Black hole triple system

🅾️Firstly read this-
Life cycle of a star- https://youtu.be/f2SUWOkzTlc

🅾️Binary vs Triple system : Binary systems consist of two gravitationally bound objects, like a black hole and one star, orbiting around a common center of mass. A triple system involves three objects bound by gravity, which is less stable than a binary system because of the complex gravitational interactions among three bodies.

🅾️Why Are Triple Systems Unusual for Black Holes?-Because supernova explosions usually disrupts nearby objects, scattering them, so it’s unusual for two stars to remain gravitationally bound

Click here

🅾️What is the point of this article?- Biomass power is an underutilized energy resource in India- So we need to promote National Bioenergy Programme (NBP)

🅾️Use cases : Biomass has the potential to produce biogas, biofuels, and compressed natural gas (CNG), which can support India’s transportation and agricultural sectors. There is also demand for bio-based products like fertilizers-The government is targeting 15% blending of green hydrogen with natural gas by 2025 and aims to establish bio-CNG as an alternative fuel source. This demonstrates that biomass could significantly contribute to energy independence if effectively utilized.

Gs-2 : Fundamental Rights- Minority Rights

🅾️Funda that we must not forget
- Education laws must balance the state's interest in standardizing educational norms and protecting minority rights to maintain secularism and religious freedom.

⚠️Legal question here?-
Whether the U.P. Madrasa Act's provision allowing madrasas to award degrees up to post-graduate level infringed on the UGC Act of 1956 and other educational norms.

🔰SC answer- Yes it did- this was found to be in breach of the UGC Act, which standardizes higher education in India. Minority institutions have the right to manage their educational affairs, this right DOES NOT extend to functions that are regulated under uniform laws like the UGC Act.

Gs-2 : Fundamental Rights - Status of Right to property

🅾️Context?- Article 31 of the Constitution initially guaranteed the right to property as a Fundamental Right but was repealed by the 44th Amendment in 1978, relegating it to a legal right under Article 300A.

⚜️Article 39(b) emphasizes that material resources of the community must be controlled to serve the "common good."The scope of "material resource of the community" is interpreted to include public resources that have a broad impact on community welfare (e.g., forests, minerals).

🔰Recent Supreme Court ruling shifted from a socialist economic model to a liberalized economy perspective, limiting the state's power to acquire personal effects for redistribution unless justified by public necessity.

⚜️⚠️Implication?- The evolution underscores a shift from state-centric to market-oriented governance

Gs-2 : Fundamental Rights- debate on minority rights - AMU case


⚠️Legal interpretation uses both literal and purposive approaches
.

🅾️The literal approach Azeez Basha case(1967),- AMU not a minority institution-Why?-> AMU is estd by Parliament- not muslim community

⚜️1981 AMU Amendment Act- AMU's minority status retained-> But fundamental question remained: Is the act of establishment the sole criterion for minority status, or should the institution's purpose and functioning be considered?

🅾️2024- SC's Purposive approach- new “holistic and realistic” test - > purpose over mere technicality

🌟1. Establishment Criterion: Whether the institution was originally set up for the benefit of a minority.

🌟2. Administrative Control and Function: Whether it continues to serve the educational and cultural needs of that minority, aligning with the spirit of Articles 29 and 30.

Gs3- power-Infra- Renewable energy - Wind Energy

🅾️What is the funda here?- Wind turbines convert wind energy into electricity, but as these machines age, their efficiency declines, meaning they produce less energy than newer, more advanced turbines.
Tamil Nadu, a leader in wind energy in India, has many turbines over 30 years old, limiting their output and reliability

🅾️Core Solutions -

⚜️1. Repowering- replacing older, smaller turbines (those over 15 years old and <2 MW capacity) with newer, higher-capacity turbines and

⚜️2. Refurbishment: Upgrades specific components to extend the lifespan and improve the efficiency of existing turbines. This option is cost-effective and minimizes installation challenges

Gs-4 : Ethical dilemmas- Concept of freewill

🅾️At its core, free will is the ability to make choices without being constrained by external forces (physical, social, or psychological).

🅾️So what is the issue?- Humans are often limited by various factors—biological needs, societal pressures, legal frameworks, and personal relationship

🅾️Freedom can be both personal (one's ability to make individual choices) and social (freedom within society). However, society often prioritizes collective harmony over individual freedom
⚠️BUT- From an evolutionary perspective, freedom (to a degree) enables humans to adapt and cooperate for survival. However, absolute freedom could disrupt social cohesion

🚫Freedom is shaped by our biology, society, and moral beliefs, making the "will" semi-free—free within the limits imposed by our environment and nature.
