The experiment of the Japanese astronaut started by throwing a boomerang in space and ended by proving that even in space a boomerang flies back just like it does on Earth
The Japan Space Agency reports that Japanese astronaut Taku Doi conducted an experiment on the International Space Station during his free hour on March 18, 2008 and got unexpected results. It turns out that when you throw a boomerang in space, it bounces back just like it does on Earth.
The experiment was carried out following the request of Yasuhiro Togai, the world champion in boomerang throwing, who is also Japanese. Togai wanted to check if the rules on Earth also apply in space.
This simple experiment surprised many, including the astronaut who performed it. Following the great interest, the space agency announced that it would later release a tape that recorded the experiment. Many will argue that the experiment has no scientific value, but it turns out that there is great interest from researchers in the field of aviation and aerodynamics.
Japanese astronaut Taku Doi arrived at the International Space Station on March 11 aboard the Space Shuttle Endeavor carrying the first part of Japan's Kibu Space Laboratory.

If the experiment works in a vacuum it will be a surprise, but why would such a thing entail the existence of additional dimensions?
I don't agree with you.

The third dimension
If the experiment will also work in a vacuum, it is a discovery of another dimension.
This is not the fifth dimension but the sixth.
Since we are about 4 dimensions inside the fifth dimension.
In my opinion there is no chance, because you cannot skip dimensions but go through them.
Thanks to Mahula
a quote:
the experiment on board the ISS was a design of Broadbent's called a "Roomerang," a small, tri-blade boomerang intended for use indoors in a small area or outdoors in light winds. It travels 5 to 8 feet before returning to the thrower
That is, it is a small boomerang with three arms built to return to the sender after 1.5-2.5 meters. And the experiment was done inside the space station.
may we have a nice week.

It's not open space and it's not a regular boomerang.

As we have already concluded - this could not happen in a vacuum. Therefore it happened in an area with some gas. Gases transmit sound and that's why we heard.
Have you heard about the Australian who bought a new boomerang but couldn't get rid of the old one?!
Well, commenter Yaniv cool, dear, you were wrong, you were also wrong.
I will start with the difference, I sent the response in question dated 28.3.08/13.07/XNUMX at XNUMX:XNUMX PM not from my private home, but from the home of my dear friend Eliezer. I thought to Tommy that in my understanding, in wonderful ways, you were able to discover this and put forward your hypothesis, which may make sense.
However, as soon as you didn't mention this in your last comment and went into the lines of a psychological analysis (interesting, I must say) of the writer's personality, then you failed and even lied.
And about the surgery itself
The arrogance you see in me was done very humbly because I only claim about "cosmological progress" and not "scientific progress" at all. Any sane person would understand that there is at least a hint of modesty in this.
You claim that Ami Bachar was hurt by my reaction, and perhaps there is some truth in that because he only reacted with one smiley and not a series - as was requested. So I apologize from the bottom of my heart for hurting my old friend Ami Bachar.
But I won't give up on one thing!, I'm not ready for you to accuse me of cynically exploiting great scientists such as Galileo. It's the least they can do for a commenter on the science website in one of his difficult hours.
I hope that now a cool commenter will yield, you will finally, finally, agree to unite my split personality, which you split with vain claims, and thank you that they are one!
Have a united weekend
only with a smile

To the fake Yehuda Sabdarmish and the original Yehuda Sabdarmish,
"Your despicable attempt, by any standard, to prevent the future of cosmological progress with the help of my blessed theory causes sad thoughts in all self-respecting science commenters."
The original Yehuda Sabdarmish was not exaggerating and arrogant with his theory. The original Yehuda Sabdarmish maintains modesty and is not arrogant.
"Your cynical exploitation of my carelessly made mistake deserves only to be tolerated."
The original Yehuda Sabdarmish recognizes a sense of humor and would not be offended by what Ami Bachar wrote in jest. The original Yehuda Sabdarmish does not use the words of psychometrics.
"In moments like these, I feel very well the feeling of my old friend, who today I often quote, Galileo, peace be upon him, who cried: "And yet they will move, they will move (the particles)""
The original Yehuda Sabdarmish did not rape great scientists who died a long time ago and exploit them cynically for his needs and the needs of his theory.
"Hello
Sabdarmish Yehuda"
The original Yuval usually writes welcoming, happy and hopeful endings to his messages.
"P.S. If anything, I wonder if spiral galaxies have boomerang properties that would cause the galaxies to eventually bounce back from their accelerated escape?"
The original Yehuda Sabdarmish doesn't write nonsense..
With thanks and best regards,
The cool Yaniv
Ahh
Sorry.. the cool commenter!!
Mr. responds coolly
I'm sorry, but the one above you is Yehuda Sabdarmish and it's not an imitation. But I wonder why you decided it was an imitation because there is still one difference between my reaction to this and the others?
???????????????
Have a good evening
Sabdarmish Yehuda
Yehuda, congratulations on your chivalrous spirit and sense of humor!
😀
The one above me is not Yehuda.. but a great imitation
To Ami Bachar

In moments like these, I feel very well the feeling of my old friend, whom today I often quote, Galileo, peace be upon him, who cried: "And yet they will move, they will move (the particles)"
Hello
Sabdarmish Yehuda
post Scriptum. If anything, I wonder if spiral galaxies have boomerang properties that will cause the galaxies to eventually bounce back from their accelerated escape?
I think the most important thing that came out of this letter is a one-time, primary and uncompromising document of Sabdarmish Yehuda, which refers to the empty space. "Empty space" says Yehuda, thereby demolishing his great theory regarding the movement of the universe in one fell swoop.
: )
Shabbat Shalom to all

When I read the title before entering the article I was really very surprised.
I didn't understand how a boomerang could work without air.
When I opened the article it seemed a little more logical to me because I saw two things:
1. That the experiment was carried out on the space station
2. That the experiment was carried out during the astronaut's free time
The fact that it says "in the space station" implies that it is probably not outside of it but I still wasn't sure and I asked myself exactly what Yehuda asked himself but the fact that it was done in his free time cleared things up for me. It is impossible to perform a spacewalk during free time, on the one hand, and certainly there is no special device for throwing a boomerang on the outside of the station.
Therefore, what is misleading here is, in my opinion, the title because when you write the space, you usually mean the "empty space" and not a space full of air.
If the experiment was indeed carried out inside the station, I accept Aryeh Seter's opinion.
It is true that if it didn't work there I would try to find the explanation for it in the absence of gravity but my initial guess was that it would work because what is special about the boomerang on Earth is the fact that it returns and not the fact that it flies this or that distance without falling. Also the fact that the boomerang works independently of the angle of its launch relative to the horizon suggests that its special movement is derived only from aerodynamic phenomena.
In my opinion the experiment was conducted in space, because otherwise it has no meaning. And if he was held in space, it is impossible for him to have behaved in this way. The most puzzling thing.
Boomerang and intentions to launch an origami plane in space and I think the next step will be to project anime movies on the moon so that it has big, sparkling eyes. Indeed a country with flight in the field of research.
If the knowledge system could attach a link or a built-in video clip of the boomerang throw, I would be very grateful
Boomerang flies tens of meters away. It doesn't seem to me that the space station has such a large space for such an experiment.
Waiting for the tape to see what mini-experiment he did there.
In the empty space it probably wouldn't work.
Have a good weekend

The boomerang works according to aerodynamic principles, so there was no reason to think that it would not work in the air inside a spaceship. The authors of the news should have gone ahead and explained why it is not so obvious that the boomerang will operate in the spaceship's air. If they asked me - I would say that it will work. Just a PR news from the Japanese space agency, without scientific value.
He conducted the experiment inside the space station where there is air - so what is implied is that the boomerang does not depend on gravity but on air resistance
Apparently, until the current experiment, this was not obvious because many people were surprised by its results.
The behavior of the boomerang in space seems obvious to me [similar to a gyroscope]
