The universe, being all there is, is infinitely big and has no edge, so there’s no outside to even talk about. Oh, sure, there’s an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. … The current width of the observable universe is about 90 billion light-years.
particularly, What is the biggest thing in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!
thus, Where is end of space?
It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe. Above the atmosphere is space. It’s called that because it has far fewer molecules, with lots of empty space between them.
in effect How long will the universe last?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.
Who created the universe?
A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.

How many Earths can fit in the universe?
By dividing the two volumes we get a factor of 3.2⋅1059, or written as decimal number: The observable comoving volume of the universe is about 320,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000-times the volume of Earth.
What is the smallest thing in the universe?
Quarks are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can’t be observed outside of their respective hadrons.
What is the smallest thing in the world?
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
How long is 1 hour in space?
How is 1 hour in space equal to 7 years on Earth.
Does space have a smell?
The fragrance was developed by Steve Pearce, according to Eau de Space product manager Matt Richmond. … Richmond said that he has struggled to describe how the fragrance smells, adding, “Astronauts describe the smell as a mix of gunpowder, seared steak, raspberries and rum.”
Does time ever end?
“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. … At least, not for another 3.7 billion years.
What will happen in 100 trillion years?
And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe with no stars, only cold black dwarfs. … The Universe will be completely dark.
What will be the last thing in the universe?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
Will the universe repeat itself?
Eternal return (also known as eternal recurrence) is a concept that the universe and all existence and energy has been recurring, and will continue to recur, in a self-similar form an infinite number of times across infinite time or space.
Who was the very first God?
Brahma is the Hindu creator god. He is also known as the Grandfather and as a later equivalent of Prajapati, the primeval first god. In early Hindu sources such as the Mahabharata, Brahma is supreme in the triad of great Hindu gods which includes Shiva and Vishnu.
Who is the real God?
In monotheistic thought, God is conceived of as the supreme being, creator, and principal object of faith. God is usually conceived of as being omnipotent, omniscient, omnipresent and omnibenevolent as well as having an eternal and necessary existence.
How many universes are there?
There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is one, only one universe.
How many Earths can fit in the biggest star?
Complete answer: We need to know that the diameter of VY Canis Majoris is 155000 times that of our Earth. Let us assume that nnumbers of Earth can be fitted into VY Canis Majoris. Therefore, we can conclude that 7.5477×1010Earths can be fitted into VY Canis Majoris.
How many Earths are there?
A recent study estimates there may be up to 6 billion Earth-like planets in our galaxy. “This is the science result we’ve all been waiting for,” co-author Natalie M. Batalha, an astronomer at the University of California, Santa Cruz, told ‘National Geographic’.
How many suns could fit in the universe?
You can fit 9.3 billion of our suns into VY Canis Majoris.
Is infinitely small possible?
According to the Standard Model of particle physics, the particles that make up an atom—quarks and electrons—are point particles: they do not take up space. … Physical space is often regarded as infinitely divisible: it is thought that any region in space, no matter how small, could be further split.
What is inside a quark?
Quark. A proton is composed of two up quarks, one down quark, and the gluons that mediate the forces “binding” them together. The color assignment of individual quarks is arbitrary, but all three colors must be present; red, blue and green are used as an analogy to the primary colors that together produce a white color …
What is the smallest thing in the human body?
A cell is the smallest independently functioning unit of a living organism.
What’s the smallest thing we can see with our eyes?
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.
