What if our universe were to collide with another?
This is our home planet, Earth, and its satellite, the Moon, as we zoom out. Here we have our solar system, followed by the vast expanse of the Milky Way galaxy. We are but a minuscule dot amidst an infinite number of stars. Moving even further out, we encounter a cluster of galaxies, depicted as dots and swirls in the boundless space. Beyond that lies the Laniakea supercluster, where our galaxy resides. Continuing on, we come across the Hydra-Centaurus supercluster, which consists of immense clusters comprising thousands of galaxies. From this perspective, they appear no larger than a mere speck. Next, we encounter the Pavo-Indus supercluster, an expansive region spanning 200 million light years. As we continue to zoom out, we eventually witness the entirety of the observable universe. Each tiny dot within this vast expanse actually contains thousands of galaxies and an inconceivable number of stars. Scientists speculate that our universe may resemble a bubble, and it is conceivable that this bubble could collide with another universe. In fact, the existence of other universes is not out of the realm of possibility. It is even plausible that an infinite number of universes have emerged following the Big Bang. The occurrence of collisions between these universes is not impossible, as it may have transpired in the past.
The reason for the preservation of over 600,000 bird specimens at The Smithsonian is a topic of interest
Collection. Once acquired, the bird is meticulously prepared by specialists who ensure that the skin is preserved and maintained to the highest standards. This process is essential as the specimens are used for research purposes, such as identifying birds that have been killed by airplanes or studying evolutionary changes in duck bills.
Why Astronauts Do Not Wash Their Clothes
Some people believe that astronauts wear paper underwear while others are sure that the lack of gravity on space allows the grime to just float away. Unfortunately, NASA commissioned a machine for the International Space Station which was promptly scrapped due to concerns about astronauts not having access to laundry. However, luckily, fresh clothes get delivered to the station from Earth just like any other supplies. The only issue is that it happens not so often due to the high price of launching anything into space.
