Category: INTERNATIONAL RELATIONS
1. Biden rolls out asylum restrictions to help ‘gain control’ of the border
Syllabus: Effect of Policies and Politics of Developed and Developing Countries on India’s Interests
Mains: Migration as decisive factor in U.S. Election
Introduction:
- President Joe Biden unveiled plans to impose significant restrictions on migrants seeking asylum on the U.S.-Mexico border.
- The move aims to address immigration as a political liability ahead of the November elections.
Presidential Proclamation Details:
- The order will be enacted when border encounters between ports of entry reach 2,500 per day.
- Migrants arriving at the border without expressing fear of returning to their home countries will face immediate removal.
Political Context:
- Biden’s proclamation follows the collapse of a bipartisan border security deal in Congress.
- Most Republican lawmakers rejected the deal, influenced by former President Donald Trump, the presumptive Republican Party presidential nominee.
- Biden stated that he preferred legislative action but accused Republicans of leaving him no choice but to act unilaterally.
- Biden emphasised that “immigration has always been the lifeblood of America.”
Reaction and Implementation:
- Trump criticised Biden on social media, accusing him of surrendering the Southern Border and claiming the order was merely for show.
- The order’s implementation will subject migrants without expressed fear of return to immediate removal, possibly facing a five-year re-entry bar or criminal prosecution.
- Migrants expressing fear or seeking asylum will undergo screening by a U.S. asylum officer under stricter standards than currently used.
Nut Graf: President Joe Biden announced new asylum restrictions at the U.S.-Mexico border to address immigration issues and political pressures. The order enforces the immediate removal of certain migrants and implements stricter screening for asylum seekers amid rising border encounters.
2. Western Europeans question reliability of United States: survey
Syllabus: Effect of Policies and Politics of Developed and Developing Countries on India’s Interests
Mains: Declining credibility and legitimacy of the U.S. worldwide
Context:
- A survey by the Eurasia Group’s Institute for Global Affairs revealed low confidence among Western Europeans in the United States’ reliability for security.
- Only 6% of respondents from Britain, France, and Germany believe the United States will be a “very reliable” guarantor of European security over the next decade.
- In contrast, 24% of Americans view their country as very reliable in this regard.
Comparison with Previous Years:
- This survey is the first time the question about U.S. reliability has been asked in the annual survey.
- The results are surprising given President Joe Biden’s strong support for Ukraine against the Russian invasion over the past two years.
Factors Influencing Doubts:
- Mark Hannah, a senior fellow at the institute, finds the low confidence levels remarkable despite the United States’ significant contributions.
- The primary reason for the scepticism is likely former President Donald Trump’s stance on NATO and aid to Ukraine, which he has criticized as wasteful and unfair to the U.S.
American Perspective: While Western Europeans show low confidence, a higher percentage of Americans (24%) believe in their country’s reliability in guaranteeing European security.
Nut Graf: A survey by the Eurasia Group’s Institute for Global Affairs reveals that only 6% of Western Europeans consider the United States a “very reliable” guarantor of their security, reflecting doubts influenced by former President Trump’s critical stance on NATO and Ukraine aid.

Category: SCIENCE AND TECHNOLOGY
1. With bad news from Cassini, is dark matter’s main rival theory dead?
Syllabus: Developments in Science and Technology, Applications of scientific developments in everyday life
Prelims: Cassini, dark matter
Mains: The concept of dark matter
Context:
- One of the most profound mysteries in astrophysics is the rotational behaviour of galaxies, which do not align with predictions based on Newton’s laws of gravity. To account for the discrepancies, the concept of dark matter was proposed.
- However, an alternative theory, Modified Newtonian Dynamics (MOND), suggested that these anomalies could be due to a breakdown of Newton’s laws under specific conditions. Recent findings, however, challenge the viability of MOND.
The Concept of Dark Matter
- Origin: Proposed to explain why galaxies rotate faster than expected without flying apart.
- Nature: An invisible, exotic substance not accounted for in the Standard Model of particle physics.
- Detection: Despite extensive efforts, dark matter has not been directly observed.
Introduction to MOND
- Proponent: Israeli physicist Mordehai Milgrom in 1982.
- Principle: Suggests Newton’s laws of gravity alter under very weak acceleration, typical at the edges of galaxies.
- Successes: Predicts galaxy rotation curves without invoking dark matter and has a few other successes.
Testing MOND
- Key Hypothesis: MOND effects should be noticeable at low accelerations, regardless of the distance.
- Observational Strategy: By examining deviations in celestial bodies’ orbits, MOND can be tested.
Issues
Findings from the Cassini Mission
- Objective: Use Cassini’s data to track Saturn’s orbit and test for MOND-induced anomalies.
- Results: No deviations were found; Newtonian gravity held true.
- Implications: Challenges the core predictions of MOND.
Other Recent Challenges to MOND
- Wide Binary Stars: MOND predicted faster orbits, which have been ruled out by recent studies.
- Outer Solar System Bodies: Observations of comets and other small bodies also do not match MOND predictions.
- Galaxy Clusters: MOND fails to explain the gravitational behaviour both in the central and outer regions of galaxy clusters.
Significance
Implications for Astrophysics
- Validation of Newtonian Gravity: Reinforces the reliability of Newtonian mechanics over MOND on various scales.
- Dark Matter: Despite its elusiveness, dark matter remains the prevailing explanation for galactic dynamics.
- Theoretical Revisions: Prompts reconsideration of MOND and highlights the necessity for new theoretical frameworks or modifications.
Solutions
Enhancing Dark Matter Detection
- Advanced Instruments: Invest in more sensitive detection technologies.
- Collaborative Research: Foster international collaboration for large-scale dark matter experiments.
Re-evaluating Theories
- Theoretical Exploration: Develop new models that might incorporate aspects of both dark matter and modified gravity.
- Interdisciplinary Approaches: Utilise advancements in particle physics, cosmology, and computational simulations.
Nut Graf: The recent findings from the Cassini mission and other studies present significant challenges to MOND, suggesting that it cannot be considered a viable alternative to dark matter. While the concept of dark matter continues to hold sway, the exact nature and detection of dark matter remain crucial areas of ongoing research.
