There is currently no observational evidence of the existence of cosmic strings, and the CMB evidence proves they are not abundant. One of the most promising ways to detect these elusive objects is to search for the gravitational-wave radiation they would produce.There is currently no observational evidence of the existence of cosmic strings, and the CMB evidence proves they are not abundant.

What causes cosmic strings?
According to some calculations, the cosmos might have cooled so quickly that the fabric of space-time became fractured, creating a network of whisper-thin tubes filled by pure energy that stretch across the breadth of the observable universe. This is one possible origin story of cosmic strings.
Is the universe a string?
String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, many billions of times smaller than an individual proton within an atomic nucleus.
What do you mean by cosmic strings?
Definition of cosmic string : any of a class of hypothetical supermassive astronomical objects that are extremely thin but are millions of light years long and that are postulated to have formed very early in the history of the universe.
Is it possible to bend time?
Science does support some amount of time-bending, though. For example, physicist Albert Einstein's theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.)
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time.
Is Super asymmetry real?
Saltzberg said super symmetry is an actual thing but no one has ever talked about super asymmetry. There are no papers that mention it, which is a line that we put in the script for Leonard. David was on set during the finale taping and wrote all the equations on the mirror to make sure the science was right.
Where are cosmic strings?
These cosmic strings stretch from one end of the observable universe to the other and are one-dimensional defects in space-time itself. As the universe grows, the strings grow right along with it, because they are simply a part of the underlying fabric of space.
What are superstrings made of?
Each vibration mode corresponds to a different particle and determines its charge and its mass. In the current understanding of the theory, those strings are not "made of" anything: they are the fundamental constituent of matter.
Can we create wormhole?
To create a wormhole on Earth, we'd first need a black hole. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.
