Can We Travel Faster Than LIGHT

CAN WE TRAVEL FASTER THAN LIGHT

Excerpts:

CAN WE TRAVEL FASTER THAN LIGHT


"The closest star is about 25 trillion miles away.
The fastest spacecraft we have today
would take more than 10,000 years to get there.


The speed of light is 186,000 miles per second,
or 670 million miles per hour.
Nothing goes faster than the speed of light.
It really is the maximum speed limit
for everything in the Universe.

Light travels a million times faster than sound.
It's fast enough to circle the Earth seven times
in just one second.


The way it moves is different
from everything else in the Universe.

Light would be seen to be moving at the same speed
no matter what my car was doing.
You don't add the speed of light to the speed of the car.
The speed of light is always the speed of light.



MORE SPEED -> MORE ENERGY
MORE ENERGY -> MORE MASS
MORE MASS -> LESS SPEED


The energy it takes to accelerate
increases and increases
as you come closer to the speed of light.
If, in principle, you wanted to go the speed of light,
you need and infinite amount of energy
to accelerate you that fast.
Or you're gonna get more and more energy,
but you're not going to get that much more speed.


WARP DRIVE

Miguel's idea stems from another aspect
of Einstein's theory of relativity --
that the shape of space can be distorted by mass or energy.

A warp drive can only function
with a mysterious power source --
negative energy.
... (today) negative energy is just unproven theoretical concept.


WORMHOLE


In this two-dimensional analogy,
the opening of the straw is just a circle.
But, because we live in three dimensions,
the opening of the wormhole would actually be
like the interior of a bubble.


... And we've proven mathematically they're unstable.

The negative energy needed to keep a wormhole open
in inherently too unstable.
A man-made wormhole would collapse the instant
someone tries to step inside.


TELEPORTATION


We could turn our bodies into information
and send that information from place to place
at the speed of light.

Chris Monroe and Steve Olmshenk
are quantum physicists at the University of Maryland.
THEY ARE PIONEERS OF TELEPORTATOIN.

Entanglement.


Steve and Chris have successfully transferred
the information from one atom to the other.
In other words, they teleported the atom.

... but the real question
is whether we will ever by able to teleport teh state
of all the 7000 trillion trillon atoms in an entire person
from one place to another.


In Physics,
every force has a particle that carries it.
Electromagnetic force is carried by light, or photons.

The electromagnetic force keeps atoms glued together
with a constant exchange of photons
that bounce from the nucleus to its orbiting electrons.


When you look in one dircetion on the sky,
the strength of the electromagnetic force
appears to decrease with increasing distance from us,
and when you look in exactly the opposite direction on the sky,
the converse is true.
The strenght of electromagnetism
seems to increase as you move to greater distance.

Electromagnetism is the force that is transmitted by light.
So if the strength of electromagnetism
is not constant,
it means that the PROPERTIES OF LIGHT ITSELF ARE CHANGING.

Once the laws of physics are allowed to vary in those equations,
THINGS HAVE TO BE REWRITTEN.
So its' back to the drawing board
for certain fundamental principles in physics.


HOMOGENEITY PROBLEM



FREEMAN: We are still a long way from becoming citizens of the cosmos.
The stars remain almost unimaginably far away.
... And, one day, we will reach it,
because what man can imagine, man can do.

The Universe: Time Travel

The Universe : TIME TRAVEL
History Channel
Season. 5 Episode. 4




http://www.history.com/shows/the-universe

http://en.wikipedia.org/wiki/The_Universe_%28TV_series%29


EXCERPTS:
TIME TRAVEL

"Time always go one way Forward.
Physicists call this Arrow of Time.

Cream mixes in the coffee,
it doesn't un-mix,
that's the arrow of time"


"All things in universe move
from ORDERLY STATES to
DISORDERLY STATS."


SPACETIME
"This means that whenever space warped,
so is time."


GRAND FATHER PARADOX.

"Physicists have come up with
at least 3 ways that nature might act
to prevent time travel paradoxes.
The first is simple: Nature prevents paradoxes
by making time travel into the past impossible.
In other words, it can't be done.


MULTIPLE UNIVERSES



You cannot change the past.

"We think that nature always somehow manages
to choose the solution that provides
self-consistency.
In other words,
You always get a solution
That does not produce a paradox."


"But we don't have to worry about about paradoxes
when we travel forward.
Taking the arrow of time into the future.


"The faster you move in space
time for you slows down
as compared to people standing still." -Einstein

Its proven by experiments.
The effect is called Time Dilation.


Russian cosmonaut,
Sergei Krikalev has logged
more than 803 days in orbit,
traveling 17,000 miles an hour,
making him the world's record holder
in time travel.

He is a 50th of a second slower
in the amount of time that has passed for him
compared to everyone else who's stayed on Earth.


To move 500 years into the future [Earth Time = 500 years]
You'd have to move at 99.99% of the speed of light for 7 years. [Space time = 7 years]

There no law of physics that says you can't go close
to the speed of light,
but your rocketship becomes hevier and heavier
as you go closer and closer to light speed.
So you require more and more fuel
to accelerate you smaller and smaller amounts,
and you need MORE THAN INFINITE AMOUNT OF ENERGY
TO ACTUALLY BREAK THE BARRIER OF LIGHT-SPEED.


Einstein's theory of relativity
says high gravity
also slows down your clock.


The Large Hadron Collider

is the largest, most complicated machine
ever created by humankind.

The Collider went operational
in Nov 2009,
And as scientists ramped up the power
the energy in its collisions
was increased almost tenfold
by March 2010,
And it will double that sometimes after
2013.


Today's theories of Space, Time, Gravity and Quantum Physics
are still incomplete.

And tools like LHC will help fill in the ever puzzling blanks.


WARP DRIVE
If we can expand at will,
we may be able to propel
a warp ship.
We make space Expand behind the ship
and make it Contract in front.
The wave of warped space
moves through the universe
FASTER THAN LIGHT,
while inside the so called warp bubble,
the ship is a passenger,
never violating Einsteins rule
against exceeding the speed of ligth.
