I don't know much about dark matter and I'm sure Einstein wasn't always 100% correct, but as for gravity, my bathroom scale just confirmed this morning that it is working fine and is stronger than ever.

1} Its a theory. We have discussed this before havnt we?.. The definition of Theory is "As far as we know right now" and open to re-interpretation, correction, improvement, and always open to discussion...
If we asked Einstein about his own definition of theory and his own theory of relativity, he would say, of course, if we can prove anything or bring anything to the discussion, we are most welcome.
But to say that there is no gravity?. Right away , he is wrong. There famously is that piece of video showing dust particles in a small bag in space, that PROVES there is a force of attraction in micro-gravity that isnt due to gravity alone, and therefore proves there is gravitational attraction between all matter. Even People floating about in space.
2} the theory has no wrong or right. You note I am not aiming at either theory here?... Its a theory, any theory, its just a theory, which is the best of our knowledge. Therefore, its not wrong, its not right, its the best fit we have right now, and of course open to correction in the future.
It is now the future, and I can correct the theory hat there is no such thing as gravitational attraction... There is a force of attraction. For brevity sake, whatever it is, we call it gravity. And its so good, we even keep it switched on at the weekend.
We do not know exactly what it is that creates the attraction forces between two masses, but we know it exists. We ourselves have not yet managed to alter that force because we dont know exactly what it is. But we know it exists. We have managed to "Interfere" with it by use of Magnets, another unexplainable force, but as yet, that is all. We know that Magnetic forces exist in items containing Iron, we do not know why its only Iron, but we know it exists, and we can re-create it by use of electricity.... In that, we know we can create magnetism. In that, we are ahead of gravity on that force. We can counter Gravity by use of lift thrust and other forces, but as yet, we do not know as much about gravity as we do about many other forces... Its the one of the four that we dont understand as much. The four fundamental forces being Gravity, Magnets, strong and weak nuclear forces. And we suspect at this time that they may be linked in some way...
3} so unless I see some strong proof that there is "Something else", to disprove one without proving "Something else" beyond all reasonable doubt, which this person does not, I cannot accept their theory as valid.
End of subject?.. Of course not, its just this is my theory, and therefore open to discussion. And yes I have read the link...
4} I tried watching the video but had to stop at time stamp 0:40, because I disagree with what he says "Why is there more gravity in a galaxy than we can explain" Quite simply, we have recently discovered that all galaxies are formed around a massive gravitational central force that we at this time know as "A Black Hole" As we do not know much about that massive gravitational force, we cant explain "how much" it contains, because we simply do not know... Therefore I suggest a certain person "Catch up" on his astrophysics, because if a mere truck driver from the north of England can make that kind of knowledge disagree with what he has to say, "There must be something" in what Prof Brian Cox has to say on the subject, and Brian seems to know more than he does, and certainly a lot more than I do... and he is where I am getting a lot of what I know, that and watching Discovery "How the universe works" and similar type programs, Disco Science is holding "Space week", I would watch it, but much of the programs they are running, I have already seen. More than once.
The final conclusion is that he is just offering another theory, and it is no more right or wrong than Einstein. But more wrong.
