Why do we live?
We live because there are people who love us, and people we love back.
We live because we want to find out things, and learn, and become able to do things that we would like to do.
We live because others want us to, and we want them to live along with us.
We live because we have hope, and want to see what happens next..
How Sun will die?
All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.
Are humans Stardust?
For decades, science popularizers have said humans are made of stardust, and now, a new survey of 150,000 stars shows just how true the old cliché is: Humans and their galaxy have about 97 percent of the same kind of atoms, and the elements of life appear to be more prevalent toward the galaxy’s center, the research …
Are humans star dust?
We Are Stardust—Literally. In this infrared image, stellar winds from a giant star cause interstellar dust to form ripples. There’s a whole lot of dust—which contains oxygen, carbon, iron, nickel, and all the other elements—out there, and eventually some of it finds its way into our bodies.
What are humans made of?
Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.
What will happen in 100 trillion years?
Every single day more than 400 million stars are formed. That’s about 4600 stars per second. But in 100 trillion years, Galaxies will run out of fuel and the formation of stars will stop. … As time passes, those remaining stars will also run out of fuel and universe will get colder and darkness will take over.
How many Earths can fit in the sun?
one million EarthsThe sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
Is Sun and Moon are living things?
Living things need food to grow, they move, respire, reproduce, excrete wastes from the body, respond to stimuli in the environment and have a definite life span. Water, sun, moon and stars do not show any of the above characteristics of living things. Hence, they are non-living things.
Can the Sun reproduce?
The sun most definitely does not grow! … (Some stars do explode – and eject debris from which other stars can form – but the Sun is too small to do that). Evolve – No. If you can’t reproduce than you can’t evolve.
Are stars living things?
not a living thing. It does use its mass to create energy, and it had a birth, has a life, and will have a death. But it cannot assimilate matter or energy for its use, like animals or plants, and it cannot reproduce. It is a contiuous fusion furnace, like a controlled hydrogen bomb explosion.
How old is the earth?
4.543 billion yearsEarth/AgeAge of the Earth. Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
Is virus a living thing?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Is a bushfire alive?
All living organisms is made of cells. Although fire needs oxygen to burn, this does not mean it is living. … However, fire is not alive. Living things require water to live and grow.
What Year Will our Sun die?
What will happen when the sun dies? But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago.
Why is the sun not considered alive?
For young students things are ‘living’ if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move. Others think plants and certain animals are non-living. … It is common for 5-7 year old students to have no conception of humans as animals.
What keeps a human body alive?
Oxygen. Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP.
Is a sun alive?
No. The sun does not use biological processes to produce its energy. … By almost any definition of life, the Sun is most surely not alive. The Sun, like every other star, is a giant nuclear reactor that fuses its Hydrogen into heavier elements, creating a lot of energy.
How are we still alive?
We are still alive because our heart is beating and oxygen is continuing to flow into our brain. … We are still alive because our heart is beating and oxygen is continuing to flow into our brain.
How long will the sun last?
So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
What happens when you die?
As death nears, it’s very common for a person’s breathing to change, sometimes slowing, other times speeding up or becoming noisy and shallow. The changes are triggered by reduction in blood flow, and they’re not painful. Some people will experience a gurgle-like “death rattle”.
Is an apple living or nonliving?
An apple can reproduce. That makes it living. But a seed isn’t active.
