Using Einstein’s theory of relativity to power the cutting-edge ALMA telescope array in Chile to bend space-time, scientists have obtained an 11 billion year old ghost.
According to Science live, This is a picture of the world 11 billion years ago, capturing a young and invisible galaxy in all wavelengths. It is literally a ghost because in real time this galaxy could be very old or no longer exist.
Get moment of “time travel” Here, scientists used scientist Albert Einstein’s theory of general relativity, which emphasizes the large mass object – like galaxies or giant stars – can be powerful enough creates a certain “curvature” of space-time thanks to the giant gravitational field.

A group of scientists from the Italian School of Advanced International Studies (SISSA) took advantage of something like this to “magnifying glass” universe, an effect called “gravitational lens” Helps to significantly increase the power of ALMA, which is already an extremely powerful radio telescope array.
Thanks to “Bend” At that time, a valuable ALMA photo captured the blurred outlines of a galaxy that should be invisible.
At the time of observation, this galaxy was very young and formed 1,000 times more stars than the galaxy today containing our Milky Way.
“Distant galaxies like this, young and small, are characterized by intense star formation, are largely obscured by dust, and contain a very rich reservoir of molecular gas, a precursor to other galaxies.” closer universe” – said co-author, astrophysicist Andrea Lapi from SISSA.
Galaxies like “spectrum” The newly recorded discovery also provides particularly valuable information about the processes that lead to the formation and evolution of structures in today’s universe.
