資料（サンプル）を電子線が通過して 数秒後の　いまを　ｔ＝０と　設定する 話を簡単にする為に 物理的には　有り得ない設定を加える

2022zionad @2022zionad

The document (sample) is subjected to electron beams, nd we set the moment a few seconds later as t = 0. To simplify the discussion, we introduce settings that are physically impossible.

電子線が　通過してもサンプルは 宇宙空間内で　不動を続ける

2022zionad @2022zionad

Even though the electron beams pass through, the sample remains motionless in outer space.

電子線が　サンプルを通過した瞬間 架空設定の　事象情報 拡散線が その位置を中心に 理想状態の光速C 100%速度で 事象情報 拡散線が進む

2022zionad @2022zionad

The moment the electron beams pass through the sample, in the hypothetical scenario, event information diffusion rays propagate from that position. In the ideal state, these event information diffusion rays advance at 100% of the ideal speed of light (C).

３６０度方向に　無数の 「事象情報 拡散線」が進み その先端複数が　同心円を描く ここではｘｙ平面だけで　考える

2022zionad @2022zionad

Countless "event information diffusion rays" propagate in a 360-degree direction, with multiple endpoints tracing concentric circles in the xy-plane.

電子物体の位置と 電子線がサンプルを通過した位置の 中間位置を　 ｘｙ平面　原点O（０，０）に 固定し続ける 凝視（ぎょうし）し続ける座標系を使ってるが

2022zionad @2022zionad

The intermediate position between the location of the electron object and the position where the electron beams pass through the sample is fixed at the origin O (0, 0) in the xy-plane. This is done using a coordinate system that continues to focus and observe.

資料（サンプル）は　リアル宇宙内で　不動設定 電子物体は　リアル宇宙内で　 速度変更は　V=０から　V=C(光速C）の 範囲内だけ

2022zionad @2022zionad

The document (sample) is set to be stationary in real outer space. The electron object is also within real outer space, and its velocity can vary within the range of V = 0 to V = C(the speed of light, C).

2022zionad @2022zionad

この座標系では 電子物体と 資料（サンプル）の速度は 同じ速度で描画しているが ２つの存在位置の 中間位置に注目することで １つの系として扱える これは便利であるけれど 恣意的であることも　意識する

2022zionad @2022zionad

In this coordinate system, the velocities of the electron object and the sample are depicted　as the same, considering the midpoint between their respective positions.

2022zionad @2022zionad

This allows treating them as a single system, which is convenient but should be acknowledged as an arbitrary choice.

リアル宇宙内で　不動状態を続けてる サンプル塊（かたまり）に 電子物体の動く速度を 光速C　とし 100%の相対速度に　設定する

2022zionad @2022zionad

The sample mass (clump) remains stationary in real outer space. The velocity of the electron object, in relation to the sample, is set to the speed of light C, resulting in a relative velocity of 100%.

2022zionad @2022zionad

しかし　この座標系では 電子物体は 光速Cの50%で 動いているように　描画されいる 見かけ速度　光速Cの　半分速度

2022zionad @2022zionad

However, in this coordinate system, the electron object appears to be moving at 50% of the speed of light C. This is the apparent velocity within this reference frame.

2022zionad @2022zionad

リアル宇宙空間の　すべての点が この座標系では　光速Cの50%で 右に動いているように　 描画される

2022zionad @2022zionad

In this coordinate system, every point in real outer space appears to be moving to the right at 50% of the speed of light C. This is an apparent representation within this specific reference frame.
