Summarise the main points from the powerpoint slide in the space below

Aristarchus of Samos (an ancient Greek astronomer) is believed to be the first person to say out loud that Earth wasn’t the centre of everything and that it was actually the Sun.

This was way back in around 300 BC.
Even before this, philosophers Philolaus and then Hicetas had thought that Earth was moving around some kind of ‘central
fire’.

As far as anyone can tell, no one really took the idea much further at the time and the theory wasn’t developed until
many centuries later.

- Aristarchus of Samos is believed to be the first person to suggest that Earth is not the center of the universe, but rather the Sun.

- This occurred around 300 BC.
- Prior to Aristarchus, philosophers like Philolaus and Hicetas had also entertained the idea of Earth moving around a "central fire".
- However, the idea did not gain much traction or development at the time and was further developed many centuries later.

- Aristarchus of Samos was an ancient Greek astronomer who proposed that Earth was not the center of the universe.

- This idea was first suggested around 300 BC.
- Earlier philosophers like Philolaus and Hicetas had also proposed similar ideas, suggesting that Earth was moving around some kind of central fire.
- However, these ideas were not extensively developed or widely accepted at the time. The theory of Earth not being the center of the universe was further developed many centuries later.

The main points from the PowerPoint slide are as follows:

1. Aristarchus of Samos was an ancient Greek astronomer who proposed that Earth was not the center of the universe, but rather the Sun.
2. This idea was first spoken aloud around 300 BC.
3. Prior to Aristarchus, philosophers like Philolaus and Hicetas had already speculated that Earth revolved around some kind of central fire.
4. Despite these early ideas, the concept was not further developed until many centuries later.
