one of these address start with "s-" but regular bitcoin address start with "1","3" or "bc1" :

That is not a bitcoin address and there is no string to start with a letter such as "s-" associated with that script. This particular block explorer called blockchair has its own undocumented way of assigning a seemingly random string that usually start with a letter like "s" to any output script that it doesn't recognize. This is not universal standard and we don't even know how the conversion takes place (it is undocumented).

Largest transaction in bitcoin : 500,000.00 BTC sent in 2011 !

Normally we report the total input amounts as the value size of a transaction not a single output it creates. The total value is 550k.

Block 478558 was the last block Bitcoin and BitcoinCash had in common, so block #478559 are different :

This is more of a bcash fun fact not bitcoin's. Specially since bcash was neither the first nor the last shitcoin that copied bitcoin's code and blockchain. There were others before it and a lot after it.

Just after BTC big fork, a miner wrote "FUCK BITCOIN CASH" on a block :

Funny but I'd say it is still a bcash fun fact
