travel

I have been collecting a few resources to demonstrate to some folks that travelling to Fukushima in Japan is perfectly safe. Eating fish from there is probably also largely safe, apparently, though I am not much of a fish eater, anyway. I have official travel sites, of course. And I also found...

Dateline: USofA: As the Thanksgiving holiday officially gets underway the day before Turkeyday, airlines are reporting few if any glitches and TSA lines at the largest airports are reporting waits of fewer than 20 minutes. Meanwhile, those traveling over the river and through the woods via...

Hello everybody, Just a few questions that are on my mind. 1) If something is travelling faster than sound, is it correct to say that an observer towards whom the object is travelling will see it closing in in complete silence (barring any ambiant noise, of course)? If so, at which point...

Got this from expedia: Bolding mine. We're citizens, dammit. We can go where we want after entering the country. An iron curtain is decending across the US, and it upsets me greatly. Very glad to be living in Canada right now. What's going on in the US is abominable.

Recently i was told a time travel theory which seems somewhat plausible, yet i cant seem to apply it or explain it in such a way that can make it seem true to me.. The theory goes something like this.. Due to the fact that the Earth gets its light from stars, you can use the stars to see into...

Let's say someone were to claim that they were able to travel in time back to, say, the Paleozoic Era (between 250 and 500 million years ago), and return to the present. They claim that they would be able to observe but not interract with the environment, as that would impact the future and...

I tend to believe quite strongly that time travel will never be possible. The main reasoning I offer for this belief is as follows . . . A particular moment of time is described by the exact relative positioning of every single part of the universe as it exists at that particular moment of...

If it is impossible to travel faster then the speed of light, then it must also be impossible to travel faster than half the speed of light because of the following . . . If A travels away from “static” position B faster than half the speed of light, and C travels away from B faster than half...

Has anybody heard of this?: http://www.physorg.com/news10789.html Would be nifty if true. Any opinions on the subject?

I am fascinated with time travel and the effects of how it should work when practiced. My understanding is that gravity is caused by objects moving forward in time so I used simple deduction and figured that objects moving backwards in time create anti-gravity, this theory however seems to only...

The 'Stupid Teleportation topic' thread in the 'Religion and Philosophy' forum reminded me of a particular conundrum that we, as a highly technological society, face. In the not too distant past, I was very 'starry' eyed about the prospects of humanity venturing out into the universe (to...

From this article. I've always liked that teensy hope offered by TLOP. This kinda killed all my dreams of a second chance. I feel stuck and let down by science. Of course, I never wanted things to change for everybody - just me. Just me would be fine. I didn't think that would be too much to...

On the news this morning a political analyst was discussing Tom DeLay and his (alleged?) improprieties. I don't want to get into the DeLay specifics; I just wanted to mention how the following came up. The analyst was basically defending DeLay and said something to the effect (paraphrasing)...

Hello all..I've searched this using the search button and on google and have found nothing. My question is.How can radio/light/other waves travel in space while some waves such as sound can not? Does it have to do with the fact they are electromagnetic waves? Why don't they need a meduim? How...

I was thinking about this the other day, and I'm very curious if anyone else has thought of this before me. Okay, here goes... Say you have a person that uses a time machine to go back into time. What he does in the past is he kicks his father in the... family jewels, thus delaying him for a...

Sheesh! And people complain that their council tax is too high!! Heres a hint for my countrymen, if you want the government to wipe your arse and spoonfeed your babies, dont be suprised when you asked to pay for it! http://news.bbc.co.uk/1/hi/education/3537871.stm

This came up recently, I think on one of the Mars thread, when someone mentioned the tremendous amount of time it would take to get anywhere outside of the Solar System. Someone mentioned that with a propulsion system capable of constant 1g acceleration, you could cover tremendous distances in...

With 32 days to go before TAM II, I thought I'd start a thread for people to post their travel plans so we can meet at airports, get seats together on Southwest, get shuttle rides to/from the airport (http://www.randi.org/vbulletin/showthread.php?s=&threadid=28700), etc. In other words, we can...

Look at this guy's story. I put this here because it deals more with politics and current events than anything else. http://www.johntitor.com/ I more or less don't believe it, but there could be some sort of conflict like the one he outlined.

This is my first thread and my first post, so I figured I'd welcome myself to JREF with a question I've argued with one of my friends in particular about. I wouldn't be surprised if someone like him rose up to debate me again. As you can tell from the subject heading, I am talking about the...

I apologize if this has come up before. I had an insight once many years ago about time travel and forgot about it until it came up in conversation the other day. I submit my idea for review: The well-known time travel paradox works as follows: An engineer (let's face it, scientists never...

This is really a fluff topic. It arose from reading some short stories around the subjects of lightspeed travel and a couple books on the subject by physicists. Now, I'm an armchair physicist at best with merely an undergrad minor in the subject, so bare with me, and please correct me on...
