Christians - which wife with me in Heaven?

Asking for a friend…….

In Christianity, suppose my wife passes away.
We had always considered ourselves “soul mates” who would be reunited in heaven.

I meet someone else, fall in love, and marry wife number 2. My love for number 2 seems to be just as strong as wife number 1…..I consider her also to be my soul mate?

How is this resolved in Christian heaven? Who will I spend eternity with?

If transaction hashes only are stored in blocks, then where is OP_RETURN data stored?

An answer to a previous question and the whitepaper both agree that blocks don’t store full transactions, but rather, transaction hashes.

So then, what if I add data in OP_RETURN, say, the text “Hello, world!” Isn’t that a transaction output, or at least contained in an output, and therefore part of a transaction?

If not, or if so and only transaction hashes, not transactions themselves persist, then how does the OP_RETURN data stay on the blockchain?

Double hash in Bitcoin

what exactly is this? Does this mean every TX gets hashed twice? How does it help to filter the content from the block chain (As Dr. Wright said)? Why cant i hash it just once and save the hash of the TX and prune the data (illegal)? Isnt the content now filtered with just a single hash? or am i getting it wrong?

How can Bitcoin help us fight with Coronavirus?

We are looking for ideas about how could Bitcoin help us to fight the Coronavirus (or any future) pandemic.

Think about ways Bitcoin could help individuals through this, but also about how it could help health care systems to more efficiently cope with increased number of cases.

Provide examples of multi-sig scripts

What are the possible Bitcoin scripts to create a multi-sig transaction? Please provide the script code with explanations.

I would like to see at least two types of such scripts explained (OP_CHECKMULTISIG and the one with conditional OP_IF statements that Steve Shadders showed at this CoinGeek Seoul presentation). If there are more options, please list them as well.
