[MCU] On the opening of Infinity war.

Couldn't Thanos have intercepted Banner traveling through the bifrost by using the space stone?

He seemed pissed enough at Heimdal for sending Banner away so couldn't he have just used the space stone to teleport Banner or redirect the bifrosts trajectory?

Asgardian tech seems to trump even the Infinity Stones in some cases.  For example, at the end, Thor throws Stormbreaker into Thanos' chest, Thanos attempts to intercept the axe with infinity gem beams, and *fails*.  

It could be that the Bifrost is the same way, it just beats the Space Stone.
