Billions of years from now, the universe as we know it will cease to exist. The good news is, that gives us a lot of time to prepare, and maybe even figure out a way to cheat cosmic death. Here are some possible ways our descendants might survive a cosmological apocalypse.
“Space is big,” said Douglas Adams. “You just won’t believe how vastly, hugely, mind-boggingly big it is.” But why must this be so? And why does our Universe exhibit such tremendous scale, from the very tiny to the extremely large? Here are some possible answers.
Katie Silver has penned an article for BBC Earth in which she explores the idea of finding a single theory that describes the entire Universe. But as her article aptly points out, it's a challenge that appears to be getting increasingly difficult.
According to the Many Worlds Interpretation of quantum physics, we live in an infinite web of alternate timelines. It's a serious claim that carries some rather serious scientific, philosophical, and existential baggage. And here are the nine weirdest possible implications.
An analysis of 583 cultures shows that challenging environmental conditions, such as floods and famines, lead cultures to adopt beliefs in moralizing, high gods. The research may help explain how and why certain religions emerged, including Judaism, Christianity, and Islam.
Embodied cognition theory states that our thoughts and emotions are profoundly affected by our physical bodies. A new study takes this idea further, claiming that our bodily states — particularly when they're urgent — can even influence our metaphysical beliefs.
In this video from TED-Ed, James Zucker teams up with Stretch Films' John R. Dilworth to dish out a cogent, three-minute introduction to René Descartes' Meditations on First Philosophy. If you've ever wondered how to get from "How do I know I'm real?" to "I think, therefore I am," this one's for you.
Philosopher Nick Bostrom's famous Simulation Argument suggests it's highly probable that we live inside a supercomputer. But one philosopher takes this hypothesis to task, arguing in a new paper that there are other post-human scenarios that need to be taken into account.
Agnostics are often characterized as ambivalent or wishy-washy fence sitters who refuse to make up their minds. But there's much more to agnosticism than these tired misconceptions, including a stricter adherence to scientific principles than those typically invoked by atheists.
The Internet has given us a kind of digital afterlife, where our online activities can be preserved and memorialized like fossils in a rock. We talked to an expert about how your friends, family, and complete strangers will use the Internet to remember you long after you're gone.
Philosophy goes where hard science can't, or won't. Philosophers have a license to speculate about everything from metaphysics to morality, and this means they can shed light on some of the basic questions of existence. The bad news? These are questions that may always lay just beyond the limits of our comprehension.
It's tempting to think of the universe as a meaningless repository for celestial objects like planets and stars. But an intriguing theory suggests there's much more to the cosmos than meets the eye — and that black holes play an integral role in what our universe is actually trying to achieve.
Nietzsche is famous for saying that God is dead, but news of The Almighty's demise may have been greatly exaggerated. Here are some of the most fascinating and provocative philosophical arguments for the existence of God.
We're still decades — if not centuries — away from being able to transfer a mind to a supercomputer. It's a fantastic future prospect that makes some people incredibly squeamish. But there are considerable benefits to living a digital life. Here's why you should seriously consider uploading.
How would we know if time travelers are visiting the present? You could look for clues — but the best indication might be found on the internet. Unfortunately, two researchers tried to look for clues to time travel online... and came up with nothing.
New research on wormholes suggests that these theoretical shortcuts that connect distant points in the universe might be linked with the spooky phenomenon of quantum entanglement. As Charles Q. Choi writes in LiveScience, this would allow particles to be connected regardless of how far apart they are — a finding that…
Doctor Who’s TARDIS is unique in that it appears larger on the inside than it does from the outside. According to scientists from the University of Helsinki, our universe may exhibit similar properties, a phenomenon they're dubbing Tardis spacetime. It’s a new theory that could solve a longstanding mystery in…
Our universe appears to be bound by a finite set of laws, yet we often talk about things that go on for an eternity. "Infinity" is a strange idea. But it's crucial if you want to understand anything from philosophy to mathematics. Here’s why.
The Many Worlds Interpretation of quantum physics has been around for nearly 60 years. It’s a highly controversial idea which suggests that our world — and everything in it — is constantly splitting into alternative timelines. If it's correct, here's what your true existence might actually be like.
Conventional thinking says the Universe has been expanding ever since the Big Bang. But theoretical astrophysicist Christof Wetterich says it's not expanding at all. It’s just that the mass of all the particles within it is steadily increasing.
