After radioactive decay was discovered, it was realized it would release heat inside the planet. This undermines the cooling effect upon which the shrinking planet theory is based. [4] Identical fossils have been found thousands of kilometres apart, showing the planet was once a single continent which broke apart because of plate tectonics.
Air bubbles and particles trapped inside the ice could also reveal why the planet’s ice ages suddenly became longer and more intense about 1 million years ago, which may have caused ancient ...
Scientists are unsure what is causing subtle speeding up of Red Planet’s rotation – but they have some ideas Length of a day on Mars is shrinking as planet is strangely spinning faster every ...
Gravitational collapse of a massive star, resulting in a Type II supernova. Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity. [1]
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
The shrink ray turns out to be faulty, however, as shrunken items return to normal size after a period of time. A shrink ray is a recurring device shown in Venture Brothers, although it never seems to actually work properly. In Despicable Me, Gru used a shrink ray to shrink the Moon and pocket it. The effects of the shrink ray are only ...
