The Tampa Bay Rays are an American professional baseball team based in St. Petersburg, Florida. The Rays compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. Since its inception, the team's home venue has been Tropicana Field.
Following nearly three decades of unsuccessfully trying to gain an expansion franchise or enticing existing teams to relocate to the Tampa Bay Area, an ownership group led by Vince Naimoli was approved on March 9, 1995. The Tampa Bay Devil Rays began play in the 1998 Major League Baseball season.
Their first decade of play, however, was marked by futility; they finished in last place in the AL East in all but the 2004 season, when they finished second to last. Following the 2007 season, Stuart Sternberg, who had purchased controlling interest in the team from Vince Naimoli two years earlier, changed the team's name from "Devil Rays" to "Rays", now meant to primarily refer to a burst of sunshine rather than a manta ray, though a manta ray logo remains on the uniform sleeves. The 2008 season saw the Tampa Bay Rays post their first winning season, their first AL East championship, and their first American League Pennant (defeating the rival Boston Red Sox in the ALCS), though they lost to the Philadelphia Phillies in that year's World Series. Since then, the Rays have played in the postseason five more times, winning the American League pennant again in 2020 and losing to the Los Angeles Dodgers in that year's World Series.
The Tampa Bay Rays' chief rivals are the Boston Red Sox and the New York Yankees. Regarding the former, there have been several notable on-field incidents. The Rays also have an intrastate interleague rivalry with the National League (NL)'s Miami Marlins (originally the Florida Marlins), whom they play in the Citrus Series.
Through 2020, the Rays' all-time record is 1,726-1,896 (.477).
Hey all,
I wake up with morning to find an email from spaceweather which says:

1. Is there any clue as to how close two adjacent photons, coming from a distant star, in neighbouring paths, can be to each other?

It is often said that the paths of light bend, close to a neutron star? What happens if the ray of light is vertical to the surface . If we take into account the spacetime of that inertial body, the constancy of velocity of light holds, (or does it?). But shall we (as outside observers) ever...

Hi everybody,
We know that light is an electromagnetic wave.gamma rays are e.m.waves. Both of them have the same speed 3*10^8 m/s. Gamma ray have the property to penetrate in materials like wood,cement wall etc. But,light is not penetrating even in a single wood. What is the reason behind...

90% of the cosmic rays that fall on Earth are protons. So the outside of the Earth is hit by a net positive charge but does not seem to be, in particular, positively charged. How do you explain this?

So apparently vacuum energy is created and destroyed within Planck time by matter, antimatter annihilation. If someone could theoretically stop or slow down time, would it be possible to tap into vacuum energy? Since annihilation creates gamma rays, I suppose vacuum energy would face the same...

hi All,
why is this? some matter has a refractive index of slightly less than one for light in the x ray region. This implies a phase velocity faster than c, right? could someone explain what is actually happening here?

Hello,
