Well, since this guy has a time machine, he could first go WAY back in time and grab a dinosaur. Something small like a Velociraptor.
He could then train the raptor so it’s ridable (using the 3102 edition of “How to train a dinosaur that you’ve brought back from the past using the ACME Time Travel Modulator”). THEN go to 1970 and ride into town in style.
That should do it.
Well, it worked for me anyway.
:dubious:
Assuming the effects of one’s existence don’t disrupt things too quickly, I think many people remember trends and products, and whether or not they are successful. Also whether or not songs are hits are not. For a while at least, one could at least impress their new friends, if not convince them.
On further reflection, these fashion-driven things probably would be the first things disrupted. Maybe big news events might stay in synch longer.
Wouldnt it be obvious?
Show them the time machine you came back with.
Barring that, a demonstration of time travel would be pretty good.
you could do the prophesy in an evelope trick. Write down whats going to happen and seal it in an envelope and have them open it after the event to minimize causality problems.
Bring back something that didnt exist in 1970 like a CD, fashion sense, a Star Trek DVD (bring the dang player too), viagra (that will be fun demonstrating), proof that the Mets won the world series.
That is by far the single best idea I’ve heard in a long time, you should be writing scienceifiction.
…and spelling for me too. :o
I don’t know if I could convince anyone, but I’m sure as hell buying stock in IBM and Microsoft.

Naaah. There are lots of psychics who do this all the time and reasonable people don’t believe they’re from the future, do they?
Or are they?

I would tell them that during the 1989 world series their is gonna be one helluva earthquake in San Francisco.
Oh yeah, and I would tell the army to go ahead and close their Kent State recruitment office.
Actually, they would. Both weather patterns and seismic activity would be disrupted by an actual change in history, although the seismic activity probably wouldn’t be detectably different for hundreds of years.
In any case, this is still assuming that it’s possible to change history.
Screw convinicing people. Just bring back some gold, convert it to current cash, and deposit the cash in an interest-bearing account(in an institution you know will still be around in your era) then hop back to your time and live like a king. 
Enjoy,

time travel suggest predestination - which suggest that we dont have free will - so whether you convince them or not is not up to you 
Or more precisely, it is up to you – but you can’t choose what you choose.
Simple. Just take along a nickel or a dime dated 2002. There’s no way it could be faked, because counterfeiting is illegal.
Ask yourself this; what would it take to convince YOU that someone was from the future? Kind of simplifies it, doesn’t it?
For my money, a perfect prediction of future events would do the trick. If someone said they were from the future and showed me a 2008 copy of the Sports Encyclopedia: Baseball, and lo and behold the 2003 season unfolded exactly as stated, down to the last stat, I’d be convinced.
—For my money, a perfect prediction of future events would do the trick.—
Why? An alternate hypothesis with the exact same effect, equally possible, is simply that they can see the future. How would you tell one from the other?
I would bring back as much information that i could about the year after i arrived (i arrive in 1970, i bring back info from 1971) im talking about random peoples birth records, newspapers, death records, press releases. ANYTHING i could.
as soon as i get there i take them to the government, explain my story and tell them to keep it 100% confidential.
They keep all my stuff for 12 months and i come back to their headquarters and they open up the safe and realise im the real deal.
I explain to them that i am not there in anyway to make money or take advantage of people, but to help the government.
Averting crisis’, saving lives, that sorta thing.
but no one will EVER know about me being there.
One way would be to submit to a medical scan if one has plastic tooth fillings that didn’t exist in 1970, ditto with hip implants or other medical artifacts.
Once could also bring along a cell phone or a laptop computer with DVD-ROM drive, which would be considered Buck Rogers sci-fi material in 1970.
Psychadelic coloured contact lenses. Only the hard ones were around in the 70s, AFAIK.
