Wormholes, bridges, and more: The science behind Stranger Things season 5
Stranger Things Season 5 reinterprets the Upside Down as a wormhole, a theoretical spacetime bridge. While real wormholes face stability and energy challenges, science fiction, including this show, uses them for narrative convenience, enabling faster-than-light travel and interdimensional connections. This concept, rooted in Einstein's theories, allows for dramatic storytelling about reality's fragility.
Scientists have engineered an artificial womb lining, a breakthrough allowing unprecedented observation of early human embryo implantation. This innovative model mimics the uterine environment, enabling researchers to study the crucial 'chatter' between embryos and the lining. Understanding these interactions is key to unraveling implantation failures and improving pregnancy success rates.
Asteroid Apophis will make a historic close approach to Earth on April 13, 2029, passing within 32,000 kilometers. While initial fears of a collision were widespread, years of observation and simulations have confirmed Apophis poses no threat for at least a century. This harmless encounter offers a unique scientific opportunity to study the asteroid in unprecedented detail.
Will Earth really switch to 25 hours days as its rotation slowing down
Earth's days are slowly getting longer. This change is driven by the Moon's gravity and shifts in Earth's mass due to melting ice and rising seas. Scientists use advanced tools to measure these tiny shifts. A 25-hour day is a distant future event, taking millions of years. The current changes are imperceptible.
Get ready for a celestial spectacle in 2026! Witness a 'ring of fire' solar eclipse, a deep red lunar eclipse, and a rare Blue Moon. The year culminates with a spectacular total solar eclipse paired with the Perseid meteor shower, plus a supermoon on Christmas Eve. Don't miss NASA's Artemis II lunar mission!
How far have Earths radio signals really travelled into space
Earth's radio bubble, a century-old expansion of broadcast signals, now spans over 119 light-years. While these waves have reached nearby stars like Proxima Centauri, they are too faint and blended with cosmic noise for any civilization to decipher. Modern communication methods are also reducing the energy leaked into space, making Earth quieter.
NASA's Hubble Telescope has revealed that planetary systems experience violent collisions for much longer than previously thought. Observations of the Fomalhaut system, 25 light-years away, show recent, massive impacts between planetesimals, challenging existing models of planetary formation and dynamics. These events, once believed to be rare, are now seen as crucial for shaping planetary development.
Why this Indian river turns red during the monsoon
India's rivers transform annually during the monsoon season. Heavy rainfall increases river flow, stirring up sediment. Iron-rich soil particles are carried into the water, giving it a red hue. This natural process is linked to climate and geographical features. The intensity of the monsoon directly impacts the river's color. This annual event highlights India's dynamic natural cycles.
From foot to head: How Chinese doctors kept a severed ear alive; reattached it months later
In a remarkable feat of reconstructive surgery, Chinese doctors successfully grafted a woman's severed ear onto her foot to preserve it. After a severe workplace accident, the ear was reattached to her head following extensive scalp reconstruction. This innovative procedure highlights China's history of pioneering, unconventional medical interventions for severe injuries.
Did humans domesticate wolves 5000 years ago? Scientists find supporting evidence
Ancient wolf remains unearthed on a Baltic island suggest a complex relationship with humans 5,000 years ago. These wolves, brought to the island by people, shared diets and showed signs of care, hinting at a bond beyond mere coexistence. Genetic analysis reveals they weren't ancestors of modern dogs, raising new questions about early human-canid interactions.
What is the colour of water, and why does it look clear in a glass but blue in the sea
Water's colour, often unseen in small amounts, reveals itself in larger bodies like the sea. Scientists explain that water absorbs red light more than blue, a phenomenon noticeable only with significant depth. Particles, algae, and even sky reflection further influence the hues we perceive, turning clear water into a vibrant spectacle.
A hidden Arctic world: Methane mounds and life found 3.6 km below the Greenland Sea
Scientists have found a unique geological and biological complex deep in the Greenland Sea. Methane hydrate mounds, formed by trapped methane and ice, were discovered along the Molloy Ridge. These mounds support chemosynthetic organisms, life that thrives without sunlight. This discovery offers new insights into Arctic oceanography and methane stability.
