Are humans closer to the size of an atom or the universe?
The universe is on the order of 100 trillion trillion meters, or 1E+26 m. Humans are on the order of one meter, so we are about 10 billion times the size of an atom, and the universe is about 100 trillion trillion times the size of us. So we're much closer to atom-sized than universe-sized.
According to all current observations, there is no center to the universe. For a center point to exist, that point would have to somehow be special with respect to the universe as a whole.
About 80 per cent of the normal variation in human height is the result of inherited genetic differences between people, with the rest of the height difference being due to environmental influences, such as diet or upbringing.
But really, 'large' and 'small' only make sense in relation to some other object: We are about as large as trees, smaller than the moon, much smaller than the sun and much larger than atoms.
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
But this is really just our best guess – nobody knows exactly how big the Universe really is. That is because we can only see as far as light (or more accurately the microwave radiation thrown out from the Big Bang) has travelled since the Universe began.
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today. Or at least, that's what we've been told by physicists for the past several decades.
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
In the prehistoric populations, the maximum height for men was 165 to 170 cm, while women topped out at 160 cm. Today, by comparison, men in England have an average height of around 175 cm, while for women it is about 162 cm.
How tall were humans 40000 years ago?
40,000 years ago: European males – 183 cm (6 feet). Cro-Magnon people were the first modern humans (Homo sapiens) to inhabit Europe.
Several studies corroborate the fact that our ancestors were far stronger than us, and that human strength and fitness has decreased so dramatically in recent years that even the fittest among us wouldn't be able to keep up with the laziest of our ancestors.
The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
No, you can't see an atom the way we're used to “seeing” things – that is, using our eyes' ability to perceive light. An atom is simply too small to deflect visible light waves, which means it won't show up under even the most powerful light-focusing microscopes, Oncel said.
Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.
Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
We have come to understand the fundamental building blocks of ordinary matter, and what we know of the universe is only a tiny fraction of what is out there. We know only five per cent of the universe. The remaining 95 per cent is still a mystery – an unknown universe of new particles and forces awaits discovery.
Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space. But nobody knows for sure.
Who created the God?
No one created God. God got created as the universe grew and changes. God is the cumulative energy of the universe. So, infact universe created God.
Nothing. Since the world was created out of nothing (ex nihilo), nothingness prevailed. Therefore God was idling, just existing, perhaps contemplating creation.
The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn't occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Answer and Explanation: There is no current name for our Universe, other than simply "the Universe", although we have names for our own home in the cosmos. Earth is part of the solar system of planets revolving around our Sun. The Sun is one of hundreds of billions of stars in the Milky Way Galaxy.
Our universe is also called the cosmos. It is originally a greek word. In early days it was thought that our Galaxy constituted the entire universe.
Observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of thermodynamics or relativity. There are also technical challenges: it might be possible but would involve vast amounts of energy.
No, they don't believe there's an end to space. 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.
He may have stood about 5-ft. -5-in. (166 cm) tall, the average man's height at the time.
How tall were the Vikings?
"The examination of skeletons from different localities in Scandinavia reveals that the average height of the Vikings was a little less than that of today: men were about 5 ft 7-3/4 in. tall and women 5 ft 2-1/2 in.
In a paper published in Nature, the researchers show that northern Europeans seem to have a stronger genetic link to a particularly tall nomadic population from the Eurasian steppe who came to Europe around 4,500 years ago. Because of these genes, northern Europeans are still tall compared to others on the continent.
Scientists say humans would have had a "leaner" physique with long legs and narrow hips around 1.5 million years ago. Our ancient ancestors went through a tall and skinny phase around 1.5 million years ago, according to new research.
Hominins from four million years ago weighed an average of 25kg and stood between 125cm and 130cm tall. The appearance of our own species family, Homo, around 2.2-1.9 million years ago saw a surge in both height (20cm) and weight (15-20kg).
Genetic studies have demonstrated that humans are still evolving. To investigate which genes are undergoing natural selection, researchers looked into the data produced by the International HapMap Project and the 1000 Genomes Project.
Strength peaks at age 25.
Your muscles are at their strongest when you're 25, although for the next 10 or 15 years they stay almost as hefty — and this is one of the traits that can be most easily improved, thanks to resistance exercise.
Even at full effort, most people do not generate 100 percent of the force their muscles can physiologically produce, Jenkins said.
Our ancestors' lives were unpredictable. They had to do a lot of running to catch food and escape danger, but they also needed to keep muscle mass to a minimum because food was limited. Seen through this lens, losing condition is an adaptation in itself.
That's about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
There's a limit to how much of the universe we can see. The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
What is the smallest thing ever?
The smallest thing in the world is the quark.
For many years, scientists thought the atom was the smallest thing there was. Then they split the atom and found electrons. After the particle accelerator was invented, they broke the atom into as many small pieces as they could. These little pieces are called quarks.
According to the law of conservation of energy, the matter cannot be created nor be destroyed. Hence, an atom cannot be destroyed and it cannot be broken into smaller particles. The atoms mainly consist of three primary particles and that is electron, proton, and neutron.
3. If "touching" is taken to mean that two atoms reside in the exact same location, then two atoms never touch at room temperature because of the Pauli exclusion principle. The Pauli exclusion principle is what keeps all the atoms in our body from collapsing into one point.
The smallest thing that we can see with a 'light' microscope is about 500 nanometers. A nanometer is one-billionth (that's 1,000,000,000th) of a meter. So the smallest thing that you can see with a light microscope is about 200 times smaller than the width of a hair. Bacteria are about 1000 nanometers in size.
Within a few days, however, the temperatures would begin to drop, and any humans left on the planet's surface would die soon after. Within two months, the ocean's surface would freeze over, but it would take another thousand years for our seas to freeze solid.
No. The Earth has a lot of mass and moves extremely quickly in its orbit around the Sun; in science speak, we say its 'momentum' is large. To significantly change the Earth's orbit, you would have to impart a very great change to the Earth's momentum.
You can get surprisingly close. The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up.
The size of an average human is 176.5 cm or 1.76 m while the diameter of the solar system alone is 287.46×1011m. Therefore, the solar system is about 163.33×1011 times greater than a human then the universe must be infinite times greater than a human.
For a reference of size, humans are usually under 2 m tall, atoms are approximately 10-10 m across, and nuclei are approximately 10-15 m across.
It has an estimated 350-billion large galaxies (like the Milky way). It houses about 30-billion-trillion stars; that is 30,000,000,000,000,000,000,000 stars! The Earth is about 3.5 million times larger than a human. The Solar System is about 36 billion times larger than Earth (3.6 X 10^10).
How much bigger is the universe than an atom?
The universe is on the order of 100 trillion trillion meters, or 1E+26 m. Humans are on the order of one meter, so we are about 10 billion times the size of an atom, and the universe is about 100 trillion trillion times the size of us. So we're much closer to atom-sized than universe-sized.
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Humans are getting taller; they're also fatter than ever and live longer than at any time in history. And all of these changes have occurred in the past 100 years, scientists say.
So small, in fact, that it's impossible to see one with the naked eye, even with the most powerful of microscopes. At least, that used to be true. Now, we have a photograph that shows a single atom floating in an electric field, and it's large enough to see without any kind of microscope.
The animation claimed that if the atoms in a penny were the size of tennis balls, the penny would cover the distance between New York and Dublin, Ireland, or about 4900 km.
