If something travels through the space, it's the energy. The electromagnetic wave including visible light, Gamma rays and others and everything is energy. You can find the energy of a photon of a electromagnetic wave using E=hf .
And also explosions like supernovae carries energy too. Energy can not be destroyed. So the energy of stars has also been carried by them. You'll wonder to know that the atoms you're made have came from only a supernovae. So Only thing that can travel through the space is energy.
Electromagnetic energy, such as light and radio waves, can travel through empty space or through matter. This type of energy does not require a medium to propagate and can travel vast distances through the vacuum of space.
Radiation energy
No
Electromagnetic energy, such as light and other forms of radiation, can travel through a vacuum in space due to its ability to propagate without a medium.
No, electromagnetic energy can travel through a vacuum. It propagates through space as electric and magnetic fields that oscillate in a perpendicular fashion.
Yes it can
All radiant energy travels through space in the form of electromagnetic waves.
Those two descriptions are not mutually exclusive, and in fact, electromagnetic waves do both.
Energy can be transferred through empty space by radiation. Joule is the SI unit of energy.
Electromagnetic energy travels through space in the form of waves, known as electromagnetic waves. These waves consist of electric and magnetic fields that oscillate perpendicular to each other as they propagate through space. The energy is carried by these waves and can travel through a vacuum, such as outer space, without the need for a medium.
Gamma Rays will travel as long as they have energy
(a) Electromagnetic waves; that includes light. (b) Gravity waves.
