Free Willy

I thought I'd throw this out there, as the topic of my research paper, but also because I'm interested to know: Is there free will? I look at time as deterministic, but not without some degree of free will. We are all working towards some point that is predetermined, but how we get there is up to us. For example, if we wanted to go out to the mall to get a gift for someone, we could take the bus, a car, a taxi, walk, bike, or hoverboard there. But the end result is the same: we end up at the mall. However, whatever way we decide to get there comes with consequences. If we use a taxi,w e may want to spend less money. if we walk, it takes much longer and uses far greater energy. But that doesn't stop us from getting to the mall. In other words, we are determined to be somewhere at some point, but we take whichever means we wish to in order to get there.

THe stupid grandfather paradox

I was going to do my research paper on the argument that time travel was possible. However, there seems to be no way around the grandfather paradox except for picky grammatical and word usages. Does anybody have any ideas? I really want there to be the possibility of time travel. That's why i took this course, and the stupid grandfather paradox is ruining everything!

The beginning and end of time

If time had a beginning would it have to have an end, and if it has an end would it have to have a beginning?
It seems like if it has an end, it would have to have a beginning. It would be strange for time to just being going along and end all of a sudden. It does seem like it could possibly have a beginning with no end to me though. Does anyone else have any thoughts on this?

Time Travel and harry Potter

With the release of the fourth Harry Potter book on friday, HBO has beenplaying the third Harry Potter. For those of you who have seen it, it's theone where there Harry and Hermione time travel at the end. Watching this,it got me thinking about time travel in general and wondering if Harry Potterwas a consistent time travel story. The story itself seems to be a consistent time travel story but there's one part which confuses me. When Harry and Hermione finish their time travel story, and by this I mean they arrive back at the "present" time, they see themselves starting their time travel. Wouldn't it be the case that when the new Harry and Hermione arrive at the present time after their time travel journey, they would see another Harry and Hermione embarking on their journey. So, wouldn't there be an infinite amount of Harry and Hermione's and wouldn't there be parallel universes because when harry and Hermione finish their time travel, they go forward in the future, but the Harry and hermione who start their time travel go back in time. What do you think about this? Is time as Matt said, like an infinite amount of frames each one replaying so we are able to go back to it or is it something else?

How would we build a time machine

Nigel said...
This is a question. If time travel were possible, do scientists believe we could ever even approach having the technology capable of sending someone back in time? How would they go about building a "time machine"?

Grandfather Paradox

What I don't like about Lewis' paper is that he says that time travel can'toccur because you can't change the past. But why do you have to change thepast if you time travel? Isn't it feasible that someone just went to thepast, didn't do anything, didn't breathe, didn't move, but just observed.Then, he went back to the future. He time traveled and nothing changed. Whatdo you guys think?
