Universe

Hi everyone, I hope that you all are enjoying and staying safe in this critical and problematic situation. Well, today I am gonna talk about the universe.

The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. During the Big Bang, all of the space, time, matter, and energy in the Universe was created. This giant explosion hurled matter in all directions and caused space itself to expand. As the Universe cooled, the material in it combined to form galaxies, stars, and planets.

Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.The universe is the name that we use to describe the collection of all the things that exist in space. This is because the light from distant parts of the universe takes a very long time to reach us. ... From these observations, it seems the physical laws and constants of the universe have not changed. The fate of the universe is determined by its density.According to astronauts, they all smell like space. While each astronaut smells something a bit different, they all agree 'space stinks'. Obviously, space is a vacuum, so no one has really 'smelled' it before in the traditional sense of the word. ... But we can smell it indirectly

Our universe is very vast and it never ends. The things that lie in our universe are-

1= Galaxy
2= Stars
3 = Meteors,Comets and asteroids

Hey do you know there is end of the space somewhere.No, just joking there is no end of space.The universe never ends but it's also constantly expanding. Scientists don't think there is a true edge of the universe. But there's an end to what humans can see of the universe. This is called the edge of the observable universe. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze".The universe we live in may not be the only one out there. In fact, our universe could be just one of an infinite number of universes making up a "multiverse." Though the concept may stretch credulity, there's good physics behind it.However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.

I hoped you liked this blog and you found it interesting. So, this is all for today and enjoy the rest of your day.

  Benefits of the Health and Nutritions Kinjal Sep 16 2021 Food and nutrition  are the way that we get fuel, providing energy for our bodies. We need to replace nutrients in our bodies with a new supply every day. There are many high-quality, free guidelines available for healthy eating plans that give more details on portion size, total calorie consumption, what to eat more of, and what to eat less of to get healthy and stay that way. Even if you are getting enough to eat, if you are not eating a balanced diet, you may still be at risk for certain nutritional deficiencies. Also, you may have nutritional deficiencies due to certain health or life conditions, such as pregnancy, or certain medications you may be taking, such as high blood pressure medications. People who have had intestinal diseases or had sections of intestines removed due to disease or weight loss surgery also may be at risk for vitamin deficiencies. Alcoholics are also at high risk of having nutritional defic...

  Space Station Author : Ayushi Singh Hello Readers, Today, I'll tell you about a man made phenomenon that filled our dreams of residing in space and explore the wonders of the space station! So what is a space station? The international space station is a large spacecraft that orbits around the earth, it is a home were astronauts stay during their space mission, but the vital question is, why do we build it in the first place? Well as they say, curiosity is the essence of human existence, and it has taken us to the deepest parts of the ocean, to the tallest mountains, to every unexplored part of the world and even beyond it, into space! Scientists around the world are always around their toes to explore the wonders of the universe, but soon they realize that it isn't possible within the confinement of the four walls of a lab to learn about space, and concluded that if they needed to know more about space then they would have to stay in space. So to facilitate the research, ga...

  LIFE DURING PANDAMIC SREELAKSHMI Aug 04 2021 I would like to express my feelings about how our life has changed during the pandamic. We have lost all the freedom we had. Many people cannot travel like they used to, they cannot meet their families and cousins. Whoever had travelled during the pandamic are stuck in diffrent places unable to return home on time. With the school being closed and students unable to to meet their friends in person. The pandamic has changed everything like the way we communicated and more.  Children are not able to run around and play. Masks and sanitizers have become essential items in every household. I believe that many people in the wrld are trying to find a way to destroy the virus and help us live our life filled with freedom & happiness. Saying this I Sreelakshmi is going to stop by reassuring you that we can fight the pandamic together, I also request all to follow the health instructions by the health care providers and doctors. All mu...
