For centuries now humanity has been curious about how the universe began, and the study of astronomy continues to intrigue, puzzle and excite modern society. For the most part, astronomers are still mystified about how the universe came to be and are always seeking answers to these questions.

A new study conducted in the expert community suggests time is running out and that, while technology will continue to progress and aid experts in seeking the answers they desire about the Big Bang, past evidence of the universe's early beginnings will dissipate at some point.

On the plus side, despite the fact time may run out, astronomers are predicted to have a little time to figure it all out. It is projected scientists have about 1 trillion years left to solve all of the great mysteries of the universe.

In a press release published by the Harvard-Smithsonian Center for Astrophysics on April 13, 2011, the researchers stated in a trillion years, the universe would be 100 times older than now and future "alien" astronomers would have a very different view than scientists currently have as the universe continues to expand and evolve.

The statement said "The Milky Way will have merged with the Andromeda galaxy to form the Milkomeda galaxy. Many of its stars, including our Sun, will have burned out. The universe's ever-accelerating expansion will send all other galaxies rushing beyond our "cosmic horizon," sending them forever out of view."

The Astrophysics Center says as this occurs and cosmic microwave backgrounds continue to fade and "stretch wavelengths of CMB photons" become longer, future scientists will have an inability to see the universe's early history that scientists can  see in the window of opportunity that currently exists.

Harvard theorist Avi Loeb who directs the Institute for Theory and Computation at Harvard-Smithsonian Center, provides some hope for future researchers.

Loeb says "We used to think that observational cosmology wouldn't be feasible a trillion years from now. Now we know this won't be the case. Hypervelocity stars will allow Milkomeda residents to learn about the cosmic expansion and reconstruct the past."  In the future, astronomers would not have to take Big Bang theories in faith, but instead have more conclusive evidence through careful measurements and clever analysis, says Loeb.

Essentially futuristic curious minds could use these "back up clues" according to Space.com (courtesy of MSNBC). Clara Moskowitz reports "Combined with information about the age of the Milkomeda galaxy derived from the stars inside it, our descendants could calculate the age of the universe and other important parameters."

What the future holds is unknown, but in the meantime researchers are bound to keep looking. The distant holes, nooks and crannies of the universe hold the keys to some deep spaces that scientists, and society as a whole, would love to unlock.
