After previously discussing surveillance and autonomous cars, Singularity University’s Brad Templeton returns to Big Think to examine some lighter fare: quantum mechanics and computing.
If they’re so massive that not even light can escape, how can we see them? “According to the special theory of relativity nothing can travel faster than light, so that […]
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 […]
Brad Templeton discusses the vast computational power that a quantum computer could have, provided that someone were to build one.

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 […]
How one of the first tests of special relativity might lead to the greatest particle accelerator of all-time. “One feels that the past stays the way you left it, whereas […]
Through a clever experiment, researchers at the Massachusetts Institute of Technology have arrived at a closer understanding of the foundation of the human imagination.
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 […]
Want more realistic sci-fi? Consult a scientist. Here’s how you get access. “The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.” –Isaac […]
The densest, most massive objects in the Universe will live an awfully long time, but not forever. Here’s what happens to them. Image credit: Gemini Observatory/AURA illustration by Lynette Cook. […]
Before the first star ever formed, the Universe was filled with light. But how? “Light thinks it travels faster than anything but it is wrong. No matter how fast light […]
We’ve only ever seen 2nd-generation stars and later. Until, just maybe, now. “For my part I know nothing with any certainty, but the sight of the stars makes me dream.” […]
After the CMB, before the first stars, there was nothing to see. Or was there? “[I]f there were no light in the universe and therefore no creatures with eyes, we […]
How the demons and angels of our greatest minds advanced science. Image credit: Luis Royo Fantasy Art, via Photobucket user mikenolan78. When most people think of Einstein, they think of […]
Whether or not you believe there’s a problem, we’re all part of the solution. “Bad men need nothing more to compass their ends, than that good men should look on […]
Sure, the Universe is expanding, and that expansion is accelerating. But beyond simply calling the cause “dark energy,” what do we know about it? Image credit: NASA, ESA, H. Teplitz […]
In most respects, neurology’s attack on free will seems to have won the day, not the least reason being that randomness is a far cry from making free and intentioned decisions.
Spoiler: NO, not a chance. Now find out why. “There is, I believe, in every disposition a tendency to some particular evil, a natural defect, which not even the best […]
Live-streamed from Perimeter Institute, & exclusive real-time commentary! “Every generation of physicists solves some old puzzles and finds some new ones.” –Dr. Kendrick Smith I want you to think back […]
What makes the Sun shine? For decades, the science didn’t add up. “Every time we get slapped down, we can say, ‘Thank you, Mother Nature,’ because it means we’re about […]
Saw “Solar System Questions” by xkcd? Here’s what science thinks it knows. “Put two ships in the open sea, without wind or tide, and, at last, they will come together. […]
Is there a limit to how small a length can be? Image credit: Sabine Hossenfelder. Good ideas start with a question. Great ideas start with a question that comes back […]
Light and sound are waves that we all know. But gravity makes them, too. “Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, […]
On his blog, Caltech physicist Sean Carroll explains how if you accept quantum mechanics, it is not difficult to accept the multiple universes hypothesis.
A person is, in large part, the sum of their habits. We go through an evolutionary process each day, in which certain behaviors in our repertoire are selected for and […]
How a fundamental but unstable particle might be our first window into particle physics beyond the Standard Model. Image credit: Muon g-2 magnet, courtesy of Fermilab. “You suddenly realize that […]
When you work, do you often use a computer? If the answer is yes, then the specific answer is: you use a classical computer. That is what your machine is […]
The observer changes everything, but what does that mean? “You can observe a lot by just watching.” –Yogi Berra In our everyday lives, things happen the way they happen, and whether […]
We claim to know the Universe’s history to incredible precision. But is this justified? “The only reason for time is so that everything doesn’t happen at once.”-Albert Einstein We’ve reached […]
