Do you have unique friends?

Ingenious friends are interesting, aren't they?

I can get used to it once in a while.

in Japan! December 4th is E.T.s' day.

It was decided on December 4, 1982 to commemorate the release of Steven Spielberg's masterpiece "E.T." in Japan.

Although it is not an official anniversary, various events were held before the COVID-19 epidemic.

Prior to this movie, space visitors were mostly hostile stories.

Steven Spielberg's work depicts cross-cultural exchange with aliens even in " Close Encounters of the Third Kind".

It is a work that expands the possibilities of dreams for space.

Speaking of space topics, do you know about the black hole officially announced on November 30th?

There are two supermassive black holes in the galaxy NGC7727, 89 million light-years away from Earth in the direction of Aquarius.

89 million years light-years is the distance required for 89 million years at the speed of light, but it is a very neighborhood place in terms of astronomical distance.

The black holes in this pair are binary stars, with the larger black hole having a mass of 154 million times that of the Sun and the smaller black hole having a mass of 6.3 million times that of the Sun.

The distance between the two black holes is 16 million light-years, and each other's supergravity acts to merge them into one monster black hole within 250 million years.

The impact on the Earth after becoming a super black hole is still unknown, but it is doubtful whether life will exist on the Earth 250 million years later.

There is a high possibility that humankind has been extinct, and the existence of the planet Earth itself is unknown.

Therefore, it is more important to dream about the future of your own life and live today with a vision, rather than worrying about the far future.
