Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by uncrewed robotic space probes and human spaceflight.

/questions/1909/… writes to say > ... It's perfectly safe to orbit a black hole - as long as you don't cross the event horizon, you're fine ... A quick reminder that our Sun, and thus our entire solar system, orbits around a black-hole right now and we have a stable orbit.

Can something safely orbit a black hole?

Around larger black holes, tidal disruption doesn't happen until a star or planet is inside the event horizon, so anything outside is safe from that fate.

Can you rotate around a black hole?

Yes. All astronomical objects, including black holes, are formed by gravity pulling matter together. If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, then this spin rate will become greatly enhanced as the object collapses.

What is a white black hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

Why are spinning black holes special?

A rotating black hole can produce large amounts of energy at the expense of its rotational energy. This happens through the Penrose process in the black hole's ergosphere, an area just outside its event horizon.

How Close Can You Orbit A Black Hole?

Can you enter a black hole from any direction?

They can be created when two black holes rotate around each other or when a star orbits close to a black hole. Please be aware that black holes could be present in any direction in space.

Is it possible to orbit a black hole without falling?

It is possible to be near a black hole without falling into it, provided you move rapidly. This is similar to what happens in the solar system: Earth does not fall into the Sun because we move around it at a speed of some 67 thousand miles per hour.

Is a black hole hot or cold?

Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.

Is absolute zero Possible?

Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.

Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

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.

Can a warp drive escape a black hole?

If Alcubierre warp bubbles are physically possible, which is exceedingly unlikely, and if the equivalence principle is correct, you could definitely escape from a black hole in one, because there's nothing locally special about the event horizon.

Can anything escape a black hole?

According to Einstein's general theory of relativity, the gravity of a black hole is so intense that nothing can escape it.

How do we stop a black hole?

According to Einstein's theory, time and space, in a way, trade places inside the hole. Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.

Can humans create a black hole?

To study the phenomenon more closely, physicists in Israel managed to create a lab-grown, analogue black hole using some thousand atoms. This faux black hole exhibited all properties of a black hole in the state in which it is believed to exist in space.

What happens if you enter a wormhole?

Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel.

Have we ever sent a camera into a black hole?

According to Einstein's theory of relativity, there is no problem sending a camera (or anything else) into a black hole (meaning that it goes in past the horizon). Getting it (or its photographs) back out is an entirely different issue. This is not possible.

Where does a black hole take you to?

By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside. This, however, violates Einstein's general theory of relativity.

Can a tachyon escape a black hole?

Since the disturbance of a localized tachyon cannot spread faster than c, it therefore cannot escape the inside of a black hole's event horizon.

What can destroy a black hole?

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.

Could a FTL ship escape a black hole?

Even if you were somehow able to break the laws of physics and travel faster than the speed of light, you still couldn't get out of a black hole. The space within black holes is curved in on itself, and so there is no direction you can travel in to get out of the black hole.

Can time be bent?

So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.

Is time Travelling possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

What creates a white hole?

White holes are created when astrophysicists mathematically explore the environment around black holes, but pretend there's no mass within the event horizon. What happens when you have a black hole singularity with no mass? White holes are completely theoretical mathematical concepts.

How long is 1 minute in a black hole?
