Time travel is not possible right?
After all time only has one dimension and this causes problems for any kind of data transfer to either past or future.
Time can flow either forward or backward but if that's the case you can never disconnect yourself from it. It will be everywhere you go. There's no a y(t) axis to help you freely move around in time.

but if string theory is correct and there are really 10 dimesions, wouldn't we be seeing a lot more constantly changing cross-sections from higher dimensions?

/sci/, I am not an educated man. I tried to understand Physics at school but it was completely beyond my understanding. You have to help me here

Please tell me Time Travel will one day be possible. And I mean the Hollywood, Back To The Future type where you can pick any point in the past and go back and visit it with ease.

Even if it an almost infinitely remote chance, please tell me it is possible. In theory. Maybe.

Maybe there will be a scientific renaissance during our lifetime. Maybe aliens will descend and teach us new things. Its not impossible. Maybe medical science will allow us to live for hundreds of years, long enough to see time travel become a reality

It is my wildest fantasy. I have obsessed over it since I was a child. Please tell me it could happen

Please

See where it loops around and comes down the wormhole? That wormhole is out there somewhere, next to Deep Space Nine.

So yesterday someone on /b/ talked about a book "Physics of the Impossible" so as I wandered through a bookstore today I accidentally found it, picked it up, and read it a bit.

I don't remember it thoroughly but he said something like; every singularity is a potential einstein-rosen-bridge. is this true or did I just misread it?

Ask me any/all of your space/physics/astrophysics related questions, I'll do my best to answer.

Circle.

So, I open up face book and see this.

>Ok. Ur right. The scientific method has problems with untestable things. But spiritual/religious claims aren't the only "untestable" things.

>You also can't test things like love or hate, but most accept them as actual, credible things. You can't test or use the scientific method to predict how much a stock will be worth on a particular day at a ... See More particular time and be right 100 percent of the time.

>Science also can't tell me how cold something is. Sure it'll say something is 32 degrees Fahrenheit, and I know that that is freezing for water, but I still don't know the quantity of coldness...

>You said we know that we are on a planet in space? How do we know that? Idk about you but I personally never used the scientific method to come to that conclusion. I heard my teachers say it and believed in their word.

>Evolution has yet to be proven. Yes science shows some findings but there are gaps in the claim. You gotta have a certain degree of faith in science to believe in evolution, I personally have never seen a monkey turn into a human.

>And not everyone attemps to satisfy physical needs. What about people that go on hunger strikes? Or choose to stay up all night to study? Or abstain from sex until marraige or longer?

>U said the scientific method is reliable to our understanding of the universe... but our understanding is minimal. Scientist don't know more than they know. So really, the scientific method is reliable to minimal.
