Up until this point, scientists have slowly chipped away at the fantasy of faster-than-light (FTL) travel by relying on theories of bizarre physics and exotic matter. Now, another astrophysicist has delivered an equally exciting warp drive breakthrough. Just last week, scientists dropped a bombshell when they unveiled the first physical model for a warp drive, the holy grail of space travel that would allow us to bend the fabric of space and time to their will and overcome the vast distances separating humans from the stars.

The new design reimagines the shape of warped spacetime to allow for normal matter and energy to be used instead.Previous warp drive designs relied on a source of exotic matter unknown to physics.An astrophysicist has created a theoretical design of a warp drive that uses conventional physics.

The first indications of changes in the structure of some sources were obtained by an American-Australian team in a series of transpacific VLBI observations between 19 (Gubbay et al. In the introduction to a workshop on superluminal radio sources, Pearson and Zensus reported The apparent velocity is obtained by multiplying the observed proper motion by the distance, which could be up to 6 times the speed of light. The discovery was the result of a new technique called Very Long Baseline Interferometry, which allowed astronomers to set limits to the angular size of components and to determine positions to better than milli-arcseconds, and in particular to determine the change in positions on the sky, called proper motions, in a timespan of typically years. In 19 such sources were found as very distant astronomical radio sources, such as radio galaxies and quasars, and were called superluminal sources. In 1966 Martin Rees pointed out that "an object moving relativistically in suitable directions may appear to a distant observer to have a transverse velocity much greater than the velocity of light". His discovery was published in the German journal Astronomische Nachrichten, and received little attention from English-speaking astronomers until many decades later. Superluminal motion was first observed in 1902 by Jacobus Kapteyn in the ejecta of the nova GK Persei, which had exploded in 1901. Perrine studied this phenomenon using photographic, spectroscopic, and polarization techniques.”

Thought to be a nebula, the visual appearance was actually caused by light from the nova event reflected from the surrounding interstellar medium as the light moved outward from the star. telescope (Crossley), he discovered the apparent superluminal motion of the expanding light bubble around Nova Persei (1901). Perrine’s photograph of November 7th and 8th, 1901, secured with the Crossley Reflector, led to the remarkable discovery that the masses of nebulosity were apparently in motion, with a speed perhaps several hundred times as great as hitherto observed.” “Using the 36-in. The apparent superluminal motion in the faint nebula surrounding Nova Persei was first observed in 1901 by Charles Dillon Perrine. If the distance of the object from the Earth is known, the angular speed of the object can be measured, and we can naively calculate the speed via:Īpparent speed = distance to object ×, the only velocity on the sky that we can measure, is larger than the velocity of light in vacuum, i.e. In tracking the movement of such objects across the sky, we can make a naive calculation of their speed by a simple distance divided by time calculation. Superluminal motion occurs as a special case of a more general phenomenon arising from the difference between the apparent speed of distant objects moving across the sky and their actual speed as measured at the source.
