Let's forget the nonsensicals and get back on track? B-)

Now at the time of the Big Bang, "stuff" had no mass (?) but then "they" conveniently bend the Laws of Physics/Motion/Mass/Energy and any "Laws" you care to invent and say that "stuff" (with no mass, remember?) "expanded" faster than the speed of light?

Soooo, as there was "nothing" to slow it down (an object, when propelled by a force will continue in the direction of that force until acted upon by another force) why did it not continue at that speed?

There was no mass to slow it down therefore there was no gravity? To have gravity "things" must have mass?

Somehow "stuff" with no mass acquired mass from somewhere? Ah-ha, the Dark Matter? I just knew Dark Matter would have to get in on the act?

Oh, perhaps it was the Dark Energy that slowed everything down?

Maybe Dark Matter was "out there" all along, it wasn't created by the Big Bang?

Blimey, it's all too much, I must take a rest for now.
