スティーブン・ホーキングのブラックホールとダークマターに関する理論は却下された (Stephen Hawking theory about black holes and dark matter is RULED OUT)
- But observations show that most stars have a similar orbit speed around their galactic disk, however close or far out they are, which implies that there is some gravitational force at work that we can't see and so far don't understand.
重力の法則からすると、銀河系の外側にある星は、例えば惑星のように速く回転するはずの中心に近い星よりも、銀河系の周りをゆっくり回転しているように見えるはずだ。
- But observations show that most stars have a similar orbit speed around their galactic disk, however close or far out they are, which implies that there is some gravitational force at work that we can't see and so far don't understand.
しかし、観測によれば、ほとんどの星は銀河系円盤の周りを、どんなに近くても遠くても、同じような軌道速度で回っている。

- Stephen Hawking explained it like this, two pieces of matter that are close to each other have less positive energy than the same two pieces a long way apart, because you have to expend energy to separate them against the gravitational force that is pulling them together.
スティーブン・ホーキング博士はこのように説明した。2つの物質が互いに接近している場合、同じ2つの物質が遠く離れている場合よりも正のエネルギーが小さくなる。
- Stephen Hawking explained it like this: two pieces of matter that are close to each other have less positive energy than the same two pieces a long way apart, because you have to expend energy to separate them against the gravitational force that is pulling them together.
2つの物質を分離するにはプラスのエネルギーが必要なので、重力は2つを引き寄せるためにマイナスのエネルギーを使っているはずだ。
月は惑星だという主張！ (An Argument The Moon is a PLANET!)
- In fact, as I've explored in a previous video, the gravitational force from the Sun on the Moon is twice as much as the force from the Earth,
まず最初の基準から始めます。
- In fact, as I've explored in a previous video, the gravitational force from the sun on the Moon is twice as much as the force from the Earth.
実は、以前の動画でも触れましたが、太陽から月にかかる重力は地球からかかる重力の2倍もあるんです。
アインシュタインがいなくても一般相対性理論は発見されたのか | ショーン・キャロル (Why general relativity would’ve been discovered without Einstein | Sean Carroll)
- Newton posited that if you have two objects with two different masses, they have a gravitational force that will pull them together that diminishes as 1 over the square of the distance between them.
それは物理学の枠組みの根本的な再構築でした。
- They have a gravitational force that will pull them together that diminishes as one over the square of the distance between them.
それらの間には、物体間の距離の二乗に反比例して弱まる重力が働き、それらを互いに引きつけます。
