Will get their first 2 months completely for free

Near the Univeristy of Cambridge in the UK.

But the catch was that Hawking only sent out invitations

To the party AFTER the party had already taken place

派對已經舉行之後再向派對提出申請

You see, this was a party for time travellers

你看，這是一個時間旅行者的聚會。

And by only sending out invitations after the party had already taken place,

而且是在聚會已經舉行之後才發出邀請。

The theory was that only people capable of time travel would know about it and show up.

理論上，只有能夠進行時間旅行的人才會知道並出現。

Unfortunately for Hawking, nobody ended up showing up to the party.

不幸的是，霍金最終沒有人出現在聚會上。

He partied alone that day, but to any potential time travelers that are watching this video,

那天他獨自一人狂歡，但對於任何潛在的時間旅行者來說，正在觀看這段視頻。

You can change that by going to these coordinates on June 28th, 2009 and pay him a visit.

你可以在2009年6月28日到這些座標去改變這種狀況，去拜訪他。

Hawking believed that his invitations to this party would last for thousands of years.

霍金相信，他的這個聚會的邀請函會持續數千年。

And hopefully encourage somebody in the far future to come back and visit

並希望鼓勵某人在遙遠的將來再來訪問。

但是，這就自動提出了一個問題

Is traveling to the past even possible in the first place
