🔆 LIGO-India (Laser Interferometer Gravitational-Wave Observatory)
📍 Latest Update (Feb 2026)
✅ Larsen & Toubro (L&T) won the contract from Department of Atomic Energy (DAE) to construct LIGO-India at Aundha, Hingoli district, Maharashtra.
🔆 About LIGO
📍 Objective
✅ Detect Gravitational Waves — ripples in space-time caused by violent cosmic events like black hole mergers or neutron star collisions.
✅ Predicted by Albert Einstein in 1916 (General Theory of Relativity).
✅ First directly detected in 2015 at LIGO Laboratory, USA.

🔆 U.S.–Saudi Civil Nuclear Deal: Strategic & Non-Proliferation Concerns
📍 Why in Focus?
✅ The proposed U.S.–Saudi Arabia civil nuclear deal has sparked concerns over nuclear proliferation, Middle East geopolitics, and the future of the Abraham Accords.
📍 Key Highlights
✅ Saudi Arabia seeks nuclear energy to support Vision 2030, diversify its economy, and free more oil and gas for exports.
✅ The deal reportedly permits a peaceful nuclear programme but leaves ambiguity regarding uranium enrichment on Saudi soil.

✅ Critics argue the deal may weaken the global nuclear non-proliferation regime and further complicate regional tensions with Iran.
📍 Concerns
✅ No mandatory adoption of the IAEA Additional Protocol, limiting international safeguards and inspections.
✅ Enrichment capability could increase the risk of future nuclear weaponisation.
✅ Changing U.S. conditions have reduced Saudi confidence and may harden Iran’s negotiating position.
📍 UPSC Value Addition
✅ NPT: Recognises the right to peaceful nuclear energy while preventing nuclear weapons proliferation.
✅ IAEA Additional Protocol: Expands inspection powers and strengthens verification of peaceful nuclear activities.
✅ Abraham Accords (2020): Agreements normalising relations between Israel and several Arab states.
