Could Superman access the Speedforce?

If Superman sun dips and then runs/flies as fast as he possibly can, could he access the speedforce?

No.

Nope

Theoretically he could, but not in the way you described.

No. But in the off-chance he did gain the speed-force he would be pretty damn OP. Assuming he'd be on par with Wally.

@koshi_waza88: But what makes The Flash "worthy" of the Speedforce? Because i'm pretty shure Supes is potentially faster than Flash.

@justthatkid: Flash took SBP to the Speed Force. E1&2 Supes rushed SBP and SBP told them that even if they took him to the Speed Force he would just break out. They weren't planning on taking him there, they actually planned on taking him through the Red Sun, but SBP just assumed they were. I don't know if this implies that is possible for a non Flash to tap into the Speed Force.

No.

Well, plenty of people who aren't The Flash can tap into the Speed Force. Theoretically, anybody should be able to tap into it. Barry was struck by lightning that could be himself from the future, (not sure if that's still true,) and the same thing happened to Wally pre-Flashpoint.

Freak accidents (at least they were at one point.) So...it's possible, that if Superman was struck by lightning and got doused/inhaled the same chemicals, he could access the Speed Force.
