The James Webb Space Telescope discovered mysterious red points, possibly birthplaces of supermassive black holes, in the early universe.
Mysterious red points discovered in early universe
The James Webb Space Telescope has detected unusual red points called Little Red Dots (LRD) at the edges of the early universe. These points are surrounded by thick dust clouds and emit red light, leading scientists to speculate they might be sites where supermassive black holes began to form.
Link to massive early stars proposed
Recent studies suggest that these mysterious red points could be connected to the formation of Very Massive Stars (VMS), which are extremely large stars that existed in the early universe. These stars are thought to have been much more massive than typical stars seen today.
Evidence from distant galaxies
Distant galaxies like COLA1 show signs of intense ultraviolet light and high levels of nitrogen. These features point to the presence of stars with masses over 100 times that of the Sun. These massive stars could have influenced their surroundings in ways that challenge current understanding of stellar behavior.
Formation through star collisions
The creation of such massive stars is believed to occur through a process called "runaway collisions" or "cascading fusion" in dense star clusters. In these clusters, stars collide repeatedly, merging and growing until they form extremely massive stars, sometimes thousands of times the mass of the Sun.
Link to black hole origins
A supermassive star of this size would eventually collapse, forming a seed for a supermassive black hole. This black hole would initially have a mass of thousands of solar masses but could grow over time by absorbing surrounding material, eventually becoming the massive black holes found at the centers of galaxies today.
