What Is the Geometry of the Universe?
In our mind’s eye, the universe seems to go on forever. But using geometry we can explore a variety of three-dimensional shapes that offer alternatives to “ordinary” infinite space.

How to Make the Universe Think for Us
Physicists are building neural networks out of vibrations, voltages and lasers, arguing that the future of computing lies in exploiting the universe’s complex physical behaviors.

We will never be able to live on another planet. Here’s why
The scientific evidence is clear: the only celestial body that can support us is the one we evolved with. Here’s why
What time is it on the Moon?
Satellite navigation systems for lunar settlements will require local atomic clocks. Scientists are working out what time they will keep.

Why Not Mars (Idle Words)
It's slow, expensive, the engineering is mostly port-a-potty chemistry, and the best-case outcome is that thirty years from now we’ll get to watch someone remotely operate a soil scoop from Mars…

What's the real reason you can't go faster than the speed of light?
The real reason that we cannot travel faster than light speed is far more interesting than the textbook answer.
«On the bright side, now that you know about spacetime, the next time your boss gets on your case for just sitting there, you can tell them that they are being unreasonable. You’re moving as fast as possible.»
How fast is gravity, exactly?
Thanks to observations of gravitational waves recorded in 2017, we now know that gravity and light travel at the same speed.
Brightest-Ever Space Explosion Could Help Explain Dark Matter
A recent gamma-ray burst known as the BOAT — “brightest of all time” — appears to have produced a high-energy particle that shouldn’t exist. For some, dark matter provides the explanation.
Scientists Created a Black Hole in The Lab, And Then It Started to Glow
A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.
A student asked her cosmology professor the meaning of life. Here was his response.
In this excerpt from "Cosmogenesis," cosmologist Brian Thomas Swimme explains how physics can approach questions about meaning in life.
«We are universe. The universe made us. In a most primordial way, we are cosmological beings.»
Long Articles
These are some of the most-read long-form articles in Space.
Why scientists can't give up the hunt for alien life
There will always be "wolf-criers" whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
Why 21 cm is the magic length for the Universe
Photons come in every wavelength you can imagine. But one particular quantum transition makes light at precisely 21 cm, and it's magical.
Is dark matter's "nightmare scenario" true?
The great hope is that beyond the indirect, astrophysical evidence we have today, we'll someday detect it directly. But what if we can't?
Can science ever discover the absolute truth about reality?
Is science absolute? Its truths and discoveries guide us towards the nature of reality, but we must always remain open-minded to revisions.
The race to reclaim the dark
Some 200 places around the world have now achieved Dark Sky status. Frankie Adkins explores the benefits nights with out light pollution can bring.

What is Refind?
Every day Refind picks 5 links from around the web for every user, tailored to the user’s interests. Picking only a handful of links means focusing on what’s relevant and useful. We favor timeless pieces—links with long shelf-lives, articles that are still relevant one month, one year, or even ten years from now. These lists of the best resources on any topic are the result of years of careful curation.
How does Refind curate?
It’s a mix of human and algorithmic curation, following a number of steps:
- We monitor 10k+ sources and 1k+ thought leaders on hundreds of topics—publications, blogs, news sites, newsletters, Substack, Medium, Twitter, etc.
- In addition, our users save links from around the web using our Save buttons and our extensions.
- Our algorithm processes 100k+ new links every day and uses external signals to find the most relevant ones, focusing on timeless pieces.
- Our community of active users gets 5 links every day, tailored to their interests. They provide feedback via implicit and explicit signals: open, read, listen, share, add to reading list, save to «Made me smarter», «More/less like this», etc.
- Our algorithm uses these internal signals to refine the selection.
- In addition, we have expert curators who manually curate niche topics.
The result: lists of the best and most useful articles on hundreds of topics.
How does Refind detect «timeless» pieces?
We focus on pieces with long shelf-lives—not news. We determine «timelessness» via a number of metrics, for example, the consumption pattern of links over time.
How many sources does Refind monitor?
We monitor 10k+ content sources on hundreds of topics—publications, blogs, news sites, newsletters, Substack, Medium, Twitter, etc.
