Answer:
True!
Explanation:
A political boundary is an imaginary line separating one political unit, such as a country or state, from another. Sometimes these align with a natural geographic feature like a river to form a border or barrier between nations. Occasionally, two countries may contest where a particular border is drawn.
The North American Union (NAU) is a theoretical economic and political union of Canada, Mexico, and the United States. The concept is loosely based on the European Union, occasionally including a common currency called the Amero or the North American Dollar. A union of the North American continent, sometimes extending to Central and South America, has been the subject of academic concepts for over a century, as well as becoming a common trope in science fiction. One reason for the difficulty in realizing the concept is that individual developments in each region have failed to prioritize a larger union.
Some form of union has been discussed or proposed in academic, business, and political circles for decades. However, government officials from all three nations say there are no plans to create a North American Union and that no agreement to do so has been signed. The formation of a North American Union has been the subject of various conspiracy theories
Answer:
- the first direct detection of gravitational waves came in 2015
- gravitational waves are predicted to travel through space at the speed of light
- the existence of gravitational waves is predicted by Einstein's general theory of relativity
Explanation:
The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.
These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.
These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.
