Sure ya can. You just need to have the wallet for it.

I guess if you try hard enough to miss a point, you can  :neener:

Or gravity forces...

My brain hurts when I try to comprehend current theories.
Feynman's lectures are probably the most down to earth explanation of physics.  I can't think of anyone who's more transparently articulated the material.

The law of gravitation
The relation of mathematics and physics

The problem with theories is that they are just that: theories. An unproven explanation of something new or puzzling. Some people put too much faith in theories. The thing is, theories are really just a hypothesis that which a scientist came up with to explain the unexplainable. Scientists often put their own spin on things when they have no evidence to prove something in order to formulate a more "complete" theory.

...


A theory is used as the basis of calculations and the making/building of stuff. You're mixing it up with the word 'hypothesis'.
A hypothesis is unproven, but a theory is taken as 'the truth' (until a better theory comes around). Gravity is just theory - but I don't see anyone floating off into the sky.
A theory DOES have to have evidence to support it, otherwise it is a hypothesis. What you state is incorrect.
Here we are, living on top of a molten ball of rock, spinning around at a 1,000mph, orbiting a nuclear fireball and whizzing through space at half-a-million miles per hour. Most of us believe in super-beings which for some reason need to be praised for setting this up. This, apparently, is normal.

If history has taught us nothing else. It has taught us to never pay too much attention to naysayers.
Its never been a matter if if something can be done. But in finding the way to do it.

“This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us.” –Western Union internal memo, 1876

“Everyone acquainted with the subject will recognize it as a conspicuous failure.” –Henry Morton, President of the Stevens Institute of Technology, on Edison’s light bulb, 1880

“The horse is here to stay but the automobile is only a novelty, a fad.” –The President of the Michigan Savings Bank advising Henry Ford’s lawyer not to invest in the Ford Motor Co., 1903.

“Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.” –Simon Newcomb; The Wright Brothers flew at Kittyhawk 18 months later

“Drill for oil? You mean drill into the ground to try and find oil? You’re crazy.” –Associates of Edwin L. Drake mocking his idea to drill for oil, 1859.

“How, sir, would you make a ship sail against the wind and currents by lighting a bonfire under her deck? I pray you, excuse me, I have not the time to listen to such nonsense.” –Napoleon Bonaparte, when told of Robert Fulton’s steamboat plans, 1800s

“Very interesting Whittle, my boy, but it will never work.” –Cambridge Aeronautics Professor, when shown Frank Whittle’s plan for the jet engine.



And one of my all time favorites

“To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth – all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances.”

–Lee DeForest, Inventor of the vacuum tube, 1926.




Excellent Post. And very true..

Point was that theories are only abstract models. Not gospel. This inconclusiveness is fundamental to science's success.

All thought is abstract. Show me a model that isn't abstract.
It's the testability of a theory that shows it to be 'the current known truth'. Show us something else that works better than a theory that isn't 'just a theory'.

Ahh, I had no idea they had tested black holes, dark matter and how large objects bend gravity.  My bad  :neener:

A lot of his stuff does not work unless you add "constants".  In other words, manipulate the results of the formulas to match what we think the answer should have been.

In any case, these arguments are pointless.  We don;t have supersonic passenger planes anymore but we think we will be traveling to other planets or at the speed of light soon?  :rofl :rofl :rofl :rofl

one word, Einstein, ..nothing is faster the light, nothing. And physics never changed the last few years.
Read some books from Brian greene (theoretical physicist and one of the best-known string theorists around).

With one known exception.  Space itself.  Space is expanding and is not constrained by that law.  Space can in fact expand faster than the speed of light.

How weird is that?  :O

I got that from:

The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos
Brian Greene

Exactly - nothing can travel faster than light through space - but space itself easily expands faster than light.
