Do you think that time travelling is possible??

By DeN inc. ·
It just struck my mind. What if we're able to travel to the future rather than the past? I think I would then go 1000 years ahead and start selling the currencies we have today. Haha.. I'll be rich

God I love that mindset of positivity

by TomSal In reply to Yes, it is possible

However I disagree.

It's great to say "nothing is impossible"...but yeah somethings really are impossible.

For instance -- it's IMPOSSIBLE for me to naturally have the powers to fly unassisted by any man-made vehicle, technology or contraption.

Also note-- if you say sky dive, that's not true flying -- its falling fast and you are still relying on man-made inventions (the plane to get you there, the parachute to keep you alive).

Also, not to discredit Michael Crichton, but I'm still more swayed by the credentials of Stephen Hawkins, the work of Albert Einstein and the like over Michael Crichton's conclusions on the matter of time travel.

The possibility if it exists is about as great a chance in probability as compared to the size of a single atom.

Tom not to put too finer a point on it but

Uncle Albert never actually tested any of his Hypothesis he just proved them mathematically and even then some where based on faulty assumptions which he latter had to fix when extermination proved him wrong.

Others turned some of Albert's Hypotheses into Theory's and then Scientific Law with our current Knowledge but even Albert accepted that as we gain more knowledge his assumptions will have to be changed so that the work remains relevant.

God I would have loved to actually meet the man rather than just study his work. His sense of Humor was even more warped than mine.

Well of course - I'd say that goes without saying..

by TomSal In reply to Tom not to put too finer ...

Perhaps as we advance (many many times over from our current understanding of the universe and its laws) possibilities will open. Heck if there is no progression through the ages then that's very very sad and actually dangerous to our species long term survival.

There also exists the concept of what would happen if say for argument's sake time travel was possible. I mean there are those that say it would "rip the fabric of reality and destroy the universe" kind of thing (ie. the uber Star Trekkie types..lol) and then the one that I personally think about...which is simply wouldn't it be INCREDIBLY dangerous to alter time. I mean what would happen if you went back and you change the course of your parents lives when they were your current age now? Or what if you met your younger self?

In movies it sounds cool, but in reality -- I don't see how something wouldn't get in two words --FARKED UP! :)

okay.

Have you tried to fly? I mean really tried?? And I brought up Crichton, not because he's an expert on it (he just writes sci-fi books) but because he put it in easy to understand terms. So even an idiot could get some idea of what we're talking about.

Yep..

by TomSal In reply to okay.

It's fun leaping off of high cliffs unassisted by anything man made...(include parachutes or any other safety equipment as I mentioned before)...in my calculations I figure the fall will be fun I just don't know what to do about that sudden stop though. :)

Well Tom you reach a Terminal Velocity

by HAL 9000 Moderator In reply to Yep..

Where the air resistance prevents you from falling any faster. It's a very long time since I had anything at all to do with people who jumped out of perfectly safe aircraft for the fun of it but I think that they claimed you only reached a speed around 200 MPH.

As I keep telling the Cops who pull me up for speeding "Speeding never hurt anyone it's just the sudden stop!" I haven't got a ticket that's stuck for over 15 years now.

Terminal Velocity and altitude

by JamesRL In reply to Well Tom you reach a Term ...

I watched an interesting program about the record attempts for free fall. They took weather ballons up to 100,000 ft and some crazy fool lept out.

Because Terminal velocity is based on the density of the atmosphere, its lower as you get closer to sea level. The danger is that at 100,000 feet you change pressure potentially faster than any suit can keep up. He ended up with black eyes if I recall correctly.

He was doing over 300 MPH in the upper atmosphere. But being so high with limited points of reference, it didn't feel as fast.

terminal velocity

is 120 mhp.

at 9.809m/s/s acceleration, with air resistance that is the maximum velocity a freely falling object can obtain.

levitation

by ITgirli In reply to Yep..

Would that be considered a form of flight?

Technical and Common Sense

by TomSal In reply to levitation

Yes you have a point - I believe most people; say like if you just asked someone walking by on the street that question they'd say levitation is a form of flight.

More technically speaking, they are different.
