There’s nothing in the bottom of the space, or let’s say there isn’t any “bottom” of the space to begin with. When you’re in space, you aren’t supposed to address anything with the words ‘up’ & ‘down’, because it really gives the hard time for other people to refer it.

What is at 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.
What is below in space?
“Above” and “below” are determined by an external gravitational field. Earth is flying through space, for sure, but this space does have a gravitational center – the Sun. In this sense, below the Earth (or rather below Earth’s gravity well) we have Venus, Mercury and, at the very bottom, the Sun itself.
Does space have a floor?
Space has no floor. However, it’s not really an endless pit, either, because gravity doesn’t pull in one direction. It pulls toward objects that have mass.
Whats at the end of space?
Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end.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.
Is space flat or round?
As far as cosmologists can tell, space is almost perfectly flat. But what does this mean? The theory of general relativity, under which space itself can curve, allows for the universe to take one of three forms: flat like a sheet of paper, closed like a sphere, or open like a saddle.
Is space a finite?
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). The observable universe is centred on us.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I
How far above Earth is space?
62 miles
Yet the edge of space – or the point where we consider spacecraft and astronauts to have entered space, known as the Von Karman Line – is only 62 miles (100 kilometers) above sea level.
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).
Can you fall from space?
Similar to skydiving, space diving is the act of jumping from an aircraft or spacecraft in near space and falling towards Earth.However, Joseph Kittinger still holds the record for longest-duration free fall, at 4 minutes and 36 seconds, which he accomplished during his 1960 jump from 102,800 feet (31.3 km).
Can you go in any direction in space?
There is an up and down in space. “Down” is simply the direction gravity is pulling you, and “up” is just the opposite direction. Since there is gravity everywhere in space, there is also an up and down everywhere in space.If you are in space and the earth is the nearest astronomical object, you fall towards earth.
How flat is space?
The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4% margin of error.
How long until the universe ends?
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 the Higgs field is metastable.
What’s inside a black hole?
At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity. Just what the physics is like at this point in the black hole no-one can say for sure.
What existed before the universe?
The Universe has not existed forever. It was born. Around 13.82 billion years ago, matter, energy, space – and time – erupted into being in a fireball called the Big Bang. It expanded and, from the cooling debris, there congealed galaxies – islands of stars of which our Milky Way is one among about two trillion.
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen.
What is Edge of the universe?
The edge simply marks the dividing line between locations that earthlings can currently see and locations that we currently cannot. And although our observable universe has an edge, the universe as a whole is infinite and has no edge.
Is the 4th dimension time?
Physics > Space and Time
According to Einstein , you need to describe where you are not only in three-dimensional space* — length, width and height — but also in time . Time is the fourth dimension.
How will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze.Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
Why is space dark?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
