Universe doesn't equal Time travel

In summary, the conversation discusses various theories about the beginning and expansion of the universe and the concept of time travel. One person believes that the universe does not have time in its equation but only speed, while another brings up the idea of multiverses and how they relate to time travel. The conversation ends with a compliment to the theory proposed by one of the participants.

I have a theory, please correct me if I'm wrong.

What if the big bang didn't start the universe from expanding? If we were speed up to the rate the universe is accelerating in, where would we be? How did it start?

Well I have an answer, I am not sure about the big bang theory being correct, but what I'm having difficulty is that the shape and size of how it blew up. I think the universe doesn't have time in it's equation, though it has a speed.

Now think about this, if you were to time travel back in time trying to fix a problem in the past (Like telling yourself not to ask a certain person to marry you, because it work out in the future). Where will you turn up if you were go back to the present?

The Answer: The Universe isn't the only universe, like a molecule isn't the only molecule (There are many others). So, if you time travel, your not actually time traveling your Universe travelling.

OK, let's see if I can get this in before this thread gets locked... (pet theories not allowed)

You seem to have several unrelated ideas here, one about expansion of the universe and another about time travel.

The *definition* of speed is distance over time.

Well done! This is actually one of the proposed ways of averting time travel pardoxes.

I disagree about how you could be traveling through time in the multiverse because you can't do this all at one time. If your universe is one but many universes chances are each universe operates differently than others. So if you were to travel back 500 years in this time it won't make a difference on the outside I don't think.

While I'm a believer in the multiverse theory (well, as an atheist I feel obliged to believe in something), there's one aspect of the crossing of timelines equating to time travel that has never made sense to me. As far as I can tell, all 'phases' of the multiverse are supposed to be infinitesimally different from those adjacent to them. That would mean that they all started at the same time, and are aging at the same rate. In order to affect the past of one, therefore, you would still have to travel backward into its time. It seems to me that the only way you could really go back in time by crossing universe boundaries would be if you cross laterally into one that is younger than the one that you start in. Anybody care to sort this out for me?

Universe Travelling

I believe your theory. You have clearly thought this out very thoroughly. I'm 12 years old and it is very common for any child this age younger or older to be thinking about time travel. I always wondered why it was just TIME travel, and the consepts of time, but then the consepts of the universe. If it was Universe travelling, that would make a little bit more sense. The faster the universe goes, the further ahead in years/time we would be...if it were going in the opposite direction, we may be back in the stoneage. (lol.) When I was about 6, I wanted to go back in time, so I created a type of blue chart. (Although, I was six, therefore, it was barely recognizeable as a blue chart.) Anyhow, scientists have now found a molecule thing that is related with time traveling "universe travelling". If I had that then, I would have built a "time machine". Or would have gotten considerably close. I still long to make a time machine, and will succeed someday. I think your theory is Brilliant, brilliant I say. =^-^=

What is the difference between the universe and time travel?

The universe refers to all matter, energy, and space that exists in the physical world. Time travel, on the other hand, is the concept of moving through time to the past or future.

Can we travel through time within our own universe?

The current understanding of physics suggests that traveling through time within our own universe is not possible. The laws of physics, particularly the second law of thermodynamics, make it highly unlikely for time travel to occur.

Why is time travel often portrayed in science fiction?

Time travel has always been a popular topic in science fiction because it allows for the exploration of alternate realities and the possibility of changing the course of history. However, the actual scientific feasibility of time travel remains uncertain.

Are there any scientific theories that support the idea of time travel?

There are some theories, such as Einstein's theory of relativity and the concept of wormholes, that suggest the possibility of time travel. However, these theories are still being studied and have not been proven to be feasible.

What are the potential consequences of time travel?

The consequences of time travel, if it were possible, are unknown and highly speculative. It is possible that altering the past could have unforeseen and potentially dangerous consequences on the present and future. It is also possible that traveling to the future could disrupt the natural flow of time and have unpredictable effects on the universe.
