re: Time travel

There's potential for some great sci-fi out of relatively recent advancements in quantum physics. It's truly amazing.

I mean, we're, like, always time traveling, when you think about it, man.

Already happened. But only once.

Me and my friends in high school used to get high and talk about time travel. We pretty much always concluded you can only travel backwards in time and never to the future. Unless you believe in Doc Browns paradox of alternate time settings.

YOUTUBE explaining the tenth dimension

Here's a brain melting link that attempts to explain ten dimensions

I almost committed suicide at 6

I believe we can speed up/slow down time...perhaps even halting it...but never go back or forward in time.

The whole alternate timeline just doesn't seem possible to me.

Although...I do believe that eventually we will be able to de-age our bodies...Not necessarily making us immortal (because we could still get shot)...but reversing the aging process.

It's a really interesting video but there's a lot of different articles out there explaining that it's inaccurate. The guy that came up with it isn't actually a scientist and apparently misapplied a lot of principles of quantum physics. I only know because this thread made me look that video back up when I first saw it and I was disappointed to find out about its inaccuracy

Regarding aging, telomeres are pretty interesting. Basically non-coding segments at the end of DNA strands. A little bit is lost with each replication and when enough is lost, lots of pathways are triggered for cell death, cell senescence, etc.

People have thought that extending them may prevent or delay aging at the cellular level but another concern is that they act as a "safety mechanism" since cells accumulate mutations as they duplicate and, by trying to limit the number of replications, maybe telomeres help with preventing cancer.

Pretty interesting stuff if you're into that kind of thing but there's not a clear consensus on it and it's not something I actively follow so I can't really tell you exactly what direction the research is taking currently.

ETA: New stuff from a Stanford lab. Pretty cool but probably a long long way from any kind of clinical application.

I think physicists have conducted some experiments relating to small particles appearing to travel in time.

As a result, some big guns in the field now answer this by saying it might be possible, but the popular understanding of the concept doesn't seem to be practical.
