Science Brian Cox on Cern's baffling light-speed find

[DaGaffer]

Been trying to catchup with this thread, and physics is not my strong suit, but surely, if you're travelling at light speed, and things seem to slow down, that must be due to your sensory organs not being able to perceive at such high speeds? Visual awareness is not entirely needed, but surely that must play in to what we perceive during those speeds?

Your perception of time in the local environment doesn't slow down. For you, and the ship you're in, everything looks normal; but look outside and the outside universe will look like its slowed down (it will actually look blue in front of you and red behind, but that's not because of time dilation exactly, its another relativistic effect called the doppler effect that effects the light wavelength you're observing); and when you arrive at your destination, the clock on your ship will "behind" the time on the clocks at your point of origin; by how much depends on the percentage of the speed of light you were travelling at, and for how long.

I heard that if you go at the speed of light, you get babes.

Your right that if you looked outside the spaceship and could somehow see earth it would look like motion there was slowed but simultaneously you would experience less time even though you wouldnt perceive it.

You would literally enjoy less 24 hour periods (according to your on board clock) than people on earth and thus age less.

Couldn't you lot just say "time slower in spaceship" and spend the rest of the time watching porn?

 

[Job]

noo

 

[old.Tohtori]

Yeap, looks a lot like my crew alright :worthy:

Not for very long.

Thanks for the explanation! Kind of, just a little bit, makes it easier to understand. But what I mean is that, since noone has actually traveled at the speed of light, we don't actually know how sensory organs will behave. We do know that speed can mess up perception of things well below speed of light, and that our perception is quite scarily easy to fool.

 

[Tom]

Your organs would do exactly what they've always done. Only acceleration would affect them.

 

[old.user4556]

Unless you're there with your wife, then your organ wouldn't work.

 

[Job]

I remember this film/tv show from the 70's that had a family travelling across the galaxy in some ship and it was all done very realistically, they fired air into their faces to give the impression of the acceleration.
Anyone know what it was?

 

[TdC]

was it Space:1999?

 

[DaGaffer]

Shit show, but best spaceship evah! Used to have one of those when I was a nipper.

 

[Raven]

It's a pile of wank, but doesn't look all that out of time.

 

[TdC]

Shit show, but best spaceship evah! Used to have one of those when I was a nipper.

Yeah dude, I was forever building them in lego

Curses! Beaten to it!

 

[Tuthmes]

It's odd though as approaching the lightspeed does seem to change your perspective (well duh). Not sure what this means information wise or what it does to the lightspeed or going directly away from (or towards) you. As light always should travel at the same velocity (~300.000km/s) for you.

The doppler effect seems to indicate that you brake the light up. Perhaps someone can explain.

 

[Chilly]

Get a physics degree.

 

[Tuthmes]

Get a physics degree.

I'm thinking about it.

 

[old.Tohtori]

Ignore everything (theoretical)scientists do because they just make sh*t up when it's convinient?

wasn't there a guy in it with wierd eyebrows?

A loose connection between a timer and a computer led some of the world’s smartest particle physicists to conclude that certain tiny particles called neutrinos moved faster than the speed of light -- a declaration that shocked the science world and would have called into questions Einstein’s theories.
Citing sources familiar with the experiment, Science magazine’s website reported Wednesday that the 60-nanoseconds discrepancy that led to the startling speed conclusion came from a bad connection in a fiber optic cable connecting a GPS receiver (used to correct the timing of the neutrinos' flight) and a computer.
After tightening the connection and then remeasuring the time it takes data to travel the length of the cable, researchers found that the data arrive 60 nanoseconds earlier than assumed, the website said. (More data will be needed to confirm this hypothesis, the site cautioned.)

[Tom]

Just another theory as to the cause, nothing has yet been decided.

 

[Scouse]

Announcement tomorrow, scheduled retests not until May though, so no proper confirmation until then I guess...

 

[Punishment]

The earth is flat ! I will accept no arguements !

 

[Wij]

Tits have souls !

 

[Wazzerphuk]

Unless they're ginger!

 

[Zarjazz]

Ginger tits? Sounds like a fake tan gone badly wrong.
