Will Humans Ever Achieve Time Travel?

But, again, zer0, this scientifically accepted "solution" bases it premise on another human assumption - that every other civilisation would behave as abysmally as humans do. There is no factual evidence for this theory given how little knowledge we have even of our own solar system let alone the wider universe.

 

True, the accepted "solution" is pure opinion based the observations of ourselves. But then what other explanation can you offer? Remember, we're talking about eternity. In scientific terms that means every possibility has happened; life has been given every opportunity to reach its greatest potential. Why don't we see a universe filled with life, as fertile as the Amazon jungle?

 

The answer to that is simple. We don't see a life-filled Universe because we are still struggling to see what is in our own back yard. We have only just started being able to detect planets around other stars in our galactic neighbourhood. It's going to be a long time before we can tell whether those planets support life of any description, whether primitive or advanced....and there are simply far too many galaxies, stars and planets to believe anything other than the probability of both being out there somewhere

 

We've derailed this thread enough so I'll just say this and leave it. In science, a theory is proposed and if it's logically sound and accepted, then it generally sits until someone can find a flaw or specifically prove it wrong. Example: Einstein's theory of relativity. It remains to be proven in practical (impossible) terms, but it's logically sound so it's accepted, taught, and used as a basis to develop other theories.

Fermi says given the infinity of time, and the nature of all life to grow and expand, then every corner of the universe should have life or clear evidence of life by now. But it's the opposite. Ergo, life is either transitory, or it can never achieve interstellar travel.

I'm not arguing with you but merely presenting the accepted theory that would explain the Fermi Paradox. You haven't proposed anything that logically refutes it. What you're saying is basically "we don't know enough yet". Fine, that's what ends most discussions on God (rightly so). But in the case of Fermi, it stands until someone can propose a credible alternative.

Trust me, it's a horribly depressing prospect to swallow that empirically we are alone (or rather, doomed before we can reach other worlds) even though we crave contact from the day we first see the stars. The instinct is to deny such a crushing thought which is probably why you're not entertaining the possibility. But if you can come up with a better alternative that gives us hope (not just "we don't know yet"), you'll be world famous. Greater minds have failed. This really does amount to a sort of God debate, and as it stands there is no scientific data for the existence of Gods, only faith. Whoever can scientifically prove God would be world famous. But again, greater minds have failed.

 

Yes...

 

Well Ty--I guess that settles it.

 

We have some extremely smart people driving technology right now, I think it’s possible, time will tell… I’d definitely go back in time to visit old family members

 

Maybe go back and see what Neanderthals where really like, I saw a documentary about them, people thought they were like apes but they made tools and art and jewellery, I would like to hear how they spoke to each other.

 

Very Interesting, I’m down to go back with you.

 

This is a flawed hypothesis, based on how long light takes to reach us.

As an easy to understand explanation.
A person leaves home and travels to meet you 25 miles away at 50mph. This takes 30 minutes.
If you left home to visit him and travelled at 100mph, you could meet within 15 minutes.

If you travelled at the speed of light, most people would assume that you would meet immediately.
This is wrong, since although the time laps would be immeasurable. it still exists as a + figure.
Only if you travelled an infinite speed, would you meet at the moment that you left.

To time travel, you would need to travel faster than infinite, NOT faster than light.

Time travel theories, always ignore that the speed of light is a plus figure.

 

Simply.............the faster you travel.............the sooner you get there?

You basicly go faster(forward) in "time"?

Mzzls

 

Exactly, time is a fixed point.
If I travel to a star where the light has taken 10 days to reach me, it will take me ANOTHER 10 days to get there at the speed of light.
If I manage to go a bit faster, I may get there in 9 days, 23 hours 59 minutes and 59 seconds, leaving me 1 second for a cup of tea before they zap me.
If I travel at an infinite speed, I would arrive immediately and surprise them, hopefully before they got their zapper out.
Any suggestion of arriving earlier, would involve travelling faster than infinity, NOT faster than light.

When we boil a kettle, most people see 0 degrees as the bottom temperature and 100 degrees as the top.
In reality water freezes at 273 degrees and boils at 373 on the absolute scale. Therefore their is no minus on the Kelvin scale, since their is no heat.
No one has ever managed to get below 0 Kelvin and even if they did, it would only show that the scale was inaccurate.
These are probably the same idiots who cannot accept why the cashpoint won't give them any money when their account balance is zero..

Look at it this way, in REAL life and applied engineering,...0 - 2 = 0........0 - 3 = 0....... but 2 does not equal 3.
In complex calculations, people have been known to make this mistake,

In REAL life, having less than nothing is a metaphor.

 

I hope so!! I’d love to go back to Ancient times. Times set in antiquity? Like maybe visit the Roman Empire, or Ancient Egypt or Metropolis? That would be awesome!!

 

I would love to go back in time and meet Jesus in His earthly carnation. Ever read The Time Travellers Wife? An interesting read.

 

I just read this thread in its entirety. After I stopped snorting and laughing, a question occurred to me.

Show of hands; how many of you are formally trained physicists?

Take your time. No rush, I'll wait.

 

Not me for damn sure. This is science fiction. If a "formally trained physicist" can show me that time travel is possible then I might change my mind.

 

It's probably best that we don't

 

The only thing we can be sure of is the Eternal Now. The rest is an illusion, Maya.

I don't believe we perceive the true reality due to our limited senses. We use tools to measure reality, but as we observe, we alter reality thru our observations. That's cause it's all connected in ways we still don't understand.

Scientists plug gaps in formulae with unknown variables to make it conform and measure, but we are still so far from understanding the big picture and probably never will.
