7/10, this is a story of a scholar who uses basic mathematics to find aliens. On the Kardashev level of civilization, Earth is far from even one level. The male protagonist's appearance and acting skills are not like...

If you like it, you will feel good, and if you don't like it, you will feel nothing. It is not a sci-fi film, nor can it be said to be a suspense film, it may be a reasoning...

Reason for praise 1. The theoretical definitions of interstellar civilization and exploration are the mainstream and realistic in the current world. 2. The handling of contradictions is also very real, such as microscopic aspects: scientists do not contribute to the earth and the outer space of the earth and think about alien civilizations all day long, which is really unrealistic. Macro aspects: taxpayers' money should not be used to find other civilizations, but to serve the society and the...

The budget for this film is estimated to be no more than a small three-bedroom. And it's more like an experimental film, a college graduation work, or a promotional film for ufo lovers and weird engineering men. As a movie, it is a pass, and there are no loopholes in its plot, actor performance, and scene scheduling. It is slow to the point of being out of the body, mediocre to the point of tasteless, and it cured my insomnia. Who sees who...

Aliens like to tease you
Came all the way to the earth, showed up and ran away.
I'm afraid you won't notice me, so I leave a radio wave for you to guess the riddle.

Professor Hendricks: Chapter four. Eigenvalues and Eigenvectors. Now, if we have a square matrix "A" that represents a linear transformation, then this matrix times the vector is equal to a scalar lambda times the same vector. Now, the "v" is called an eigenvector, and the lambda is called an eigenvalue, and these kinds of problems have applications in all kinds of things, like structural engineering, and spin transitions and neutral hydrogen.
Professor Hendricks: [after a pause] And it has a wavelength of 21 centimeters. That would be significant, wouldn't it? Derek?
Derek: It doesn't matter. The matrix is double, or half, or whatever.
Professor Hendricks: Twenty-one centimeters.
Derek: [confused] Twenty-one centimeters, what?
Professor Hendricks: The frequency of hydrogen. The spectral line of neutral hydrogen has a frequency of 1,420 MHz and a wavelength of 21 centimeters. Two lines, 38 increments east.
Derek: And 22 north.
Professor Hendricks: And then you multiply both by 9,433.
Derek: And then by 21 centimeters. The wavelength is the unit of the measurement. It is coordinates.

Prologue: Hydrogen atoms emit light at specific energy levels. These energies are determined by the Fine-Structure Constant. Fine-Structure Constant = 0.0072973525664 17. The FSC is a mysterious number that appears in many calculations of the most fundamental physics in our universe but we have no idea where it comes from. The atmosphere, the stars, the air we breathe, even our shoelaces have an atomic makeup that include this enigmatic number. It is a mathematical concept that would be recognized anywhere in the universe. In 1974 Frank, Carl Sagan and several others scientists sent the Arecibo Message into space. It contained basic math and other information intented to establish contact with other life in the universe. They aimed at at the star cluster M13, and the world waited in anticipation for a response bit it would take 22,800 years for the message to reach someone in M13 unless they come to us first.
