If someone were to find a Proof of Work collision, could they pin the tail of the tangle to the head?

If someone were to find a Transaction Proof of Work collision, would it be possible to pin the tail of the tangle to the head and create an infinite loop? IE. Create a self-referential tangle segment ...

Is it possible to create transactions that require less POW

The compute times for the proof-of-work varies considerably within a random sample of input data. With some input data, the POW can take 1/100th to even 1/1000th as little time as it takes normally (...

What does it mean that “the tangle is network-bound instead of hash-power-bound like blockchain”?

Can someone explain me in a very simple way what should an attacker do to double spend in IOTA? In the whitepaper I read that a double spend transaction should outweigh the legitimate subtangle. ...
