Hong Kong scientists ‘show time travel is impossible’

HONG KONG — Hong Kong physicists say they have proved that a single photon obeys Einstein's theory that nothing can travel faster than the speed of light -- demonstrating that outside science fiction, time travel is impossible.

The Hong Kong University of Science and Technology research team led by Du Shengwang said they had proved that a single photon, or unit of light, "obeys the traffic law of the universe".

"Einstein claimed that the speed of light was the traffic law of the universe or in simple language, nothing can travel faster than light," the university said on its website.

"Professor Du's study demonstrates that a single photon, the fundamental quanta of light, also obeys the traffic law of the universe just like classical EM (electromagnetic) waves."

1. Once again scientists disappoint me

Just because we do not have the technology does not mean it something can't be done. Our views of science are still extremely small compared to the entire universe.

2. Nuh-huh!!

That's all I got.

3. Just Wait...

I've almost completed the flux capacitor.

4. At one point in time scientists "knew" the Earth was flat.

They also "knew" that the Sun orbited the Earth.

Declaring time travel 'impossible' seems awfully arrogant to me.

8. The flat earth thing is a myth.

After 400BC pretty much all educated people believed that the earth was round.

5. It is impossible...but not because of photon speeds....

but because there is no time.

6. Time flies like an arrow...

Fruit flies like a banana..

7. Isn't that a little bit backwards? If it obeys the rule, then time travel isn't possible

Only if a particle with mass could exceed the speed of light would time travel be possible - I think.

9. I refer you to Clarke's law:

"When a distinguished scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."

--Arthur C. Clarke
