The Physics of Interstellar Travel - UFO Evidence
This essay will explain the challenges of interstellar travel, the prospects and limitations of existing propulsion ideas, and the prospects emerging from science that may one day provide the breakthroughs needed to enable practical interstellar voyages. Analogies to familiar science fiction are used to simplify notions such as the 'warp drive'.
The Physics of Interstellar Travel - UFO Evidence
Some scientists tend to scoff at the idea of interstellar travel because of the enormous distances that separate the stars. According to Special Relativity (1905), no usable information can travel faster than light locally, and hence it would take centuries to millennia for an extra-terrestrial civilization to travel between the stars.
The ETH and the Likelihood of Interstellar Travel - UFO Evidence
The (un)likelihood of extraterrestrial visitation is probably one of the most debated aspects of the Extraterrestrial Hypothesis, the answer being an essential component to the validity of the ETH. After all, the assumed unlikeliness of interstellar travel has become the cornerstone of those who resist the ETH as an explanation for UFOs.
SETI, the Velocity-of-Light Limitation, and the Alcubierre Warp …
Key words: SETI, velocity of light, general relativistic dynamics, space-time metric, interstellar travel, vacuum energy, Casimir effect, vacuum engineering, warp drive, superluminal travel SETI researchers routinely subscribe to the view that interstellar travel between civilizations is exceedingly improbable due to the velocity-of-light ...
Looking to Lasers, Microwaves and Anti-Matter for Space Travel
Nov 26, 2003 · Laboratories scattered around the world are delving into novel and exotic forms of propulsion. Breakthrough physics could well make possible ambitious human treks across interstellar distances. Work is underway to harness antimatter as a way to shave travel time to the Moon down to minutes, or between Earth and Mars to a day.
SpaceTime Hypersurfing - UFO Evidence
In some future history, 1994 may be remembered as the year that the warp drive was first conceived to be a physical possibility. Long a cliche' of science- fiction writing, the warp drive has transported countless fictional characters through light-years of interstellar space in the time it takes for you or me to travel to the market.
Scientists Try to Prove a Higher Speed of Light - UFO Evidence
May 30, 2000 · And the principle that nothing can go faster would mean most science-fiction tales of interstellar travel are impossible. At that speed, it would take us many generations to reach even the closest galaxies. Now, however, physicists are coming closer to finding out how, in some situations, light may actually travel faster than that.
"Where Is Everybody?": An Account of Fermi's Question
Part of the current debate about the existence and prevalence of extraterrestrials concerns interstellar travel and settlement [1-3]. In 1975, Michael Hart argued that interstellar travel would be feasible for a technologically advanced civilization and that a migration would fill the Galaxy in a few million years [4].
Anti-gravity propulsion comes ‘out of the closet’ - UFO Evidence
Boeing, the world’s largest aircraft manufacturer, has admitted it is working on experimental anti-gravity projects that could overturn a century of conventional aerospace propulsion technology if the science underpinning them can be engineered into hardware.
Reaching for Interstellar Flight - UFO Evidence
Furthermore, these craft lack the power sources or communications gear that a true interstellar probe would require. More to the point -- you don't have to be a rocket scientist or an astronomer to appreciate the fact that space is vast, said Steven Howe, co-founder and chief executive officer of Hbar Technologies, LLC, based in West Chicago ...
