Could ringworld be possible?
To get Earth-like gravity, the Ringworld would need to spin at nearly three million miles per hour. Very fast, to be sure. But in a frictionless space environment, it could be doable. The ring could work up to that speed over time and then maintain it with little additional thrusting.
How high are the ringworld walls?
Ringworld parameters
| Radius | 9.5×107 miles (~1.5×108 km) (~1 AU) |
|---|---|
| Circumference | 6×108 miles (~9.7×108 km) |
| Width | 997,000 miles (1,600,000 km) |
| Height of rim walls | 1,000 miles (1,600 km) |
| Mass | 2×1027 kg (1.8×1024 short tons) (1,250,000 kg/m², e.g. 250 m thick, 5,000 kg/m³) |
Why it should hold an atmosphere?
The atmosphere is made of gases that are essential for photosynthesis and other life activities. The atmosphere is a crucial part of the water cycle. It is an important reservoir for water, and the source of precipitation. The atmosphere moderates Earth’s temperature.
What if we built a Ringworld in space?
We might have to sacrifice all the planets, moons and asteroids in the Solar System. Our ringworld would be left all alone in the entire Solar System. If we could manage to gather and transport all the material available, then construction would begin.
What is the plot of Ringworld?
Ringworld tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space 186 million miles (299 million kilometres) in diameter.
What is the important of the atmosphere?
The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle.
What holds Earth’s atmosphere in place?
Gravity
Gravity. Fortunately for us, Earth’s gravity is strong enough to hold onto its atmosphere. Mars, for example, is less than half Earth’s size and around one-tenth Earth’s mass. Less mass means less gravitational pull.
How fast does a Ringworld spin?
approximately 1,200,000mph
Assuming that the ringworld shares the same diameter as that of the Earth’s orbit (about 186 million miles, or 300 million km on average), and required approximately 1G of gravity, the ringworld would need to rotate at approximately 1,200,000mph.
How big is a Ringworld?
about one million miles
The Ringworld is about one million miles (1.6 million km) wide and approximately the diameter of Earth’s orbit (which makes it about 584.3 million miles or 940.4 million km in circumference), encircling a sunlike star.
