Based on current evidence, which of the following statements about gamma ray bursts is true? Gamma ray bursts are highly energetic explosions which have so far been observed at extremely distant galaxies. 

They are by far the most powerful and brightest electromagnetic events known to take place in the universe. Bursts can last up to ten seconds and can result in a huge amount of energy. Released in a very short time. These gamma rays are thought to originate from a galaxy cluster known as the Galactoscope.

Gamma ray bursts are known for their shockwave-like arrival and fast speed.

They are caused by supernovae explosions. Which are extremely violent events in which huge amounts of matter (and in some cases light) explode in a spectacular explosion. That can reach several billions of light years away. The matter created is in the form of shock waves that can travel long distances through the vacuum of space. Impacting other galaxies and sending shock waves which create gamma ray bursts. This phenomenon also creates gamma particles, which are high energy, and extremely rapid too. This is the reason that these bursts have such a high energy level.

One of the characteristics of gamma-ray bursts is their very high frequency of radio or microwaves. 

To put it in simple terms, they are not gamma rays. So we are looking at very fast gamma rays. Which have a very high probability of decimating or destroying anything in their path. It is the afterglows which are potentially very destructive. They can kill or damage the surfaces on which they burst. And in large enough afterglows the surface of the planet itself can be destroyed. As was the case with Halong Bay in Myanmar.

We know from our satellite studies that they tend to occur very close to black holes. However, there is still much to discover about them. Scientists are not entirely sure how these gamma ray bursts are triggered in the first place. Although we do know that some explosions do appear to be caused by black hole explosions. It seems that the afterglows are a secondary event. Brought on by a nearby exploding star or by something in the nearby atmosphere.

The light from the burst travels through our magnetosphere and gets reflected back to earth.

For the scientists who study these phenomena it is fascinating to see the way these short events may bring about particles into our solar system. They can also affect the evolution of gases and may play a role in helping create a new generation of planets around other stars. Studying these gamma ray bursts and studying the subsequent effect they have on outer space is an important part of the mission of NASA’s Near Earth Orbit (NEO) science investigation.

The main areas where scientists study terrestrial gamma-rays are by tracking the radio transmissions bounced off of other satellites in space. 

These frequencies are very narrow, and they can only be detected very close to the surface of the receiving satellite. The last super-fast terrestrial gamma-ray burst was in March 2021, when a communication satellite in space sent out a series of radio communications to researchers on the ground, but the signals were decoded before reaching their destination. Since then we have been busy trying to pinpoint the exact spot where this one burst originated from.

Super-fast gamma rays were produced as the result of a shockwave or large explosion inside a black hole. 

There is also some speculation that they could come from explosions near or on a gas or rock of mass near a black hole. It is possible that these bursts are a result of a binary pulsar, which is a highly magnetized radio pulsar that emits gamma rays in a variety of forms, including X-rays, gamma, radio, and microwaves.

If this is the case then we may have found a way to detect and map these explosions before they happen. This could make it easier to find other gamma-ray bursts and to track them as they travel through space. In fact, our very research and observatory technology could make this detection possible, which is why it is so important to fund these space research programs now, before they go bankrupt. Please consider all this.
