This is the most beautiful sermon I have ever heard. I wish all people in this world could be comforted by what is true and not what they imagine to be true... "The universe and its scientific explanation fill me with awe at the wonderment of what is, and I am comforted at the thought of my tiny little place in the vibrations and energy that make up everything. We are the stars made conscious." Amen... (John Eef Ees facebook member)

You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed. You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid energies of the cosmos, you gave as good as you got.
And at one point you'd hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you. And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy will go on forever.
And the physicist will remind the congregation of how much of all our energy is given off as heat. There may be a few fanning themselves with their programs as he says it. And he will tell them that the warmth that flowed through you in life is still here, still part of all that we are, even as we who mourn continue the heat of our own lives.
And you'll want the physicist to explain to those who loved you that they need not have faith; indeed, they should not have faith. Let them know that they can measure, that scientists have measured precisely the conservation of energy and found it accurate, verifiable and consistent across space and time. You can hope your family will examine the evidence and satisfy themselves that the science is sound and that they'll be comforted to know your energy's still around. According to the law of the conservation of energy, not a bit of you is gone; you're just less orderly. Amen.

Extra dimensions are old news. The newest mind-bending descriptions of reality dreamed up by the world’s smartest physicists, and explained by superstar superstring theorist Brian Greene in his latest book The Hidden Reality, include untold numbers of extra universes. A million universes isn’t cool. You know what’s cool? Ten to the 500th power universes. Greene likes to drop you into the middle of the action first and then explain the backstory (and sometimes it does feel like a full-scale intellectual invasion is happening), but he has an elegant knack for anticipating questions and immediately dealing with any confusion or objections. http://www.makeahistory.com/index.php/your-details/32324-superstring-theorist-brian-greene-and-his-idea-of-an-infinite-number-of-universesExtra dimensions are old news.

Russian physicists seriously believe that the Large Hadron Collider can be used for time travel. However, it will only happen when it starts working at full capacity and stops breaking down.
If earlier time travel was considered science fiction, now it suddenly turned into the favorite pet project of theoretical physicists. Renowned physicist Kip Thorne of the California Institute of Technology once said in one of his lectures:
“Once upon a time, time travel was the exclusive prerogative of writers. Serious scientists were shunning it like the plague, even when they were writing novels under a pseudonym or were secretly reading them. The times have changed! Now in serious scientific journals you can find a scientific analysis of time travel, authored by outstanding theoretical physicists. Why this change? Physics simply understood that the nature of time is too important to give it to the mercy of writers.”
Today, there are many different schemes of devices designed for time travel. The main one is the Large Hadron Collider. It was launched in the fall of 2008. This is the most powerful particle accelerator in history located on the border of Switzerland and France. In its 27-kilometer ring scientists are trying to collide beams of protons accelerated to nearly light speed. As expected, this device will provide new information about particles and forces acting in space, as well as will reproduce conditions that existed immediately after the Big Bang gave birth to the universe.
Russia Today: LHC's little brother to beam near Moscow
After launching the collider, people were scared of the giant black hole capable of swallowing the Earth. Yet, scientists quickly calmed the population saying that in case of a collision of particles in the collider, the holes that may appear would be microscopic, or so large that they can be used as a handy tool for time travel.
This sensational proposal was made by two doctors of physical and mathematical sciences, Professors of Institute of Mathematics named after Steklov, Irina Arefyeva and Igor Volovich.
“Modern principles of theoretical mathematical physics allow the possibility of time travel,” explains Volovich, a member of RAS. “One of the admissible models of working time machine is the so-called wormhole, that is, a space-time tunnel leading to another time or space. And the probability of formation of a wormhole in the LHC is comparable to the probability of occurrence of the black hole itself, which can occur when particles collide with high energy.
As explained by the physics, wormhole is a tunnel connecting different parts of space and time. Entrance to the tunnel may be the size of a star, a planet, a house and even a speck of dust, depending on a purpose of the tunnel use. After all, there is a difference between sending a photon or a group of tourists. You can get to another galaxy, or another universe. And you can also get into in the past. In terms of the physical properties, the entrance to the wormhole is very similar to the entrance to the black hole. The difference is that you can come back.
Since the LHC is designed, figuratively speaking, to create a part of space on Earth, then it can be used to obtain dark energy. This is also an important detail of creating the miracle machine. Another necessary condition for making the machine work is to distort space and time so it closes up in a ring. And the LHC is quite capable of that.
“This phenomenon in physics is called “closed time-like curve,” explains Professor Arefyeva. “It allows, at least theoretically, returning to the past.”
“Is it possible to have a paradox described by Bradbury, when a traveler caught in the past accidentally steps on a butterfly, which results in coming to power of a different president in his time? “
“We expected such issues,” says professor Volovich. “We came to this conclusion: time travel may change the course of history, but not very significantly.”
To make time machine the reality, the scientists stress the need for the LHC to reach at least the design capacity (now it is working at half capacity) and stop breaking down.
“So far, our biggest home is that the LHC will demonstrate the existence of wormhole. If some of the collision energy in the collider disappears, this can be explained by the creation of particles that pierce time through wormholes.”
Research and Development Center of the European Council for Nuclear Research (CERN), promised that the LHC will start working as expected in September. Then it becomes clear whether Russian physicists were right in their solution of the most intriguing problem of mankind.

Antimatter galaxies and dark matter have long haunted physicists' theories, but no instrument in orbit has had the power to confirm or deny their existence. Now a $1.5 billion cosmic ray detector scheduled for launch in 2010 could usher in a new era for discovering all that's weird and wonderful about the universe.
Cosmic rays consist of high-energy particles that emerge from catastrophic events such as supernovas, and may also hold the clues to whether antimatter galaxies and dark matter truly exist. Detecting cosmic rays firsthand from the ground has proved difficult, because they collide with atoms in Earth's atmosphere and break up into a shower of secondary particles.
"Earth's atmosphere absorbs everything, so you cannot study primary cosmic rays until you go to space," said Samuel Ting, an MIT physicist who first proposed a large cosmic ray detector back in 1994.Antimatter galaxies and dark matter have long haunted physicists' theories, but... more
