The speed of electromagnetic radiation is a constant. Its value is exactly
299,792,458 metres per second (about 186,282 miles per second) in vacuum,
somewhat slower in material media.
To give you some kind of a feeling for that speed, it would be the equivalent
of 7 1/2 times around the Earth in one second.
The speed is the same for all electromagnetic radiation. Gamma rays are one form
of it. Others include radio, microwave, visible light, ultraviolet, X-rays, etc.
The speed of light (3x10^8 m/s) as it is an electromagnetic wave and they all travel at this speed in a vacuum. This number can be used for gases as well as the molecules are so spread out at normal temperatires
Same as speed of light "C". Gamma Rays are also form of Electro Magnetic Radiations
All EMR incl Light travel at same speed in same medium.
Which is normally approximated to 3 x 10^8 m/s
That depends on the type of radiation and sometimes where it comes from. Electromagnetic radiation (gamma rays, xrays, light rays etc) all travel at the speed of light; 3 x 10^8 m/s , regardless of their source. Beta rays & alpha rays are particles and can have any speed , less then the speed of light. Their speed will depend on their source.
radiation (heat) from the sun also travels at the speed of light
Gamma rays are electromagnetic radiation, physically identical to radio, heat, light, microwave, etc., but with shorter wavelength (higher frequency).
They travel at the 'speed of light': 300 million meters (186 thousand miles) per second.

The amplitude of a gamma-ray burst refers to the peak brightness of the burst. It is the measure of how intense the burst is at its peak emission. Gamma-ray bursts are extremely energetic and can release more energy in seconds than the sun will emit in its entire lifetime.
A gamma-ray burst is a brief and extremely energetic explosion of gamma rays that comes from deep space. It is thought to be generated when massive stars exhaust their nuclear fuel and collapse into a black hole or neutron star, releasing a huge amount of energy in the process.
A gamma-ray burst can release as much energy in a few seconds as the Sun will emit over its entire lifespan of about 10 billion years. They are one of the most energetic events in the universe.
Gamma ray bursts can reach temperatures of several billion degrees Kelvin, making them one of the hottest events in the universe. The energy released during a gamma ray burst can be more than a supernova explosion and can outshine the entire galaxy for a brief moment.
Gamma rays can travel long distances through space, potentially millions of light years, due to their high energy and lack of mass. On Earth, the distance gamma rays can travel depends on the material they encounter, with higher-energy gamma rays penetrating further than lower-energy ones. In dense materials like lead, gamma rays may only penetrate a few centimeters, while in air they can travel several meters.
The black holes from Gamma ray usually burst because of their energetic form.
Earth gets hit every day by gamma-ray bursts - from far, far away. Depending on how near the gamma-ray burst is, it may cause some serious damage.
Mega Disasters - 2006 Gamma Ray Burst 2-3 was released on: USA: 18 September 2007
The earth would be completely destroyed.

At our current level of technology absolutely nothing.
Light ray and gamma ray both travel in a straight line.
A gamma ray burster emits an amount of gamma ray energy in one pulse roughly equal all EM radiation energy of a galaxy in a year. So yes.
If a gamma ray burst hit Earth, it could potentially strip away the ozone layer, leading to an increase in harmful ultraviolet radiation from the sun. This could have catastrophic effects on the environment and life on Earth. However, the likelihood of a gamma ray burst hitting Earth directly is very low.
A gamma ray burst results from an extremely energetic implosion/explosion, as in supernovae or hypernovae events, or the less likely possibility of the combination of 2 neutron stars.
