OpenAI reports the dyadic Erdős similarity case

For every eta in (0,1), there is a compact subset of [0,1] of measure greater than 1−eta that contains no affine copy of {2^(−n):n>=1} under any translation or nonzero real dilation of either sign.

Understanding the problem

Read the background

For every eta in (0,1), there is a compact subset of [0,1] of measure greater than 1−eta that contains no affine copy of {2^(−n):n>=1} under any translation or nonzero real dilation of either sign.

Why it matters

If correct, proves that the dyadic sequence is not measure universal, a geometric-progression case of the Erdős similarity conjecture.

What counts as progress

Can a compact set of almost full measure avoid every affine copy of the dyadic sequence?
