* Or new physics (dark energy changes)

### WHY IT MATTERS

* Challenges current cosmological models
* Could lead to new physics discoveries

### EXAM ANGLE

GS III (Science & Tech)
👉 *“What is Hubble tension and why is it significant?”*

---

4. Right to Vote vs Right to Contest

### WHAT HAPPENED

* SC clarified distinction amid voter roll deletion disputes

### CORE CONCEPT

* Right to vote ≠ Fundamental Right
* Right to contest = statutory right

### KEY DETAILS

1. Why is the Strait of Hormuz critical to global energy flows?

WHAT HAPPENED

• Rising US-Iran tensions led to restrictions and threats around Strait of Hormuz
• Shipping movement reduced sharply, raising global energy security concerns

CORE ISSUE / CONCEPT

• Maritime chokepoints = narrow sea routes where large volumes of global trade pass
• Strait of Hormuz = world’s most critical oil transit chokepoint

KEY DETAILS

• ~21 million barrels/day oil (~20% global consumption) passes through

• Nearly 80% energy flows through route go to Asia (India, China, Japan, South Korea)
• Narrow width: ~21 nautical miles
• Other chokepoints: Strait of Malacca, Bab el-Mandeb, Suez Canal, Panama Canal

WHY IT MATTERS

• Disruptions → spike in oil prices + inflation + supply chain shocks
• Direct impact on India’s energy security (heavy import dependence)
• Strategic vulnerability in global trade routes

INTERNATIONAL LAW ANGLE

• Governed by UNCLOS (Law of the Sea)
• Principle of “transit passage” → ships can pass freely
• Coastal states can regulate safety but cannot block passage
