In 2014, Hari Kunduri and James Lucietti proved the existence of a black hole with Lens space topology of the L(2, 1) type in five dimensions, [2] this was next extended to all L(p, 1) with positive integers p by Shinya Tomizawa and Masato Nozawa in 2016 [3] and finally in a preprint to all L(p, q) and any dimension by Marcus Khuri and Jordan ...
An iron star is a hypothetical type of compact star that could occur in the universe in the extremely far future, after perhaps 10 1500 years. The premise behind the formation of iron stars states that cold fusion occurring via quantum tunnelling would cause the light nuclei in ordinary matter to fuse into iron-56 nuclei.
A launch loop (or Lofstrom loop) is a dynamically supported 2000 km long iron loop that projects up in an arc to 80 km that is ridden by maglev cars while achieving orbital velocity. StarTram Generation 2 is a maglev launch track extending from the ground to above 96% of the atmosphere's mass, supported by magnetic levitation.
The structures are listed based on their longest dimension. This list refers only to coupling of matter with defined limits, and not the coupling of matter in general (such as, for example, the cosmic microwave background, which fills the entire universe). All structures in this list are defined as to whether their presiding limits have been ...
Pietronero argues that the universe shows a definite fractal aspect over a fairly wide range of scale, with a fractal dimension of about 2. [3] The fractal dimension of a homogeneous 3D object would be 3, and 2 for a homogeneous surface, whilst the fractal dimension for a fractal surface is between 2 and 3.
Astronaut Sally K. Ride became the first American woman to visit space in June 1983. Calandrelli said she was crying on the flight home from the mission because of the online reaction and texting ...
The cosmological evolution of the void regions differs drastically from the evolution of the universe as a whole: there is a long stage when the curvature term dominates, which prevents the formation of galaxy clusters and massive galaxies. Hence, although even the emptiest regions of voids contain more than ~15% of the average matter density ...
After years of anticipation, on Nov. 22, the mother of two from West Virginia not only achieved that dream but also made history as the 100th woman to travel to space with Blue Origin.
