Exploring the Unexplained in the Cosmos

Fast Radio Bursts (FRBs)

Fast Radio Bursts are intense, millisecond-duration radio pulses originating from distant galaxies. Their origin remains one of the biggest mysteries in modern astrophysics.

The extreme distances involved make pinpointing FRB sources exceptionally difficult. Theories range from magnetars – highly magnetized neutron stars – undergoing violent events to exotic objects like cosmic strings.

λ = c/f  (Wavelength, frequency, speed of light)

Dark Objects and Relativistic Motion

Observations of distant galaxies exhibiting peculiar velocities – movement significantly faster than predicted by gravitational interactions with visible matter – have led to the concept of ‘dark flow’.

This suggests a large-scale coherent motion driven by an unknown force, potentially involving dark energy or structures beyond our current cosmological models. Calculations often involve relativistic speeds and distances.

v = dt/ds (Velocity, time, distance)

Microlensing Events

Gravitational microlensing occurs when a massive object passes directly between us and a more distant light source. This can dramatically brighten the background star.

Anomalous events observed through this process, like objects exhibiting unusually rapid lensing times or multiple lensing paths, challenge our understanding of dark matter distribution and potentially point to new types of compact objects.

F = (M*G)/(r^2)  (Flux, mass, gravitational constant, distance)

The ‘Missing’ Mass Problem

The anomalous motion of galaxies and galaxy clusters strongly suggests the existence of large amounts of unseen matter – dark matter. However, the precise nature of this dark matter remains elusive.

Theoretical models involving Warm Dark Matter (WDM) - particles with higher velocities than cold dark matter - attempt to explain these discrepancies, though observational evidence is still debated.
