In addition, the invention also discloses a celestial body operation simulation method adopting the celestial body operation simulation device, which is used for simulating the gravitational force and the celestial body revolution, and specifically comprises the following steps:
s11, the sphere is an attraction simulation sphere, and comprises: a first sphere and a second sphere, the mass of the first sphere being greater than the mass of the second sphere;
s12, placing the first sphere on the elastic film, wherein the first sphere forces the elastic film to be sunken;

Further, the mass of the first sphere is related to the elasticity of the elastic film, the first sphere is placed on the elastic film, a horn-shaped slope is formed after the elastic film is sunken, and the slope of the slope is 10-100%.
In addition, the invention also discloses a celestial body operation simulation method adopting the celestial body operation simulation device, which is used for simulating dark substances and specifically comprises the following steps:
s21, the ball body is a dark matter simulation ball, and the color of the dark matter simulation ball is consistent with that of the elastic film;

s22, placing a plurality of dark matter simulation balls on the elastic film, when the collected dark matter simulation balls reach a certain number, the elastic film is concavely deformed, so that universal gravitation which is invisible to naked eyes but is generated when a large number of dark matter simulation balls are collected together is simulated, and light and gravitation dark matter can be changed.
Dark matter is matter that is actually present in the universe but is not responsive to electromagnetic waves, so that an electromagnetic wave detector, including the human eye, cannot see it, but when a large amount of dark matter is gathered together, the gravitational force generated can change light and gravitational force, and scientists infer its presence from this.
The dark matter is simulated by a large number of light pellets with the same color as the elastic film, the light is dimmed, one light pellet is placed on the elastic film, the existence of the light pellet on the elastic film is difficult to be seen by an observer due to the identical color, and the existence of the light pellet cannot be estimated by the observer due to the deformation of the elastic film even caused by a small number of light pellets due to the light weight of the light pellet. Only when a large number of light pellets are gathered, the observer cannot see clear light pellets, but can infer the presence of light pellets by deformation of the surface of the elastic membrane, i.e., by changes in attractive force that we simulate.

If there is no dark energy, the universe should collapse under the force of gravity. Positive pressure gas blown into the tub by the blower can be understood as dark energy. After turning off the blower, a large number of spheres were put on the elastic film, and it was observed that the spheres representing celestial bodies eventually converged together to form a cluster. This is a model that simulates what would eventually collapse in the absence of dark energy.
The dark energy is basically and evenly distributed in the universe, so that the universe expansion is promoted, namely the negative pressure characteristic of the universe expansion can be perfectly displayed by using a blower. The blower was turned on to adjust to the proper strength, and a large number of spheres were again thrown in, and it was observed that the spheres rolled off the edge of the elastic film. And initially the heavy roll-off is a light-weight pellet to simulate dark matter, similar to what current research has found dark energy is causing dark matter to disappear. Then the distance between the spheres of all simulated celestial bodies is increased, the increasing speed is faster and faster, and finally all spheres roll off the edge of the elastic film, so that the expansion of universe under the action of dark energy is simulated, and the expansion speed is faster and faster.

Two strong magnetic steel balls are used for simulating two neutron stars or black holes, and an observer lightly places hands at the edge of the elastic film to feel vibration of the elastic film.
When two spheres collide and are adsorbed together in the movement of the elastic film surface, the moment shock wave felt by the hands of the observer is the simulated gravitational wave, and the shock wave completely accords with the characteristic of very short duration of the gravitational wave.

The celestial body operation simulation method according to claim 5, wherein the sphere in step S32 includes a plurality of heavy spheres for simulating the revolution of a planet, the heavy spheres gradually increase in revolution radius with the gradual swelling of the elastic film, the revolution speed gradually increases until the heavy spheres roll out of the elastic film, and the spheres are further used for simulating the expansion of the universe under the action of dark energy, and the expansion speed is increasingly faster.
7. The celestial body operation simulation method adopting the celestial body operation simulation device is characterized in that the celestial body operation simulation device comprises: a barrel, an elastic film, a blower, and at least two spheres; the elastic film covers the upper opening edge of the barrel-shaped body; the sphere is placed on the elastic film for simulating celestial bodies or dark substances; the elastic film is densely provided with air holes; the air blower is communicated with the inner space of the barrel-shaped body through an air inlet pipeline and is used for blowing air into the barrel-shaped body and forming positive pressure, and the air in the barrel-shaped body is discharged from the air hole and is used for bearing part of gravity of the ball body; the pore size of the air hole is 0.03-1mm; the elastic film is a rubber film, a silica gel film, a polyolefin film, a polyester film or a polyurethane film; the celestial body operation simulation method is used for simulating gravitational waves and specifically comprises the following steps of:
s41, the ball body is a magnetic ball;
s42, placing two magnetic balls on the elastic film at intervals, and running according to respective tracks;
under the action of magnetic force, the two magnetic balls are close to each other and finally collide and are adsorbed together, shock waves generated during collision are transmitted outwards through the elastic film, and an observer can feel the shock waves when placing hands on the edge of the elastic film.
