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 highest energy collisions go beyond any collider… and may hold a fantastic secret! This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity. […]
Even most of the pros don’t know all 10. This post was contributed to Starts With A Bang by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
In 30 million years, we’ll undergo star formation unlike anything else since before there were mammals on Earth. “Think about it this way — a boomerang goes out and comes back to you […]
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, […]
Traveling to the future is possible, but the “back” part runs into trouble. Mr. Strickland: “I noticed your band is on the roster for the dance auditions after school today. […]
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 […]
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 […]
We know that Einstein’s general relativity is superior to Newton’s gravity, but where did Newton go wrong? “To me there has never been a higher source of earthly honor or […]
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 […]
And how, if we manage to harness it on Earth, it could be the most accurate probe in all of scientific history. “We… are what happens when a primordial mixture […]
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 […]
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 […]
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 […]
The fastest way to make interstellar travel a reality might not be only science fiction for long! It is humanity’s longstanding dream to venture to the stars. We long to […]
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 […]
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. […]
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 […]
No other idea explains even two of these. Image credit: NASA / CXC / ESO WFI / Magellan composite. Any recent article about the remaining mysteries of the Universe will […]
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 […]
What is Punk? Punk isn’t about mohawks or studded leather, says Henry Rollins – it’s about resistance to tyranny in any form. How Art Can Change Society, with Sarah Lewis Sarah […]
The quantum nature of the Universe ruins everything. “What we observe is not nature itself, but nature exposed to our method of questioning.” –Werner Heisenberg When you think about the […]
It’s all relative, but what you might have seen probably isn’t accurate. “There is no such thing as perpetual tranquillity of mind while we live here; because life itself is […]
A forgotten almost-hero of the 19th century still has something to teach about science… and style. “There is nothing more contemptible than a bald man who pretends to have hair.” –Martial […]
And what they mean for humans here on Earth. “Concentrate all your thoughts upon the work at hand. The sun’s rays do not burn until brought to a focus.” –Alexander […]
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 […]
How afraid of them does the science say you should actually be? “Most estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying […]
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 […]
When all the galaxies, stars, gas, dust, dark matter and all the other forms of matter and radiation are summed together, its energy still pales in comparison to dark energy. […]
