Infinite Mass? So Rosie O’Donnell and Hillary Clinton can time travel? “Goodnight everyone, tip your waitresses and bartenders. And order the soup.”

There's a reason only light travels at the speed of light.

Our bodies would radiate into electromagnetic energy like we were an antenna. Had a physics professor outline the equations in answer to this question about 40 years ago ... but after 40 years I have forgotten his development.

Infinite mass?

Michael Moore is a “time lord” aka Doctor Who(dat)?

Time travel is impossible, if for no other reason than everything in the universe is MOVING.

Let’s say that you actually have a working ‘Time Machine’.

You step in, turn it on and go back or forward in time to some point.

You exit the time machine and find that you are in empty space, far from the earth or even the solar system or possibly the entire galaxy. You immediately die from lack of oxygen and freeze solid as rock within a few minutes.

Because the earth and the sun and the solar system and the galaxy are moving constantly, but you did not, you just traversed TIME and not SPACE.....................

an object with infinite mass?

1. my last date
2. my weight loss doctor
3. SorozNazi’s bank account (and Mein Kamph book library)
4. Moslem terrorists’ weapons arsenal
5. Mueller’s “investigation” crap
6. Pelousy/Gore/FakeInjunSquaw/Obama/Kasick/Flake lies
7. ?

Relativistic effects aside, as I understand it, if time travel requires an object of infinite mass...

I actually haven't had time to read the article yet. Posted then ran off to eat dinner. But time travel, at least to the future, doesn't require infinite mass. I can't imagine what they mean by that. Will read now and see. And, as I mentioned at the top, it happens everyday, all around us, to an almost imperceptible degree (only high accuracy atomic clocks can detect it).

All the inventors of time machines would be fighting on the doorstep of the US Patent Office on the day it opened to get patent #1. First to file would be the rule because no one can sort out first to invent when dealing with a time machine.

Aha!

But I went to the 9th Circuit Court and they just overturned all the laws of physics.

Just you try and get around those black robed magicians.

You can only remember the past, not the future.

Entropy determines the arrow of time. Watch someone making the opening shot in a game of pool, breaking up the original triangle. No law of physics is violated by running the tape backwards, except that going backwards, entropy decreases and you can tell immediately that the tape is running backwards.

Same thing if you watch a plane crash. You can immediately recognize when the tape is going backwards.

Quantum and new physics mean...”we dont know anything very well.” Publish all this hogwash on the back of theoretical constructs...infinite mass...(can never be achieved by definition...there is always one size bigger}....shut up and supersize my fries.

And that's why you need the "And Relative Dimension In Space" part of the TARDIS.

Hafele–Keating experiment

The Hafele–Keating experiment was a test of the theory of relativity.

In October 1971, Joseph C. Hafele, a physicist, and Richard E. Keating, an astronomer, took four cesium-beam atomic clocks aboard commercial airliners.

They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory.

When reunited, the three sets of clocks were found to disagree with one another, and their differences were consistent with the predictions of special and general relativity.

Kinematic time dilation

According to special relativity, the rate of a clock is greatest according to an observer who is at rest with respect to the clock.

In a frame of reference in which the clock is not at rest, the clock runs more slowly, as expressed by the Lorentz factor.

This effect, called time dilation, has been confirmed in many tests of special relativity, such as the Ives–Stilwell experiment and experimental testing of time dilation.[1]

Considering the Hafele–Keating experiment in a frame of reference at rest with respect to the center of the earth, a clock aboard the plane moving eastward, in the direction of the Earth’s rotation, had a greater velocity (resulting in a relative time loss) than one that remained on the ground, while a clock aboard the plane moving westward, against the Earth’s rotation, had a lower velocity than one on the ground.[2]

Gravitational time dilation

General relativity predicts an additional effect, in which an increase in gravitational potential due to altitude speeds the clocks up.

That is, clocks at higher altitude tick faster than clocks on Earth’s surface.

This effect has been confirmed in many tests of general relativity, such as the Pound–Rebka experiment and Gravity Probe A.

In the Hafele–Keating experiment, there was a slight increase in gravitational potential due to altitude that tended to speed the clocks back up.

Since the aircraft flew at roughly the same altitude in both directions, this effect was approximately the same for the two planes, but nevertheless it caused a difference in comparison to the clocks on the ground.[2]

When I was very young my mom took us to Holy Thursday high mass. The experience opened my eyes to many fine things ... including the concept of “infinite”.
