Description

Technical Field

[0001] The utility model relates to the technical field of astronomical science popularization, in particular to a black hole interactive demonstrator. Background Art

[0002] A black hole is an extremely special and mysterious celestial body. Its definition and characteristics are mainly based on the theories of modern astronomy and general relativity. A black hole is a star that has evolved to its final stage, formed by the further contraction of a neutron star. It has a huge gravitational field, which makes it impossible for any electromagnetic waves emitted by it to propagate outward, turning it into an invisible isolated celestial body. People can only determine its existence through gravitational effects, hence the name black hole.

[0003] Most teenagers can only acquire relevant knowledge about black holes through videos or pictures, and there is no device on the market that can demonstrate the gravity of black holes more intuitively, which results in teenagers being unable to understand the professional knowledge about black holes more clearly; so we proposed a black hole interactive demonstrator to solve the above problems.
