Have you ever wondered what lies beyond the universe’s edge? Well, a new and enigmatically shaped structure has been discovered just a few thousand light years from our own galaxy.
What is most interesting about this discovery is that it could help us understand more about the mysterious dark matter and the space-time continuum. Stay tuned to learn more about this exciting discovery!
Researchers have discovered that galaxy groups are all heading in the same direction. Researchers have concluded that this unexpected motion is happening for varying reasons to the expansion of the cosmos, and some have even speculated that a force from outside our observable universe may be to blame. The term “dark flow” has been coined to describe this breakthrough.
Invisible things in the cosmos have been found to have two separate impacts by cosmologists: dark matter is known to alter the spinning of galaxies, while dark energy seems to be driving the expansion of the universe to speed up. One of the newest members of the shady clan is dark flow.
Small oscillations in the cosmic microwave background (CMB) were analyzed in a recent research headed by Sasha Kashlinsky of the Goddard Space Flight Center in the United States and they revealed the finding. As the Big Bang’s thermal afterglow, the CMB demonstrates that the temperature of the cosmos is constant at 2.7 degrees above absolute zero. NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) has previously found evidence of tiny temperature fluctuations on the order of a thousandth of a degree in its surveys.
Kashlinsky’s research reveals that there is a systematic bias in the direction of these temperature changes with respect to certain clusters of galaxies. This means the clusters are moving relative to the rest of the cosmos, a motion that is separate from the expansion of the universe. This finding is remarkable because it contradicts our understanding of the distribution of stuff in the cosmos. It suggests that forces beyond our own may be at work, dragging the clusters apart.
The motion is very intriguing since it challenges explanations within the accepted paradigm. In fact, according to Kashlinsky, Before they finally came to believe it, they checked and double-checked it several times.
The strange motion, first detected in 2008 by the three-year WMAP survey, has now been validated by larger, five-year research. The dark flow was measured by Kashlinsky’s team out to a distance of 800 Mpc, using a sample size of 1000 galaxy clusters. In their earlier work, they were only able to follow motion to a distance of 300 Mpc.
Dark flow’s origins may be traced back to the early cosmos. According to their observations, they assessed the influence of space-time fragments that existed before the inflation of the universe.
According to inflation theory, the early cosmos was full of tiny bubbles, much like cosmic foam. When the universe was just 10-36 seconds old, one of these bubbles experienced a massive and fast expansion to form the cosmos as we know it today. Kashlinsky suggests that the bubbles in our vicinity are to blame for the movement of the clusters of galaxies.
“Inflation predicts that extra-universal structure will become visible at sufficiently massive scales. This motion is consistent with a world where these structures exist, and this is what we believe we are seeing”, he added.
For now, we have yet to understand the implications of these discoveries. However, you can be sure that scientists will be working day and night in order to unlock the secret behind this new discovery.
