How is space described?

How is space described?

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.

What are some cool things in space?

  • Space is completely silent. ...
  • There is an uncountable number of stars in the known universe. ...
  • The Apollo astronauts' footprints on the moon will probably stay there for at least 100 million years. ...
  • 99 percent of our solar system's mass is the sun.

Can a star turn into a planet?

Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. ... Despite beginning life as a star, a brown dwarf quickly uses up its heavy hydrogen, goes dark, cools, and spends the rest of its life as a planet.

What exactly is a black hole?

A black hole is an area of space with a gravitational field so strong that nothing, not even light, can escape it. That's why black holes appear black. In some cases, black holes are former massive stars that have been crushed to an extreme density during supernova explosions.

Could a human survive a black hole?

Thus, the person would pass through the event horizon unaffected, not be stretched into a long, thin noodle, survive and float painlessly past the black hole's horizon. A person falling into a supermassive black hole would likely survive.

What happens if you go inside a black hole?

Of course, no matter what type of black hole you fall into, you're ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you're done. There's no getting out.

Can you see a black hole?

You can 'see' the closest known black hole to Earth with the naked eye. There is a black hole in our backyard. Astronomers have found the closest black hole yet at just 1000 light years from Earth, close enough to see the stars that orbit it without a telescope.

Will a black hole ever hit Earth?

There are no black holes close enough to Earth to affect us. The closest black hole to Earth that we know of is named V616 Monocerotis. It is also known as A0620-00. This black hole is 6.

Is there a black hole near Earth?

The supermassive black hole hiding in the center of our galaxy is much closer to Earth, about 2,000 light-years closer, than scientists thought, according to new research out of Japan. Not only that but our solar system is moving faster than thought as it orbits this galactic center.

Can CERN create a black hole?

The LHC will not generate black holes in the cosmological sense. However, some theories suggest that the formation of tiny 'quantum' black holes may be possible.

What is the God particle theory?

In 2012, scientists confirmed the detection of the long-sought Higgs boson, also known by its nickname the "God particle," at the Large Hadron Collider (LHC), the most powerful particle accelerator on the planet. This particle helps give mass to all elementary particles that have mass, such as electrons and protons.

What is a black hole made of?

two neutron stars can collide, creating an event horizon and leading to a black hole, and a dense collection of matter, either in the form of gas or a star, can directly collapse, leading to a black hole.

Where is the closest black hole?

Sagittarius A

Where do things go after a black hole?

It can never leave that region. For all practical purposes the matter has disappeared from the universe. Once inside the black hole's event horizon, matter will be torn apart into its smallest subatomic components and eventually be squeezed into the singularity.

Why there is no light in space?

Around Earth and the inner solar system, for example, space is filled with dust particles that get lit up by the sun, creating a diffuse glow over the entire sky. But that dust isn't a problem out where New Horizons is. Plus, out there, the sunlight is much weaker.
