# How small are we in the scale of the universe?

## Is the universe infinite in size?

The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us.

## How big is the universe in miles?

It’s about 238,855 miles on average, and I say on average, because the distance does change. The moon does not orbit the Earth in a perfect circle, but that’s kind of an abstract thing, and it doesn’t really mean anything to you, right?

## What’s beyond the universe?

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.

How small are we in the scale of the universe? – Related Questions

## What is bigger than the universe?

No, the universe contains all solar systems, and galaxies.

## How far is it to the edge of the known universe?

When we take all of the available data together, we arrive at a unique value for everything together, including the distance to the observable cosmic horizon: 46.1 billion light-years. The observable Universe might be 46 billion light years in all directions from our point of view,

## How far does the universe go?

The cosmos is only so old, and light only travels so fast. So, in the history of the universe, we haven’t received light from every single galaxy. The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies.

## How big is the universe compared to the Milky Way?

We Must Go Smaller. If our Milky Way galaxy, which is around 125,000ly across was to be shrunken down to a grain of sand, the observable universe would be roughly 372 meters (1220 feet) wide, not too bad.

## Why can we see 46 billion light-years?

That’s because over time, space has been expanding, so the distant objects that gave off that light 13.8 billion years ago have since moved even farther away from us. Today, those distant objects are a bit more than 46 billion light years away.

## How long would it take to go 13 billion light-years?

This galaxy is thought to be about 13.2 billion light years away, which means it would date to about 500 million years after the Big Bang.

## What is the farthest thing in the universe?

Astronomers have measured the distance to the farthest cosmic object known to humankind: a galaxy that lies 13.1 billion light-years away. Imaged last year by Hubble’s new Wide Field Camera 3, the galaxy takes researchers back to a mere 600 million years after the big bang.

## What’s the farthest thing from Earth?

The most distant object ever seen from Earth may have just been discovered. HD1 is an object estimated to lie around 13.3 billion light years away from our planet, placing it in an era when many chemical elements were yet to form.

## What is the oldest thing in the universe?

Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.

## Is there life in other galaxies?

Generally, they conclude, life is possible only in the outer regions of large galaxies. (Our own solar system is about 27,000 light-years from the center.) Things are even bleaker in other galaxies, the researchers report. Compared with the Milky Way, most galaxies are small and low in metallicity.

## How far in space have we seen?

The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.

## How many universes are there?

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.

## What is at the end of space?

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.

## What’s on the other side of space?

If space is infinite, there is nothing on the other side. If space is finite because it has been bent around upon itself because of gravity, then again there is nothing on the other side of it because there is no seam. It looks like the surface of a smooth ball which represents a piece of flat paper bent upon itself.

## How cold is space?

Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops. But this temperature is not constant throughout the solar system.

## What created the universe?

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.

## Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.
