shyt is typical cac shyt. let’s transmit a radio signal that might - even in the remote off chance - be picked up by a civilization whose designs on other worlds aren’t friendly.

stephen hawking said it was the height of arrogance and completely irresponsible to do this.
Yep because we aren’t ready for some random malevolent force to arrive here

Read The 3 Body Problem.

We don't want them problems

It's nothing. It's just the astronaut they sent out on a life long mission in 1987, sending a message. He sent it in 2005 and they finally just received it here on earth

Eventually, we're going to want to expand the World Wide Web across the galaxy, and NASA just demonstrated a key piece of tech that could help, beaming messages via laser across a distance of almost 16 million kilometers or 10 million miles..

That's about 40 times farther than the Moon is from Earth, and it's the first time that optical communications have been sent across such a distance.

Traditionally, we use radio waves to talk to distant spacecraft – but higher frequencies of light, such as near infrared, offer an increase in bandwidth and therefore a huge boost in data speed.

If we're going to eventually be able to send high-definition video messages to and from Mars without a significant delay, then this is a step towards the tech we need.

The test is part of NASA's Deep Space Optical Communications (DSOC) experiment, and the successful establishment of the comms link is known as 'first light'.

Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity's next giant leap," says Trudy Kortes, who is director of Technology Demonstrations at NASA Headquarters.

Nice
I believe the next step is light teleportation that would be a game changer
