<s>[INST] Is there an evidence that proves dark matter exists? [/INST] Yes, there is evidence that proves dark matter exists. The two pieces of evidence for dark matter come from the motion of stars and galaxies, and the bending of light in the universe, this tells us there's extra matter that can't be accounted for from observed luminous matter. While there isn't any direct evidence of dark matter, we can tell that there's something there which we appropriately named dark matter due to our inability to observe it directly through electromagnetic spectrum.</s>
