Will anyone from the future attend ? Image Credit: CC BY-SA 3.0 Ed g2s
Organizers of Stephen Hawking's memorial service have seemingly left the door open to visitors from the future.
Those wishing to attend the service, which will take place on June 15th at Westminster Abbey, have the opportunity to apply for one of 1,000 tickets that will be given out by means of a public ballot.
Intriguingly however, applications are open to anyone born before or up to the year 2038.
The peculiar choice of dates may be a nod to an experiment that Hawking conducted back in 2009 in which he announced that he was hosting a party and that time travelers were welcome to attend.
To further cement this idea, he didn't send out the invitations until after the party had taken place.
"I have experimental evidence that time travel is not possible," he said at the time.
"I gave a party for time travelers. I sat there a long time, but no one came."
Whether anyone from the future will turn up at his memorial service however remains to be seen.
"We cannot exclude the possibility of time travel as it has not been disproven to our satisfaction," said a spokesman for the Stephen Hawking Foundation. "All things are possible until proven otherwise."
I don't for sure, but I'm pretty certain. I think there is room for it in Relativity theory, but it involves traveling faster than light which is impossible. Here's an interesting piece, mentions wormholes...http://timetravelphilosophy.net/topics/relativity/
Well, what happens if there is no immutable "forward arrow-in-time"? After all, we exist, not in the past or future, but the concrete NOW. Perhaps the past, present and future is rolled into one grand mystery.
It's been mathematically proven that you can in fact travel forward in time. It's actually pretty much accepted that it possible now. Backwards is another question entirely though.
Time dilation is not time travel. It is merely a differential in how time is recorded based on a relative difference in velocity between two observers. The fastest any human has ever traveled - some of the Apollo mission astronauts - has been about 11 kilometres (7 miles) a second. The speed of light is 300,000 km/sec (186,000 miles/sec). We haven't even attained one ten thousandth of one percent of the speed of light. the formula for time dilation is; t' = t/[sq.rt.(1- v2/c2)] We have a long way to go before time dilation effects will ever effect us physically, and even then it will never ...

Actually Frank Tiplers calculations does show time travel is possible theoretically. Spacetine can be distorted by strong gravitational fields, and Tipler’s imaginary time machine is a very massive cylinder, containing as much matter as our sun packed into a volume 100km long and 10km in radius, as dense as the nucleus of an atom, rotating twice every millisecond and dragging the fabric of space-time around with it. The surface of the cylinder would be moving at half the speed of light. Basically you would need to use multisecond pulsar, we don't have then lying around in our back garden. So... [More]
