Most people believe that space is just an emptiness in which things happen, similar to a large empty warehouse or a theater stage on which the events of the cosmos take place. According to this point of view, space is essentially the absence of objects. It's a gap that has to be filled, as in "I saved room for dessert" or "I discovered a nice parking spot."
However, some scientists believe that all space is actually full of matter that we can't see. Energy comes in different forms, such as light and heat. Just as waves move through water, energy waves move through space. These waves carry information with them, but we can only understand this information when we develop ways to detect it. For now, all we know is that there is much more matter out there than what we can see.
Our current understanding of physics tells us that if there were no empty space, then nothing could exist. Anything that exists must occupy space. Since nothing can fill space, it follows that space must be empty.
However, science has not yet explained what happens after the Big Bang. If the Universe was once smaller than an atom, then something would have had to give to make it that size. Maybe space itself grew larger during that time period, or perhaps there are other possibilities. The fact is that we don't know.
All we can say for sure is that once upon a time there was nothing, and then there was something.
The zone above and surrounding our globe where there is no air to breathe or light to disperse is referred to as space. Although space is a vacuum, it is far from empty. Go directly to the main material.
Science used to think of space as "nothing," in the sense that when all matter and energy were eliminated, there was "nothing" left. But this view has changed over time.
The near-vacuum between celestial bodies is known as space, often known as outer space. It is the location of everything (planets, stars, galaxies, and other objects). This is the point at which the Earth's atmosphere is considered to end and outer space starts.
Space is vast and empty, with only a few small particles in orbit around Earth (such as dust clouds and meteoroids) and some gases such as oxygen and carbon dioxide. There are also certain types of radiation that come from outside of our solar system that affect how DNA functions inside living things; these include ultraviolet light, which causes skin cancer; X-rays, which can damage internal organs; and gamma rays, which are high-energy electromagnetic waves that occur during nuclear reactions and explosions.
In conclusion, there is no air to breathe out here. You would asphyxiate after a few minutes without oxygen. There is no water to drink, except maybe what's in Earth's oceans. And there are no plants to eat because you'd starve to death before you could digest your way out of this situation.
We consider the space that spans the distance between us and those stars to be empty. Emptiness may be defined as a volume of space that contains "nothing" in the most literal meaning of the word. There are no atoms, elements, molecules, protons, neutrons, quarks, or electrons. Thus, nothing at all is occupying any part of this space.
It should be noted that although we can't see anything inside black holes because light is trapped by the gravitational force, it isn't really empty. The interior of a black hole is called "empty" only in comparison with everything else in the universe. If you fell into a black hole you would be crushed down to a point where your body's atoms would be squeezed together until they formed a tiny ball with an infinite density. However, since this happens before you hit the singularity at the center of the black hole, you wouldn't actually experience death; you would just experience eternal crushing pain as your body was compressed beyond repair.
The concept of empty space has many implications for physics. One important implication is that empty space does not exist. Space is never completely empty, and anything that can be used to measure distance or time also counts objects that we cannot see. Even if you could look deep enough into space using telescopes, you would still find objects that exert forces on bodies that are capable of moving them: photons from distant galaxies, particles emanating from the decay of radioactive elements, etc.
Space looks as a black blanket speckled with stars because there is no air to disperse sunlight and generate a blue sky. Space is commonly thought to be absolutely empty. In fact, it is filled with many particles such as dust clouds that block light from reaching the moon or planets beyond. The dust clouds are why objects in deep space appear faint when viewed through telescopes on Earth.
The universe is full of mystery and wonder, and exploring it is what science is all about. It's difficult work but anyone can do it! All you need is a good idea and some talent for mathematics and science. I would recommend starting with astronomy because so much mysteries have been solved already. Then move onto physics or biology, these fields are very cool too!
Science is based on facts collected by scientists who use their minds to understand how the world works and learn new things. Science helps us answer questions like "Why are trees green?" "How does electricity flow through wires?" and "Why does my phone not work now? ”. It also helps us make discoveries like the theory of evolution and the structure of atoms. Science is used in everything we see around us including computers, smartphones, and medicine.
You can become a scientist too if you want. There are many paths you can take to reach this goal.
