
