Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
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, […]
There are a lot of unsolved mysteries in the Universe, but dark energy is the most confusing. Here’s why. The majority of the energy in our Universe went completely undiscovered until […]
Forget about alien nonsense. The Universe as it actually is doesn’t need any embellishments to be interesting. In our Solar System, the planets, moons, asteroids, comets and other masses are […]
100+ years ago, General Relativity came along, and Einstein gave the Universe a cosmological constant. Here’s why that was a mistake. Back in the 17th century, Isaac Newton put forth the […]
The origin story for our Universe got a major revision nearly 40 years ago. Time to catch up. 13.8 billion years ago, all the matter and energy contained within our Universe […]
If you think that the Moon is only good for reflecting sunlight, you’ve got another think coming. To human eyes, the Moon is the second brightest visible object, trailing only the […]
Or, quite possibly, is it more complex than either one of those scenarios? If there’s one lesson that humanity should have learned from the 20th century, it’s this: the Universe […]
A recent headline claimed they could. But if gamma-rays are just a form of light, don’t they have to travel at light-speed? There’s an ultimate speed limit in the Universe: […]
She’s not a scientist, an expert, or even an adult. But she’s got one good lesson to teach us all. Like most people on Earth, Greta Thunberg is not a climate […]
As more data comes in, the puzzle gets deeper and deeper. Whenever you set out to solve a problem, there are a series of steps you have to take in order […]
You might think that we live in a three dimensional Universe based on space alone. But you cannot leave time out of it. If you were asked to describe how you […]
Electron-positron or proton-proton colliders are all the rage. But the unstable muon might be the key to unlocking the next frontier. If you want to probe the frontiers of fundamental […]
The darkness of the night sky was a mystery for generations of humans. Here’s the reason why. From our perspective here in the Solar System, it makes absolute intuitive sense why […]
And one of our planets has the orbiting moons to prove it. Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an […]
The top of Mauna Kea is the ideal physical site for this new, ready-to-be-built telescope. But that’s far from the only concern. For many years, astronomers have looked forward to a […]
And it’s not because of leap seconds; it’s a fundamental property of most days. Human beings, in marking the passage of time, account for each day equally: with 24 hours. One […]
And does it require the idea of ‘negative gravity’ in order to work? The biggest question that we’re even capable of asking, with our present knowledge and understanding of the Universe, […]
Just because you can design an experiment to test for something doesn’t mean you should trust the results. Is there another Universe out there? The Universe we know and inhabit, the […]
It’s very different from the colloquial meanings of “true-and-false” or “right-and-wrong.” In many ways, the human endeavor of science is the ultimate pursuit of truth. By asking the natural world […]
At the core of the largest star-forming region of the Local Group sits the biggest star we know of. Mass is the single most important astronomical property in determining the lives […]
