Once apon a time, there was nothing

The story of the Universe and everything.

宇宙とその他諸々の物語narrated by Laila Alabidi

and that nothing was bountiful ...「無」は豊富にあった ...

The Universe as weknew it

how things have changed!宇宙は徐々に大きさを増していると考えられ

...but where did all this stuff come from?

and why did the Universe go bang?すべてのものはどこから来たのか?

なぜ宇宙は爆発したのか?

Page 5: Story of the Universe

to answer those questions, to a man called Heisenberg we must turn, for he had declared: “uncertainty is our guiding

principle!”ハイゼンバーグ:

「わからない」ことが結果につながる

Page 6: Story of the Universe

ENEGRY-anti thing=thingエネルギー−反物質=物質

the science of uncertainty不確実の科学

thing + anti thing=ENERGY物質+反物質=エネルギー

ENEGRY-anti thing=thingエネルギー−反物質=物質

Page 7: Story of the Universe

we get blips of stuff and anti-stuff, so

what! we said.

物質と反物質... それがどう

したの?

so Inflation! said a young man called

Guth.だからインフレーションだ!とグースは言った。

“Anyone who is not shocked by quantum mechanic

has not fully understood it”Neils Bohr,

the father of Quantum Mechanics

「量子力学にショックを受けない人は、理解が足りない」ニール・ボア 量子力学の父

Page 10: Story of the Universe

Are things getting more confusing?

余計わからない?

is inflation magic? we wanted to know!インフレーションは魔法?

no said the particle physicists, it is an exotic particle!

素粒子物理学者は、魔法ではなくエキゾチック粒子だと言いました。

Page 11: Story of the Universe

Air is “normal”positive pressure

空気は「正常の」圧力

Page 12: Story of the Universe

Inflation sucked some anti things out

we now have things and some energy物質とエネルギーがあって

and then BLAP: the whole Universe o_0それが爆発して宇宙ができあがった ...

Nice story... but how do you know it is true?それが本当だとどうしてわかる?

is she lying?

Evidence that the Universe started off with a blip.証拠は私たちの身の周りに存在します。

Page 17: Story of the Universe

but, Quantum mechanics says thatnothing cannot exist

だが、量子力学は、無は存在しないと説く

we used to think that somethingcame from nothing

物事は無の状態から生まれると考えられていた

there is always something, or the potential for something...

いつどこにでも、何かが、または何かが生まれるための可能性が存在する ...

and that something could lead to everything...そして、それらはすべてにつながっている ...

Page 18: Story of the Universe

Are these “quantum fluctuations” even real?「量子的ゆらぎ」は本当にあるのか?

or do scientists just have a great imagination?それとも、科学者たちは想像力が豊かなだけ?

you may be wondering ...

Page 19: Story of the Universe

well, that’s a story for another day ...それは、またの機会に!

Page 20: Story of the Universe

“Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not

really there, but just to comprehend those thingswhich are there”,

我々は想像力を最大限に使うことができる。ただ、それはフィクションのように存在しないものを想像するためではなく、そ

こにあるものを理解するために必要なのだ。Richard Feynman, theoretical physicist, 1918--1988

リチャード・ファインマン 物理学者

and so our story must end, with a quote froma clever man:

THE END

ありがとう!Special thanks to **Akira Sasabe**

for the wonderful transalation!
