Yes, new planets are indeed being formed in various regions of the universe. The process of planet formation typically occurs within protoplanetary disks, which are flat, rotating disks of gas and dust surrounding young stars. Over millions of years, the dust grains within these disks come together through mutual gravitational attraction and collisions, gradually forming planetesimals (small planetary building blocks) and eventually protoplanets.
However, the timescale for a planet to form completely can vary significantly and is influenced by numerous factors, including the mass of the protoplanetary disk, the composition of the materials within it, and the distance from the central star. Generally speaking, the process of planet formation is a lengthy one, typically taking millions to tens of millions of years for a planet to fully develop.
The notion of a planet forming in precisely seven days is not consistent with our current understanding of planetary formation. Planetary formation is a complex and gradual process that requires the accumulation of material over extended periods of time.
