How is this possible?

How are these figures different? If light is the fastest speed possible, then how is the universe longer in distance, and light would be able to travel through it, or more specifically, in radius? Due to the BB.

Because photons travel within the medium that is 'Space time'.
There is nothing within our undrestanding of reailty that says space time itself cannot undergo chages.
Hence the fabric of reality is (Potenetially) 'Expanding' faster than the photons moving through it.

TBH it took me a while to accept that the expansion of the universe could be faster than the speed of light. That really bugged the hell out of me for a long time. But, it also took me a long time to accept that color was in light not in the object/life itself.

Take a laser pointer, point it at the Moon and wave it like crazy across the moon. You will (possibly, just if you wiggle hard enough) see a laser dot moving with a speed >c.

I saw a great tik-tok explaining this but I doubt I will find it again.
Light is the fastest speed possible, but there is a sort of catch.
The universe is expanding at an accelerating rate, which means that it is inevitable that it will begin to expand faster than the speed of light (except it technically can't). The universe is expanding, but it is the expansion of space (the medium through which light moves). Whereas light is something that moves through a medium (space). We measure speed as a distance per unit of time, but the expansion of the universe is the creation of the distance (in a sense). So measuring the rate of expansion of the universe can't really be recorded as a distance per unit of time and isn't actually a speed. So, light is still the fastest thing in space/time

Minor correction, according to relativity light is not the fastest speed possible, it says no material object can travel AT the speed of light, techions are though to travel faster than light but are unable to move slower than light!. (yes, weird!)

I'm not a fizzicist, but it probably has something to do with all those quantums we keep hearing about.

No experimental evidence for tachyons; they are purely hypothetical. If they exist, they might be traveling backwards in time.
