Who created earth?
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula.
Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen..
What colors do color blind people see?
Most colour blind people are able to see things as clearly as other people but they are unable to fully ‘see’ red, green or blue light. There are different types of colour blindness and there are extremely rare cases where people are unable to see any colour at all.
What does E mc2 mean?
E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Where did all matter come from?
That’s because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe. As the early universe cooled, the matter produced in the Big Bang gathered into stars and galaxies.
Is the quantum realm real?
The quantum realm (or quantum parameter) in physics is the scale at which quantum mechanical effects become important when studied as an isolated system. Typically, this means distances of 100 nanometers (10−9 meters) or less, or at very low temperatures (extremely close to absolute zero).
Is nothingness possible?
There is no such thing as nothingness, and zero does not exist.
What Cannot be created or destroyed?
The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.
Can an atom be in 2 places at once?
Physicists call this phenomenon “quantum superposition,” and for decades, they have demonstrated it using small particles. … 23 in the journal Nature Physics, an international team of researchers has caused molecule made up of up to 2,000 atoms to occupy two places at the same time.
What is outside the universe?
Encountering the Unknown Despite its strangeness, this first idea is one of the easiest to digest. 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.
Does nothing have a color?
Nothing actually “has a color”. … If you look at an object in a “black light”, for example, you will see a completely different color, because the wavelength of light is outside the range that the cells in the retina can receive.
What is the color of nothing?
BlackOur eyes capture the light reflected from a particular object, and hence we are able to see it’s colour, which is a part of the visible spectrum. So, an empty Universe will have no colour, cause it’s empty. Hence, colour of nothing is Black, cause there is no colour as Black, it’s just empty !
Do things exist when not observed?
The idealist philosopher George Berkeley argued that physical objects do not exist independently of the mind that perceives them. An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.
Does the universe have an end?
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Are there other universes?
In fact there are almost too many other potential universes. Physicists have proposed several candidate forms of “multiverse”, each made possible by a different aspect of the laws of physics. The trouble is, virtually by definition we probably cannot ever visit these other universes to confirm that they exist.
Can you create something from nothing?
“Therefore, creating a closed universe out of nothing does not violate any conservation laws.” Vilenkin’s calculations show that a universe created from nothing is likely to be tiny, indeed — far, far smaller than, say, a proton.
Can matter be created?
The first law of thermodynamics doesn’t actually specify that matter can neither be created nor destroyed, but instead that the total amount of energy in a closed system cannot be created nor destroyed (though it can be changed from one form to another).
How could the universe come from nothing?
Quantum mechanics tells us that “nothing” is inherently unstable, so the initial leap from nothing to something may have been inevitable. Then the resulting tiny bubble of space-time could have burgeoned into a massive, busy universe, thanks to inflation.
