Is there an up and down in deep space?

Since there is gravity everywhere in space, there is also an up and down everywhere in space. Gravity is a centrally attractive force, so “going down” means falling or being pulled towards the center of the nearest massive object.

How do we know what’s up in space?

Things in space which release or reflect light, like stars or planets, can be seen either with the naked eye or with telescopes. By looking at that light, scientists can either directly tell where objects in space are, or at least can make deductions about their locations.

How do you know if you’re upside down in space?

The signals from an astronaut’s body in space go haywire in weightlessness. The inner ear reports that it is falling, but the eyes show that nothing is moving. As fluid shifts to the head, the brain usually interprets this extra pressure as a sign it is upside down – but in space there is no up or down.

Do you float or fall in space?

In space, astronauts do not walk on the floor like people on Earth do. They float around inside their spacecraft. That is because of microgravity. Microgravity is when things seem to be weightless.

How far up does space go?

100 km
The Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping. The framework for international space law was established by the Outer Space Treaty, which entered into force on 10 October 1967.

Can someone hear you scream in space?

So, Alien has it right; while it’s not strictly true that sound waves can’t travel through space, it is true that humans would not be able to hear those sounds. Scream all you want, no one is hear you. Radio waves can travel through space because they’re electromagnetic, not mechanical, and can travel through a vacuum.

What happens when you go up and down in space?

If earth is the closest large body, down is always towards the center of the earth and up is always away from the center of the earth. Nothing magical happens if you are leave earth’s surface and board the International Space Station: down is still in the same direction.
