I want to know If dark matter has not been directly observed, why do scientists feel the need to propose its existence and also If there is so much missing mass, why is the expansion of universe still accelerating?

Sindhuja, it would be great if you can add a little bit more detail on what you already know and what exactly is the sticking point in your understanding.


Experts are more willing to answer if the question gets more specific.


You can edit the original question to add the details.
