What if some of these teachings were wrong? I do not want to really engage in a debate about who is right or wrong, but common sense ''says'' to me that things do happen all at once . In example, it is now on Earth and it is now on the Moon, although the observer may measure time differently , now is always now . Different events are in my opinion just actions in different geometrical positions happening now . A delay in seeing the event is not the same thing as time dividing events. It is the space and distance that divides the events, time divides the synchronous of seeing events. Would you disagree with my opinion? ! Moderator Note OK, so you asked what science is to make it seem like you wanted to discuss this, but then you switched over to telling us what you think science is, which is speculative in nature, and doesn't belong in our mainstream sections anymore. I'm going to move this where you can defend your extraordinary claims, hopefully with more than just your incredulity. Please use evidence to support your claims.

I accept your challenge on defending that which I said. The supposed centre of the Universe is the exact same age as the ''outer'' Universe, expanding since the big bang. Space divides the supposed centre and ''outer'' of the observable Universe. Time is not a thing between masses, space that is occupied by electromagnetic radiation is between masses. Would anyone disagree with that honesty?

I like your answer best of all of these. Mainly because it's not just a boring dictionary paste up or memorization. And two, cuz it admits that science and more accurately scientists are usually biased to some degree. Thus, the best science is done with the least degree of bias, assumptions, or personal agenda. Every scientist, since he is a flawed human being, is best with emotions, likes, dislikes, as well as a real....if perhaps covert or subconscious.... preference in his mind how he WANTS the experiment or observation to turn out. Thus....the best of them recognize this and don't let it affect their work. Again...great answer! Thanks. I might use it in the future, giving you full credit!

Quote Thus....the best of them recognize this and don't let it affect their work. The important point is the methods used to eliminate biases. That is where good experimental design comes in. I heard a great example some time ago from stroke research - unfortunately, I can't remember the details but the key bit was along the lines: "we knew this couldn't possibly have any effect but knew we should include a test to eliminate it anyway." To their surprise this "impossible" effect turned out to be crucial and resulted in improved stroke treatment.

Wow! where to start.....Let me start with the possibility of Einstein being wrong...He certainly was wrong on occasions, such as in the beginning rejecting what GR had told him, re the universe being a static quality rather then a dynamic one: Reason he did that? He was following the accepted "common sense" beliefs of the day, which soon afterwards was shown to be in error by the observational evidence of a comrade named Edward Hubble....which then answers your second faux pas. Your third error was claiming Einstein simply had an opinion. This actually shows that you are totally unaware of what science is, what the scientific method entails, and of course what a scientific theory is. Your fourth error was your apparent insistence on a universal now....do you also claim that the speed of light is instantaneous? Because that is the only way you can have a universal now....Einstein and relativity shows us that beyond any shadow of doubt. So in answer to your final question, yes I disagree with your opinion, simply because observational and experimental evidence show indisputably that you are wrong. Opinions are not science. 4 hours ago, Vril said: How can any experiment prove or show there is no Universal now? Please name one experiment? The finite speed of light. eg: You go out tonight and gaze at Alpha Centauri system...in fact due to the finite speed of light you are seeing the light that left it 4.3 years ago because it is 4.3 L/years away. You do not see it now.

Quote Space, in everyday language, is something that we all know. It is measured in the three dimensions of distance: length, width, and height. In modern physics, space is a "boundless four-dimensional continuum" known as spacetime. Disagreement exists about whether it is an entity (something that actually exists). I disagree with you and propose that space and space-time are two separate independent things and you failed to understand what space-time is comparative to space. 27 minutes ago, beecee said: The finite speed of light. eg: You go out tonight and gaze at Alpha Centauri system...in fact due to the finite speed of light you are seeing the light that left it 4.3 years ago because it is 4.3 L/years away.

Strange Posted May 12, 2018 Posted May 12, 2018 32 minutes ago, Vril said: How can any experiment prove or show there is no Universal now? You need to start a separate thread where you learn the basic concepts of relativity, and in particular, the concept of relativity of relativity of simultaneity. This shows that different observers measure time and space differently. The most obvious example that there is no universal "now" is the fact that different observers may disagree about whether two events are simultaneous or not. They might even disagree about the ordering of the events. There is lots of experimental evidence for SR. If you think the evidence is incorrect, then explain why. 1 minute ago, Vril said: Space-time , 3 dimensional vector lines and time is a coordinate system. A mathematical process to measure space. Space is independent of space-time. As I said, that makes no sense. Space is just three of the four dimensions of space-time. So you are saying space is independent of space?

Maths is not the space , space is space .
