Ask Ethan: Is antigravity even possible?
Bigthink.com ^ | November 8, 2024

Posted on 11/21/2024 3:19:55 PM PST by mowowie

For as long as we’ve been thinking about journeying to other star systems and the planets and worlds that orbit them, we’ve been compelled to consider just how to keep human beings intact during any journey that would bridge the interstellar distances. While short trips through the zero-gravity environment of space might be feasible for humans, over longer time periods, human bodies suffer from all sorts of maladies: space blindness, bone density loss, muscle atrophy, and much more. While instantaneous teleportation or faster-than-light travel, either through a wormhole or via warp drive, might be satisfactory solutions for science fiction, when it comes to reality, we need a superior plan.

What sorts of options are there, either for antigravity or for artificial gravity, if we want to make such a solution realistic and feasible? Are there any that don’t violate the laws of general relativity themselves? That’s what Steven Fredman wants to know, asking:

“Antigravity and non-rotational artificial gravity have been a staple of science fiction for years. But if general relativity is correct (as it certainly seems to be), is anti-/artificial even theoretically possible? As I understand it, gravity is a manifestation of the curvature of spacetime. Could locally altering the shape of spacetime produce antigravity?”

Though I thought that this was a obscure article i should have known that the Red Badger already had this article covered...

Yes; Just as soon as the relationship between gravitons and electrons is established.

Rocky and Bullwinkle addressed this issue decades ago when Bullwinkle inherited a mine containing deposits of an anti-gravity element known as “Upsidaisium.”

LOL!!! I really needed that laugh!

“Upsidaisium.” - typical Bullwinkle.

R&B was my favorite cartoon as a very young whipper-snapper...and they had the absolute best writers.

The possibility of antigravity depends on our understanding of what gravity actually is, doesn’t it? And we just don’t know what it is.

Consider the account of Jesus walking on water. For those who believe in the historical and spiritual significance of Jesus/Yeshua, this event could be seen as a miraculous suspension of physical laws, including gravity. While some may dismiss it as myth, it’s worth noting that this figure—mythological or historical—has profoundly influenced the world in ways no other individual has. Could this suggest there’s more to the story than mere legend?

Even modern physicists admit that our understanding of reality is incomplete. Gravity, consciousness, and the very fabric of existence remain elusive. These gaps in knowledge leave open the possibility of phenomena that challenge our current scientific frameworks.

As an aside, I have a devout friend who assisted in exorcisms and claims to have witnessed possessed individuals levitate. He is deeply sincere, and while I trust his honesty, it’s possible that he may have been subjected to some form of spiritual manipulation, brainwashing, or gaslighting during those experiences. Such factors could distort perception or create powerful psychological effects. While he genuinely believes he saw what he described, whether it occurred as he perceived it remains uncertain.

If a person can be subjected to spiritual brainwashing or manipulation, who’s to say that what we define as reality itself might not be a form of spiritual manipulation? Perhaps reality, as we experience it, is a construct—something shaped or influenced by forces beyond our understanding. This idea challenges the very foundation of how we perceive the world and invites deeper reflection on the nature of existence, consciousness, and reality (including gravity) itself.

Just expressing my simple-minded thoughts on this.

I believe that gravity and time are intimately related.

Time-dilation occurs when traveliing near the speed of light beause of the propulsion force required to achieve the near light-speed velocity. The Gs observed in the acceleration are the same Gs exerted by gravity.

In my simple-minded opinion, if time-travel is possible then anti-gravity is possible, and vice-versa.

How can we ‘invent’ antigravity when we can’t even define gravity?.......

Faster than light speed travel? Perhaps. More probable is the instantaneous traversing of dimensions.
