Time To Replace America’s Land-Based ICBMs
Posted by Bruce Dorminey in category: nuclear weapons
The U.S.’ land-based ICBM arsenal will have to be replaced by the mid-2030s with a totally new missile. The land-based missiles remain a crucial component of the nuclear triad.
America’s land-based ICBM arsenal remains the backbone of its nuclear deterrence efforts, but it still needs a total replacement.

The “Door’ To Another Universe…Can We Find The Black Hole That Opens It…Physicists Say “Yes!”
Posted by Andreas Matt in categories: cosmology, information science, mathematics, physics
According to a mind-bending new theory, a black hole could actually be a tunnel between universes, meaning our universe may be nested inside a black hole that is part of a larger universe. The theory explains that the matter doesn’t collapse into a single point, but rather gushes out a “white hole” at the other end of the black one.
The theory was published in the journal Physics Letters B, by Indiana University physicist Nikodem Poplawski. In his article, he presents new mathematical models of the spiraling motion of matter falling into the black hole. His equations suggest that wormholes are probable alternatives to the “space-time singularities” originally predicted by Albert Einstein.
Einstein’s equations for general relativity suggest singularities are created whenever matter in a given region gets too dense as would happen at the center of a black hole. Singularities are infinitely dense and hot, and take up no space. This idea has been supported by indirect evidence but has never been fully accepted into the scientific community.

Stratolaunch aircraft with wingspan length of FOOTBALL FIELD unveiled
Posted by Dan Kummer in category: transportation
Microsoft co-founder Paul Allen unveiled the world’s largest aircraft on Wednesday.
The massive plane rolled out by Allen’s aerospace firm, Stratolaunch Systems, features the longest wingspan of any aircraft ever built, according to Popular Mechanics.
With a wingspan of 385 feet, the six-engine plane will be larger than Howard Hughes’ 1947 H-4 Hercules, known as the ‘Spruce Goose,’ and the Antonov An-225, a Soviet-era cargo plane originally built to transport the Buran space shuttle that is currently the world’s largest aircraft.

Cassini images suggest asteroid strike forced Enceladus poles to shift
Posted by Dan Kummer in categories: asteroid/comet impacts, existential risks
NASA has announced that asteroid strikes may have tipped over Saturn’s icy, ocean-bearing moon Enceladus. Researchers came to the conclusion after analysing the latest images and data from Cassini.
Researchers say they have enough evidence to suggest the moon’s spin axis – the line through the north and south poles – reoriented from its original position due to a collision with a smaller body, most likely an asteroid. The shift from its original axis is by 55 degrees, more than halfway rolling completely onto its side.
