The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?

Eric Olson — CEO and co-founder of Consensus — takes his cues from the university of legendary coaches.
The Universe isn’t as “clumpy” as we think it should be.
Uncertainty is inherent to our Universe.
With such a vast Universe and raw ingredients that seem to be everywhere, could it really be possible that humanity is truly alone?
When cosmic inflation came to an end, the hot Big Bang ensued as a result. If our cosmic vacuum state decays, could it all happen again?
There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life’s final extinction will occur.
The second law of thermodynamics tells us that entropy always increases. But that doesn’t mean it was zero at the start of the Big Bang.
As time goes on, dark energy makes distant galaxies recede from us ever faster in our expanding Universe. But nothing truly disappears.
For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
In all the Universe, only a few particles are eternally stable. The photon, the quantum of light, has an infinite lifetime. Or does it?
From the present day all the way to less than 400 million years after the Big Bang, we’re seeing how the Universe grew up like never before.
U.S. particle physicists recently recommended a list of major research projects that they hope will receive federal funding.
By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe’s star-forming history firsthand.
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
The hot Big Bang is often touted as the beginning of the Universe. But there’s one piece of evidence we can’t ignore that shows otherwise.
How scientists found out that we live in a cosmic aquarium.
Use words with plosives and affricates if you really want to make sure everyone knows you mean business.
Not even Einstein immediately knew the power of the equations he gave us.
The question of why the Universe is the way it is is an ancient one, and none of the answers we have come up with are satisfying.
Frank Wilczek is celebrated for his investigations into the fundamental laws of nature that have transformed our understanding of the forces that govern our Universe. In this video, the MIT […]

In the very early Universe, practically all particles were massless. Then the Higgs symmetry broke, and suddenly everything was different.
As far as we can tell, there’s no limit to how far it goes on; only a limit to how far we can see. Could the Universe truly be infinite?
The JWST’s observations of well-developed galaxies early in universal history may coincide with accepted astronomical theory after all.
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
The majority of the matter in our Universe isn’t made of any of the particles in the Standard Model. Could the axion save the day?
Named “Supernova H0pe,” it shows how JWST plus gravitational lensing can be used to solve the greatest puzzle facing astronomy today.
When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our “lucky stars” enabled our existence.
We can reasonably say that we understand the history of the Universe within one-trillionth of a second after the Big Bang. That’s not good enough.
Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.
