None existed actually, Earth and Space begin at pure POTENTIAL(situation) energy, but creatures on Planet Earth and the Solar System exist only at KINETIC(situation) energy of orbits and gravity of objects circling the Sun.
Therefore no scientists are able to build any machine to simulated creation of earth and space, until they travel out of Solar System, then only they can find a location of POTENTIAL areas for such scientist to machine and document a situation that could simulated the creation of earth and space.
They use centrifical force machines to duplicate high G-forces. They train underwater to simulate weightlessness.
Astronauts exercise in space to mitigate muscle and bone loss. They use special exercise equipment like treadmills, stationary bikes, and resistance machines to stay healthy during long-duration missions. These workouts help simulate the effects of weight-bearing activities on Earth.
Astronauts are trained to simulate various machines in space, primarily spacecraft systems and equipment used for conducting experiments. This includes training on life support systems, navigation controls, and robotic arms, as well as tools for maintenance and repairs. Additionally, they practice using scientific instruments for experiments and data collection. This training ensures they can effectively operate and troubleshoot equipment during missions.
yes
God created Heaven and Earth, including space.
The celestial equator is an imaginary circle created by extending Earth's equator into space. Zenith is an imaginary point in the sky directly above and observer on earth.
It is not yet known not only how, but whether or not space can be created or destroyed.
If you are Christian or Jewish you believe that God created man in his own image and created the Earth so his creation could have space to live.
1[ IS TO KILL DOGS 2] is to simulate outer space environment
Well, you'd need a vacuum chamber however large you need to simulate whatever you are doing. There is no other way, as air will make dust etc. billow instead of falling like gravel. And you would need to simulate low gravity. The only known way to do this is to be inside the so-called "vomit comet" plane, which can simulate low gravity for a few seconds at a time. Attempts to simulate low gravity with wire rigs simply don't work. The astronauts trained on such, but when they got to the Moon, found out that they needed to move differently than they thought, from the training. Really, there is no way to simulate the Moon, while on the Earth. Can you see moon hoaxers building a vacuum chamber seventeen miles long, to simulate the 17 miles the Rover traveled, transmitting camera and all? How do you simulate low gravity on something to large to fit in a Vomit Comet?
tons. there is even a space station
Freeze dried fruits and vegetables were first manufactured for consumption in space, but were later domesticated
