Recently, we realized the existence of unusual changes in GRS 1915+105, the prototypical Galactic Microquasar source of apparent superluminal jets. In the year 2023, this high-energy source presented major changes with respect to the historical values since its discovery three decades ago. The direction of the radio jets changed by 30◦ and the period of the oscillations of the accretion disk of gas to the black hole was reduce from 24m to 8m, in that year. Our analysis indicates that in 2023 the plane of the accretion flow to the black hole was aligned with the line of sight, which explains the deep X-ray obscuration and the high mid-infrared luminosity of the source observed with the James Webb Space Telescope (JWST) in that epoch. I will show that the apparent superluminal motions and the unusual changes observed in 2023, could be explain in the context of the Special and General Relativity theories of Einstein.
