Who made humans?
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means ‘upright man’ in Latin.
Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago..
Can an atom be seen?
Atoms are extremely small measuring about 1 x 10-10 meters in diameter. Because of their small size, it’s impossible to view them using a light microscope. While it may not be possible to view an atom using a light microscope, a number of techniques have been developed to observe and study the structure of atoms.
Do particles exist?
Everything around us has been found to be made of particles. The corresponding branch of physics is particle physics.  The wavefunction used in some formulations of quantum mechanics is not a physical wave, but an unobservable mathematical function.  Quantum particles are not Newtonian particles.
Are we really 70 water?
About 70 percent of the human body is made up of water and, coincidentally, more than 70 percent of Earth is covered in water. Water creates an environment that sustains and nurtures plants, animals and humans, making Earth a perfect match for life in general.
Can you destroy a black hole?
Black holes are among the most destructive objects in the universe. … There is nothing we could throw at a black hole that would do the least bit of damage to it. Even another black hole won’t destroy it– the two will simply merge into a larger black hole, releasing a bit of energy as gravitational waves in the process.
Can you destroy energy?
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. … In other words, energy cannot be created or destroyed.
Is human made of sand?
In Norse culture humans are made from sand in tree trunks. In the Korean Seng-gut narrative, humans are created from red clay. According to the beliefs of some Indigenous Americans, the Earth-maker formed the figure of many men and women, which he dried in the sun and into which he breathed life.
Who was the first human?
Homo habilisThe First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
How are humans born?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.
Are humans made of atoms?
About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. … Nuclei are around 100,000 times smaller than the atoms they’re housed in.
Where do humans originate?
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa.
Is the human body made of water?
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Is everything made up of matter?
Matter is the “stuff” that makes up the universe — everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons.
Do atoms die?
Since an atom has a finite number of protons and neutrons, it will generally emit particles until it gets to a point where its half-life is so long, it is effectively stable. … It undergoes something known as “alpha decay,” and it’s half-life is over a billion times longer than the current estimated age of the universe.
Are humans a solid?
Our our body, bones and some other inner body parts are solid but our body also contain liquids( water, blood, acid etc) and gases( air, oxygen, co2 etc). So, our body is look like solid object but it contains multiple states of matter.
Are humans made of stardust?
Stars that go supernova are responsible for creating many of the elements of the periodic table, including those that make up the human body. ‘It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas. …
Does matter exist?
Matter exists in various states (also known as phases). These include classical everyday phases such as solid, liquid, and gas – for example water exists as ice, liquid water, and gaseous steam – but other states are possible, including plasma, Bose–Einstein condensates, fermionic condensates, and quark–gluon plasma.
Where does your energy go after you die?
The pattern of the energy flow as the person nears death becomes thin and draws in toward the physical body, and the chakras close from the feet upward in the cases experienced.
Can matter be created?
Water is composed of two hydrogen atoms bonded to an oxygen atom. Photograph by OJO Images Ltd. From port-a-potties to supernovas, matter makes up everything visible in the known universe. Because matter is never created or destroyed, it cycles through our world.
Are humans made of matter or energy?
all matter and psychological processes — thoughts, emotions, beliefs, and attitudes — are composed of energy. When applied to the human body, every atom, molecule, cell, tissue and body system is composed of energy that when superimposed on each other create what is known as the human energy field.
What matter is the human body made up 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. All 11 are necessary for life.
