空间 (物理)

Multi tool use

本條目介紹的是距離與方向的廣義架構。關於地球大氣層以外的空間,請見“
太空”。關於其他相似名詞,請見“
空間 (消歧義)”。
空间為一種抽象觀念,乃是物質與事件存在並有彼此相對關係的客观形式。与“时间”相对,通常指四方上下。
古典物理的解释:宇宙中物质实体之外的部分称为空间。近代物理的解释:宇宙物质实体运动所发生的部分称为空间。在相對論中,時間與空間一起組成四維時空,構成宇宙的基本結構。

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
