2. Because the technology will be brilliant in 4004, the spaceships will fly faster than the light. [Is it O.K. to use "Because" at the beginning of the sentence?]

Hi,
Just a quick note. My understanding is that question tags are the opposite of the statement.

You don´t eat children, do you?

Negative statement -positive tag.

He has some apples, hasn´t he?

Positive statement-negative tag.

Lola hasn´t any time, has she?
OR
Lola has no time, has she?
OR you could go with 'do'
