Hello,it isevident that we are not alone Inside our universal sphere.Astrobiology is fascinating.There are a lot of civilizations even when we consider the number of galaxies.Some less Evolved ,others more.I beleive strongly that our actual waves Under our special relativity are not sufficient.We cannot communicate at a kind of present due to our limits of scales.We can only have a past message.If civilizations send messages, if they have the same step than us ,so we can indeed have waves.But it...

If we could change the speed of light and gravitational constants, c and G, superluminal travel would be much easier.

It is very frustrating this problem about the linear velocity of spaceships.

Already that c is not sufficient to visit and travel Inside our Milky way.We are at 27000 light years of the central BH and the lenght is 100000 light years.

It is absolutely neccesary to go fasterthan c.But it is not possible with bosons , so we must focus on gravitons produced by cosmological BH sphères.The correlated entropy is relevant.In this line of reasoning it is possible to travel between...
