Gamma-Ray Bursts Reaching The Speed Of Light Are Traveling Back In Time

Back in 2018, some gamma-ray burst pulses seemed to be going backward in time. Today researchers Jon Hakkila of the College of Charleston and Robert Nemiroff of the Michigan Technological University presume that the explanation is the waves that travel faster than light. Superluminal speeds could cause the time reversibility effect.

A physical process is time-reversible if the dynamics of the process remain well-defined when the sequence of time-states is reversed.

Superluminal motion is caused by the jets traveling very near the speed of light towards the observer. Because the high-velocity jets are emitting light at every point of their path, the light they emit does not approach the observer much more quickly than the jet itself, giving the illusion of faster-than-light travel.

Gamma-ray bursts are extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several hours. After an initial flash of gamma rays, a longer-lived “afterglow” is usually emitted at longer wavelengths.

Gamma-Ray Bursts At The Speed Of Light Travel Back In Time

The intense radiation of most observed GRBs is thought to beSpeed Of Light released during a supernova or super-luminous supernova as a high-mass star implodes to form a neutron star or a black hole. It has been suggested that gamma-ray bursts could conceivably represent optical illusions caused by constant emitters entering into the region of space-time occupied by a gamma emitter.

Cherenkov radiation is electromagnetic radiation emitted when a charged particle passes through a medium at speed higher than the phase velocity of light in that medium. It creates a luminal gloom, like a blue glow.

Due to Cherenkov radiation, when a particle traveling at near light-speed enters the water can hypothetically appear to be in two places at once: one image looking to move forward in time and the other appearing to move backward. This is the effect researchers believe occurs with the gamma-ray burst pulses that seem to be going back in time.

Mathematical modeling was conducted by the two astrophysicists to demonstrate how it could work. “In this model, an impactor wave in an expanding gamma-ray burst jet accelerates from subluminal to superluminal velocities, or decelerates from superluminal to subluminal velocities,” they say.

The research is far from being over, and it can be put to an end by details like the transparency of the plasmas involved. If they aren’t transparent to superluminal radiation, years of work can be moved to the recycle bin.
