Historic evidence of universe’s Big Bang birth found

A team of researchers have found undeniable evidence for the explosion that gave birth to the whole universe, and scientists all over the planet are celebrating. There have been a string of theories leading up to this discovery, which makes it that much sweeter.

According to the Big Bang theory, all the matter in the entire universe was once compressed into a tiny dot so small, it would have been invisible to the naked eye. Then, some trigger went off 14 billion years ago which caused the dot to explode in a big bang! According to the cosmic inflation theory, the universe rapidly expanded after the explosion and became the vast starry blackness that we know today. While there has been a lot of strong evidence to support both theories in the past, never before has there been such rock solid proof until now.

For example, there seems to be heat left over from the Big Bang explosion, in the form of a glowing energy known as “cosmic radiation.” Also, the universe appears to be constantly expanding, even today, which supports the cosmic inflation theory. Now, if this inflation theory was true, physicist Albert Einstein predicted there would be evidence of “gravitational waves”, or basically ripples in space and time. However, there has never been a mega discovery to hit the bullseye and truly confirm the event… until now.

A team of researchers led by Harvard actually managed to discover these mysterious gravitational waves! Using a super sensitive telescope in the South Pole where the air is cool and stale, they found very faint gravitational waves. Like the researchers described in a press release, the gravitational waves squeeze space as they travel, leaving distinct patterns in detectable cosmic radiation. According to the scientists, these findings are “a signal from the very early universe, from the beginning of time.”
