Over the coming decades, over 100,000 new satellites are expected. For countless millennia, whenever we were faced with a clear, cloudless, moonless night, all of humanity was able to witness […]
Big Think has launched a line of apparel and goods that celebrate the life and work of four geniuses.
Even after our merger with Andromeda, we might retain our spiral shape for trillions of years. You probably don’t think about it very often, but the Milky Way galaxy won’t remain […]
Erik Verlinde has been compared to Einstein for completely rethinking the nature of gravity.
Or is ‘new space’ created in between the gaps of the ‘old’ space? It’s been almost 100 years since humanity first reached a revolutionary conclusion about our Universe: space itself doesn’t […]
We’re not made out of the densest elements, but we’re the densest planet nonetheless. Here’s why. Of all the planets, dwarf planets, moons, asteroids and more in the Solar System, only […]
The Von Braun Space Station, based on the concepts of a controversial scientist, is moving ahead with construction plans.
Enough mass in one location will always create a black hole. But not all masses are possible. If you take enough mass and compress it into a small enough volume […]
New research proposes possible origins of the interstellar object ‘Oumuamua.
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
Since 1957, the world’s space agencies have been polluting the space above us with countless pieces of junk, threatening our technological infrastructure and ability to venture deeper into space.
And which ones are probably examples where we’ve fooled ourselves? Every once in a while — multiple times per year — a new research finding fails to line up with our theoretical expectations. In […]
Even extremely simple configurations in General Relativity cannot be solved exactly. Here’s the science of why. It’s difficult to appreciate how revolutionary of a transformation it is to consider the Universe […]
We need more and better data to know, but that’s exactly what’s coming. Over the past few decades, a number of important advances have helped revolutionize our picture of the Universe. […]
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
At just 3 solar masses, it eliminates the “mass gap.” Searching for black holes is one of the most difficult astronomical games a scientist can play. Emitting no light of their […]
The future of cities on the Moon, Mars and orbital habitats.
For Black Hole Week, NASA released a mesmerizing animation of what a black hole probably looks like.
And, at some point, did the Milky Way lose ours? There are some 400 billion objects flying through the Milky Way galaxy with enough mass that — if they were all made of […]
A colliding star may have triggered the drastic transformation.
Something isn’t adding up, but it isn’t a calibration error. It’s been nearly 100 years since we discovered that the Universe was expanding. Ever since, the scientists who study the […]
Is that required for detectors like LIGO and Virgo to work? Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about […]
Russian astrophysicists propose the Casimir Effect causes the universe’s expansion to accelerate.
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 most massive nearby stars could be the seeds our supermassive black holes need. The problem with the Universe, as we see it today, is that we only get a snapshot […]
If all forms of energy experience gravitation, then why does dark energy make the expansion accelerate instead of slow down? Of all the revolutionary discoveries that we’ve made about the Universe, […]
Want some crazy space phenomena? You don’t have to leave the neighborhood for it.
If you traveled in a straight line for far enough, would you come back to where you started? If you were to set out on a journey from anywhere on Earth’s […]
