Which trophic level has highest energy?
According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level.
Does time exist without mass?
NO. At the beginning of our universe there was light speed energy and there was matter that had resting mass (matter) and thus could not travel at light speed. Time and space cannot exist without mass and mass cannot exist without spacetime. As gravity potential increases so too do the dementions of space and time.
Does time exist without space?
General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field.
Is time really a dimension?
Time is just as good a dimension as space is, as no matter how you boost yourself through space, you must always move forward through time. If time weren’t a dimension with the exact properties it possesses, special relativity would be invalid, and we could not construct spacetime to describe our Universe.
Is traveling back in time possible?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.
Why Time Machine is not possible?
One significant limitation of such a time machine is that it is only possible to go as far back in time as the initial creation of the machine; in essence, it is more of a path through time than it is a device that itself moves through time, and it would not allow the technology itself to be moved backward in time.
