Artificially modified craniums are pretty common in the ancient record. Anton Petrov — a YouTube content creator who focuses on math and science — gets this right.
But the lack of information available now compared to 100 years ago made it harder for him to find all the important data.
So I don’t hold it against him. Instead, I’ll use it as a chance to keep this memory alive. Here’s more from Dedunking.
Did we just get a greeting from Proxima Centauri? Scientists at the Search for Extraterrestrial Intelligence (SETI) confirm they’ve received an unusual alien signal from the Proxima Centauri system, the star closest to our sun.
What makes the discovery so exciting is the location of the solar system, which is home to an exoplanet in its habitable zone, and that it originated from the world’s biggest technosignature investigation project known as Breakthrough Listen, which collaborates with NASA to search for advanced extraterrestrial life. The signals were originally detected in early 2019, but scientist have just recently identified it. Here’s more with YouTuber Anton Petrov.

The total number of galaxies in the visible, observable universe is much higher than we thought. Surprisingly, if you began a raw count of one galaxy per second right now, you probably would reach about three billion near the end of your life.
Common knowledge in the scientific world puts the inexact number of galaxies at around 100 to 400 billion, not counting those in the invisible universe that is beyond our reach. And this idea of an observable universe is important, because the cosmos is expanding and what once were the edges are now disappearing beyond our view.
Although there are galaxies beyond our reach that we will never observe, we have our hands full with those we can view. And, scientists note, they come in a variety of shapes and sizes. Here’s more with Anton Petrov.

An enormous asteroid sharing the same orbit as Mars, may very well be a lost chunk from our moon. Not only does it possess a completely different composition than other asteroids orbiting Mars and nearby planets, but it also has an identical structure of some parts of the lunar surface.
Anton Petrov, host of What Da Math, says the Mars asteroid-moon connection is theory at the moment, but definitely warrants a space mission to gather samples from the rock. “We might be able to discover other mysteries about the moon and, of course, the Earth as well,” he says. Here’s more with Petrov.

A recent study has scientists tepidly excited about possible habitable planets outside our solar system. Not only has the study honed in on 24 candidates in the universe, but also our future homes that are more habitable than Earth.
We’re talking super-habitable exoplanets equipped with properties that are even better suited for life than Planet Earth. These planets possess just the right conditions for liquid water, better conditions for life to evolve for billions of years and they all orbit just the right kind of star that’s not too active or cold.
The study reveals that when it comes to the type of star that is ideal, our sun is not perfect. Labeled a G-type star, scientists say our sun doesn’t have enough life left in it–only about 5 billion years–not much time by universe standards. And scientists point out that in the next 2 billion years it will reach conditions where life on Earth will not be possible anymore. So the study is gravitating more to K-type stars, which can last for 80 billion years, enough time for life as we know it to evolve.
Because the 24 planets are still labeled as “candidates,” scientists are not entirely sure if they’re out there. Only two have been confirmed, only nine are orbiting a K-type star and 16 are more than a few billions years old, meaning they are well-suited to maintaining the necessary conditions. But only five of these have the all-important temperature conditions.
The big downer in the study is that every one of these planets is too far away–more than 100 light-years (each light-year is 5.88 trillion miles). And the most promising–exoplanet KOI 5715.01–is nearly 3,000 miles away. Here’s more on the study and our potentially future home with Anton Petrov.

Employing the seldom-used gravitational lensing technique, scientists has discovered what they are calling a “Super Earth,” smack in the middle of our Milky Way Galaxy, near the galactic bulge. Anton Petrov, host of “What Da Math,” says the discovery was an extremely rare event, since the host star of the planet is a red dwarf, which are usually small and dim. The star is approximately 12 percent the mass of the sun and the Super Earth is about four masses of Earth. “We don’t really know if it’s a gas world, but it’s somewhat more likely to be an unusual, somewhat ice-like planet with similar conditions to maybe Neptune or Earth.”

The European Space Observatory has just announced that it has discovered the closest black hole to Earth. The discovery is in the star system HR6819, about 1,000 light years (each light year is equal to about 6 trillion miles) from our planet. Host Anton Petrov provides the details in this episode of What Da Math.

Finally, science has confirmed the existence of a distant, intermediate massive black hole in a galaxy approximately 740 million light years away. The first hint of this discovery actually came in 2006, when scientists detected some X-ray bursts powerful enough to indicate something was being destroyed. With the help of the massive Hubble Space Telescope, it was confirmed there was only one plausible explanation for this activity–it was likely an intermediate massive black hole destroying a star, creating a tremendous amount of energy in the process. Host Anton Petrov brings us more in this episode of What Da Math.

Surprisingly, the Asian Flu of 1957-58 and the Hong Kong Flu of 1968-69 each killed more than 1 million people and coincided with the solar maximum, the sunspot activity when solar activity is at its highest. With the onset of COVID-19 and Swine Flu earlier in the century, it makes you wonder if there’s some sort of a relationship between these pandemics and solar activity that we’re not seeing. In a 1990 article, Nature magazine explained that there are a lot of viruses in our upper atmosphere, which are carried closer to the surface of the planet by solar winds, thus increasing the chance of infections and pandemics. But is there solid evidence to prove the connection or is this just coincidence? Host Anton Petrov of What Da Math explains further and reaches a conclusion.

Our Milky Way Galaxy is enormous, almost 126,000 light years in length. To put it in perspective, that’s approximately 756 trillion miles long! Amazing. Thing is, we are labeled an intermediate galaxy in our known universe. And we are very tiny in comparison to IC 1101, the largest galaxy with an approximate diameter of 6 million light years, a little more than 60 times larger than our Milky Way. In this episode of “What Da Math,” host Anton Petrov takes us on a surreal journey through IC 1101.
