Time might not exist — and we’re starting to understand why

Consider two events, A and B, such as flashes of light made by two sources in different places.

Cause and effect means there are three possibilities: 1) Flash A happened before flash B, and via some mechanism, could have triggered B; 2) Flash B happened before Flash A and could have triggered it; 3) Neither one could have triggered the other because they are too far apart in space and too close in time for a triggering signal to have been sent from one location to the other.

Now, Einstein’s Special Theory of Relativity states that all observers, no matter how fast they’re moving relative to each other, see light travelling at the same constant speed.

This strange but simple fact can lead to observers seeing events happening in different orders.

For option above, two observers moving relative to each other close to the speed of light might disagree on the ordering of flashes.

Thankfully, there’s no danger of an effect coming before its cause (known as a ‘violation of causality’) since the events are too far apart for either to cause the other.

However, what if options and coexisted in a quantum superposition? The causal order of the two events would no longer be fixed.

RAM is so expensive, Samsung won’t even sell it to Samsung

More hints that the Singularity really has begun: and more importantly: https://arstechnica.com/space/2025/12/after-years-of-resisti…ublic-why/

The second article is how Elon is going to have SpaceX go public at $1.5 trillion so he has more money to put into AI. Of course, Elon is not the only one putting money into AI and $1 trillion will be spent on AI data centers next year.

Due to rising prices from the “AI” bubble, Samsung Semiconductor reportedly refused a RAM order for new Galaxy phones from Samsung Electronics.

New state of quantum matter could power future space tech

A UC Irvine team uncovered a never-before-seen quantum phase formed when electrons and holes pair up and spin in unison, creating a glowing, liquid-like state of matter. By blasting a custom-made material with enormous magnetic fields, the researchers triggered this exotic transformation—one that could enable radiation-proof, self-charging computers ideal for deep-space travel.

SPACE4 Ukraine

There are a lot of great charities out there, including space. This is something different.

Imagine; Supporting space education. Giving children in the depths of a war hope and Permission to Dream. Laying the groundwork for an emerging democratic Space Nation by inspiring its children. In other words, doing something that might help the arc of history swing upwards — to the Stars!

In 2017, I traveled across Ukraine on a speaking tour. Even though the country was already at war, what I found wasn’t fear or despair — it was optimism. A fierce, almost defiant belief in the future and democratic values. I met hundreds of young Ukrainians, from teenagers gathered in tech cafés to little kids proudly showing me crayon drawings of the space stations and rockets they dreamed of building someday.

I think about those kids a lot now. I wonder how many of them are gone, how many never had the chance to grow into the engineers, artists, scientists, and explorers they were meant to be. It breaks my heart — and it also drives me to help the ones who are still here, still dreaming, still holding on to hope.

That’s why I launched SPACE4 Ukraine with my partner, Yuliya Kurokhtina — one of Ukraine’s leading business voices and a relentless philanthropist. Together, our mission is simple: give Ukrainian children direction, inspiration, and a reason to believe in their future. The same Permission to Dream that carried me through my own storms.

Most people don’t realize it, but Ukraine has a deep and remarkable space legacy. They helped build Sputnik. They designed the Zenit rockets. They powered Sea Launch. Their engineers remain among the best in the world. This legacy matters — not just historically, but as a beacon for their children: your future can be bigger than your present.

SPACE4 Ukraine is designed to be clear, direct, and transparent.

The case for an antimatter Manhattan project

Chemical rockets have taken us to the moon and back, but traveling to the stars demands something more powerful. Space X’s Starship can lift extraordinary masses to orbit and send payloads throughout the solar system using its chemical rockets, but it cannot fly to nearby stars at 30% of light speed and land. For missions beyond our local region of space, we need something fundamentally more energetic than chemical combustion, and physics offers, or, in other words, antimatter.

When antimatter encounters ordinary matter, they annihilate completely, converting mass directly into energy according to Einstein’s equation E=mc². That c² term is approximately 10¹⁷, an almost incomprehensibly large number. This makes antimatter roughly 1,000 times more energetic than nuclear fission, the most powerful energy source currently in practical use.

As a source of energy, antimatter can potentially enable spacecraft to reach nearby stars at significant fractions of the speed of light. A detailed technical analysis by Casey Handmer, CEO of Terraform Industries, outlines how humanity could develop practical antimatter propulsion within existing spaceflight budgets, requiring breakthroughs in three critical areas; production efficiency, reliable storage systems, and engine designs that can safely harness the most energetic fuel physically possible.

Dynamic duo of bacteria could change Mars dust into versatile building material for first human colonists

Since humanity’s first steps on the moon, the aspiration to extend human civilization beyond Earth has been a central objective of international space agencies, targeting long-term extraterrestrial habitation. Among the celestial bodies within reach, Mars is considered our next home.

The red planet, with its stark landscapes and tantalizing similarities to Earth, beckons as the frontier of human exploration and settlement. But establishing a permanent foothold on Mars remains one of humanity’s boldest dreams and the most formidable scientific and engineering challenge.

The red planet, once draped in a thick atmosphere, has undergone dramatic transformation over billions of years. Its protective blanket vanished, leaving behind an environment nearly unrecognizable to terrestrial life.
