Yes, matter causes gravity.

Time is a phenomenon. I don't think anyone in the world ever said that matter is a phenomenon, except for you in your reply. Matter is both real and can be said to be self-based. We can simply prove a table is real by taking a hammer to the table; we cannot take a hammer to time and slam it (nor can we create a temporal hammer and slam time with it). The foundation of the material universe is matter; it is our solid ground.

So, my apologies if you misunderstood me. I do not see where I created that misunderstanding, but we communicate via language, and I am not perfect, so please point me to where I gave you the impression that matter is a phenomenon.

Time and space are phenomena. Matter and energy are not, even though energy is also quite difficult to comprehend with our human mind.

In Science, I see scientists throw everything in a bag and say that all started out simultaneously. That is misguided. We only have evidence that matter started to appear. We say correctly that matter is a result.

We do not have any data about the beginning of time, space or energy. So, good scientists should stick to what we have: data about the beginning of matter. That is what we have, not the other parts.

By throwing all in one bag, a path is taken that does not exist in science. It is a religious path to say that a unified field of forces is possible when based on a single field; one needs two levels to show their relationships. I can talk about that more, but let's first see if we can straighten out the misunderstandings among ourselves.

Thank you, bkuelhorn for this reply. I like that you are trying to communicate with me on this.
