They did. Look up the Baghdad batteries.

A virus made from nanotechnology.

If you can measure the size of the universe then you can also measure the time it took the light to loop around and thus measuring its speed.

I asked a very similar question in this thread https://www.physicsforums.com/threads/measuring-the-one-way-speed-of-light.995539/page-5#post-6423799 and one user pointed out that it's no different than using mirrors to bounce that light back to you.

From what I understand that would not be a one way measurement of light. You take a spaceship and a measuring tape and loop that measuring tape around the universe.

I suppose you can do it by encoding a message on that beam of light.

Suppose we're in a closed and non-expanding universe. You shine a beam of light in one direction such that it circumnavigates the universe and returns to its starting point from the other side. Now you put a detector at this starting point. Would this be a one way measurement of the speed of...

Can't you theoretically measure the one way speed of light using a black hole? You shoot a beam of light at the black hole at a geodesic path that curves the light beam back to your detector. Also if the speed of light is directional wouldn't we see this in the CMB where the universe will...

We do have something called METI https://en.wikipedia.org/wiki/METI_(Messaging_Extraterrestrial_Intelligence)

I can say the same about your previous comment.

Planck's temperature has a specific unit of 1.417×10^32 kelvin

There is. Look up Planck's temperature.

We have entire professions dedicated to studying ants. And we would probably talk to them if we could.

Fraser Cain and PBS Space Time is pretty good. Youtube videos are almost never a good source for citations unless it's a University lecture.

Where are you getting all these nonsense info from?
