The speed of light is not a limit. Einstein is completely wrong.
The speed of light is not a constant.

That's what I heard Rupert Sheldrake say, that the speed of light may well vary. Well, I only know this much, that sunlight takes about eight minutes to reach the earth. From this knowledge I can build up an imagination what this means for farther away cosmological objects. If it's not always exact in its speed, I can live with that.

There is almost instantaneous communication through the universe.

I don't rule that out. The question is what form of communication you mean by that and how I mean it and who communicates with whom or what communicates with what.

We cannot leave the earth.
We are a part of the earth.
This is exactly what happens to astronauts who stay in "space" for a long time. They actually dissolve. It is like taking a plant out of the earth.

I can relate to that.

We will have to learn to develop an earth like field around us before we can leave. And we do not even believe in these "fields" yet. All spooky woo woo.

Well, whether I believe in it or not can't make me the object of your displeasure, can it? Unless you are saying that I MUST believe in it.
I find the idea of surrounding myself with an Earth field fascinating, in fact I once wrote an SF story where the beings who met created just such a thing to make interstellar acquaintances in the first place.
But what do you mean when you say "we" have to learn to develop an earthlike field?

Free energy exists at every point in the universe.
There is no energy cost thingy in computing space travel.

I don't understand what you mean by that. Can you specify or give examples?

Travelling across space costs time.
Not how you think of time as. It is part of a right hand rule for aether.
An example, it will cost half of your lifespan to teleport to earth. The time taken to travel here is almost instantaneous.

From where teleport? Whose lifespan? You mean to dematerialize and materialize a body?

I am sorry, almost everything taught to you in science class is wrong.
Not a little wrong, like the theory needs to be tweaked a little bit, but complete wrong.
Like, the aether does exist Michelson & Morley...

I am not a natural scientist and have no training in it. I have little knowledge of the basics of physics or chemistry or mathematics at all. What theory are you talking about anyway, because you are far too vague for me to understand you.

What do you mean by aether? There is space between cosmological bodies. This space is subject to certain laws that we have found out. Are you saying that all these laws are wrong? That may be so, because science lives from the falsification of its own products. Something is "right" (accepted) until it is not. But you sound as if this is an impertinence. But it is normal that it is like that, isn't it?
