Is the Universe's Expansion Controlled by Gravity from a Black Hole?

In summary, the conversation discussed the concept of time and its relationship to the expanding universe. It was suggested that time is controlled by the gravity generated by a black hole, with stronger gravity causing the universe to expand faster and time to speed up. However, this idea was deemed nonsensical and not supported by real physics. The conversation also reminded the individual that this is a place for asking questions and receiving answers from experts, not for sharing personal theories or ideas.

What we experience as time is just the universe expanding into essentially nothing and the universe continues to speed up because literally nothing is stopping the big bang because the big bang is an exploding black hole that sucked in everything to begin with or perhaps the black hole is so powerful that it's still sucking everything up causing a constant explosion and the universe just appears to be expanding because its getting sucked up the by the black hole at the same rate it's exploding (but speeding up) so time is controlled by the gravity generated by the black hole? And the stronger the gravity the faster the universe expands speeding time up and (the movement of) space?

That's a very long word salad sentence..

pure and unadulterated BS. You should read some real physics.

Time is not well defined, it is a measured value where the universe serves as our clock. Ascribing gravity the role of 'clock' does not resolve this issue.

000Tommy, Welcome to Physics Forums.

This is a place for anyone to ask a question about Astronomy (or other subjects) and to receive answers/explanations from experts who are well-educated in their fields.

This is NOT a place for such posts as you have written above. What is your question? Your first 100 words, followed by a question mark is not a question. It is a rambling mixture of words that make no sense whatever. This is NOT a place to try to imagine some new theory or idea, either (if that's what you tried).

Now, seriously, if you know some things about Astronomy or Astrophysics, and want to learn more, then please write out your questions in clear English. Be sure to limit each question to only ONE subject. You will be surprised how much you can learn about science once you learn how to use this valuable resource.
 

1. What does "make sense" mean in a scientific context?

The phrase "make sense" in science refers to whether a particular theory, hypothesis, or experiment aligns with established scientific knowledge and principles. Essentially, it means if something is logical, consistent, and supported by evidence.

2. How do scientists determine if something makes sense?

Scientists use a variety of methods to determine if something makes sense, such as conducting experiments, analyzing data, and comparing results to existing knowledge. They also use critical thinking and logic to evaluate the consistency and plausibility of a theory or hypothesis.

3. Can something make sense to one scientist but not to another?

Yes, it is possible for a theory or hypothesis to make sense to one scientist but not to another. This can be due to differences in background knowledge, personal biases, or the interpretation of data. However, the ultimate goal of science is to reach a consensus based on evidence and logical reasoning.

4. What should I do if I don't understand something in science?

If you don't understand something in science, it is important to ask questions and seek clarification from reliable sources, such as your teacher or a scientist in the field. It can also be helpful to do further research and educate yourself on the topic. Remember, it's okay not to understand everything, but it's crucial to remain curious and open-minded.

5. Is it possible for science to not make sense?

Yes, there are instances where scientific concepts may not make sense or seem counterintuitive. This can be due to the complexity of the topic, limited understanding or technology, or the need for further research. However, it is important to trust in the scientific method and continue to question and seek answers to further our understanding of the world.
