Intergalactic Travel with MOND Rockets
Research Notes of the AAS, 2022 Abstract An attractive interpretation of MOdified Newtonian Dynamics as an alternative to dark matter, changes the inertia of matter at accelerations a ≲ a 0 ≈ 1.2 × 10−8 cm s−2. I show that if inertia is modified at low accelerations, this suppresses the exponential factor for the required fuel mass in low acceleration

The Horizon of Future Intergalactic Travel
Research Notes of the AAS, 2023 Abstract I show that non-relativistic objects traveling in intergalactic space at an initial peculiar velocity v will traverse in the future of the LCDM cosmological model a maximum comoving distance of ∼(v/1.7H 0), irrespective of travel time, where H 0 is the Hubble constant.

Cosmic neutrino flux and spin flavor oscillations in intergalactic medium [PDF]
Physics Letters B, 2023 The ultra high energy (UHE) cosmic neutrinos are expected to play a pivotal role in the disquisition of physics beyond the standard model of particle physics as well as serve as an ideal cosmic messengers.

Catching a ride: using hypervelocity stars for interstellar and intergalactic travel [PDF]
Aeronautics and Aerospace Open Access Journal, 2018 Traveling to another star always involves accelerating enough mass to provide habitat, energy, and resources for those who would make the journey. Previous work1,2 looked at how chaotic orbits of a binary asteroid passing near our sun might in very rare ...

Secondary GeV-TeV emission from ultra-high-energy cosmic rays accelerated by GRB 221009A [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2022 The origin of ultra-high-energy cosmic rays (UHECRs) remains elusive. Gamma-ray bursts (GRBs) are among the best candidates able to meet the stringent energy requirements needed for particle acceleration to such high energies.

Warp Drive Concept: Harnessing the McGinty Equation’s Fractal Potential for Faster-Than-Light Travel
International Journal of Theoretical & Computational Physics, 2023 In the realm of theoretical physics and space exploration, the concept of faster-than-light (FTL) travel has long been a tantalizing prospect. The theory of special relativity, developed by Albert Einstein, firmly established the cosmic speed limit: the ...

A long trip into the universe: Psychedelics and space travel
Frontiers in Space Technologies, 2022 Prolonged periods in space have potentially deleterious physiological and psychological effects. Ensuring the physical health and mental well-being of astronauts will inevitably supersede the need for technological innovation, as the major challenge in ...

, 2021 In 1982, MIT physicist Frank Wilczek predicted and named ANYONS, quasiparticles (particle-like formations) that are confined to 2 dimensions and were discovered in 2020. The name might come from Prof. Wilczek's lighthearted comment "anything goes".
