Solid black lines: Well calibrated ladder step. Dashed black lines: Uncertain calibration ladder step. The cosmic distance ladder (also known as the extragalactic distance scale ) is the succession of methods by which astronomers determine the distances to celestial objects.
Nuclear fusion reaction of two helium-4 nuclei produces beryllium-8, which is highly unstable, and decays back into smaller nuclei with a half-life of 8.19 × 10 −17 s, unless within that time a third alpha particle fuses with the beryllium-8 nucleus [3] to produce an excited resonance state of carbon-12, [4] called the Hoyle state, which ...
La La La Human Steps was a Québécois contemporary dance group in Canada, active between 1980 and 2015, known for its energetic, acrobatic style involving fast-paced and athletic physical contact. Its signature move was the barrel jump – a gravity-defying, fully horizontal, mid-air barrel roll .

A list of future observable astronomical events. [1] These are by no means all events, but only the notable or rare ones. In particular, it does not include solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these).
Human flag on a diagonal ladder Overhand grip human flag on a pole Human flag using a tree. The human flag (known as an iron X in pole dancing) [1] is a feat of strength where the body is parallel to the ground supported by a vertical bar. A straight line is formed using the arms and body.
An anti-cat/rabbit cat protestor is chased by a large rabbit and barges into the music club where Pi's band is performing. When the rabbit grabs and punches him in front of the crowd, Pi gets offstage to rebuke the attacker, but stops when she sees the entire club showing her the pro-cat/rabbit symbol on their phones.
Stellar engineering is a type of engineering (currently a form of exploratory engineering) concerned with creating or modifying stars through artificial means.. While humanity does not yet possess the technological ability to perform stellar engineering of any kind, stellar manipulation (or husbandry), requiring substantially less technological advancement than would be needed to create a new ...
