These meters are temperature-controlled to stabilize meter readings; however, repetition studies (Aiken et al., 1998; Jentzsch, 2008) showed that the Burris gravity meter has a higher stability and experiences less tares (a sudden jump in a gravity reading) over long periods of time. Because ...
In such higher curvature scenario, we explore the effect of electromagnetic field on scalar field collapse. Our results reveal that the presence of a time dependent electromagnetic field requires an anisotropy in the background spacetime geometry and such anisotropic spacetime allows a collapsing ...
Other systems rely on tethering for load reduction (e.g., [242–246]). With such a system the entire human body has to perform less work as it would be in lower gravity; however, they are very cumbersome and thus only allow a very limited range of motion and application. 4.9.2 ...
We wished to know whether gravity has a direct physiologic role in establishing the auxin reverse fountain signaling system in primary roots. One of the major values of work on the ISS is the ability to remove unit gravity from growth conditions. This allows a comparison with earthbound experimen...
Likewise in cosmology, vacuum fluctuations are a quantum effect that we believe seeds galaxy formation, while the expanding space–time they live on can only be treated classically. In addition to the need for an effective theory that treats space–time in the classical limit, there has long ...
When you deal with massive bodies like the Earth, however, which has a mass of 6 x 1024kilograms (seeHow much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now. ...
This was the observational motivation that led to Einstein's Theory of General Relativity (GR), which he published in 1915. GR has a completely different take on the nature of gravity. Indeed, it has a completely different take on the nature of space and time. Or at least that is the ...
We consider two interacting systems when one is treated classically while the other system remains quantum. Consistent dynamics of this coupling has been shown to exist, and explored in the context of treating space-time classically. Here, we prove that
With a 36-meter crew spin radius, each 1 rpm spin change requires 16.5 meters per seconds of relative tangential ΔV, from either Dragon or Falcon. Dragon has 3.5 times Falcon’s mass but its Dracos have five times higher specific impulse than Falcon’s cold gas thrusters. Here I assume ...
It is hosted on the Zooniverse citizen-science platform.Footnote 3 The Zooniverse platform has fielded a workable crowdsourcing model (involving over 2.5 million people in more than four hundred projects since its inception) through which volunteers provide large-scale scientific data analysis. ...
