All objects in the universe give off radio waves or pulsars?
I translate ‘pulsars’ as meaning ‘pulses of something’ other than radio waves, like pulses of energy or electromagnetic charges/vibration/frequencies. And I don’t believe that there is anything in the universe that does not have a force behind it. I believe the radio waves that any stellar object gives off is the result of the the dischord of the energy pushing the object and the object itself; if the object wasn’t there, there wouldn’t be any radio waves. The same thing with my translation of ‘pulsars.’ There is energy and then there’s objects. Einstein said, ‘Any object set in motion will stay in motion unless acted upon by an outside force.’ In a universe with one object there is no ouside force besides the gravity of its own being and that gravity and the movement of that object through space gives off a gravitational wave. But, if your question asks whether pulsars are the only thing that gives off radio waves, the answer is no.
Actually, I will answer Dark_hellbent_king2. Yes, human being give radio waves. It’s only that we generally think of a certain frequency when we talk about “radio.” Light, radio waves and x-rays are all different frequencies of the electro-magnetic force. If you look at a person trough an infrared camera in the dark, you will see that body heat is actually a ‘radio wave’ since the infra-red is just slighly over the light frequencies. As an illustration, I read that astronomers have discovered a big ‘hole’ in the universe. Its radius is nearly one billion lightyear! No, it is not a black hole or anything else. Yes, they know it is empty because the huge region is about half a degree Kelvin under the temperature of the rest of the universe. So, there you are: matter gives energy in form of heat: also an electro-magnetic energy.
If the question is a fill in the blank (“All objects in the universe give off _____”) and the choices are: A. Radio Waves B. Pulsars Then either the question is in error or the choices given are. I think if it is in fact one of the choices, then it is most likely radio waves, as all objects give off radiation, but I think that it is just thermal radiation and not electromagnetic.
No. All objects within the Universe do not give off radio waves. The Moon which circles the Earth does not give off any radio waves, for example. The Sun gives off astouinding amounts of radiation which is spread across a very wide spectrum which includes the radio spectrum. This radiation is often classified as noise, if you want to get down to the simple terms. The noise comes from the huge nuclear fusion process going on inside the Sun. Pulsars are dead stars which have collapsed upon themselves and formed extremely dense chunks of matter. Most pulsars are estimated to be no larger than an average size city on the Earth. HOWEVER, the nuclear fusion process which was quite active when the star was young and big has now been compressed down into a very small area and continues to emit fantastic amounts of radiation. In the case of pulsars, the radiation tends to be transmitted out of the regions which are called the Poles of the object (North Pole, and South Pole.
