Surprisingly, the evidence points towards the existence of the unobservable multiverse. But it isn’t the answer you’re looking for. “We are all agreed that your theory is crazy. The question that […]
If humans were made in God’s image, then whose image were aliens made in? A simple, innocent question that I received had me thinking for days about how to answer it. […]
The ‘big event’ was billed as a first in 150 years. But is what we’re seeing really that rare? This January 31st, something quite rare and special will happen. At 1:30 […]
It’s so much more than mass-energy equivalence; it’s the key to unlocking the quantum Universe. For hundreds of years, there was an immutable law of physics that was never challenged: […]
What it would take to make a ‘mirror Universe’ a reality. The idea of parallel Universes has been around for over 60 years now, giving a theoretically physical existence to all […]
If nothing can escape from beneath the event horizon, where do these phenomena come from? The most important feature of a black hole is that it has an event horizon: a […]
Would there be only blackness past the event horizon? Or something more? Black holes are some of the most perplexing objects in the entire Universe. Objects so dense, where gravitation […]
There’s nothing new, recent, or remarkable about it. It’s just a typical cosmic pebble in the galactic ocean. Last year, the interstellar interloper ʻOumuamua passed through the inner Solar System. Originally […]
The neutron star-neutron star merger was initially only seen in 1 detector out of 3. Here’s how scientists didn’t let it slip away. On August 17th, 2017, a gravitational wave event […]
Even if it can’t detect them directly, we’ll learn the answer. Here’s how. Perhaps the most revolutionary find of the past generation, when we think about the Universe beyond Earth, is […]
The deep dive into the mirror Universe, and the ethics of how we deal with purity and diversity, is just getting started. Life in the mirror Universe isn’t easy for anyone. […]
What do our future missions in physics, astronomy, astrophysics and more hold? If you went back in time just 30 years, the world as we it was a completely different place. […]
Are we looking for life in all the wrong ways, like SETI with smoke signals? A little over 80 years ago, humanity first began broadcasting radio and television signals with enough […]
They’re less than a billion years old. And, thanks to ALMA, they might finally pave the way to understanding how galaxies form. How do galaxies like our Milky Way come to […]
Multiple teams of scientists can’t agree on how fast the Universe expands. Dark matter may unlock why. There’s an enormous controversy in astrophysics today over how quickly the Universe is expanding. […]
There is no reason for science and faith to be hostile to one another. If you want to figure out how the Universe works, you have to ask. Not by asking […]
Last week, the crew found themselves in the mirror Universe. Here’s what science has to say about that. Star Trek: Discovery entered their midseason hiatus on a terrific cliffhanger: they had […]
They’re the fastest rotators of all. So how distorted are they? There are very few objects in the Universe that stand still; almost everything we know of rotates in some way. […]
If nature makes equal amounts of matter and antimatter, how are we here? When you look out at the vastness of the Universe, at the planets, stars, galaxies, and all there […]
Combining nanotechnology of two different varieties might be the game-changer we’ve always dreamed of. For as long as human beings have been writing about fantasy, myth, and science fiction, the dream […]
A cosmic controversy is back, and at least one camp — perhaps both — is making an unidentified error. Ever since Hubble first discovered the relationship between a galaxy’s distance and its motion away […]
What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]
This list of 10 non-winners is 50% women, but 100% outrageous. In science, advances often come in great leaps. In hindsight, it’s easy to identify perhaps hundreds of small steps […]
Aiming for the nearest star would necessitate a whole slew of advances. Even if the mission fails, humanity wins by investing in itself. There have been some magnificent moments in NASA […]
The truth might not be ‘out there’ at all. There may never have been another intelligent, technologically advanced alien species in the entire history of the Universe. When you take into […]
The Event Horizon Telescope has come online and taken its data. Now, we wait for the results. Black holes are some of the most incredible objects in the Universe. There are […]
How did black holes get so supermassive so fast? Astrophysics may be about to find out, thanks to three big 2017 discoveries. There’s a big problem when we look at […]
From the birth and deaths of stars to the largest structures in the Universe, Hubble shows us what we’d never see otherwise. When it comes to the Universe itself, perhaps […]
Out of five vital questions, which one should we most desire the answer to? Despite all we’ve learned about physics, science, and the Universe before us, there are still some incredibly […]
What does science have to say about the biggest questions about existence of all? Find out on our new Starts With A Bang podcast. Ever wonder about the biggest questions that […]
