  2. Primordial fluctuations - Wikipedia

    en.wikipedia.org/wiki/Primordial_fluctuations

    At the later stages of radiation- and matter-domination, these fluctuations re-entered the horizon, and thus set the initial conditions for structure formation. The statistical properties of the primordial fluctuations can be inferred from observations of anisotropies in the cosmic microwave background and from measurements of the distribution ...

    The rectenna, approximately 6 kilometers (3.7 miles) in diameter, could be built on land or offshore. And because these mesh structures would be nearly transparent, the idea is the land underneath ...

    The design's strategy was to use the probe to deliver a "seed" factory with a mass of about 443 tons to a distant site, have the seed factory produce many copies of itself there to increase its total manufacturing capacity over a 500-year period, and then use the resulting automated industrial complex to construct more probes with a single seed ...

  5. Inflatable space structures - Wikipedia

    en.wikipedia.org/wiki/Inflatable_space_structures

    Inflatable space structures are structures which use pressurized air to maintain shape and rigidity. The technological approach has been employed from the early days of the space program with satellites such as Echo, to impact attenuation system that enabled the successful landing of the Pathfinder satellite and rover on Mars in 1997.

  6. Space elevator construction - Wikipedia

    en.wikipedia.org/wiki/Space_elevator_construction

    Currently, the cable seeding design and the space manufacturing design are considered. The space manufacturing design would use a carbonaceous asteroid or near-Earth object for mining its material and producing a carbon nanotube cable. [2] The cable would then be transported back to geostationary orbit and spooled down.

    Researchers believe the cavity was formed by an ancient supernovae.

  8. Space architecture - Wikipedia

    en.wikipedia.org/wiki/Space_architecture

    The word space in space architecture is referring to the outer space definition, which is from English outer and space. Outer can be defined as "situated on or toward the outside; external; exterior" and originated around 1350–1400 in Middle English. [4] Space is "an area, extent, expanse, lapse of time," the aphetic of Old French espace ...

    en.wikipedia.org/wiki/Panspermia

    Panspermia (from Ancient Greek πᾶν (pan) 'all' and σπέρμα (sperma) 'seed') is the hypothesis that life exists throughout the Universe, distributed by space dust, [1] meteoroids, [2] asteroids, comets, [3] and planetoids, [4] as well as by spacecraft carrying unintended contamination by microorganisms, [5] [6] [7] known as directed ...
