Gravity in terms of space-time

a complication in the relationship between strings and spacetime. String theory does not predict that the Einstein equations are obeyed exactly. String theory adds an infinite series of corrections to the theory of gravity. Under normal circumstances, if we only look at distance scales much larger than a string, then these corrections are not measurable. [...]
On the Existence of Time – Philosophy of Time
| No Reviews |
Overall Rating:

John McTaggart Ellis McTaggart put forth a seemingly convincing argument proposing the non-existence of time. McTaggart purports that for time to exist, it must have contradictory properties. McTaggart makes improper interpretations, and his defence does not answer the challenges put forth by others. Thus McTaggart’s unsound argument does not stand up to internal inspection nor [...]

The following is a theory presented considering the future possibility of the discovery of yet another planet in ‘our’ solar system. 21 years ago, Zecharia Sitchin (linguistic scholar & historian of ancient Hebrew, Sumerian, Akkadian, and other early Mesopotamian civilizations) published The 12Th Planet (1976) which discusses the periodic return to our solar system of a [...]

The encounters
of dwarf galaxies are typically billions of light years away, so these occurred
billions of years ago. However, some of these galaxies analyzed in the new
study are relatively close, only 166 million light years away, which means that
the process now observed in these has been in quite recent; speaking cosmically:
only 166 million years ago.

In an attempt to solve the problem of “Lost Dwarf galaxies”, two astronomers used the WM Keck Observatory to study a population of galaxies darker and lighter mass than all existing ones. Each composed by a 99 percent of dark matter. The results suggest that the problem of the Lost Dwarf galaxies is not as [...]

In Space with a Little HOBO
Astronauts working in spacesuits to build the Space Station may get even colder than the suit designers imagined. Measuring the effects of extremely low temperatures on astronauts was the first step in making a better space suit.
