Strange Viscous Stars May Be Mimicking Black Holes

Fast Summary

• Researchers suggest that highly viscous stars could reflect gravitational waves, producing signals similar to those of black holes.
• Gravitational waves, ripples in the universe’s fabric, have been studied as 2015 to understand cosmic phenomena.
• Calculations by Jaime Redondo-Yuste’s team propose that a spherical star with high viscosity might act as a mirror for gravitational waves.
• Stars reflecting gravitational waves would need extreme viscosity and compactness, near-collapse into a black hole-like state.
• While black holes are currently known to be highly viscous, these findings allude to the possibility of other objects mimicking their gravitational wave patterns with subtle variations.
• Potential candidates could include hot neutron stars formed from neutron star mergers, but none fully match the mathematical model yet.
• Future advancements in gravitational wave detection technology may help identify such exotic stars or provide better clarity on their existence.
• Researchers acknowledge that observational evidence for these stars is lacking and their likelihood of being detected remains low.

Indian Opinion Analysis
The hypothesis regarding highly viscous stars contributing new insights into how we perceive celestial bodies through gravitational waves is notable from both research and technological perspectives. It challenges prevailing assumptions about cosmic phenomena like black holes while expanding possibilities for what else might exist in our universe’s inventory. For India-a nation striving toward greater involvement in space exploration-the study highlights opportunities for collaboration on international projects like advanced detectors (e.g., LIGO) or enhancing domestic research capacities related to astrophysics and quantum science.

These findings also encourage Indian scientists to explore niche areas within theoretical physics that intersect fields like materials science (to simulate “viscosity” conditions) or cosmology-domains yielding immense educational merit alongside innovation potential.
