Can ELF (extremely low frequency) radio waves travel indefinitely in universe (even in plasma zones and cosmic background noise)?
Can ELF (extremely low frequency) radio waves travel in universe (even in plasma zones) and farther until reaching the farthest zones in universe?
Is it possible for objects in the 100 to 10.000 Kelvin temperature range to emit ELF waves in addition to visible light? Can there be potentially habitable worlds near the core of the galaxy or is the light and radiation too strong? What is the farthest thing in the solar system confirmed? How long will it take for the cosmic microwave radiation to pass us? How do radio waves work in space? Will a Magnetar Shockwave hit earth in 9-10 days? Radio signals of one sort or another have been broadcast for nearly 100 years. What level of signal from Earth could accurately be received from an interstellar observer light years away? How long does it take for a radio signal from Earth to reach the moon? Is there any maximum frequency of electromagnetic waves? What would happen if a gamma ray burst from a supernova hit Earth from differing distances? How far away from a planet could we theoretically see its surface? What is the furthest into the past that astronomers can currently see? Will we be able to see even further as technology advances? How do radio waves travel? How far have humans travelled in space? Can we see planets with radio telescopes? Can gravitational waves be used for communication across the universe just as radio waves are used for high-speed communication? How can the far reaches of the unobservable universe be expanding at faster than the speed of light? Can any sound be heard in outer space? If not, why? Could we ever reach the non-observable universe using time dilation in the same way we could reach Andromeda? How long would it take a sound (like a radio wave) to travel 1 light year? What are birkland currents and are they any important for our further understanding of the universe? If the sun was a pebble how far would it be from pluto? Does gravity act at an infinite distance? How far can sunlight travel in space? If radiowaves are reflected from objects (i.e planets) and they can penetrate a bit in the surface, we could image the subsurface right? Can gravity waves be used to send messages across spacetime? Is there any cosmic bodies that are going to hit The Earth today? And where will it land? (if yes) and at what time? Could Planck's ladder be applied on a universal or even galactic scale? Can we hear anything in space? How can Voyager send a signal strong enough for us to receive, in spite of its enormous distance from us?
