assuming light speed travel is possible...

how do you steer?

I’ve heard that subatomic particles do a ton of damage based on how fast they move.

so, what happens when your light speed ship collides with an asteroid? it’s much larger than a sub atomic particle and does way more damage than one. could you even see a meteor coming when you’re going that fast?

Could you even [b]see[/b] if your going that fast? The only reason your eyes work is because light shines on everything you’re able to see. if you’re traveling with light do you see nothing or everything?

Let’s say you have your ship’s shields equipped, that’s fine, but your bound to hit something big enough that’s gonna slow you down and I doubt they are gonna have airbags for that type of collision.

sad I’ll not be around to see that shit. We’re headed for another dark ages.

kinda off topic but still same genre, Einstein (I think it was) said that if you had a ship fast enough, a telescope powerful enough, and an unlimited amount of time, you could catch up to and pass all of the light that has escaped the earth, then turn the ship around, load up your telescope and view everything that has happened on the earth from the beginning first hand.

I would imagine that way off in the the future they will develop a way to capture and collect that type of light and they will be able to do away with courts because they will be able to go to the instant replay by going to those images held by the light.

At the speed of light, length goes to zero and time stops.

At 80% the speed of light, length shrinks by 40-something % and time slows.

Light speed is too slow.

ok I’m fascinated by this field but have very little knowledge of actual inner workings of it.

so don’t take this as me being a smart ass but from what you wrote up there … Why?

if length goes to zero how does it travel? and shouldn’t it not even exist if it can’t travel? and I still don’t understand how time “stops” if you’re moving at the speed of light? the earth is still rotating around the sun and that is how we tell time. so, so what if were going super fast. if we travel the earth 8 times in a second we are still a second older so it stands to reason if you are going at the speed of light for 6 mos you are going to be 6 mos older because you are still measuring time by earth standards. so when you get back to earth everyone will be only 6 mos older rather than 3000 years or whatever the number is.

Never mind the fact that any body travelling at the speed of light would need to consist of infinite mass… [cool]

Last time I drove at light speed my wiener disappeared. So I drove backwards slightly slower but only got 40% of it back.

Yeah, well, contract as it may, you would’ve lasted longer [laugh]

HAHAHAHA!!! Good point!

Read up on Einstein’s theory of relativity for the speed of light relativistic effects and particle physics for the subatomic particles of quarks, leptons, and their energies.

I barely understood what you just wrote so I doubt I’ll understand Einstein. maybe he’s got a “for dummies book?” math has never been my strong point.

Shit happens and it’s all relative to where yr standing. Now go back to sleep.

Seriously, a Brief History of Time is a really great place to start.

This happens all the time. It’s detachable.

grmpy check out this book:

http://www.amazon.com/Physics-Impossible-Scientific-Exploration-Teleportation/dp/0385520697

Michio Kaku is great at explaining really complex theoretical science and breaking it down to a level that is only one step over your head and not a hundred. In this book he looks at the science, lack of science, or pure theory behind faster-than-light travel, time travel, force fields, telepathy and alternated dimensions/realities, and gives a tentative time frame of when, if ever, humans may theoretically achieve these accomplishments.

He also discusses the Kardashev Scale http://en.wikipedia.org/wiki/Kardashev_scale, which I always thought was a cool concept. Mankind is currently rated about .72 out of 3- I hope I live to see us make it to a 1.

Thanks bob, I’ll give those a looksee.

Yeah, that’s a good point, but you should also avail yourself to the plethora of detailed analysis done by Dr. Frans Toglor on the systematic covalence of microdermal thermal transitions of molecular ineptitude. He proved that theoretical compensatory shifting of the triptids was actually more an influence on the plasmatic nuetrospecs than it ever was a catalyst for protophotonic dissipation.

Or you could just watch the “Time Travel” episode of Wonder Showzen with the audio commentary on- it’s Michio Kaku again and he breaks it down pretty well in half an hour. I always thought it was awesome that that insane crazy vulgar puppet show had DVD episode commentary from theoretical physicists and sociologists and historians and shit. It’s like a complete 180 from the actual episodes.

Wow, I have that show on DVD and I never noticed there were commentaries.

That sounds awesome.

Speaking of space travel etc…has anyone else here been following this??:

http://pluto.jhuapl.edu/

Being something of a deep space exploration nut, I’ve been following this probe’s progress for about the last 3 years. I have even made up excel sheets charting its progress.

Can’t wait til it beams back images of Pluto!

Anyone here know any good sites (with pictures not just text) that deal with future deep space exploration (not science fiction though)??
