Physics - increase gravity speed without making balls fall through planes

Question

If I make a simple sphere with scale (1, 1, 1), the physics look "slow".
Now if I shrink the sphere to scale (0.01, 0.01, 0.01), the physics look "faster."
HOWEVER, this sphere tends to fall through planes, even with SphereColliders and RigidBody attached.
I know that this happens because the Unity physics engine doesn't work well for small objects.
So is there a way to have small, fast-moving objects while avoiding this glitch?

To prevent objects from going through other colliders, set the rigidbody's collision detection mode to anything but discrete. Also, if your sphere seems to be falling slowly at a scale of (1, 1, 1), just increase the gravity in the Physics settings.
