Earth ends and outer space starts
at the Kármán line
, some 62 miles (100 kilometers) above the planet’s surface.
Where does the space end?
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.
How does space go on forever?
So why do scientists think that space goes on forever?
It’s because of the shape of space
. Our part of space, or the observable universe, has a special shape: it is flat. … In fact, you would always stay exactly the same distance apart, within the observable universe.
Where does the space start?
The boundary of
space
However, the Fédération Aéronautique Internationale (FAI), which oversees air sports and human spaceflight records, considers the Kármán Line — 100 kilometers (about 62 miles) above Earth’s surface — to be the
start
of
space
.
Where does the sky end and space begins?
Between 500 and 1,000 kilometers above us
is the beginning of the exosphere, which extends halfway to the moon. And, as solar radiation overcomes the power of Earth’s gravity, it’s here that Earth’s atmosphere officially ends – and the sky’s limits are finally reached.
Does space have a bottom?
The Bottom of the Universe.
The universe has a bottom
. That bottom extends infinitely outward and has an infinite sky above it, with an infinite number of stars and galaxies. The bottom is remarkably terrestrial, with gravity, mountains, lakes, forests, and sunshine, each of which deserves additional discussion.
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. But Buosso and co have some comforting news too.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin
(about minus 455 degrees Fahrenheit)
. But space is mostly full of, well, empty space.
How far in space have we gone?
The most distant human-made object is the spacecraft Voyager 1, which – in late February 2018 – is
over 13 billion miles (21 billion km)
from Earth. Voyager 1 and its twin, Voyager 2, were launched 16 days apart in 1977.
Why is space so big?
In between the galaxy groups and clusters in the Universe lies the majority of its volume, and it’s mostly empty space. A map of more than one milion galaxies in the Universe, where each dot is its own galaxy. … But the reason the Universe is this large today is
because it’s expanded and cooled to reach this point.

What is the limit of sky?
—used to say that
there are no limits
and that anything is possible You can achieve anything if you really want to. The sky’s the limit.
What height does space begin?
The Fédération Aéronautique Internationale (FAI) agrees with Blue Origin and defines the beginning of space as the Kármán line. The recognized imaginary boundary of space is at an altitude of
about 62 miles
.
At what height does the Earth’s atmosphere end?
The final layer of the atmosphere, the enormous exosphere, continues until
around 6,700 miles (10,000 km)
above the surface of our planet (and some say even further).
