The Titanic could carry 3,547 people in speed and comfort, [3] and was built on an unprecedented scale. Her reciprocating engines were the largest that had ever been built, standing 40 feet (12 m) high and with cylinders 9 feet (2.7 m) in diameter, requiring the burning of 600 long tons (610 t) of coal per day.
Titanic was 882 feet 9 inches (269.06 m) long with a maximum breadth of 92 feet 6 inches (28.19 m). The ship's total height, measured from the base of the keel to the top of the bridge, was 104 feet (32 m). [16] Titanic measured 46,329 GRT and 21,831 NRT [17] and with a draught of 34 feet 7 inches (10.54 m) and displaced 52,310 tonnes. [5]
In the Revelation Space series by Alastair Reynolds, interstellar commerce depends upon "lighthugger" starships which can accelerate indefinitely at 1 g, with superseded antimatter powered constant acceleration drives. The effects of relativistic travel are an important plot point in several stories, informing the psychologies and politics of ...
When I was there, I think there were—if memory serves—five or six submersibles in the world that could go down deep enough to get to the Titanic. The Nautile submersible. Pool IFREMER/MAIOFISS ...
Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67 × 10 −11 m 3 ⋅kg −1 ⋅s −2 [4])
At Titanic depths, some 12,500 feet down, the water pressure is nearly 400 times more than at the ocean's surface — some 6,000 pounds would have been pressing down on every square inch of Titan ...
“The deeper you go into the ocean, the less knowledgeable we are,” marine biologist Dr Steve Ross, who was on the same submersible as Ms Rojas, said before the 2022 expedition.
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
