$62.5 TRILLION per gram. That’s how much antimatter costs—making it the most expensive substance on Earth. Why? Because it can unleash 100% pure energy on contact. Imagine fueling spaceships or curing cancer with it.

But here’s the twist: we can barely make any. Only a few nanograms per year… and it disappears if not perfectly contained.

This material could change the world

Here’s why:

India has taken a giant leap in affordable space technology. Agnikul Cosmos, a Chennai-based startup, successfully launched its Agnibaan SOrTeD rocket—powered by the world’s first single-piece 3D-printed rocket engine. This innovation isn't just a technical milestone—it signals a new era of low-cost, high-impact aerospace development. Designed and built entirely in-house, the engine simplifies manufacturing and increases reliability by eliminating joints and welds.

This achievement also highlights India’s growing influence in the global private space sector. As nations race to commercialize space, Agnikul's model could enable smaller countries and private players to enter orbit without billion-dollar budgets. Backed by support from ISRO and IIT Madras, the startup has demonstrated that with the right mix of talent and technology, space access can be democratized—even from a university lab in Chennai.

Elon Musk has activated Starlink satellite internet over Iran in response to widespread government-imposed internet blackouts triggered by escalating Iran–Israel tensions.

The move was confirmed by Musk with a post saying, “The beams are on,” indicating Starlink coverage was live in Iranian airspace.

-- Why It Matters

Iran has recently faced major internet shutdowns due to regional instability and internal crackdowns. Starlink’s activation is intended to restore independent internet access for Iranians during this communication crisis.

-- Who Can Access It?

Despite the satellite signals being active:

Only those with Starlink terminals can access the service.

Terminals are not legally sold or distributed in Iran, so access is largely limited to people who already have the equipment or can smuggle it in, such as activists or tech-savvy citizens.

-- Historical Context

This is not the first time Starlink has supported Iranians:

In 2022, Musk offered similar support during anti-government protests in Iran.

The U.S. government eased sanctions back then to allow tech services like Starlink to assist civilians.

Einstein-Rosen Bridge: Theoretical Gateways Through Spacetime

First proposed in 1935 by Albert Einstein and Nathan Rosen in their landmark paper “The Particle Problem in the General Theory of Relativity,” the Einstein-Rosen (ER) bridge—commonly referred to as a wormhole—is a theoretical construct that suggests a tunnel or shortcut linking two distant regions of spacetime.

Core Concepts of the ER Bridge
Mathematical Framework: ER bridges are not physical structures but mathematical solutions to Einstein’s field equations, describing how two separate regions of spacetime might be connected.

Wormhole Anatomy: Visualized as a tunnel with two ends or "mouths," the ER bridge forms a passage through spacetime, known as a throat.

Spacetime Shortcuts: These bridges imply the possibility of instantaneous travel between distant cosmic locations—at least theoretically.

Theoretical Significance
Quantum Gravity Connection: ER bridges play a key role in efforts to unify general relativity and quantum mechanics—an ongoing quest in modern physics.

Topology of the Universe: They challenge conventional ideas of spacetime structure, offering new perspectives on how different points in the universe might be intertwined.

Legacy and Influence
Wormhole Exploration: The concept of the ER bridge laid the foundation for modern wormhole research, sparking interest in both science and science fiction.

Impact on Physics: It remains a powerful idea in theoretical physics, influencing debates around quantum entanglement, black holes, and the fabric of reality itself.

On October 15, 2023, NASA’s Juno spacecraft captured stunning new images of Io’s north pole—a region barely seen in detail before. Thanks to the powerful JunoCam, three towering volcanic peaks near the day-night boundary were revealed for the first time, expanding our understanding of this fiery Jovian moon.

At just 7,270 miles (11,700 km) above Io’s surface, Juno’s eye caught features that earlier missions like Voyager and Galileo missed. Citizen scientist Ted Stryk then enhanced the raw data, bringing these volcanic giants into sharp focus.

This fresh glimpse of Io’s volcanic activity offers exciting clues about one of the most geologically active worlds in our solar system!
