When you shine a flashlight in to the sky does it ever come back or is it sucked into a black hole?

When you aim your flashlight at the sky, some of the light is scattered by dust or water vapor in the air. If you can see the beam, you're seeing SCATTERED light that has been reflected back to your eyes.
The beam of a flashlight isn't "collimated" - the light isn't focused into a very narrow beam. So the light spreads out. The light that spreads out and makes it through the atmosphere keeps going approximately straight out into space until it hits something. A meteor, a planet, a dust cloud, a black hole; whatever. If the light doesn't hit anything, it keeps going - forever.
However, even though the light from your flashlight is traveling into space at the speed of light, so is the light from every OTHER flashlight, street light, car headlight, reflected starlight and moonlight - all mixed in together. So even though your light will go on forever, "your" light is probably indistinguishable from all the rest of the light from Earth.
If you aim your flashlight at the Moon, then some tiny fraction of the moonlight that you see three seconds later is light from your flashlight, reflected back to you. And to everyone else on Earth who is looking at the Moon right then.

How close can you get to a black without getting sucked in?
It's extremely unlikely that you'll ever find yourself in this situation. However, once you cross the event horizon of a black hole, the escape velocity of the singularity exceeds the speed of light, so past that point, you're never coming back.
When was Black Is Back created?
Black Is Back was created in 2007.
What would happen if you put both batteries in backward in a two cell flashlight?
Nothing would happen, the flashlight simply wouldn't work. Switch the batteries back around and it will work. This is purely because the contacts don't line up properly. A normal incandescent lamp will work either way round. A modern LED flashlight however is polarity sensitive.
When does chemical change happen on a flashlight to produce electricity?
It happens when you turn on the flashlight and a circuit is created through the batteries, through the light filament, back down the outside of the batteries to the end of the batteries, etc. Switching off the flashlight breaks the circuit, curtails the chemical reaction in the batteries, and the light goes out.
How did Stephen Hawking discover that black holes emit heat?
He stated that Black Holes emit heat because they are nothing more than collapsed stars that suck in particles and then they themselves are destroyed. After doing so the object that was sucked into the black hole is sent back into its own universe, instead of being transported to a parallel universe. Since energy is needed for these processes it is necessary for light and Light=Heat. It all has to do with light wavelength and the conversation of matter.
When you shine a flashlight at a mirror does it come back at you?
Yes, it does.
Can light waves be absorbed?
Sure. Shine a flashlight on a piece of black satin or black construction paper, and watch the intensity of the blinding glare that's reflected back.
Can you make it back if you get sucked into a black hole?
no you can not
When you shine a flashlight at a mirror the ray of light that shines back at you is the ray of incidence?
This is FALSE. The incident wave "happens" when you shine the light AT the mirror. THe light that comes back is called the reflected wave.
If you shine a flashlight at a mirror what does it prove?
When you shine a flashlight at a mirror it proves that you are able to turn the flashlight on. The reflection of that light can be used to demonstrate some basic principles of optics, such as that the angle of incidence equals the angle of reflection. It proves that the flashlight is in working order, that you are able to direct the light toward the mirror, that the light is reflected by the material at the back of the mirror, that the mirror itself is opaque, and that you have access to a mirror and a flashlight.
How painful is being sucked into a black hole?
nobody knows because when you get sucked in you never come back haha :)
Can you come back from being sucked into a black hole?
No, it tears you apart/ "destroys you"
What would happen if you sent a robot into a black hole?
It would get sucked into it, and would never get back out
What is a surgical shine job?
A Surgical shine job is a procedure where one gets a reflective material surgically implanted on the iris. This allows light to enter the eye and reflect back outwards creating a sort of built in flashlight. Similar to that of cats.
How do you defeat the sharks on astro nights?
Do you know where the black hole is shoot at one of the sharks and lead them to the black hole but stay around the black hole and the shark get's sucked in.Do it one at a time the ones that dont get sucked in teleport back to the planet.Oh and by the way im a kid!
How does a shake up flashlight work?
It uses your energy, a very strong magnet, and the principles of induction. Shake it to "power it up". Shaking the flashlight causes a very strong magnet to pass back and forth inside a wire coil. The magnet's movements cause the light's capacitor to be charged, which causes the light to shine.
If something ges sucked into a black hole will it come out of the other end?
The current theory by Stephen Hawking is that black holes slowly "evaporate" over time; so if you are sucked into a black hole you are crushed to microscopic size and held in the black hole; and then billions of years later the elemental particles elements that were you are released back into space to be re-used for something else.
