The topic of science no.1

well they actually did a test with the sr71, and 2 precisely timed clocks. they had the sr71 fly round the world as fast as it could go.

when they brought it back the clock int the sr71 was slow but by sucha a minescuel amount...........

they also did it with the space shuttle. same thing. exept for a month. this time the difference was greater.


so, inother words, the people who live in the rocky mountains, age slower than we do, but its so miniscule its next to nothing.

Time travel is possible, at least travelling into the future.
If you\'re travelling on a space ship that\'s going really fast, and stay on that ship for let\'s say 10 years, time on earth will then have gone by much faster, maybe the time on earth has past like 15-20 years.

There are some pretty simple equations to calculate these kind of problems.

Maybe Bossieman can slap \'em up and give an example.
T1=T2/((1-(v/c)^2)^0.5)  <--- is that the correct one, don\'t remember.

T1=the time that has past on earth
T2=the amount of time that\'s gone by on the space ship
v=the velocity of the space ship
c=the lightspeed constant

Let me know Bossieman if this is correct coz I don\'t remember

I\'m curious as to the "why" it happens...

Does that mean that if you park a spaceship 200K miles over the earth, and accelerate to the speed of light in 2 seconds, what would you see in the back window of the spaceship? (lets pretend we actually had a back window facing the earth )

1) The earth would slowly disappear from view since we are traveling at the speed of light.

2) We would be frozen in place and therefore we would not notice anything.

3) If we were to look through the back window of the spaceship, the earth would remain as it was just before we hit the acceleration button.  

Wish i knew for sure.

ok if we accelerated to the speed of light, technically everythign would stop. but there is no possible way to get to the speed of light, if einstien is correct. so the fastest way to travel around would be to use the ripples in space-time to get arount the universe.

There was a show about this topic on PBS just the other day.  I watched 4 hours of Einstein\'s discoveries, space, and other stuff.  I never knew Einstein descovered so much.  If you have a chance to watch that show (and if they show it where you live), they have a computer generated movie showing the "space-bending gravity" theory.

So what exactly is a "white hole?"

Mucho interesting topic!

I hope "Vetenskapens Värld" (World of Science) show the program IronFist was talking about..

They show alot of interesting stuff.. This is the main man!

First, time dilation is not science-fiction, it is true and have been proven many times.
The formula that JP posted earlier is correct, it shows how time for observer 1 relates to time  for observer 2.
example:
We have the formula: T1=T2/((1-(v/c)^2)^0.5)

JP´s velocity is 255E6 m/s
c=300E6 m/s

Assume that JP´s  mesaure the time and stops the spaceship after exactly 30min (his clock)

This gives:

T1= 30/((1-(255E6/300E6)^2)^0.5)=56.9 min

What does this mean?!?
If the experiment started at 10 AM , Bossieman stands on the ground and makes sure that his clock and JPs clock shows the same time. When JP returns the 2 clocks wont show the same time any more.
My clock will show 10:59 and JPs will show 10:30.
This is not SF this is science.
This is the reason that shortlife particles can be detected here on earth. Take a particle that travels at the speed of 99.9999% of light. This particle only exists for 2E-12 s.
It looks like this particle can never reach earth from say Proxima Centaurie. Distance 4.2 lightyears. If the particle has the velocity of  99.99999 % it seems like it would take over 4 years for this particle to reach earth. And because of the fact that the particle only exists for 2E-12s it seems like it would be impossible for this particle to reach earth. But still we detect millions of those particles each day. How is it possible?
The answer is Timedilation. Because of the high velocity of the particle the time dilation becomes hugh.
2E-12 s for the particle can be 10 000 years in our time.

Interesting stuff Bossieman,
Does that related to the atoms of our bodies stopping when we go at close to the speed of light? Well since we are made up of atoms etc... and these particles spin around each other, maybe when we are moving extremely fast in space they can not age, or even move since it would require too much energy for them?  Just a thought, which was bugging me..

It depends on the referencesystem. From my wiew the atoms almost stops, every chemical reaction seems to go slower. If i look at a radioactive subject that has a half-life of 30 sec and the subject has a velocity of 99.9999% of light I would measure the half-life to 50000 years. The time actually slows down!!
This is why we have all this particleaccelerators all over the world CERN is one of the biggest in the world. They accelerate particles to 99.99999% of the lightspeed and the looks what happens when the subject collides with another subject.

This is what could happen, notice this is not science-fiction this is true.

Assume that my grandmother has cancer. I have very much money. Can I save her?
If I build a spaceship that can go very close to lightspeed i could save her.
I build the ship, put my grandma in the ship and program it to accelerate to 99.99% of lightspeed. When it has reached that speed I say to the ship that it will go with that speed for 2 hours then stop the ship and return to earth. When the ship arrives at earth my grandma would have aged 2 hours(wrong but I assume that acc. 0-light speed is imidiately) and I would be dead and the year would be like 2435 here on earth

Take  a couple of twins. No 1 takes a ride in a spaceship att a very high velocity (close to speedlight). No 2 stays on earth. When no 1 returns to earth he could be like 25 years old but his twinbrother no 2 would be like 75 years old. This is not a joke it could happen

I heard some people say that if we had mounted a camera inside of this superfast spaceship, then we would see the people inside move very very slowly, that is so cool
So in a way we have a way of moving up in time, i wonder
if it will ever be possible to reverse that, and go backwards in time, to the time of dinosaurs etc...

travel back in time is something that aint going to happen.
Let me explain why.
Assume that I could go back in time.
I travel back to may 7 1975 and prevent my parents from having sex. I am born may 7 1975. If I prevent them from having sex then I would never exist.

Or this one. I take the PS3 chip in the year 2005 and go back to the year 2001 and give Sony the chip. They would go happy and pay me much. they save the chip and release it in the PS3 in the year 2005.

the question now is : From where came the knowledge behind the chip????

Or I go back in time and kill Hitler, then I would not exist either.

Heres a question.......is the burmuda triangle real???????

bossie,
do you believe in a multiplicity of History? Let me explain,
some say that
it would be possible to go back in time because even if you went back in time, and prevent your parents from ever having you in the first place... history would just diverge and spawn a new history without you, and this would prevent any paradox or destruction of you from the future.

In other words, when i take a pen in my hand, there was an alternative history-event that occurred at the same time i lifted the pen, but in that history-event i did not lift the pen... damn this will get confusing soon.

I think the Bermuda thingy is just gas that escapes in huge spurts and sinks ships/airplanes.  IMO. Maybe something else. What i don\'t believe in are:

1) Atlantis people abduct you
2) Little green men abducting you


These 2 explanations for the phenomena are off-the-wall.
