A telegram
~The telegraph was the starting point for the science behind modern communication devices like the telephone and fax machine.~The telegraph was the first device that allowed information to travel over a distance without being physically transported by a person.~The telegraph was the first machine used to broadcast news using sound.~The first message sent on the telegraph was transatlantic, proving that a message could be sent over a long distance without a human being needed to transport it.
The first wireless message was sent by Guglielmo Marconi in 1895. He successfully transmitted signals over a distance of about one and a half miles, marking a significant milestone in the development of radio communication. Marconi's work laid the foundation for modern wireless technology and communication systems.

The time for the message to reach them should equal the speed of the message divided by the distance the message had to travel. The message would have been a radio wave so travelled at the speed of light, 300,000,000 meters per second. So all you need to know is the distance it had to travel. That will be the distance from the surface of the Earth to the Moon (in metres) minus 10,600,000.
The first message sent by Samuel Morse on May 24, 1844, was "What hath God wrought." This phrase was transmitted via telegraph from Washington, D.C., to Baltimore, Maryland. It marked a significant milestone in the development of long-distance communication and showcased the potential of Morse's invention. The message was chosen from a biblical verse, reflecting the profound impact of the technology.
because the message was no sent.
Ooh, so close. Now we have to guess what the message was sent through. A message sent through a telegraph is a wire. A message sent through a chat room or a blog is a post. A message sent through a letter is mail.
Regardless of how or why you sent a text message, once it is sent from your phone it is billed as a sent text message.
No, you can't. Once a message is sent, it can't be unsent.
Yes, you can pass a message to someone else that was sent to you, as long as you have permission from the original sender or if the message is intended to be shared. It's important to respect the sender's privacy and the context of the message. Ensure that the content is appropriate for the recipient and that you convey it accurately.
