Professor Brian Cox Time Travel Possibility

Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine.

No idea what he's saying but I could listen to this man speak all day!

So on a smaller scale, just going at a speed of say 500mph on a plane, you travel forward in time by a fraction of a picosecond.

I'm not an expert but I've read it somewhere.

1. When traveling close to the speed of light, the time you experience will be much less than the time experienced by those on Earth. This effect doesn’t mean Earth physically experiences 5 million years in your 100 years of travel but rather that time dilation makes it seem as if you are aging much more slowly from the perspective of someone on Earth. The discrepancy in aging is a result of the relative nature of time as described by Einstein’s theory of relativity.

2. Time dilation effects describe how time is experienced differently for observers moving relative to each other. When traveling at speeds close to the speed of light, a traveler ages more slowly relative to those who remain stationary. This effect does not allow for traveling to the future in a literal sense; it only changes the rate at which time passes for different observers.

Pity, because the past is where the good stuff is. I'm dreading seeing what happens tomorrow, never mind a hundred years from now.

[Spidey-eqeh]

Good thing I'm working on a time machine that USES static black hole energy.

[delamar]

Oh no, there goes my Sports Almanac collection.... :D

I used to be against the belief od time travel into the past but there have been many stories of people who claimed to have time slipped, as well as to parallel universes. Its hard for me to say all of those are bogus and it only takes one being true for past time travel to be possible

However, by the time you have returned to earth, all people on earth will have died since the earth has now come dangerously close to the sun.

[jagathwal]

If Andromeda is 2.5 million light years away, then how will anyone travel there (& BACK!!!) in 100 years, by travelling slightly slower than the speed of light 🤔??

[RichardGilbey]

Electric flux is 5-1*10 because 5carbons to one atom
This allows the speed of light to be so fast and matter to be so stable
To time travel you would have to change the constant of electrical flux
Meaning
1 A vacuum would store light energy until it cooked you
2 travelling just one minute would take 500 years of a human life
3 planets would start to stretch down the galaxy like playdo
This is why electrical flux is linked to quantum design and is a constant.
Nothing stops you using this as a telescope of time to view the future ab=Q5

[stevejones]

Time is just a construct. Just because you may live on a planet that revolves much faster than earth causing you to live for a thousand years doesn't necessarily mean you live longer than a person on earth.

[Tenly]

I just want to go far enough into the future that the $2, 000 in my account will have time to grow into a billion.

[andrewfricker]

your atoms slow down (ageing)by going very fast....is what hes saying....

[stuartsinclair]

Ohh dear….. time travel has been invented back in 2011….
I’ve seen test reports, and I have a list of distances traveled only forward in time

[fumanpoo]

If it's 2.5 million light years away, at the speed of light, would it not be 5 million years round trip?

[markb]

The universe is expanding faster than the speed of light...Its annoying people like Professor Cox saying nothing travels faster than light...Also another fact is, ""nothing we know of"" like WE know everything, , thats laughable..

[skab]

Only the Real Time Travel exists:

I believe in the real time travel, not future time. The time travel into future is a wrong concept. It is always the real time. For instance, light itself travels from Andromeda to Earth in 2.5 years, but the time lapse in this travel has always been real time 2.5 years, not future time, as we can observe it in case of light itself.

[sardarnauman]

How do you calculate speed of light what are the units of they are the same its n9t possible please.

[alekseykravtsov]

This man has no idea what he’s saying, the world that are created. It’s too small for him.

[mickdonedee]

If 5 million Earth years have passed its position in the Milky Way will have changed significantly. How will that spacecraft find its way back to Earth?
