Question: Is Space A Physical Thing?

Is space an object?

Space is the boundless three-dimensional extent in which objects and events have relative position and direction.

Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime..

Can space be created?

No. And nor is energy. Energy is the one thing we can neither create nor destroy, and it seems to be intimately related to what space is. But nevertheless the stress-ball does get bigger as the pressure reduces, so it’s reasonable to say space is “created”.

What is example of space?

Space is the three-dimensional area around you, including the universe. An example of space is where stars and planets exist. An example of space is where Ham the Chimp travelled for 16 minutes and 39 seconds in 1961 during the first space flight in one of the Project Mercury capsules named MR-2.

What is physical space?

The physical space is simply the unlimited expanse of the universe, in which all material objects are located and all phenomena occur. … Two others are the space of classical mechanics, assumed to be controlled by Newton’s laws of motion, and the four-dimensional spatiotemporal world of the theory of relativity.

Is space a liquid?

(Inside Science) — Spacetime is a somewhat slippery concept — Einstein described the universe in four dimensions, combining the well-known three dimensions of space with time. Physicists now suggest that spacetime may itself be a fluid, a very slippery type known as a superfluid.

Can you swim in space?

2 Answers. You can sort of swim, but it would be very slow. The viscosity of air vs water is very low. Therefore the ‘scoop’ your hands or feet can get of the fluid, to propel it, and thus move you around would need to be much higher.

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 …

Are we living underwater?

Living underwater is actually possible, and you could be moving to an underwater city in the near future. The idea of humans living underwater may not be as crazy as you think. An idea once reserved for video games or science fiction, underwater cities may be a viable solution for humanity in the distant future.

Why is it called space?

The English word space originates from Latin word for expanse – spatium (also written spacium in Medieval Latin), and later French word espace , through the use of which English variant space was formed. Of incorporeal speed, her warmth and light; Speed, to describe whose swiftness number fails.

What is space in simple words?

Space, also known as outer space, is the near-vacuum between celestial bodies. It is where everything (all of the planets, stars, galaxies and other objects) is found. On Earth, space begins at the Kármán line (100 km above sea level). This is where Earth’s atmosphere is said to stop and outer space begins.

How is space created?

Around 13.8 billion years ago, all the matter in the Universe emerged from a single, minute point, or singularity, in a violent burst. This expanded at an astonishingly high rate and temperature, doubling in size every 10-34 seconds, creating space as it rapidly inflated.

Does water freeze in space?

So the freezing process would be incredibly slow, unless there were some way to expose every water molecule individually to the vacuum of space itself. … So that’s what happens: first the water boils, and then the very fine mist that it boils away into freezes, giving rise to a tenuous, fine network of ice crystals.

Is the universe made of water?

The chemical elements in water, hydrogen and oxygen, are some of the most abundant elements in the universe. Astronomers see the signature of water in giant molecular clouds between the stars, in disks of material that represent newborn planetary systems, and in the atmospheres of giant planets orbiting other stars.

Does outer space exist?

From the perspective of an Earthling, outer space is a zone that occurs about 100 kilometers (60 miles) above the planet, where there is no appreciable air to breathe or to scatter light.

Can you breathe in space?

But inside the International Space Station (ISS), the American astronauts and Russian cosmonauts do breathe air almost identical to the stuff we breathe down here on planet Earth – same pressure and about 80 per cent nitrogen and 20 per cent oxygen. … It turns out they get it by ‘splitting’ H2O with electricity.
