There isn't any reason physics would work differently on Earth and Mars than it does in the next galaxy over. We can measure light from those galaxies so we know they're there and we've done enough tests on light to be confident in how it works.
Dark Matter wasn't 'invented'. It was hypothesised it had to be there because we can observe its effects on what's around it. Scientists do not know what it is, only that's it's there.
That science cannot explain everything isn't a flaw.
