Fast Radio Bursts (FRBs) are rapid and intense bursts of radio emissions from deep space.

What are  Fast Radio Bursts?

– FRBs are intense bursts of radio    emissions lasting only    milliseconds. – Detected as sudden spikes in    radio waves from deep space,    emitting as much energy as the    sun in a day.

The Mystery of Fast Radio Bursts

– Despite numerous observations,    scientists are still uncertain    about the cause of FRBs. – Their rarity and brief duration    make them challenging to study    and locate accurately.

Potential Sources of Fast Radio Bursts

– Leading theory: FRBs emitted by    highly energetic neutron stars    with intense magnetic fields. – Repeating FRBs suggest objects    that survive the emission,    supporting the neutron star    hypothesis.

Black Holes

– Speculative theory: FRBs may be    emitted due to intense    gravitational fields around black    holes. – Challenges: Warped space-time    around black holes makes    detailed observation difficult.


– Magnetars, highly magnetized    neutron stars, are considered as    sources of FRBs. – Detection of an FRB from a    magnetar in the Milky Way    galaxy provides strong evidence    for this theory.

Colliding  Neutron Stars

– When neutron stars collide, they    release intense radiation,    potentially including FRBs. – Gravitational waves and gamma    rays detected from a neutron    star collision in 2017 support this    theory.

Alien Communication

– Controversial theory: FRBs might    be attempts at communication    from advanced extraterrestrial    civilizations. – Scientists propose methods to    search for patterns or    sequences in FRBs as potential    signs of intelligent life.
