2 second delay at the merger of two neutron stars in August 2017

In summary, new papers have been published discussing the processes involved in the collision of two neutron stars in August 2017. Some people have questioned the 2-second delay between gamma rays and gravitational waves, but there is no clear explanation for it yet. One possible explanation is that the gamma rays are slowed down by the debris from the merger. However, a 2017 study did not provide any significant progress in understanding this delay, so we may have to wait for the next neutron star merger for more information.

Some new papers appeared about processes in the collision of the two neutron stars, measured in August 2017.

Is now more clear, why 2 second delay between gamma rays and gravitational waves happens?

Possible explanation - gamma rays are slowed down by passing through the debris of the merger.

1. What is the significance of the 2 second delay at the merger of two neutron stars in August 2017?

The 2 second delay at the merger of two neutron stars in August 2017 was a groundbreaking discovery in the field of astrophysics. It provided evidence for the existence of gravitational waves, which were predicted by Einstein's theory of general relativity but had never been directly observed before.

2. How was the 2 second delay measured?

The 2 second delay was measured using gravitational wave detectors, specifically the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo detector. These detectors use laser beams to detect tiny changes in the fabric of space-time caused by passing gravitational waves.

3. What caused the 2 second delay in the neutron star merger?

The 2 second delay was caused by the collision of two neutron stars, which are incredibly dense objects formed from the collapsed cores of massive stars. As the two neutron stars spiraled towards each other and eventually merged, they released a burst of gravitational waves that took 2 seconds to reach Earth.

4. Why is the timing of the 2 second delay important?

The timing of the 2 second delay is important because it provides valuable information about the properties of neutron stars and the nature of gravity. By measuring the delay, scientists can better understand the behavior of these extreme objects and test the accuracy of Einstein's theory of general relativity.

5. What implications does the 2 second delay have for future research?

The 2 second delay has opened up a new avenue of research in the study of gravitational waves and neutron stars. It has also sparked interest in the possibility of using neutron star mergers as a "standard candle" for measuring cosmic distances. This discovery has the potential to greatly advance our understanding of the universe and its origins.
