In the first hundreds of millions of years after the Big Bang, objects appeared in the Universe whose existence no one expected. The James Webb Space Telescope discovered them only recently, and today they are considered one of the greatest mysteries in modern astrophysics.
These objects were given the name "Little Red Dots." They are unlike young galaxies or familiar supermassive black holes. They are too bright, too compact, and appeared too early to fit into existing models of the Universe's evolution.
Recent studies suggest an unexpected explanation: perhaps we are looking at a completely new type of cosmic object, Black Hole Stars. If this hypothesis is confirmed, they may prove to be the missing link between the first stars, the oldest quasars, and early galaxies, and also help resolve one of the main questions in modern cosmology, the so-called "Early Universe Crisis."
At the lecture, we will discuss:
- •What exactly the James Webb Telescope saw;
- •Why the "Little Red Dots" left astrophysicists baffled;
- •What Black Hole Stars are and why this idea is generating so much discussion;
- •How new discoveries may change our understanding of the birth of the first galaxies and black holes;
- •Which questions still remain unanswered and what astronomers hope to learn in the coming years.
This is a lecture about how one unexpected discovery can change our understanding of the history of the Universe.
When: April 18 at 17:00
Where: Tallink Hotel
The lecture will be held in Russian.
