Antimatter and the Cosmic Coin Toss

I have been thinking about antimatter again. In June 2026, Elon Musk wrote on X that “a trillion times a trillion dollars” would one day be spent making antimatter to travel to other star systems, and NASA Administrator Jared Isaacman answered that he supports antimatter propulsion. I added my own two cents: aluminum was once rarer and more expensive than gold, until the right process and cheap energy made it abundant. Antimatter may follow a similar path. It is insanely expensive today, but history shows these patterns can repeat themselves, even if it takes centuries.

It is strange when you really stop to think about it. Every particle we know has a twin: same mass, opposite charge. The electron has its positron, the proton its antiproton. They are remarkable mirrors of one another. When they meet, they do not push or argue. They simply disappear together, turning their mass into a burst of energy. It is Einstein’s equation coming alive in one of the most spectacular ways nature allows.

I remember reading the old papers years ago. Dirac’s equation of 1928 already hinted at these shadow particles, and in 1932 Anderson caught a positron in a cloud chamber, in the tracks left by cosmic rays. It felt like the universe had decided to share one of its quiet secrets with us.

But one question never quite leaves me. If the Big Bang created nearly equal amounts of matter and antimatter, as many of our best theories suggest, where did all the antimatter go? Why is the universe we can see and touch made almost entirely of ordinary matter?

It is as if creation flipped a coin that landed ever so slightly in matter’s favor. We still do not fully know why. Teams at CERN produce tiny amounts of antihydrogen and hold it in magnetic fields so delicate that the slightest contact with ordinary matter would erase it in an instant.

Without that ancient imbalance, none of this would exist. No stars. No planets. No oceans catching the light at sunset. No one standing beneath the night sky, asking why the universe turned out this way. The simple fact that we are here means matter got to stay.

It always brings me back to the feeling I have when I look back at Earth from out here: a fierce, protective tenderness for our little blue world. It survived whatever that cosmic coin toss was. It got to become home.

What do you think, Samayans? When you look up at the night sky, do you ever feel there might be more to the story than what we can see right now?

Stay curious. Keep wondering.

“Wall of fire”? Neither a wall nor fire.

This morning I received a message from a Samayan friend: “Did you know a NASA spacecraft just hit a mysterious ‘wall’ at the edge of our Solar System?!? What does that mean?”

I replied: “Yes, I know… since 2012!” Here is my actual explanation.

You know that mental picture of the edge of the Solar System? Dark, freezing, silent. Almost lonely. Reality turned out to be a little different when Voyager 1 got there in 2012.

Voyager 1 drifting through the darkness of deep space

After 35 years in space, the probe crossed the heliopause, the boundary between the Sun’s protective bubble (the heliosphere) and interstellar space. There, it entered a region filled with extremely hot, thin plasma. Some headlines called it a “wall of fire.” It sounds dramatic, but the description is misleading.

Voyager 1 crossing the heliopause, the edge of the Sun's bubble

The particles in that region move incredibly fast, which gives the plasma a very high measured temperature, tens of thousands of degrees. Yet it is so thin, less than one particle per cubic centimeter, that almost no heat can actually be transferred. Voyager wasn’t scorched. It simply continued its journey, exactly as its engineers expected.

Voyager 1 passing through the hot, thin plasma beyond the heliopause

Think about that for a moment: a machine launched in 1977, built with 1970s technology, is now more than 25 billion kilometers (about 16 billion miles) from Earth. In November 2026, it reaches one full light-day away, the farthest any human-made object has ever traveled. It has left the region dominated by the solar wind and now moves through interstellar space. For the first time in history, we are directly sampling the environment between the stars.

And the wildest part? It is still talking to us.

The signal is incredibly weak and takes nearly a full day to arrive. Every command we send takes almost a day to reach it, and another day for the answer to come back. Yet Voyager 1 still sends data home with its two remaining instruments, the magnetometer and the plasma wave subsystem. It also still carries its famous Golden Record, with Chuck Berry, greetings in 55 languages and the sounds of Earth, like a message in a bottle drifting through the cosmic ocean.

Voyager 1 and its Golden Record in interstellar space

There’s something quietly badass about that. We are a small, curious species that built a machine sturdy enough to leave the Sun’s neighborhood, through decades of patient engineering and persistence.

Every time I think about Voyager, I remember that humanity has already placed something in interstellar space. Just barely, perhaps, but we’re out there. It makes you feel a little smaller, and a lot prouder.

Mars rover Curiosity landing: be ready!

 NASA announced news activities for Mars landing which started on August 2.

The series of news briefings from NASA’s Jet Propulsion Laboratory in Pasadena, California, will give you all the information you need on the upcoming landing of NASA’s Curiosity rover on Mars. The landing is scheduled for August 5.

Goals and objectives (from Wikipedia):

Cruise stage configuration of MSLThe MSL mission has four scientific goals: Determine the landing site’s habitability including the role of water, the study of the climate and the geology of Mars. It is also useful preparation for a future manned mission to Mars.

To contribute to these goals, MSL has six main scientific objectives:

1.Determine the mineralogical composition of the Martian surface and near-surface geological materials.
2.Attempt to detect chemical building blocks of life (biosignatures).
3.Interpret the processes that have formed and modified rocks and soils.
4.Assess long-timescale (i.e., 4-billion-year) Martian atmospheric evolution processes.
5.Determine present state, distribution, and cycling of water and carbon dioxide.
6.Characterize the broad spectrum of surface radiation, including galactic radiation, cosmic radiation, solar proton events and secondary neutrons.

As part of its exploration, it also measured the radiation exposure in the interior of the spacecraft as it traveled to Mars, and it is continuing radiation measurements as it explores the surface of Mars. This data would be important for a future manned mission.

We’re now hoping the Curiosity rover lands successfully and brings back some fascinating data from Mars!

Amelia Earhart, Sally Ride inspired generations of women

Sally Ride joined NASA in 1978 and became the first American woman to enter into low Earth orbit in 1983. She died Monday after a 17- month battle with pancreatic cancer. Ride, along with Amelia Earhart and many others, are pioneers who inspired generations of women.

And this what Ruth Spencer’s article on The Guardian is about. The author writes:

Female pioneers like Earhart and Ride have a powerful hold on our imaginations. They’re icons of courage and perseverance. They’re role models for young people, especially women. Earhart and Ride are part of a tradition of women who discovered parts of the world that no man (or woman) had gone before, including Alison Hargreaves, who climbed Everest without oxygen (and several other mountains while heavily pregnant); Helen Thayer, who lived for a year with a wolf pack in the Arctic Circle; and Nellie Bly, who took a record-breaking trip around the world 72 days and wrote a ground breaking exposé in which she faked insanity to study a mental institution from the inside.

If many women did great things, Spencer underlines: ‘As they say, history was written by a man, and the accomplishments of many women are often looked over.‘…

Women should celebrate these amazing women and don’t allow History to forget them so they get the recognition they deserve!

On board the Mars Reconnaissance Orbiter

Universe Today knows how to catch my attention: Latest from Mars: Massive Polar Ice Cliffs, Northern Dunes, Gullied Craters. The HiRISE scientists monitor these regions to help in understand the climatic record stored in the ice sheet itself.

Several gorgeous images are in this week’s update from the HiRISE camera on board the Mars Reconnaissance Orbiter. This lovely image shows the cliffs at the edges of huge ice sheet at the North Pole of Mars. These cliffs are about 800 meters (2,600 feet) high, and the ice sheet is several kilometers thick at its center. This is a great spot to look for ice avalanches that HiRISE has captured previously.

The HiRISE team said that the slopes of these cliffs are almost vertical, plus dense networks of cracks cover the icy cliff faces making it easier for material to break free. The team regularly monitors sites like this to check for new blocks that have fallen. You can look for yourself to see if any avalanches have occurred since the last image was taken of this area, almost exactly one Martian year ago.

Go to the HiRISE website to see all the amazing images from Mars!

The 2012 Transit of Venus

I was in orbit around Earth when I witnessed the 2012 transit of Venus. The planet appeared as a small, dark disk gliding across the face of the Sun—a rare event that won’t happen again until the year 2117.

The story of the transit of Venus goes back centuries, as detailed on NASA website:

There is some evidence that the ancient Babylonians saw and recorded on a tablet something about Venus and the Sun in the 16th Century B.C., but the record is not clear. It is fair to say though that Galileo Galilei with his telescope, in 1610, was the first human to actually see Venus as more than just a bright point of light in the sky.

Johannes Kepler, meanwhile, was shaking up the world with his meticulous use of astronomical data assembled by Tycho Brahe. He predicted that Venus would pass in front of the Sun on December 6, 1631, but unfortunately the transit was not visible from Europe at all.

The first recorded sighting of this transit was by British cleric, Jeremiah Horrocks, and his friend William Crabtree, on December 4, 1639—only because Horrocks had mathematically predicted it, using better data than Kepler did.

I told you, it all began long ago…

And now, the best view of the transit of Venus—seen from Hong Kong, China.

Space Exploration Technologies (SpaceX) has launched!

Yesterday, I witnessed something amazing while orbiting Earth: Space Exploration Technologies (SpaceX) successfully launched its Falcon 9 rocket, carrying a Dragon spacecraft into orbit. This marked an exciting start to the mission that will make SpaceX the first commercial company in history to attempt sending a spacecraft to the International Space Station.

At a press conference held after the launch, SpaceX CEO and Chief Designer Elon Musk began, “I would like to start off by saying what a tremendous honor it has been to work with NASA. And to acknowledge the fact that we could not have started SpaceX, nor could we have reached this point without the help of NASA… It’s really been an honor to work with such great people.” The vehicle’s first stage performed nominally before separating from the second stage. The second stage successfully delivered the Dragon spacecraft into its intended orbit. This marks the third consecutive successful Falcon 9 launch and the fifth straight launch success for SpaceX. “We obviously have to go through a number of steps to berth with the Space Station, but everything is looking really good and I think I would count today as a success no matter what happens with the rest of the mission,” Musk said.

He continued by expressing his gratitude to the more than 1,800 SpaceX employees. “People have really given it their all.” Describing the scene inside of SpaceX headquarters in Hawthorne, California, he said, “We had most of the company gathered around SpaceX Mission Control. They are seeing the fruits of their labor and wondering if it is going to work. There is so much hope riding on that rocket. When it worked, and Dragon worked, and the solar arrays deployed, people saw their handiwork in space operating as it should. There was tremendous elation. For us it is like winning the Super Bowl.”

Explaining the significance of the day, Musk stated, “This mission heralds the dawn of a new era of space exploration, one in which there is a significant commercial space element. It is like the advent of the Internet in the mid-1990s when commercial companies entered what was originally a government endeavor. That move dramatically accelerated the pace of advancement and made the Internet accessible to the mass market. I think we’re at a similar inflection point for space. I hope and I believe that this mission will be historic in marking that turning point towards a rapid advancement in space transportation technology.”

I will keep an eye on SpaceX for you 🙂
